Fixes #8123

Summary

Adds native async execution to JevDecisionTool using AsyncTypeSafeClient, available through await tool.arun(...). The async method awaits the SDK and shares request construction and response formatting with the synchronous method to preserve the structured result.

Injected async clients remain caller-owned. Clients created by the tool are closed after each call, including on SDK failure or cancellation. Cancellation propagates to the caller, and SDK configuration and retry behavior remain unchanged.

The README and missing-dependency messages use uv add typesafe-sdk. Tool helpers and behavior tests include concise docstrings.

Verification

• Tests added or updated for the changed behavior
• Relevant tests and quality checks pass locally

On Python 3.12:

• All 15 Jev tests pass after the installation-guidance and docstring update, including 7 new async cases for request construction, result parity, explicit SDK failures, cancellation, and client ownership. They use fake clients and require no credentials or paid API calls.
• After rebasing onto main at 65cdd70ac, the Jev, base-tool, structured-tool, and core MCP suites passed together: 176 tests passed.
• Local AST check: all 25/25 functions in the changed Python files have docstrings.
• A standalone check with real typesafe-sdk==0.7.2 and mocked HTTP verified both sync and async requests: model=None preserves the injected client default, and an explicit model override is honored. All four requests were intercepted locally; no API calls were made.
• Repository commit hooks passed for the feature commits. After the rebase, all pre-push checks passed with none bypassed: Ruff lint, formatting, mypy, lockfile validation, pip-audit, and branch naming.

Regression command, using the configured virtual environment:

python -m pytest lib/crewai-tools/tests/tools/jev_decision_tool_test.py lib/crewai/tests/tools/test_base_tool.py lib/crewai/tests/tools/test_structured_tool.py lib/crewai/tests/mcp -n 0 -q

An earlier additional run of lib/crewai-tools/tests/adapters/mcp_adapter_test.py could not complete locally: its spawned uv run python server selected an incompatible system interpreter and timed out. That optional integration run was interrupted and is not included in the 176 passing tests.

Additional context

Depends on #8076, which implements the synchronous Jev tool for #8066. This branch includes KET ⚡ (@ketpatil77)'s prerequisite commits, based on that PR's head 86f28b9e89f2bae95940699ca6d8f1eb99dc7d9d, rebased onto current main. Until #8076 merges, the diff also includes that author's synchronous implementation, exports, optional dependency, README, and tests.

The async implementation and tests are isolated in commit e72189ef2; commit 3d4a8bf5a corrects Jev export ordering for Ruff, and 937c1988f updates installation guidance and docstrings. The branch is rebased onto main at 65cdd70ac, including the dependency security fixes from #8221 and #8288. It inherits aiohttp==3.14.5 and yarl==1.25.1 from upstream, addressing the CI audit failure for aiohttp==3.14.3; no separate dependency upgrade is added here. The branch will need updating after #8076 merges to isolate the final diff.

KET ⚡ (@ketpatil77), this adds a separate async_client argument while retaining the existing synchronous API. Please flag any planned interface changes in #8076 that this async work should follow.

Note

Medium Risk
Adds a new optional third-party API tool gated on TYPESAFE_API_KEY, but behavior is isolated, errors are structured, and tests mock the SDK without live calls.

Overview
Introduces JevDecisionTool so crews can run a single TypeSafe Jev Choice question against task state and get back a structured result: selected label, probabilities, confidence, and optional model/usage metadata. It is exported from crewai_tools, documented in a new README, and wired as an optional typesafe-sdk extra (lockfile updated for that SDK and its HTTP stack).

The tool validates inputs (non-empty question, at least two choice labels), calls system_one via sync or await tool.arun(...) paths, and maps SDK failures to {"success": False, "error": ...}. Callers can inject separate client / async_client instances; the tool only creates and closes clients it owns, including on async failure or cancellation. Tests cover schema validation, sync/async parity, lifecycle, cancellation, missing dependency messaging (uv add typesafe-sdk), and public import.

Review summary

Reviewed all 8 changed files (the new JevDecisionTool implementation, exports, README, tests, and uv.lock dependency additions). The tool wraps the typesafe-sdk with a native async _arun path sharing request construction and response formatting with the synchronous _run. Untrusted inputs (state, question, choices) are pydantic-validated and forwarded only to a caller-injected or tool-created SDK client (an operator-configured remote API); there is no local injection sink, no endpoint/authorization surface, and no hardcoded secret (the API key is read from TYPESAFE_API_KEY). Client ownership is handled correctly on both sync and async paths, including closing owned clients and propagating cancellation. No security issues were identified in the changed code.

Explanation

Issue #8123 is open and directly linked. JevDecisionTool._arun awaits AsyncTypeSafeClient.system_one and does not call the synchronous client. The method reuses request construction and response formatting. Tests use fake async clients for request arguments, result parity, SDK failures, cancellation, and ownership. Injected clients are not closed. Tool-created clients are closed in finally. Client creation passes the configured model to the SDK. The tests do not require credentials or paid API calls.

Full details: Out of Scope Changes check

Explanation

The async implementation and tests directly support issue #8123. The synchronous Jev tool, exports, optional dependency, README, and related tests provide the prerequisite tool and public wiring referenced by the PR and support the async API. No unrelated product-area changes are shown. The changes remain within the Jev tool feature scope.

SDK call passes unsupported model argument

High Severity

Both _run and _arun pass model into system_one after already applying it on TypeSafeClient / AsyncTypeSafeClient. The TypeSafe Python API documents model on client construction, not on system_one (state, questions, optional response_model). Tests mock the client, so a real call can fail outright or override an injected client's configured model when self.model is None.
