+title: "Deployment Sizing"
+description: Choose the right deployment size for your crew workloads — and know when to scale up.
+---
+
+## Overview
+
+Every CrewAI Enterprise deployment runs on a fixed resource tier called an **instance size**. The size controls how much CPU, memory, and — most importantly — how many crew runs can execute simultaneously. Choosing the wrong size is the most common cause of queue build-up, slow run starts, and OOMKilled pods.
+
+This page explains what each size provides, how to read the signals that you've outgrown your current tier, and how to right-size for your workload.
+
+---
+
+## Instance Sizes
+
+| # | Name | vCPU | Memory | Max Concurrent Runs | Storage |
+|---|------|------|--------|---------------------|---------|
+| 1 | Small | 1 | 2 GiB | 4 | 20 GiB |
+| 2 | Regular | 2 | 4 GiB | 16 | 20 GiB |
+| 3 | Large | 4 | 8 GiB | 32 | 20 GiB |
+| 4 | Extra Large | 8 | 16 GiB | 64 | 100 GiB |
+| 5 | Extra Extra Large | 16 | 32 GiB | 128 | 100 GiB |
+| 6 | Insane Large | 32 | 64 GiB | 256 | 100 GiB |
+
+**vCPU** and **Memory** are the total resources allocated to the deployment (web server + workers + Redis combined).
+
+**Max Concurrent Runs** is the worker concurrency limit — the number of crew runs that can be actively executing at the same time. Runs submitted beyond this limit are queued and wait for a slot to open.
+
+<Note>
+  Concurrency is per-deployment, not per-crew. If you have 10 crews deployed on a Small instance, all 10 share the same pool of 4 concurrent run slots.
+</Note>
+
+---
+
+## What "concurrent runs" actually means
+
+A **concurrent run** is one active kickoff of a crew — from the moment it starts executing until it completes or errors. It does not mean the number of agents running in parallel inside a single crew (that's controlled by your crew's process type and agent configuration).
+
+**Example:** A Small deployment (concurrency = 4) with 20 incoming run requests will execute 4 runs simultaneously and queue the remaining 16. Each queued run starts as soon as a slot frees up.
+
+---
+
+## Symptoms of an undersized deployment
+
+| Symptom | Likely cause |
+|---------|-------------|
+| Runs sit in `queued` state for a long time | Concurrency limit reached — all worker slots are occupied |
+| Runs complete slowly even for simple tasks | CPU throttling — workers are competing for the same vCPU budget |
+| Pods restart with `OOMKilled` | Memory limit exceeded — reduce concurrency or upgrade size |
+| Builds fail or time out | Insufficient CPU/memory for the BuildKit image build step |
+| High p95/p99 run latency with normal p50 | Bursty traffic hitting the concurrency ceiling |
+
+---
+
+## How to choose a size
+
+### Start with your concurrency requirement
+
+Estimate the peak number of crew runs you expect to have in-flight simultaneously. Add ~25% headroom for bursts.
+
+| Peak concurrent runs | Recommended size |
+|----------------------|-----------------|
+| 1–3 | Small |
+| 4–12 | Regular |
+| 13–25 | Large |
+| 26–50 | Extra Large |
+| 51–100 | Extra Extra Large |
+| 100+ | Insane Large |
+
+### Factor in run duration
+
+Long-running crews (minutes to hours) hold concurrency slots for the full duration. If your crews run for 10 minutes on average and you receive 30 runs per hour, you need at least `30 × (10/60) = 5` concurrent slots — Regular or above.
+
+### Factor in memory per run
+
+Each concurrent run consumes memory proportional to the number of agents, the size of context windows, and any in-memory data processing. If individual runs are memory-heavy (large document processing, many parallel agents), size up even if your concurrency requirement is low.
+
+A rough heuristic: assume **~256 MiB per concurrent run** as a baseline, then add overhead for your specific workload. On a Small instance (2 GiB total, shared with web and Redis), you have roughly 1 GiB available for workers — enough for ~4 lightweight runs, which matches the concurrency limit.
+
+---
+
+## Changing your deployment size
+
+Deployment size is configurable from the **Admin Panel → Deployments → [your deployment] → Instance Size**. Changes take effect on the next deployment cycle (a rolling restart of the worker pods).
+
+<Warning>
+  Downsizing a deployment that is actively processing runs will cause in-flight runs to be interrupted when the old pods are replaced. Schedule size changes during low-traffic windows.
+</Warning>
+
+---
+
+## Monitoring utilization
+
+Use these signals to track whether your current size is appropriate:
+
+```bash
+# Check current pod resource usage
+kubectl top pods
+
+# Watch for OOMKilled restarts
+kubectl get pods -o wide
+kubectl describe pod <worker-pod-name> | grep -A5 "Last State"
+
+# Check worker queue depth (from a web pod)
+kubectl exec -it deploy/crewai-web -- bin/rails runner \
+  "puts Sidekiq::Queue.all.map { |q| \"#{q.name}: #{q.size}\" }.join(\"\\n\")"
+```
+
+A consistently non-zero queue depth on the default queue is the clearest signal that you need more concurrency (a larger instance size).

-title: Execution Boundary Hooks
-description: Intercept the start, inputs, output, and end of crew and flow executions with the @on decorator
-mode: "wide"
----
-
-Execution boundary hooks intercept the outermost edges of a run — before any
-work starts, when inputs are resolved, when the final result is ready, and when
-the execution finishes. They fire for both crews and flows and are the right
-place for run-level policy checks, input rewriting, and output sanitization.
-
-## Overview
-
-Four interception points cover the boundaries:
-
-| Point | When | `ctx.payload` |
-|-------|------|---------------|
-| `EXECUTION_START` | A crew or flow is about to begin | inputs `dict` |
-| `INPUT` | Resolved inputs for the execution | inputs `dict` |
-| `OUTPUT` | The final result is ready | the output object |
-| `EXECUTION_END` | The execution has finished | the output object |
-
-For a crew, the output payload is a `CrewOutput`. For a flow, it is the final
-flow-method result.
-
-## Hook Signature
-
-```python
-from crewai.hooks import on, HookAborted, InterceptionPoint
-
-@on(InterceptionPoint.EXECUTION_START)
-def boundary_hook(ctx) -> Any | None:
-    # Mutate ctx.payload in place, or
-    # return a non-None value to replace it, or
-    # raise HookAborted(reason, source) to stop the run
-    return None
-```
-
-Boundary hooks follow the standard contract: proceed (`return None`), mutate in
-place, replace by returning, or abort by raising
-[`HookAborted`](/edge/en/learn/execution-hooks#aborting-an-operation). An abort at any
-boundary propagates out of `kickoff()` with its reason.
-
-## Context Schema
-
-Each point receives a typed context. All contexts share the base fields:
-
-```python
-class InterceptionContext:
-    payload: Any            # The interceptable value (see table above)
-    agent: Any = None       # Not populated at execution boundaries
-    agent_role: str | None  # Not populated at execution boundaries
-    task: Any = None        # Not populated at execution boundaries
-    crew: Any = None        # The Crew instance (crew runs only)
-    flow: Any = None        # The Flow instance (flow runs only)
-```
-
-The per-point contexts add a named alias for the payload:
-
-```python
-class ExecutionStartContext(InterceptionContext):
-    inputs: dict            # Same dict as payload
-
-class InputContext(InterceptionContext):
-    inputs: dict            # Same dict as payload
-
-class OutputContext(InterceptionContext):
-    output: Any             # The output object
-
-class ExecutionEndContext(InterceptionContext):
-    output: Any             # The output object
-```
-
-<Note>
-`ctx.inputs` aliases the **original** inputs dict, so in-place edits through
-either name are equivalent. If an earlier hook *replaced* the payload by
-returning a new dict, only `ctx.payload` is rebound — always read and write
-`ctx.payload` when hooks might chain.
-</Note>
-
-## Crew Runs vs. Flow Runs
-
-Boundary hooks fire on both runtimes, and crew execution internally rides on a
-flow runtime. During a `crew.kickoff()`, a global boundary hook therefore fires
-for the crew boundary (`ctx.crew` set, `ctx.flow` `None`) **and** for the
-internal flow (`ctx.flow` set, `ctx.crew` `None`). Discriminate by runtime:
-
-```python
-@on(InterceptionPoint.OUTPUT)
-def crew_output_only(ctx):
-    if ctx.crew is None:
-        return None  # Skip the internal flow (or a bare flow)
-    ctx.payload.raw = ctx.payload.raw.strip()
-```
-
-## Common Use Cases
-
-### Policy Check at Start
-
-```python
-@on(InterceptionPoint.EXECUTION_START)
-def enforce_policy(ctx):
-    if ctx.crew is not None and not ctx.payload.get("authorized"):
-        raise HookAborted(reason="unauthorized execution", source="access-control")
-```
-
-### Input Rewriting
-
-```python
-@on(InterceptionPoint.INPUT)
-def add_defaults(ctx):
-    if ctx.crew is None:
-        return None
-    ctx.payload.setdefault("locale", "en-US")
-    ctx.payload["topic"] = ctx.payload["topic"].strip().lower()
-```
-
-Rewritten inputs flow into task interpolation, so the run behaves as if it was
-kicked off with the modified dict.
-
-### Output Sanitization
-
-```python
-import re
-
-@on(InterceptionPoint.OUTPUT)
-def redact_emails(ctx):
-    if ctx.crew is None:
-        return None
-    ctx.payload.raw = re.sub(
-        r"\b[\w.+-]+@[\w-]+\.[\w.]+\b", "[EMAIL-REDACTED]", ctx.payload.raw
-    )
-```
-
-`OUTPUT` runs before `EXECUTION_END`, and both see the (possibly replaced)
-payload from earlier hooks; the final rewritten value is what `kickoff()`
-returns.
-
-## Ordering
-
-For a crew run the boundary order is:
-
-```
-EXECUTION_START → before_kickoff callbacks → INPUT → tasks execute → OUTPUT → EXECUTION_END
-```
-
-Hooks at the same point run in registration order, global hooks first, then
-crew-scoped hooks. Telemetry (`HookDispatchedEvent`) is emitted per dispatch.
-
-## Managing Hooks in Tests
-
-```python
-from crewai.hooks import clear_all_hooks
-
-clear_all_hooks()  # Clears every point, including boundaries
-```

-Execution hooks provide fine-grained control over the runtime behavior of your
-CrewAI agents. Unlike kickoff hooks that run before and after crew execution,
-execution hooks intercept specific operations during execution — from the moment
-a run starts, through every model call, tool call, and task or flow-method step,

+Execution Hooks provide fine-grained control over the runtime behavior of your CrewAI agents. Unlike kickoff hooks that run before and after crew execution, execution hooks intercept specific operations during agent execution, allowing you to modify behavior, implement safety checks, and add comprehensive monitoring.
 
-Hooks are written with the `@on` decorator: one registration API and one
-contract cover every interception point in the framework.
+## Types of Execution Hooks
 
-```python
-from crewai.hooks import on, HookAborted, InterceptionPoint
+CrewAI provides two main categories of execution hooks:
 
-@on(InterceptionPoint.PRE_TOOL_CALL, tools=["delete_file"])
-def guard_deletes(ctx):
-    raise HookAborted(reason="file deletion is not allowed", source="policy")
-```

-<Note>
-The point-specific decorators (`@before_llm_call`, `@after_tool_call`, ...) keep
-working unchanged — they are adapters over the same engine. See
-[Point-specific decorators (legacy)](#point-specific-decorators-legacy) at the
-end of this page.

+Control and monitor language model interactions:
+- **Before LLM Call**: Modify prompts, validate inputs, implement approval gates
+- **After LLM Call**: Transform responses, sanitize outputs, update conversation history
 
-## The contract
+**Use Cases:**
+- Iteration limiting
+- Cost tracking and token usage monitoring
+- Response sanitization and content filtering
+- Human-in-the-loop approval for LLM calls
+- Adding safety guidelines or context
+- Debug logging and request/response inspection
 
-Every hook is a **synchronous** callable that receives a single typed context:

-def add_defaults(ctx):
-    # 1. Observe: read anything off the context.
-    # 2. Mutate in place: change ctx.payload or nested fields directly.
-    ctx.payload.setdefault("locale", "en-US")
-    # 3. Or replace: return a new value to swap ctx.payload.
-    # 4. Or abort: raise HookAborted(reason, source) to stop the operation.
-    return None

+Control and monitor tool execution:
+- **Before Tool Call**: Modify inputs, validate parameters, block dangerous operations
+- **After Tool Call**: Transform results, sanitize outputs, log execution details
 
-A hook may do any of four things:

+- Safety guardrails for destructive operations
+- Human approval for sensitive actions
+- Input validation and sanitization
+- Result caching and rate limiting
+- Tool usage analytics
+- Debug logging and monitoring

-def log_search_results(ctx):
-    print(f"search returned: {(ctx.tool_result or '')[:80]}")
-```
-
-Applied to a method inside a `@CrewBase` class, `@on` registers a
-**crew-scoped** hook, active only while that crew runs:
-
-```python
-from crewai import CrewBase
-from crewai.hooks import on, InterceptionPoint
-
-@CrewBase
-class MyProjCrew:
-    @on(InterceptionPoint.PRE_MODEL_CALL)
-    def validate_inputs(self, ctx):
-        # Only applies to this crew
-        return None
-```
-
-## Interception point catalog
-
-Each family has a detailed guide covering its context schema, payload
-semantics, and examples.
-
-### [Execution boundaries](/edge/en/learn/execution-boundary-hooks)
-
-| Point | When | `ctx.payload` |
-|-------|------|---------------|
-| `EXECUTION_START` | A crew or flow is about to begin | inputs `dict` |
-| `INPUT` | Resolved inputs for the execution | inputs `dict` |
-| `OUTPUT` | Final result is ready | the output object |
-| `EXECUTION_END` | A crew or flow has finished | the output object |
-
-### [Model boundaries](/edge/en/learn/llm-hooks) & [tool boundaries](/edge/en/learn/tool-hooks)
-
-| Point | When | Hook receives |
-|-------|------|---------------|
-| `PRE_MODEL_CALL` | Before an LLM call | `LLMCallHookContext` |
-| `POST_MODEL_CALL` | After an LLM call | `LLMCallHookContext` (with `response` set) |
-| `PRE_TOOL_CALL` | Before a tool runs | `ToolCallHookContext` |
-| `POST_TOOL_CALL` | After a tool runs | `ToolCallHookContext` (with results set) |
-
-At these four points the hook receives the rich legacy context **directly** as
-its argument — there is no separate `ctx.payload`. Mutate `ctx.messages` /
-`ctx.tool_input` in place, and return a string from a post hook to replace the
-response / tool result.
-
-### [Step points](/edge/en/learn/step-hooks)
-
-| Point | When | `ctx.payload` |
-|-------|------|---------------|
-| `PRE_STEP` | Before a task or flow-method step | step input |
-| `POST_STEP` | After a task or flow-method step | step output |
-
-`PRE_STEP` / `POST_STEP` carry `ctx.kind` (`"task"` or `"flow_method"`) and
-`ctx.step_name`.
-
-## Aborting an operation
-
-`HookAborted` carries a `reason` and an optional `source`. The `source` defaults
-to the aborting hook when omitted, which is useful for telemetry and failure
-messages:
-
-```python
-@on(InterceptionPoint.EXECUTION_START)
-def enforce_policy(ctx):
-    if not ctx.payload.get("authorized"):
-        raise HookAborted(reason="unauthorized execution", source="access-control")
-```
-
-## Composition, ordering, and fail-open
-
-- Multiple hooks on the same point run in **registration order**, global hooks
-  first, then execution-scoped hooks. Legacy hooks registered for the same point
-  participate in the same chain.
-- The (possibly mutated) payload flows from one hook to the next.
-- `HookAborted` **propagates by design** and stops the chain.
-- Any *other* exception raised by a hook is **swallowed** (fail-open) so a single
-  buggy hook can't crash a run.
-- When no hook is registered for a point, dispatch is a single dict lookup
-  (no-op fast path), so unused points cost effectively nothing.
-
-## Common patterns
-
-### Safety guardrails
-
-```python
-@on(InterceptionPoint.PRE_TOOL_CALL)
-def block_dangerous_tools(ctx):
-    dangerous = {"delete_file", "drop_table", "system_shutdown"}
-    if ctx.tool_name in dangerous:
-        raise HookAborted(reason=f"{ctx.tool_name} is blocked", source="safety-policy")
-
-@on(InterceptionPoint.PRE_MODEL_CALL)
-def iteration_limit(ctx):
-    if ctx.iterations > 15:
-        raise HookAborted(reason="maximum iterations exceeded", source="loop-guard")
-```
-
-### Human-in-the-loop approval
-
-```python
-@on(InterceptionPoint.PRE_TOOL_CALL, tools=["send_email", "make_payment"])
-def require_approval(ctx):
-    response = ctx.request_human_input(
-        prompt=f"Approve {ctx.tool_name}?",
-        default_message="Type 'yes' to approve:",
-    )
-    if response.lower() != "yes":
-        raise HookAborted(reason="rejected by operator", source="approval-gate")
-```
-
-### Sanitizing outputs
-
-A non-`None` return value replaces the interceptable value, so transformations
-are plain return statements:
-
-```python
-import re
-
-@on(InterceptionPoint.POST_MODEL_CALL)
-def redact_keys(ctx):
-    return re.sub(
-        r'(api[_-]?key)["\']?\s*[:=]\s*["\']?[\w-]+',
-        r"\1: [REDACTED]",
-        ctx.response,
-        flags=re.IGNORECASE,
-    )
-```
-
-### Observing steps
-
-```python
-@on(InterceptionPoint.POST_STEP)
-def trace_steps(ctx):
-    print(f"{ctx.kind} '{ctx.step_name}' finished")
-```
-
-## Telemetry
-
-Whenever a point actually dispatches to at least one hook, CrewAI emits a
-`HookDispatchedEvent` on the event bus with the point, the outcome
-(`proceeded` / `modified` / `aborted`), the hook count, the duration, and — for
-aborts — the reason and source. The no-op fast path emits nothing.
-
-## Managing hooks in tests
-
-Global hooks persist for the lifetime of the process. Reset them between tests:
-
-```python
-import pytest
-from crewai.hooks import clear_all_hooks
-
-@pytest.fixture(autouse=True)
-def reset_hooks():
-    clear_all_hooks()
-    yield
-    clear_all_hooks()
-```
-
-## Best practices
-
-1. **Keep hooks focused** — one clear responsibility per hook; register several
-   small hooks rather than one that does everything.
-2. **Keep hooks fast** — hooks run on every dispatch of their point; avoid heavy
-   computation and lazy-import heavy dependencies.
-3. **Prefer scoping** — use `agents=` / `tools=` filters and crew-scoped
-   registration instead of unconditional global hooks.
-4. **Abort loudly** — raise `HookAborted` with a meaningful `reason` and
-   `source`; that context surfaces in error messages and telemetry. Remember
-   that any other exception is swallowed (fail-open), so don't rely on raising
-   `ValueError` to stop a run.
-
-## Point-specific decorators (legacy)
-
-Before `@on`, LLM and tool calls were hooked with dedicated decorator pairs.
-These keep working unchanged — they are adapters over the same dispatcher, so
-they compose with `@on` hooks in the same registration-order chain:
+The cleanest and most Pythonic way to register hooks:
 
 ```python
 from crewai.hooks import before_llm_call, after_llm_call, before_tool_call, after_tool_call
 
 @before_llm_call
 def limit_iterations(context):
+    """Prevent infinite loops by limiting iterations."""
     if context.iterations > 10:
         return False  # Block execution
+    return None
+
+@after_llm_call
+def sanitize_response(context):
+    """Remove sensitive data from LLM responses."""
+    if "API_KEY" in context.response:
+        return context.response.replace("API_KEY", "[REDACTED]")
+    return None
+
+@before_tool_call
+def block_dangerous_tools(context):
+    """Block destructive operations."""
+    if context.tool_name == "delete_database":
+        return False  # Block execution
+    return None
 
 @after_tool_call
 def log_tool_result(context):
+    """Log tool execution."""
     print(f"Tool {context.tool_name} completed")
+    return None
 ```
 
-Differences from `@on`:
+### 2. Crew-Scoped Hooks
 
-- They cover **only** the four model/tool points — no execution boundaries, no
-  steps.
-- Blocking is `return False`, with no abort reason or source attached.
-- They receive the same rich contexts — `LLMCallHookContext` (with full
-  executor access) and `ToolCallHookContext` — that `@on` hooks receive at the
-  model/tool points.
-- Crew-scoping works the same way: apply the decorator to a method inside a
-  `@CrewBase` class.
-- They support the same `agents=` / `tools=` filters.
+Apply hooks only to specific crew instances:
 
-You might still prefer them for existing codebases that already use
-`return False` semantics, or when you want the point-specific typed signatures.

+```
+Agent needs to call LLM
+    ↓
+[Before LLM Call Hooks Execute]
+    ├→ Hook 1: Validate iteration count
+    ├→ Hook 2: Add safety context
+    └→ Hook 3: Log request
+    ↓
+If any hook returns False:
+    ├→ Block LLM call
+    └→ Raise ValueError
+    ↓
+If all hooks return True/None:
+    ├→ LLM call proceeds
+    └→ Response generated
+    ↓
+[After LLM Call Hooks Execute]
+    ├→ Hook 1: Sanitize response
+    ├→ Hook 2: Log response
+    └→ Hook 3: Update metrics
+    ↓
+Final response returned
+```
+
+### Tool Call Flow
+
+```
+Agent needs to execute tool
+    ↓
+[Before Tool Call Hooks Execute]
+    ├→ Hook 1: Check if tool is allowed
+    ├→ Hook 2: Validate inputs
+    └→ Hook 3: Request approval if needed
+    ↓
+If any hook returns False:
+    ├→ Block tool execution
+    └→ Return error message
+    ↓
+If all hooks return True/None:
+    ├→ Tool execution proceeds
+    └→ Result generated
+    ↓
+[After Tool Call Hooks Execute]
+    ├→ Hook 1: Sanitize result
+    ├→ Hook 2: Cache result
+    └→ Hook 3: Log metrics
+    ↓
+Final result returned
+```
+
+## Hook Context Objects
+
+### LLMCallHookContext
+
+Provides access to LLM execution state:
+
+```python
+class LLMCallHookContext:
+    executor: CrewAgentExecutor  # Full executor access
+    messages: list               # Mutable message list
+    agent: Agent                 # Current agent
+    task: Task                   # Current task
+    crew: Crew                   # Crew instance
+    llm: BaseLLM                 # LLM instance
+    iterations: int              # Current iteration
+    response: str | None         # LLM response (after hooks)
+```
+
+### ToolCallHookContext
+
+Provides access to tool execution state:
+
+```python
+class ToolCallHookContext:
+    tool_name: str               # Tool being called
+    tool_input: dict             # Mutable input parameters
+    tool: CrewStructuredTool     # Tool instance
+    agent: Agent | None          # Agent executing
+    task: Task | None            # Current task
+    crew: Crew | None            # Crew instance
+    tool_result: str | None      # Agent-facing result string (after hooks)
+    raw_tool_result: Any | None  # Raw Python result (after hooks)
+```
+
+For typed tool outputs, `tool_result` is the string the agent sees. By default, this is JSON. If the tool uses custom formatting, it can be Markdown or another string. `raw_tool_result` is the original Python value returned by the tool.
+
+## Common Patterns
+
+### Safety and Validation
+
+```python
+@before_tool_call
+def safety_check(context):
+    """Block destructive operations."""
+    dangerous = ['delete_file', 'drop_table', 'system_shutdown']
+    if context.tool_name in dangerous:
+        print(f"🛑 Blocked: {context.tool_name}")
+        return False
+    return None
+
+@before_llm_call
+def iteration_limit(context):
+    """Prevent infinite loops."""
+    if context.iterations > 15:
+        print("⛔ Maximum iterations exceeded")
+        return False
+    return None
+```
+
+### Human-in-the-Loop
+
+```python
+@before_tool_call
+def require_approval(context):
+    """Require approval for sensitive operations."""
+    sensitive = ['send_email', 'make_payment', 'post_message']
+
+    if context.tool_name in sensitive:
+        response = context.request_human_input(
+            prompt=f"Approve {context.tool_name}?",
+            default_message="Type 'yes' to approve:"
+        )
+
+        if response.lower() != 'yes':
+            return False
+
+    return None
+```
+
+### Monitoring and Analytics
+
+```python
+from collections import defaultdict
+import time
+
+metrics = defaultdict(lambda: {'count': 0, 'total_time': 0})
+
+@before_tool_call
+def start_timer(context):
+    context.tool_input['_start'] = time.time()
+    return None
+
+@after_tool_call
+def track_metrics(context):
+    start = context.tool_input.get('_start', time.time())
+    duration = time.time() - start
+
+    metrics[context.tool_name]['count'] += 1
+    metrics[context.tool_name]['total_time'] += duration
+
+    return None
+
+# View metrics
+def print_metrics():
+    for tool, data in metrics.items():
+        avg = data['total_time'] / data['count']
+        print(f"{tool}: {data['count']} calls, {avg:.2f}s avg")
+```
+
+### Response Sanitization
+
+```python
+import re
+
+@after_llm_call
+def sanitize_llm_response(context):
+    """Remove sensitive data from LLM responses."""
+    if not context.response:
+        return None
+
+    result = context.response
+    result = re.sub(r'(api[_-]?key)["\']?\s*[:=]\s*["\']?[\w-]+',
+                   r'\1: [REDACTED]', result, flags=re.IGNORECASE)
+    return result
+
+@after_tool_call
+def sanitize_tool_result(context):
+    """Remove sensitive data from tool results."""
+    if not context.tool_result:
+        return None
+
+    result = context.tool_result
+    result = re.sub(r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b',
+                   '[EMAIL-REDACTED]', result)
+    return result
+```
+
+## Hook Management
+
+### Clearing All Hooks
+
+```python
+from crewai.hooks import clear_all_global_hooks
+
+# Clear all hooks at once
+result = clear_all_global_hooks()
+print(f"Cleared {result['total']} hooks")
+# Output: {'llm_hooks': (2, 1), 'tool_hooks': (1, 2), 'total': (3, 3)}
+```
+
+### Clearing Specific Hook Types
+
+```python
+from crewai.hooks import (
+    clear_before_llm_call_hooks,
+    clear_after_llm_call_hooks,
+    clear_before_tool_call_hooks,
+    clear_after_tool_call_hooks
+)
+
+# Clear specific types
+llm_before_count = clear_before_llm_call_hooks()
+tool_after_count = clear_after_tool_call_hooks()
+```
+
+### Unregistering Individual Hooks
+
+```python
+from crewai.hooks import (
+    unregister_before_llm_call_hook,
+    unregister_after_tool_call_hook
+)
+
+def my_hook(context):
+    ...
+
+# Register
+register_before_llm_call_hook(my_hook)
+
+# Later, unregister
+success = unregister_before_llm_call_hook(my_hook)
+print(f"Unregistered: {success}")
+```
+
+## Best Practices
+
+### 1. Keep Hooks Focused
+Each hook should have a single, clear responsibility:
+
+```python
+# ✅ Good - focused responsibility
+@before_tool_call
+def validate_file_path(context):
+    if context.tool_name == 'read_file':
+        if '..' in context.tool_input.get('path', ''):
+            return False
+    return None
+
+# ❌ Bad - too many responsibilities
+@before_tool_call
+def do_everything(context):
+    # Validation + logging + metrics + approval...
+    ...
+```
+
+### 2. Handle Errors Gracefully
+
+```python
+@before_llm_call
+def safe_hook(context):
+    try:
+        # Your logic
+        if some_condition:
+            return False
+    except Exception as e:
+        print(f"Hook error: {e}")
+        return None  # Allow execution despite error
+```
+
+### 3. Modify Context In-Place
+
+```python
+# ✅ Correct - modify in-place
+@before_llm_call
+def add_context(context):
+    context.messages.append({"role": "system", "content": "Be concise"})
+
+# ❌ Wrong - replaces reference
+@before_llm_call
+def wrong_approach(context):
+    context.messages = [{"role": "system", "content": "Be concise"}]
+```
+
+### 4. Use Type Hints
+
+```python
+from crewai.hooks import LLMCallHookContext, ToolCallHookContext
+
+def my_llm_hook(context: LLMCallHookContext) -> bool | None:
+    # IDE autocomplete and type checking
+    return None
+
+def my_tool_hook(context: ToolCallHookContext) -> str | None:
+    return None
+```
+
+### 5. Clean Up in Tests
+
+```python
+import pytest
+from crewai.hooks import clear_all_global_hooks
+
+@pytest.fixture(autouse=True)
+def clean_hooks():
+    """Reset hooks before each test."""
+    yield
+    clear_all_global_hooks()
+```
+
+## When to Use Which Hook
+
+### Use LLM Hooks When:
+- Implementing iteration limits
+- Adding context or safety guidelines to prompts
+- Tracking token usage and costs
+- Sanitizing or transforming responses
+- Implementing approval gates for LLM calls
+- Debugging prompt/response interactions
+
+### Use Tool Hooks When:
+- Blocking dangerous or destructive operations
+- Validating tool inputs before execution
+- Implementing approval gates for sensitive actions
+- Caching tool results
+- Tracking tool usage and performance
+- Sanitizing tool outputs
+- Rate limiting tool calls
+
+### Use Both When:
+Building comprehensive observability, safety, or approval systems that need to monitor all agent operations.
+
+## Alternative Registration Methods
+
+### Programmatic Registration (Advanced)
+
+For dynamic hook registration or when you need to register hooks programmatically:
+
+```python
+from crewai.hooks import (
+    register_before_llm_call_hook,
+    register_after_tool_call_hook
+)
+
+def my_hook(context):
+    return None
+
+# Register programmatically
+register_before_llm_call_hook(my_hook)
+
+# Useful for:
+# - Loading hooks from configuration
+# - Conditional hook registration
+# - Plugin systems
+```
+
+**Note:** For most use cases, decorators are cleaner and more maintainable.
+
+## Performance Considerations
+
+1. **Keep Hooks Fast**: Hooks execute on every call - avoid heavy computation
+2. **Cache When Possible**: Store expensive validations or lookups
+3. **Be Selective**: Use crew-scoped hooks when global hooks aren't needed
+4. **Monitor Hook Overhead**: Profile hook execution time in production
+5. **Lazy Import**: Import heavy dependencies only when needed
+
+## Debugging Hooks
+
+### Enable Debug Logging
+
+```python
+import logging
+
+logging.basicConfig(level=logging.DEBUG)
+logger = logging.getLogger(__name__)
+
+@before_llm_call
+def debug_hook(context):
+    logger.debug(f"LLM call: {context.agent.role}, iteration {context.iterations}")
+    return None
+```
+
+### Hook Execution Order
+
+Hooks execute in registration order. If a before hook returns `False`, subsequent hooks don't execute:
+
+```python
+# Register order matters!
+register_before_tool_call_hook(hook1)  # Executes first
+register_before_tool_call_hook(hook2)  # Executes second
+register_before_tool_call_hook(hook3)  # Executes third
+
+# If hook2 returns False:
+# - hook1 executed
+# - hook2 executed and returned False
+# - hook3 NOT executed
+# - Tool call blocked
+```

+## Conclusion
+
+Execution hooks provide powerful control over agent runtime behavior. Use them to implement safety guardrails, approval workflows, comprehensive monitoring, and custom business logic. Combined with proper error handling, type safety, and performance considerations, hooks enable production-ready, secure, and observable agent systems.

-## Custom OpenAI-Compatible Endpoints
-
-Many providers and local servers (Ollama, vLLM, LM Studio, llama.cpp, LiteLLM proxies, and hosted gateways) expose an **OpenAI-compatible** API. Instead of routing these through LiteLLM, you can talk to them directly with CrewAI's native OpenAI integration by setting `custom_openai=True`.
-
-This is the recommended replacement for any LiteLLM provider that offers an OpenAI-compatible endpoint.
-
-### How it works
-
-- `custom_openai=True` forces CrewAI to use the native OpenAI SDK, regardless of the model name.
-- The model ID is passed to the endpoint without validation against OpenAI's known-model list. This lets you use arbitrary model IDs your gateway expects (for example, `anthropic/claude-sonnet-4-6` served behind an OpenAI-compatible proxy). An optional leading `openai/` routing prefix is stripped.
-- A base URL is **required**. CrewAI resolves it, in order, from:
-  1. `base_url=...`
-  2. `api_base=...`
-  3. `OPENAI_BASE_URL` environment variable
-  4. `OPENAI_API_BASE` environment variable (legacy)
-
-  If none are set, CrewAI raises a `ValueError` so misconfiguration fails fast instead of silently hitting `api.openai.com`.

-<Tip>
-  If you use the `openai/` prefix with a model that isn't a known OpenAI model and pass `base_url` or `api_base` directly, CrewAI automatically treats it as a custom OpenAI-compatible endpoint. Environment variables alone do not enable automatic routing for unknown models; set `custom_openai=True` when configuring the endpoint through `OPENAI_BASE_URL` or `OPENAI_API_BASE`.

+LLM Call Hooks provide fine-grained control over language model interactions during agent execution. These hooks allow you to intercept LLM calls, modify prompts, transform responses, implement approval gates, and add custom logging or monitoring.
 
 ## Overview
 
-LLM hooks are executed at two interception points:
+LLM hooks are executed at two critical points:
+- **Before LLM Call**: Modify messages, validate inputs, or block execution
+- **After LLM Call**: Transform responses, sanitize outputs, or modify conversation history
 
-| Point | When | Hook receives |
-|-------|------|---------------|
-| `PRE_MODEL_CALL` | Before every LLM call | `LLMCallHookContext` |
-| `POST_MODEL_CALL` | After every LLM call | `LLMCallHookContext` (with `response` set) |
+## Hook Types
 
-Write them with the [`@on` decorator](/edge/en/learn/execution-hooks). The
-[legacy `@before_llm_call` / `@after_llm_call` decorators](#legacy-decorators)
-keep working unchanged — both styles register on the same engine and run in one
-ordered chain.
+### Before LLM Call Hooks
 
-## Hook Signature
+Executed before every LLM call, these hooks can:
+- Inspect and modify messages sent to the LLM
+- Block LLM execution based on conditions
+- Implement rate limiting or approval gates
+- Add context or system messages
+- Log request details
 
+**Signature:**
 ```python
-from crewai.hooks import on, HookAborted, InterceptionPoint, LLMCallHookContext
-
-@on(InterceptionPoint.PRE_MODEL_CALL)
-def before_hook(ctx: LLMCallHookContext) -> None:
-    # Mutate ctx.messages in place, or
-    # raise HookAborted(reason, source) to block the call
-    ...
-
-@on(InterceptionPoint.POST_MODEL_CALL)
-def after_hook(ctx: LLMCallHookContext) -> str | None:
-    # Return a string to replace ctx.response
-    # Return None to keep the original response
+def before_hook(context: LLMCallHookContext) -> bool | None:
+    # Return False to block execution
+    # Return True or None to allow execution
     ...
 ```
 
-Unlike the boundary and step points, the model-call points pass the rich
-`LLMCallHookContext` directly as the hook argument (there is no separate
-`ctx.payload`): mutate `ctx.messages` in place before the call, and return a
-string to replace the response after it.
+### After LLM Call Hooks
 
-Blocking a call raises `ValueError("LLM call blocked by before_llm_call hook")`
-inside the executor; the `HookAborted` reason and source are recorded in
-[telemetry](/edge/en/learn/execution-hooks#telemetry).
+Executed after every LLM call, these hooks can:
+- Modify or sanitize LLM responses
+- Add metadata or formatting
+- Log response details
+- Update conversation history
+- Implement content filtering
+
+**Signature:**
+```python
+def after_hook(context: LLMCallHookContext) -> str | None:
+    # Return modified response string
+    # Return None to keep original response
+    ...

 ### Modifying Messages
 
 **Important:** Always modify messages in-place:

 ## Registration Methods

+### 1. Global Hook Registration
 
-Apply to all LLM calls across all crews. Use the `agents=` filter to scope a
-hook to specific agent roles:
+Register hooks that apply to all LLM calls across all crews:
 
 ```python
-from crewai.hooks import on, InterceptionPoint
+from crewai.hooks import register_before_llm_call_hook, register_after_llm_call_hook
 
-@on(InterceptionPoint.PRE_MODEL_CALL)
-def log_llm_call(ctx):
-    print(f"LLM call by {ctx.agent.role} at iteration {ctx.iterations}")
+def log_llm_call(context):
+    print(f"LLM call by {context.agent.role} at iteration {context.iterations}")
+    return None  # Allow execution

-def log_researcher_responses(ctx):
-    print(f"Response length: {len(ctx.response)}")
+register_before_llm_call_hook(log_llm_call)
 ```
 
-### 2. Crew-Scoped Hooks
+### 2. Decorator-Based Registration
 
-Apply the same decorator to a method inside a `@CrewBase` class to scope the
-hook to that crew only:
-
-```python
-from crewai.hooks import on, InterceptionPoint
-
-@CrewBase
-class MyProjCrew:
-    @on(InterceptionPoint.PRE_MODEL_CALL)
-    def validate_inputs(self, ctx):
-        # Only applies to this crew
-        if ctx.iterations == 0:
-            print(f"Starting task: {ctx.task.description}")
-
-    @crew
-    def crew(self) -> Crew:
-        return Crew(agents=self.agents, tasks=self.tasks, process=Process.sequential)
-```
-
-## Common Use Cases
-
-### 1. Iteration Limiting
-
-```python
-@on(InterceptionPoint.PRE_MODEL_CALL)
-def limit_iterations(ctx: LLMCallHookContext) -> None:
-    if ctx.iterations > 15:
-        raise HookAborted(reason="exceeded 15 iterations", source="loop-guard")
-```
-
-### 2. Human Approval Gate
-
-```python
-@on(InterceptionPoint.PRE_MODEL_CALL)
-def require_approval(ctx: LLMCallHookContext) -> None:
-    if ctx.iterations > 5:
-        response = ctx.request_human_input(
-            prompt=f"Iteration {ctx.iterations}: Approve LLM call?",
-            default_message="Press Enter to approve, or type 'no' to block:",
-        )
-        if response.lower() == "no":
-            raise HookAborted(reason="blocked by user", source="approval-gate")
-```
-
-### 3. Adding System Context
-
-```python
-@on(InterceptionPoint.PRE_MODEL_CALL)
-def add_guardrails(ctx: LLMCallHookContext) -> None:
-    ctx.messages.append({
-        "role": "system",
-        "content": "Ensure responses are factual and cite sources when possible."
-    })
-```
-
-### 4. Response Sanitization
-
-```python
-import re
-
-@on(InterceptionPoint.POST_MODEL_CALL)
-def sanitize_sensitive_data(ctx: LLMCallHookContext) -> str | None:
-    if not ctx.response:
-        return None
-    sanitized = re.sub(r'\b\d{3}-\d{2}-\d{4}\b', '[SSN-REDACTED]', ctx.response)
-    return re.sub(r'\b\d{4}[- ]?\d{4}[- ]?\d{4}[- ]?\d{4}\b', '[CARD-REDACTED]', sanitized)
-```
-
-### 5. Debug Logging
-
-```python
-@on(InterceptionPoint.PRE_MODEL_CALL)
-def debug_request(ctx: LLMCallHookContext) -> None:
-    print(f"Agent: {ctx.agent.role}, iteration {ctx.iterations}, "
-          f"{len(ctx.messages)} messages")
-
-@on(InterceptionPoint.POST_MODEL_CALL)
-def debug_response(ctx: LLMCallHookContext) -> None:
-    if ctx.response:
-        print(f"Response preview: {ctx.response[:100]}...")
-```
-
-## Hook Management
-
-```python
-from crewai.hooks import (
-    InterceptionPoint,
-    clear_all_hooks,
-    clear_hooks,
-    get_hooks,
-    unregister_hook,
-)
-
-# Unregister a specific hook
-unregister_hook(InterceptionPoint.PRE_MODEL_CALL, my_hook)
-
-# Clear one point, or everything (e.g. between tests)
-clear_hooks(InterceptionPoint.POST_MODEL_CALL)
-clear_all_hooks()
-
-# Inspect what's registered
-print(len(get_hooks(InterceptionPoint.PRE_MODEL_CALL)))
-```
-
-The legacy management API (`register_before_llm_call_hook`,
-`unregister_before_llm_call_hook`, `clear_before_llm_call_hooks`,
-`clear_all_llm_call_hooks`, `get_before_llm_call_hooks`, and their `after_`
-counterparts) operates on the same underlying registries, so either API can
-manage hooks registered by the other.

-  `HookAborted`, but without a custom reason or source for telemetry.

-  hooks return `str | None`. The context object is the same

+
+## Hook Management
+
+### Unregistering Hooks
+
+```python
+from crewai.hooks import (
+    unregister_before_llm_call_hook,
+    unregister_after_llm_call_hook
+)
+
+# Unregister specific hook
+def my_hook(context):
+    ...
+
+register_before_llm_call_hook(my_hook)
+# Later...
+unregister_before_llm_call_hook(my_hook)  # Returns True if found
+```
+
+### Clearing Hooks
+
+```python
+from crewai.hooks import (
+    clear_before_llm_call_hooks,
+    clear_after_llm_call_hooks,
+    clear_all_llm_call_hooks
+)
+
+# Clear specific hook type
+count = clear_before_llm_call_hooks()
+print(f"Cleared {count} before hooks")
+
+# Clear all LLM hooks
+before_count, after_count = clear_all_llm_call_hooks()
+print(f"Cleared {before_count} before and {after_count} after hooks")
+```
+
+### Listing Registered Hooks
+
+```python
+from crewai.hooks import (
+    get_before_llm_call_hooks,
+    get_after_llm_call_hooks
+)
+
+# Get current hooks
+before_hooks = get_before_llm_call_hooks()
+after_hooks = get_after_llm_call_hooks()
+
+print(f"Registered: {len(before_hooks)} before, {len(after_hooks)} after")
+```
+
+## Advanced Patterns
+
+### Conditional Hook Execution
+
+```python
+@before_llm_call
+def conditional_blocking(context: LLMCallHookContext) -> bool | None:
+    # Only block for specific agents
+    if context.agent.role == "researcher" and context.iterations > 10:
+        return False
+
+    # Only block for specific tasks
+    if "sensitive" in context.task.description.lower() and context.iterations > 5:
+        return False
+
+    return None
+```
+
+### Context-Aware Modifications
+
+```python
+@before_llm_call
+def adaptive_prompting(context: LLMCallHookContext) -> None:
+    # Add different context based on iteration
+    if context.iterations == 0:
+        context.messages.append({
+            "role": "system",
+            "content": "Start with a high-level overview."
+        })
+    elif context.iterations > 3:
+        context.messages.append({
+            "role": "system",
+            "content": "Focus on specific details and provide examples."
+        })
+    return None
+```
+
+### Chaining Hooks
+
+```python
+# Multiple hooks execute in registration order
+
+@before_llm_call

 ## Best Practices
 
-1. **Keep hooks focused and fast** — they run on every LLM call
-2. **Modify in-place** — always mutate `ctx.messages`, never replace the list
-3. **Use type hints** — annotate with `LLMCallHookContext` for IDE support
-4. **Abort loudly** — raise `HookAborted` with a meaningful reason and source;
-   any other exception is swallowed (fail-open)
-5. **Clear hooks in tests** — call `clear_all_hooks()` between test runs
+1. **Keep Hooks Focused**: Each hook should have a single responsibility
+2. **Avoid Heavy Computation**: Hooks execute on every LLM call
+3. **Handle Errors Gracefully**: Use try-except to prevent hook failures from breaking execution
+4. **Use Type Hints**: Leverage `LLMCallHookContext` for better IDE support
+5. **Document Hook Behavior**: Especially for blocking conditions
+6. **Test Hooks Independently**: Unit test hooks before using in production
+7. **Clear Hooks in Tests**: Use `clear_all_llm_call_hooks()` between test runs
+8. **Modify In-Place**: Always modify `context.messages` in-place, never replace
+
+## Error Handling
+
+```python
+@before_llm_call
+def safe_hook(context: LLMCallHookContext) -> bool | None:
+    try:
+        # Your hook logic
+        if some_condition:
+            return False
+    except Exception as e:
+        print(f"⚠️ Hook error: {e}")
+        # Decide: allow or block on error
+        return None  # Allow execution despite error
+```
+
+## Type Safety
+
+```python
+from crewai.hooks import LLMCallHookContext, BeforeLLMCallHookType, AfterLLMCallHookType
+
+# Explicit type annotations
+def my_before_hook(context: LLMCallHookContext) -> bool | None:
+    return None
+
+def my_after_hook(context: LLMCallHookContext) -> str | None:
+    return None
+
+# Type-safe registration
+register_before_llm_call_hook(my_before_hook)
+register_after_llm_call_hook(my_after_hook)
+```
 
 ## Troubleshooting
 
 ### Hook Not Executing
-- Verify the hook is registered before crew execution
-- Check whether an earlier hook aborted (subsequent hooks don't run)
+- Verify hook is registered before crew execution
+- Check if previous hook returned `False` (blocks subsequent hooks)
+- Ensure hook signature matches expected type
 
 ### Message Modifications Not Persisting
-- Use in-place modifications: `ctx.messages.append(...)`
-- Don't replace the list: `ctx.messages = []`
+- Use in-place modifications: `context.messages.append()`
+- Don't replace the list: `context.messages = []`
 
 ### Response Modifications Not Working
-- Return the modified string from a `POST_MODEL_CALL` hook
+- Return the modified string from after hooks
 - Returning `None` keeps the original response

-title: Step Hooks
-description: Intercept task and flow-method steps with PRE_STEP and POST_STEP hooks in CrewAI
-mode: "wide"
----
-
-Step hooks intercept each unit of work inside an execution: every crew **task**
-and every **flow method**. Use them to inspect or rewrite what goes into a
-step, transform what comes out, or trace step-by-step progress — without
-touching the level of individual LLM or tool calls.
-
-## Overview
-
-Two interception points cover steps:
-
-| Point | When | `ctx.payload` |
-|-------|------|---------------|
-| `PRE_STEP` | Before a task or flow method runs | step input (see below) |
-| `POST_STEP` | After a task or flow method runs | step output (see below) |
-
-What the payload holds depends on `ctx.kind`:
-
-| `ctx.kind` | `PRE_STEP` payload | `POST_STEP` payload |
-|------------|--------------------|---------------------|
-| `"task"` | The context string passed to the agent | The `TaskOutput` object |
-| `"flow_method"` | The method's parameters as a `dict` | The method's return value |
-
-For flow methods, positional arguments appear in the params dict under `_0`,
-`_1`, ... keys and keyword arguments under their own names; edits and
-replacements are mapped back onto the actual call.
-
-## Hook Signature
-
-```python
-from crewai.hooks import on, HookAborted, InterceptionPoint
-
-@on(InterceptionPoint.PRE_STEP)
-def step_hook(ctx) -> Any | None:
-    # Mutate ctx.payload in place, or
-    # return a non-None value to replace it, or
-    # raise HookAborted(reason, source) to stop the step
-    return None
-```
-
-## Context Schema
-
-Both points receive a `StepContext`:
-
-```python
-class StepContext(InterceptionContext):
-    payload: Any            # Step input (pre) or step output (post)
-    kind: str | None        # "task" or "flow_method"
-    step_name: str | None   # Task name/description, or flow method name
-    output: Any             # POST_STEP only: same object as payload
-    agent: Any              # Task steps: the executing agent (else None)
-    agent_role: str | None  # Task steps: the agent's role (else None)
-    task: Any               # Task steps: the Task instance (else None)
-    crew: Any               # None for step points
-    flow: Any               # Flow-method steps: the Flow instance (else None)
-```
-
-For task steps, `step_name` is the task's `name` (falling back to its
-description). For flow-method steps, it is the method name.
-
-## Common Use Cases
-
-### Step Tracing
-
-```python
-@on(InterceptionPoint.POST_STEP)
-def trace_steps(ctx):
-    print(f"{ctx.kind} '{ctx.step_name}' finished")
-```
-
-### Rewriting Task Context
-
-```python
-@on(InterceptionPoint.PRE_STEP)
-def inject_disclaimer(ctx):
-    if ctx.kind != "task":
-        return None
-    return f"{ctx.payload}\n\nNote: treat all figures as estimates."
-```
-
-### Transforming Task Output
-
-```python
-@on(InterceptionPoint.POST_STEP)
-def normalize_output(ctx):
-    if ctx.kind != "task":
-        return None
-    ctx.payload.raw = ctx.payload.raw.strip()
-```
-
-<Note>
-`POST_STEP` runs before the task's output is stored, so rewrites propagate
-everywhere the output is used: downstream task context, callbacks, the final
-crew output, and the task's `output_file` on disk.
-</Note>
-
-### Guarding Flow Methods
-
-```python
-@on(InterceptionPoint.PRE_STEP)
-def guard_publish(ctx):
-    if ctx.kind == "flow_method" and ctx.step_name == "publish":
-        if not ctx.flow.state.get("reviewed"):
-            raise HookAborted(reason="publish requires review", source="review-gate")
-```
-
-### Filtering by Agent
-
-Step hooks support the same `agents=` filter as the other points (matched
-against the executing agent's role on task steps):
-
-```python
-@on(InterceptionPoint.POST_STEP, agents=["Researcher"])
-def log_research_steps(ctx):
-    print(f"research step done: {ctx.step_name}")
-```
-
-## Aborting a Step
-
-Raising `HookAborted` in `PRE_STEP` stops the step before any agent or method
-work happens, and the abort propagates out of the execution with its reason —
-it is not swallowed. Any other exception raised by a step hook is swallowed
-(fail-open), like at every other point.
-
-## Managing Hooks in Tests
-
-```python
-from crewai.hooks import clear_all_hooks
-
-clear_all_hooks()  # Clears every point, including steps
-```

 ## Overview
 
-Tool hooks are executed at two interception points:
+Tool hooks are executed at two critical points:
+- **Before Tool Call**: Modify inputs, validate parameters, or block execution
+- **After Tool Call**: Transform results, sanitize outputs, or log execution details
 
-| Point | When | Hook receives |
-|-------|------|---------------|
-| `PRE_TOOL_CALL` | Before every tool execution | `ToolCallHookContext` |
-| `POST_TOOL_CALL` | After every tool execution | `ToolCallHookContext` (with results set) |
+## Hook Types
 
-Write them with the [`@on` decorator](/edge/en/learn/execution-hooks). The
-[legacy `@before_tool_call` / `@after_tool_call` decorators](#legacy-decorators)
-keep working unchanged — both styles register on the same engine and run in one
-ordered chain.
+### Before Tool Call Hooks
 
-## Hook Signature
+Executed before every tool execution, these hooks can:
+- Inspect and modify tool inputs
+- Block tool execution based on conditions
+- Implement approval gates for dangerous operations
+- Validate parameters
+- Log tool invocations
 
+**Signature:**
 ```python
-from crewai.hooks import on, HookAborted, InterceptionPoint, ToolCallHookContext
-
-@on(InterceptionPoint.PRE_TOOL_CALL)
-def before_hook(ctx: ToolCallHookContext) -> None:
-    # Mutate ctx.tool_input in place, or
-    # raise HookAborted(reason, source) to block the call
-    ...
-
-@on(InterceptionPoint.POST_TOOL_CALL)
-def after_hook(ctx: ToolCallHookContext) -> str | None:
-    # Return a string to replace ctx.tool_result
-    # Return None to keep the original result
+def before_hook(context: ToolCallHookContext) -> bool | None:
+    # Return False to block execution
+    # Return True or None to allow execution
     ...
 ```
 
-Unlike the boundary and step points, the tool-call points pass the rich
-`ToolCallHookContext` directly as the hook argument (there is no separate
-`ctx.payload`): mutate `ctx.tool_input` in place before the call, and return a
-string to replace the result after it.
+### After Tool Call Hooks
 
-When a call is blocked, the tool does not run and the agent receives
-`"Tool execution blocked by hook. Tool: <name>"` as the result — the run
-continues. `POST_TOOL_CALL` hooks still fire on blocked calls, so monitoring
-hooks see every attempt.
+Executed after every tool execution, these hooks can:
+- Modify or sanitize tool results
+- Add metadata or formatting
+- Log execution results
+- Implement result validation
+- Transform output formats
+
+**Signature:**
+```python
+def after_hook(context: ToolCallHookContext) -> str | None:

+    # Return None to keep original result
+    ...

 ## Hook Management
 
+### Unregistering Hooks
+
 ```python
 from crewai.hooks import (
-    InterceptionPoint,
-    clear_all_hooks,
-    clear_hooks,
-    get_hooks,
-    unregister_hook,
+    unregister_before_tool_call_hook,
+    unregister_after_tool_call_hook
 )
 
-# Unregister a specific hook
-unregister_hook(InterceptionPoint.PRE_TOOL_CALL, my_hook)
+# Unregister specific hook
+def my_hook(context):
+    ...
 
-# Clear one point, or everything (e.g. between tests)
-clear_hooks(InterceptionPoint.POST_TOOL_CALL)
-clear_all_hooks()
-
-# Inspect what's registered
-print(len(get_hooks(InterceptionPoint.PRE_TOOL_CALL)))
+register_before_tool_call_hook(my_hook)
+# Later...
+success = unregister_before_tool_call_hook(my_hook)
+print(f"Unregistered: {success}")
 ```
 
-The legacy management API (`register_before_tool_call_hook`,
-`unregister_before_tool_call_hook`, `clear_before_tool_call_hooks`,
-`clear_all_tool_call_hooks`, `get_before_tool_call_hooks`, and their `after_`
-counterparts) operates on the same underlying registries, so either API can
-manage hooks registered by the other.
-
-## Legacy Decorators
-
-The original per-point decorators keep working unchanged and run in the same
-registration-order chain as `@on` hooks:
+### Clearing Hooks
 
 ```python
-from crewai.hooks import before_tool_call, after_tool_call
+from crewai.hooks import (
+    clear_before_tool_call_hooks,
+    clear_after_tool_call_hooks,
+    clear_all_tool_call_hooks
+)
 
+# Clear specific hook type
+count = clear_before_tool_call_hooks()
+print(f"Cleared {count} before hooks")
+
+# Clear all tool hooks
+before_count, after_count = clear_all_tool_call_hooks()
+print(f"Cleared {before_count} before and {after_count} after hooks")
+```
+
+### Listing Registered Hooks
+
+```python
+from crewai.hooks import (
+    get_before_tool_call_hooks,
+    get_after_tool_call_hooks
+)
+
+# Get current hooks
+before_hooks = get_before_tool_call_hooks()
+after_hooks = get_after_tool_call_hooks()
+
+print(f"Registered: {len(before_hooks)} before, {len(after_hooks)} after")
+```
+
+## Advanced Patterns
+
+### Conditional Hook Execution
+
+```python
 @before_tool_call
-def block_dangerous_tools(context):
-    if context.tool_name in ('delete_database', 'drop_table'):
-        return False  # Block execution
-    return None
+def conditional_blocking(context: ToolCallHookContext) -> bool | None:
+    # Only block for specific agents
+    if context.agent and context.agent.role == "junior_agent":
+        if context.tool_name in ['delete_file', 'send_email']:
+            print(f"❌ Junior agents cannot use {context.tool_name}")
+            return False
+
+    # Only block during specific tasks
+    if context.task and "sensitive" in context.task.description.lower():
+        if context.tool_name == 'web_search':
+            print("❌ Web search blocked for sensitive tasks")
+            return False
 
-@after_tool_call(tools=["web_search"])
-def sanitize_results(context):
-    if context.tool_result and "password" in context.tool_result.lower():
-        return context.tool_result.replace("password", "[REDACTED]")
     return None
 ```
 
-Differences from `@on`:
+### Context-Aware Input Modification
 
-- **Blocking** is `return False` from a before hook — equivalent to raising
-  `HookAborted`, but without a custom reason or source for telemetry. The agent
-  sees the same `"Tool execution blocked by hook"` message.
-- **Signatures** are point-specific: before hooks return `bool | None`, after
-  hooks return `str | None`. The context object is the same
-  `ToolCallHookContext`.
-- **Filters and crew-scoping** work the same way:
-  `@before_tool_call(tools=[...], agents=[...])`, and applying the decorator to
-  a `@CrewBase` method scopes it to that crew.
+```python
+@before_tool_call
+def enhance_tool_inputs(context: ToolCallHookContext) -> None:
+    # Add context based on agent role
+    if context.agent and context.agent.role == "researcher":
+        if context.tool_name == 'web_search':
+            # Add domain restrictions for researchers
+            context.tool_input['domains'] = ['edu', 'gov', 'org']
 
-Prefer `@on` for new code; keep the legacy style where it is already in use —
-there is no behavioral penalty.
+    # Add context based on task
+    if context.task and "urgent" in context.task.description.lower():
+        if context.tool_name == 'send_email':
+            context.tool_input['priority'] = 'high'
+
+    return None
+```
+
+### Tool Chain Monitoring
+
+```python
+tool_call_chain = []
+
+@before_tool_call
+def track_tool_chain(context: ToolCallHookContext) -> None:
+    tool_call_chain.append({
+        'tool': context.tool_name,
+        'timestamp': time.time(),
+        'agent': context.agent.role if context.agent else 'Unknown'
+    })
+
+    # Detect potential infinite loops
+    recent_calls = tool_call_chain[-5:]
+    if len(recent_calls) == 5 and all(c['tool'] == context.tool_name for c in recent_calls):
+        print(f"⚠️  Warning: {context.tool_name} called 5 times in a row")
+
+    return None
+```
 
 ## Best Practices
 
-1. **Keep hooks focused and fast** — they run on every tool call
-2. **Modify in-place** — always mutate `ctx.tool_input`, never replace the dict
-3. **Prefer filters over conditionals** — `tools=` / `agents=` keep hook bodies small
-4. **Abort loudly** — raise `HookAborted` with a meaningful reason and source;
-   any other exception is swallowed (fail-open)
-5. **Use type hints** — annotate with `ToolCallHookContext` for IDE support
-6. **Clear hooks in tests** — call `clear_all_hooks()` between test runs
+1. **Keep Hooks Focused**: Each hook should have a single responsibility
+2. **Avoid Heavy Computation**: Hooks execute on every tool call
+3. **Handle Errors Gracefully**: Use try-except to prevent hook failures
+4. **Use Type Hints**: Leverage `ToolCallHookContext` for better IDE support
+5. **Document Blocking Conditions**: Make it clear when/why tools are blocked
+6. **Test Hooks Independently**: Unit test hooks before using in production
+7. **Clear Hooks in Tests**: Use `clear_all_tool_call_hooks()` between test runs
+8. **Modify In-Place**: Always modify `context.tool_input` in-place, never replace
+9. **Log Important Decisions**: Especially when blocking tool execution
+10. **Consider Performance**: Cache expensive validations when possible
+
+## Error Handling
+
+```python
+@before_tool_call
+def safe_validation(context: ToolCallHookContext) -> bool | None:
+    try:
+        # Your validation logic
+        if not validate_input(context.tool_input):
+            return False
+    except Exception as e:
+        print(f"⚠️ Hook error: {e}")
+        # Decide: allow or block on error
+        return None  # Allow execution despite error
+```
+
+## Type Safety
+
+```python
+from crewai.hooks import ToolCallHookContext, BeforeToolCallHookType, AfterToolCallHookType
+
+# Explicit type annotations
+def my_before_hook(context: ToolCallHookContext) -> bool | None:
+    return None
+
+def my_after_hook(context: ToolCallHookContext) -> str | None:
+    return None
+
+# Type-safe registration
+register_before_tool_call_hook(my_before_hook)
+register_after_tool_call_hook(my_after_hook)
+```
+
+## Integration with Existing Tools
+
+### Wrapping Existing Validation
+
+```python
+def existing_validator(tool_name: str, inputs: dict) -> bool:
+    """Your existing validation function."""
+    # Your validation logic
+    return True
+
+@before_tool_call
+def integrate_validator(context: ToolCallHookContext) -> bool | None:
+    if not existing_validator(context.tool_name, context.tool_input):
+        print(f"❌ Validation failed for {context.tool_name}")
+        return False
+    return None
+```
+
+### Logging to External Systems
+
+```python
+import logging
+
+logger = logging.getLogger(__name__)
+
+@before_tool_call
+def log_to_external_system(context: ToolCallHookContext) -> None:
+    logger.info(f"Tool call: {context.tool_name}", extra={
+        'tool_name': context.tool_name,
+        'tool_input': context.tool_input,
+        'agent': context.agent.role if context.agent else None
+    })
+    return None
+```
 
 ## Troubleshooting
 
 ### Hook Not Executing
-- Verify the hook is registered before crew execution
-- Check whether an earlier hook blocked the call (subsequent pre hooks don't run)
-- Check `tools=` / `agents=` filters against the actual tool name and agent role
+- Verify hook is registered before crew execution
+- Check if previous hook returned `False` (blocks execution and subsequent hooks)
+- Ensure hook signature matches expected type
 
 ### Input Modifications Not Working
-- Use in-place modifications: `ctx.tool_input['key'] = value`
-- Don't replace the dict: `ctx.tool_input = {}`
+- Use in-place modifications: `context.tool_input['key'] = value`
+- Don't replace the dict: `context.tool_input = {}`
 
 ### Result Modifications Not Working
-- Return the modified string from a `POST_TOOL_CALL` hook
+- Return the modified string from after hooks
 - Returning `None` keeps the original result
+- Ensure the tool actually returned a result
 
 ### Tool Blocked Unexpectedly
-- Check all pre hooks for `HookAborted` / `return False` conditions
-- The abort reason and source appear on the `HookDispatchedEvent` telemetry
+- Check all before hooks for blocking conditions
+- Verify hook execution order
+- Add debug logging to identify which hook is blocking

-- ``dispatch`` has a no-op fast path (a single dict lookup) when no hooks are
-  registered for a point.
-- Hooks are synchronous. They may be invoked from async seams, so they must not
-  block on heavy I/O (same restriction as the legacy hooks).
-- ``HookAborted`` propagates by design. Any other exception raised by a hook is
