Review follow-up: the STEPS panel and header are driven by flow method events
(FlowStarted / MethodExecution*), but the declarative runtime skips emitting
those when the flow declared config.suppress_flow_events. Interactive TUI runs
would then keep STEPS on "waiting…" and the header on "Starting flow…" while
nested crews still execute.
_run_declarative_flow_tui now forces flow.suppress_flow_events = False for the
interactive run (mirroring how the conversational path mutates the flow for the
TUI). The headless/terminal path never reaches this and keeps the flow's
declared setting. Regression test: test_run_declarative_flow_tui_enables_flow_events.

Declarative flows now run on the CrewRunApp TUI when interactive, matching
declarative crews and conversational flows. Headless contexts — CREWAI_DMN
(deploy), piped output, CI, any non-TTY — fall back to the direct-terminal
kickoff, gated by is_interactive() (folds in the CREWAI_DMN check and requires
a real TTY).
The TUI shows per-method progress: a new STEPS panel driven by flow method
events (FlowStarted / MethodExecutionStarted/Finished/Failed), each labeled
with its declarative call type (crew/agent/expression/…) read from the flow
definition. Crews/agents inside a method keep streaming in the main panel via
the existing crew/task/LLM handlers.
- crew_run_tui.py: _run_flow_worker (flow.kickoff in a thread worker; reuses
_on_crew_done/_on_crew_failed + _stringify_output), _is_flow_run gate so crew
rendering is byte-identical, flow-event subscriptions building _flow_steps,
and the STEPS sidebar + flow-aware header.
- run_declarative_flow.py: is_interactive() branch → _run_declarative_flow_tui
(EventListener, method-type map from flow._definition, crew-parity exit codes
and deploy chaining) or the existing terminal path.
Deviation from the approved plan: gate on is_interactive() rather than
is_dmn_mode_enabled() alone, so non-TTY runs (CI/pipes/CliRunner) never launch
a TUI — this also keeps existing headless flow tests green.

* 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).
- Apply ruff format to run_declarative_flow.py (fixes the lint-run
`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.

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
```
* 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
