- Anchor the pre-baked-composite check to the actual three-line block
shape instead of a naive substring match, so authored prose that
merely mentions "Tool Description:" is never truncated (CodeRabbit /
Bugbot review finding). Shared as
strip_composite_description_prefix() and reused by the function-
calling schema builder, which had the same naive split.
- Make render_text_description_and_args tolerate duck-typed tools
without a real formatted_description string (fixes CI: step-executor
tests pass Mock tools whose auto-created attribute is not a str).

BaseTool.model_post_init silently replaced the public description field
with the LLM-facing composite ("Tool Name: ...\nTool Arguments: ...\n
Tool Description: <authored>"), breaking equality assertions on authored
text and hiding the extra prompt tokens from token-careful authors.
The authored description now survives construction as written. The
composite is composed on demand via a new formatted_description property
on BaseTool and CrewStructuredTool (shared format_description_for_llm
helper), and every prompt path that relied on the baked-in composite —
render_text_description_and_args, ToolUsage._render, and tool-usage
error messages — now renders through it, so the text the LLM sees is
unchanged.
The helper strips any pre-existing composite block before composing, so
tools deserialized from old checkpoints and adapters that still bake the
composite into the field (e.g. the crewai-tools MCP adapter) don't get
double-wrapped. BaseTool._generate_description remains as a no-op hook
because subclasses override it and model_post_init still calls it.
Fixes EPD-179.

* Support legacy OpenAI base URL env var
* Add custom OpenAI-compatible endpoint support
* Refactor OpenAI completion module test to restore original module state
- Added logic to save and restore the original OpenAI completion module during the test to prevent issues with class re-imports affecting subsequent tests.
- Ensured that the test checks for the presence of the module and its attributes only after the module is properly reloaded.
- Improved test reliability by avoiding potential failures due to module state changes across tests.
* addressing comments
* fix: drain memory writes before kickoff and flow completion events
Background memory saves from the final task could still be in flight
when `CrewKickoffCompletedEvent`/`FlowFinishedEvent` fired, so telemetry
listeners tore down before `MemorySaveCompletedEvent` arrived and the
save span surfaced as "Span orphaned" errors in traces despite the
record persisting. `Crew` now drains all pending saves — including
per-agent `agent.memory` pools, which the old `finally`-only drain
missed entirely — before emitting the completion event, with the same
ordering applied to both `FlowFinishedEvent` emit paths in the flow
runtime.
* fix: address review findings on the memory drain paths
Bugbot and CodeRabbit flagged gaps in the drain coverage: the
hierarchical `manager_agent` memory pool was never drained,
`Crew.akickoff` lacked the exception-path safety net that sync
`kickoff` has, and `finalize_session_traces` emitted the deferred
session-end `FlowFinishedEvent` without draining first. Also offloads
the pre-emit drains in the flow runtime to `asyncio.to_thread` so the
blocking wait doesn't stall other coroutines sharing the event loop.
* fix: flush event bus after memory drain in flow completion paths
Bugbot flagged that flow paths went straight from the memory drain to
`FlowFinishedEvent`, while crew kickoff flushes the bus in between.
Save completion events emitted during the drain could still have
pending async handlers when flow-finished triggered trace teardown.
Adds a `crewai_event_bus.flush()` after the drain at both flow runtime
emit sites and in `finalize_session_traces`, mirroring
`Crew._create_crew_output`.
* fix(cli): unify `crewai run` flow input resolution; prompt from state schema
`crewai run` resolved the configured [tool.crewai] flow, but `--inputs` was
hard-gated behind `--definition` and routed through a separate branch — the two
ways of pointing at the same flow didn't share resolution, and required inputs
were never detected, prompted, or validated (a missing field only blew up at
runtime).
Now inputs and definition come from one place:
- Remove the "--inputs requires --definition" gate (cli.py, run_crew.py,
run_declarative_flow.py). `--inputs` alone resolves the configured flow,
exactly like a bare `crewai run`; `--definition` is purely an override. The
project-env re-exec forwards `--inputs` instead of rejecting it.
- Read the flow's state schema from the runtime Flow instance
(`type(flow.state).model_json_schema()`), which is reliable for both inline
`json_schema` and ref-imported `pydantic` state (the static definition's
json_schema is None for the common ref case).
- Plain `crewai run` detects required state fields (minus those satisfied by
state defaults) and prompts for them interactively, showing each field's
description; skipped in non-interactive / CREWAI_DMN mode.
- Validate against the schema before kickoff: pointed
"Missing required input 'x' — <description>" errors, and warn on unknown keys
with a did-you-mean suggestion (catches typos like `prospect_emai`).
`--inputs` on a non-flow project now errors clearly ("only supported for
declarative flows") instead of the old confusing gate.
Tests: schema-driven prompt/validate/override paths, unknown-key warning,
defaults-satisfy-required, type validation, and re-exec input forwarding.

* fix(cli): forward reserved `id` input to flow kickoff; ruff format
- Cursor: the schema filter treated an `id` key in --inputs as unknown and
dropped it, regressing kickoff's persistence-restore support (inputs["id"]).
Let `id` pass through untouched (test: reserved_id_input_is_forwarded).

`ruff format --check` step).

* fix(cli): don't block persistence-restore resume on schema validation
Cursor (High): `crewai run --inputs '{"id":"…"}'` is a persistence resume —
kickoff hydrates full state from storage, so schema-required fields may come
from the restored state rather than --inputs. The new required-field
prompt/validation was erroring/prompting before kickoff, breaking resume. When
`id` is present in --inputs, forward the inputs unchanged and skip the
prompt/validation. Test: test_id_only_input_skips_required_validation.

* fix(cli): load project .env in the declarative-flow runner
The declarative-flow path never loaded .env — flow projects (type = "flow")
missed API keys/config that crew projects pick up. The JSON-crew path loads
Path.cwd()/.env with override=True (run_crew._run_json_crew); mirror that at
the top of run_declarative_flow() so flow projects behave the same regardless
of where crewai is installed. Test: run_declarative_flow_loads_project_env.

* feat(cli): unify runtime-input prompting across declarative flows and crews
Declarative (JSON) crews now resolve inputs the same way declarative flows
do, via a shared crewai_cli.input_prompt module (prompt_for_inputs,
parse_inputs_json, closest_name, is_interactive):
- accept --inputs (previously rejected for crews), forwarded to the crew
subprocess via CREWAI_JSON_CREW_INPUTS and validated before spinning up uv
- layer --inputs over the crew's declared `inputs` defaults
- prompt for missing {placeholder}s with the same UX as flows, and error
cleanly with a pointed per-name message when non-interactive
- warn on unknown keys with a "did you mean" suggestion
Unlike flows — whose state schema is authoritative, so unknown keys are
dropped — the crew placeholder scan is heuristic (agent/task text fields
only), so unrecognized keys are warned about but kept, to avoid discarding a
value a field the scan doesn't cover may rely on.
--inputs remains rejected for classic (Python/YAML) crews, which take their
inputs from main.py. run_declarative_flow's private input helpers move to the
shared module with no behavior change.

* test(crewai): update mirrored CLI test after run_crew input refactor
lib/crewai/tests/cli/test_run_crew.py imports crewai_cli internals and is
collected by the lib/crewai test job (Run Tests). It still imported
_prompt_for_missing_inputs, which was replaced by _resolve_crew_inputs, so
the module failed to import — erroring pytest at collection and cancelling
the rest of the matrix via fail-fast.
Point it at _resolve_crew_inputs and patch the prompt in the shared
crewai_cli.input_prompt module where prompting now lives.

* fix(cli): filter unknown --inputs keys even on flow persistence restore
Review follow-up: the `id` (persistence-restore) branch of
_resolve_flow_inputs returned the raw payload, so typo keys passed alongside
`id` skipped the unknown-key warning/drop and reached kickoff — which can
fail strict (extra="forbid") flow state models. The restore path now still
warns on and drops unknown keys (keeping `id` and known state fields); it
only skips the required-field prompt and pre-kickoff validation, which
persistence hydrates. Regression test: test_id_restore_still_drops_unknown_keys.
Also drop the duplicate module import in test_input_prompt.py (both `import`
and `from ... import` of crewai_cli.input_prompt) flagged by the code-quality
bot; monkeypatching now uses the string target form.

Inline agent and crew actions can now use repository-backed agents
without duplicating role, goal, and backstory in each definition.
Examples:
* `agent.with.from_repository: support_specialist`
* `crew.with.agents.researcher.from_repository: researcher`
`PlusAPI.get_agent` now uses the shared synchronous request path so
project loaders can fetch repository agents without nested event loops.
Flow action inputs now support `${...}` inside strings, not only
strings that are fully wrapped in one expression. This lets authored
flows use simple prompt-like values such as:
* `query: "News about ${state.topic}"`
* `input: "Ticket ${text(state, "ticket.id", "unknown")}"`
* `sources: ["${state.primary_source}", "archive-${state.topic}"]`
Whole-expression values still preserve their runtime type, so
`${state.limit}` remains a number and `${state.domains}` remains a list.
Mixed literal and expression strings render as text.
This removes the need to build labeled strings with CEL concatenation,
which was hard to read, easy to quote incorrectly in YAML, and a poor
fit for the Flow authoring skill examples.
### Overview
`BedrockCompletion.acall()` (the async completion path used when a crew is kicked off asynchronously) requires `aiobotocore` to build its async client. The `bedrock` extra, however, only declared `boto3`. Crews configured with an AWS Bedrock model work fine under a synchronous `kickoff()`, since that path only needs `boto3`, but raise `NotImplementedError: Async support for AWS Bedrock requires aiobotocore` as soon as they're kicked off asynchronously, since `aiobotocore` was never installed.
The fix adds `aiobotocore` to the `bedrock` extra, so `crewai[bedrock]` installs both the sync (`boto3`) and async (`aiobotocore`) dependencies the native Bedrock provider needs. The lockfile is regenerated to match. The exception message is also corrected — it previously pointed to a `bedrock-async` extra that never existed in `pyproject.toml`.
### Changes
- `lib/crewai/pyproject.toml`: add `aiobotocore~=3.5.0` to the `bedrock` extra
- `uv.lock`: regenerated to reflect the updated `bedrock` extra
- `lib/crewai/src/crewai/llms/providers/bedrock/completion.py`: fix the install hint in the `NotImplementedError` message to reference the real `bedrock` extra instead of the nonexistent `bedrock-async`
* Document flow agent options
Document and type inline Flow agent options so authored flows can set:
* `llm.model`, `llm.max_tokens`, and `llm.max_completion_tokens`
* `planning_config.max_attempts`
* `allow_delegation`
* `max_iter`
* `max_rpm`
* `max_execution_time` in seconds
Also tell the flow skill to omit optional fields unless needed.
* Potential fix for pull request finding 'Unused import'

A method that listens to its own name can re-trigger itself or collide
with router events. Rejecting that definition keeps declarative and
Python-authored flows aligned before kickoff.
CEL string concatenation currently fails when prompt builders read
missing or null fields. This commit adds `text(root, "path", "default")`
custom CEL helper so prompt text can safely read nested state/output
values.
Point `crewai template list`/`template add` at the crewAIInc-fde GitHub
org so the FDE template_* repos are listed and installed instead of the
crewAIInc ones.

* Support inline skill definitions
This commit adds inline skill loading without a need for a file. It also
DRYs the skill loading feature.
* Address code review suggestions
* Type tool and app in CrewDefinition
This commit fixes a bug in the CrewDefinition class where the tool and
app were not being added.
* Type mcps= parameter
* Add generated Flow Definition authoring skill
Generate a portable skill from the Flow Definition schema so agents can
author valid declarative flows with the same reference CrewAI uses to
validate them. New declarative flow projects now write this skill.
```python
from crewai.flow.flow_definition import FlowDefinition
skill = FlowDefinition.skill(skips=(), examples_format="yaml")
```
* `examples_format` accepts `"yaml"` or `"json"`.
* Supported skips: `conversational`, `non_linear_flows`, `each`, `hitl`, `persistence`, `config`, `expression_action`, `script_action`, `tool_action`
The generated skill includes authoring rules, a routed crew example, and
an API reference extracted from the Flow, action, state, agent, crew,
and task Pydantic schemas.
* Fix declarative flow scaffold without framework import
* Fix skipped expression action guidance
* Fix markdown links in skill
* Require explicit CrewAI project definitions
JSON crews and declarative flows now resolve from `[tool.crewai]`
metadata instead of implicit filename discovery. This makes project type
selection deterministic, prevents stray `crew.json(c)` files from changing
CLI behavior, and centralizes definition path validation for run, install,
deploy validation, plotting, and memory reset paths.
`[tool.crewai].definition` must be a project-local file path. Absolute
paths, `~`, missing files, directories, and paths escaping the project root
are rejected so deploy and runtime commands use the same contract.
Breaking changes and migration paths:
* JSON crew projects are no longer discovered from `crew.json` or
`crew.jsonc` alone. Add explicit metadata:
```toml
[tool.crewai]
type = "crew"
definition = "crew.jsonc"
```
* Declarative flow projects must use a valid project-local definition path:
```toml
[tool.crewai]
type = "flow"
definition = "flows/research.yaml"
```
* `Flow.from_definition(definition)` is removed. Use:
```python
Flow.from_declaration(contents=definition)
```
* `FlowDefinition.to_json()` and `FlowDefinition.to_yaml()` are removed.
Use `FlowDefinition.to_dict()` and serialize with the caller's JSON or
YAML library.
* `FlowDefinition.from_dict()` is removed. Use:
```python
FlowDefinition.from_declaration(contents=data)
```
* `FlowDefinition.json_schema()` is removed. Use Pydantic's schema API only
where schema generation is intentionally needed:
```python
FlowDefinition.model_json_schema(by_alias=True)
```
* `crewai_cli.run_crew.find_crew_json_file()` and `_has_json_crew()` are
removed. Use `configured_project_json_crew()` or the shared
`crewai_core.project.configured_project_definition("crew")` helper.
* `crewai reset-memories` now only loads JSON crews declared through
`[tool.crewai].definition`, and invalid declared JSON crew definitions
fail instead of silently falling back to classic crew discovery.
* Address code review comments
* Track conversational flow turn usage in telemetry
* adjusted name to flow:conversation_turn
* only mark on turn completed event
* ensure tui also emits these events
`StateProxy` looked like a thread-safety boundary, but it only protected
a small slice of state operations. Some examples of operations that were
not covered:
- `self.state.counter += 1`, `self.state["counter"] += 1` (increments)
- `self.state.user.profile.score += 1` (nested object mutations)
- `self.state.config["limits"]["max"] = 10` (mutation through model fields)
- `self.state.items[0].status = "done"` (list/container mutations)
This commit decided to remove it completely for simplicity and
performance:
- Simpler runtime code
- attr read: 24x faster, attr write: 27x faster, list append: 19x faster (local benchmark)
- Clearer concurrency contract (lifecycle locks remain, but arbitrary
shared state mutation is not presented as thread-safe)
Declarative flows already used `module:qualname` refs for runtime
objects, but crew JSON tools still had their own lookup path. That meant
examples like `project_tools:LookupTool` were treated as named
`crewai_tools` lookups and failed with guidance that only mentioned
`SerperDevTool` or `custom:<name>`. Invalid refs such as
`not_tools:NotATool` also missed the same BaseTool validation used by
flow tool actions.
Move ref resolution into a shared declarative helper, use it from flow
tool actions and crew JSON loading, and require tool refs to resolve to
`BaseTool` classes before instantiation. Validation still checks tool
refs structurally, so validating a crew does not import or execute
project code.
Allow required JSON schema state fields to be supplied by kickoff inputs
instead of requiring every field to exist in state.default before
runtime.
Example: a flow with required lead_name and no state.default can now run
with kickoff inputs={"lead_name": "Ada Lovelace"}.
* Fix symlink path traversal in skill archive extraction
`_safe_extractall` (the Python < 3.12 fallback used by `crewai skills`
archive unpacking) validated each member's *name* against the destination
but never validated symlink/hardlink *targets*. A malicious skill tarball
could plant a symlink escaping the destination (e.g. `link -> /home/user/.ssh`)
followed by a regular member written through it (`link/authorized_keys`),
escaping `dest` even though every member name resolves inside it — the
classic symlink-extraction traversal.
The 3.12+ path (`extractall(..., filter="data")`) already blocks this; the
fallback now mirrors it by rejecting absolute link targets and any link
target that resolves outside the destination directory.
Adds regression tests covering absolute and relative escaping symlinks plus
benign in-tree symlinks and ordinary archives.

Add a single declaration loader shared by API and CLI callers.
- Add FlowDefinition.from_declaration for FlowDefinition instances, dictionaries, YAML/JSON strings, and file paths
- Add Flow.from_declaration to build runnable flows directly from the same inputs
- Route declarative flow CLI loading through Flow.from_declaration so path handling and validation stay centralized
```
# Load just the serializable definition when you do not need to run it yet.
definition = FlowDefinition.from_declaration(path="flows/research.crewai")
definition = FlowDefinition.from_declaration(contents=flow_yaml)
definition = FlowDefinition.from_declaration(contents=flow_dict)
# Build a runnable flow directly from the same declaration inputs.
flow = Flow.from_declaration(path="flows/research.crewai")
flow = Flow.from_declaration(contents=flow_yaml)
flow = Flow.from_declaration(contents=flow_dict)
flow = Flow.from_declaration(contents=definition)
# Run it like any other flow.
result = flow.kickoff(inputs={"topic": "AI agents"})
# The CLI now goes through the same path-based loader.
# crewai run --definition flows/research.crewai
```
The previous `~=1.34.0` pin kept us on the unmaintained 1.34 line —
last patched as `1.34.1` in June 2025, eight minor releases behind
upstream — and caused `_create_exp_backoff_generator` `ImportError`
crashes in factory deployments where the OpenTelemetry Operator's
injected init container shadows
`opentelemetry.exporter.otlp.proto.common._internal` with >=1.35 while
our `opentelemetry-exporter-otlp-proto-grpc==1.34.1` still imports the
removed private symbol. Pinning to `~=1.42.0` tracks the current
upstream stable line; the resolver now lands on 1.42.1 and our public
OTel trace API usage is unaffected.
Remove redundant startup logs from `crewai run` and make the legacy flow
command warning actionable.
- Stop printing `Running the Flow` and `Running the Crew` before project
execution.
- Stop printing the redundant `Flow started with ID: ...` line while
preserving flow lifecycle event emission.
- Replace Click's generic `kickoff` deprecation warning with a clearer
message that tells users to use `crewai run`.
Inline crews default to `verbose=False`. They set the shared formatter's
`verbose` value in `lib/crewai/src/crewai/crew.py`, which could hide
flow method status from `lib/crewai/src/crewai/events/utils/
console_formatter.py`.
Remove that `verbose` check for flow method status. Flow output is still
controlled by `suppress_flow_events`.
Normal quiet crews are unchanged because crew, task, and agent logs
still use their own `verbose` checks.
* Add declarative Flow CLI support
Currently, declarative flows can be loaded by the runtime, but the CLI
still treats them as an experimental definition file instead of a
first-class Flow project shape.
With this PR, `crewai create flow --declarative` scaffolds a YAML-backed
Flow project, and `crewai run`, `crewai flow kickoff`, and `crewai flow
plot` can run against the configured definition.
This also lets crew actions reference reusable crew definition files or
folders and override their inputs from the Flow definition, so
declarative flows can compose existing declarative crews without
inlining everything.
* Address code review comments
This commit fixes a bug where a router method could not be the start
method of a flow.
This is useful when you want to route against the initial state, or even
stack two routers.
Currently, tools have a strong input contract through `args_schema`, but no
output contract. This means that anything a tool outputs is converted to
string.
Not only the contract is weak, but the "invisible" conversion to string can
have unexpected effects when the tool returns complex objects like dicts and
arrays.
With this PR, a tool can _optionally_ define an output contract with
`output_schema`. CrewAI validates the raw result and sends the agent JSON.
```python
class ProductResult(BaseModel):
sku: str
name: str
in_stock: bool
class ProductLookupTool(BaseTool):
name: str = "Product Lookup"
description: str = "Look up product availability by SKU."
def _run(self, sku: str) -> ProductResult:
return ProductResult(sku=sku, name="USB-C dock", in_stock=True)
```
If the result does not match the schema, CrewAI warns and falls back to
`str(raw_result)` instead of failing the run:
```python
@tool("Product Lookup", output_schema=ProductResult)
def product_lookup(sku: str) -> dict[str, object]:
return {"sku": sku, "name": "USB-C dock", "in_stock": True}
#=> RuntimeWarning: Failed to validate or serialize output from tool 'Bad Product Lookup' using output_schema 'ProductResult'... Falling back to str(raw_result).
```
This is additive and non-breaking. Existing tools do not need to change. Tools
without `output_schema` keep the old string behavior. Invalid typed outputs
warn and fall back to the old formatting path.
* docs: add "One Card per Step" Studio page (AGE-107)

* Add single agent action to Flow definitions
Lets a flow method build and run a single CrewAI agent directly, without
wrapping it in a crew. Same idea as the existing `crew` action, but for
one agent.
methods:
answer:
do:
call: agent
with:
role: Analyst
goal: Answer questions
backstory: Knows things.
input: "${state.question}"
start: true
* `input` is required and interpolated from flow state, like
`${state.question}` or `${item}` inside an `each` loop
* optional `response_format` points at a Pydantic model (`{"python":
"models.AnswerModel"}`) to get structured output
* `input` must be a string and its CEL is validated at load time, so bad
expressions like `${state.}` fail early
* Simplify test code
* Validate flow CEL expressions at definition load time
Promote CEL expression handling to a public Expression API and validate expressions when a FlowDefinition is built instead of when it executes.
Invalid CEL syntax or unknown roots now raise ValidationError from FlowDefinition.from_yaml() and FlowDefinition.from_dict(). Expressions may reference state and outputs, plus item inside each.do; bare identifiers are rejected as unknown roots.
For with values, the CEL contract is intentionally simple: after trimming whitespace, a string is evaluated as CEL only if it starts with ${ and ends with }. Anything else is treated as a literal value, so partial interpolation is not supported. If the content inside the wrapper is not valid CEL, validation fails.
Examples:
```text
"${state.topic}" -> evaluated, returns state.topic
"topic is ${state.topic}" -> literal string
"${state.topic} suffix" -> literal string
"${'a'}${'b'}" -> invalid CEL
```
* Honor explicit empty-context overrides in evaluate() / render_template()
* Use explicit name/action shape for each.do steps
* Add optional `if` expression to `each.do` steps
Lets a step inside an `each` action run conditionally based on a CEL
expression evaluated against `item` and prior step `outputs`.
* feat: update pyproject.toml to specify wheel targets
Added a new section to the pyproject.toml file to include only specific files in the wheel build, enhancing the packaging process. Updated tests to verify the inclusion of these targets.
* feat: add memory save event handling to activity log
Implemented event handlers for MemorySaveStartedEvent, MemorySaveCompletedEvent, and MemorySaveFailedEvent in the crew_run_tui module. This allows the application to log memory save operations, capturing their status and details in the activity log. Added corresponding tests to verify the correct logging behavior for successful and failed memory saves.
* feat: enhance memory save event handling in activity log
Added functionality to suppress nested memory save events and updated the handling of MemorySaveStartedEvent, MemorySaveCompletedEvent, and MemorySaveFailedEvent to improve logging accuracy. Introduced new tests to verify the correct behavior of memory save events, including scenarios for nested events and completion updates for timed-out entries.
* Fix memory save activity log handling
* Normalize alpha package versions
* Update scaffolded crew dependency
* feat: add button to copy setup instructions for CrewAI coding agents
Introduced a button in the documentation that allows users to easily copy setup instructions for CrewAI coding agents. The instructions include installation steps, environment setup, and best practices for using the CrewAI CLI. This enhancement aims to streamline the onboarding process for new users.
