* 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
* fix: enforce owner-only permissions on credential files
Credentials stored at rest were left world-readable on multi-user hosts:
- TokenManager._get_secure_storage_path() documented its credential dir as
mode 0o700 but created it via mkdir() with default perms (0o755), leaving
the Fernet secret.key and encrypted tokens.enc in a traversable dir.
- Settings.dump() persisted tool_repository_password (plaintext) to
settings.json via open("w"), producing a 0o644 file, and created the
config dir at 0o755 — despite the sibling token_manager already writing
secrets atomically at 0o600.
Fixes:
- TokenManager: chmod the credential dir to 0o700 after mkdir (robust against
umask and pre-existing dirs).
- Settings: write settings.json atomically at 0o600 (mkstemp + chmod +
os.replace) and chmod the dedicated config dir to 0o700. The /tmp and cwd
fallback parents are deliberately not chmod'd; the 0o600 file mode protects
the credential there.
Adds regression tests asserting 0o600 files and 0o700 dirs, and that shared
fallback dirs are not globally tightened.

`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"}.
The page itself already landed on main via #6247. This rebases onto main
and applies the two remaining changes:
- Nest crew-studio + merged-step-card into a collapsible "Crew Studio"
nav group (pencil icon), across edge and v1.14.7 in en, pt-BR, ko, ar.
- Remove the temporary "Rolling out" Note banner (feature ships today).

* 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)
Document the merge of the task and agent nodes into a single step card on
the Studio canvas. Written as evergreen present-tense feature docs with a
dated rollout banner (June 24th) for the pre-launch customer announcement;
the banner is the only time-bound content and is flagged for removal after
ship. Added in edge + v1.14.7 across en, pt-BR, ko, and ar, with nav entries
in docs.json and three canvas/editor/swap screenshots.

* 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
Adds a consolidated `datadog.mdx` under `docs/edge/{en,pt-BR,ko,ar}/enterprise/guides/`
covering both the Datadog Agent path (stdout JSON logs via `CREWAI_LOG_FORMAT=json`)
and the Datadog OTLP intake, with a JSON log schema reference and a ready-to-import
operations dashboard (`datadog_dashboard.json`). Reframes `capture_telemetry_logs.mdx`
to lead with OpenTelemetry as the vendor-neutral path and point readers to the new
Datadog page for that ecosystem's setup.
* 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.
* Improve missing CrewAI install guidance
* fix: address pr review feedback
* fix: avoid mismatched memory save rows
* fix: wait for queued memory save events
* fix: avoid matching memory saves on missing ids
* chore: normalize prerelease version to 1.14.8a1
