From 153acf08613e97c1be79b2e15451f31e138058f8 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Tue, 14 Apr 2026 09:43:11 +0000 Subject: [PATCH 01/11] chore(testing): enforce semgrep gate for suppressed exceptions Added two new Semgrep rules to enforce the CONTRIBUTING.md guideline against broad exception suppression: - python-no-suppressed-exception: Detects except Exception/BaseException blocks without re-raising - python-no-suppress-exception: Detects contextlib.suppress(Exception/BaseException) usage Both rules support an escape hatch annotation '# error-propagation: allow' for documented recovery logic. Integrated Semgrep into the nox lint session to run alongside Ruff checks. Updated CONTRIBUTING.md to document the escape hatch policy and automated enforcement. Pre-commit hook already configured to run these rules.

Semgrep strips comments from the AST, so pattern-not clauses looking for inline comments never match. The native `# nosemgrep` comment is properly supported by Semgrep and provides a reliable override mechanism. 2. **Missing exception chaining pattern**: Added `raise $EXC from $CAUSE` pattern-not entries for both `Exception` and `BaseException` variants. This prevents false positives when legitimate exception chaining is used (e.g., `raise ServiceError("context") from e`), which is an allowed pattern per CONTRIBUTING.md. Updated both `python-no-suppressed-exception` and `python-no-suppress-exception` rules with these fixes. The escape hatch now works reliably and exception chaining is properly recognized as an allowed pattern.

Strengthen BDD bare re-raise assertion: replace weak string search for 'raise' with structured parsing of YAML pattern-not entries to specifically verify bare raise patterns exist within the rule's pattern-not configurations. 3. Add CHANGELOG.md entry under [Unreleased] documenting the Semgrep guard implementation and its audit-mode migration strategy.

Removes `@tdd_expected_fail` from the TDD test now that the - bug is fixed.

Adds BDD node-contract - tests for `_generate_fix`, `_validate_fix`, and `_finalize`. Changed `wf10_batch.robot` to be less likely to create files, and `plan_generation_graph.robot` to give more test answers. ## [Unreleased] -- **feat(a2a): A2A stdio transport for local-mode subprocess communication (#691):** Implemented ``A2aStdioTransport`` class providing JSON-RPC 2.0 message framing over stdin/stdout for communicating with an agent subprocess in local mode. Features include process lifecycle management (``connect``, ``disconnect`` with graceful shutdown via wait-then-terminate-then-kill), request/response serialization and deserialization, type-safe path resolution (Python module paths use ``python -m``, ``.py`` files execute directly, executables run without interpreter prefix), and comprehensive error handling for subprocess lifecycle events. Added full BDD test suite covering all code paths in ``features/a2a_stdio_transport.feature`` with mock-based step definitions. -- **fix(a2a): .py path routing in A2aStdioTransport (#691):** Corrected ``connect()`` to use direct script execution (``[sys.executable, agent_path]``) for literal ``.py`` file paths instead of routing through ``python -m``, which expects a module name. Module paths (``cleveragents.*``) continue to use ``-m``; bare executables remain unchanged. -- **feat(resources): resource type extension interface** (#9998): New `cleveragents.resources` package providing the stable public API third-party developers use to add custom resource types without modifying core code. Includes `ResourceType` ABC with five abstract lifecycle methods (`provision`, `deprovision`, `status`, `validate_config`, `to_dict`), a `ResourceConfig` Pydantic model (`name`, `resource_type`, `properties`), a `ResourceStatus` StrEnum (`PENDING`, `ACTIVE`, `FAILED`, `DEPROVISIONED`), and registry functions `register_resource_type` / `get_resource_type` / `list_resource_types`. Custom types are registered under namespaced names (e.g. `myorg/database`); registration raises `TypeError` for non-`ResourceType` subclasses and `ValueError` for duplicate names. 25 BDD scenarios in `features/resource_type_extension_interface.feature` cover enum values, config instantiation, ABC enforcement, all lifecycle method return types, and registry CRUD + error paths. -- **refactor(a2a): route CLI→Application communication through A2A boundary** (Refs #9962, #4253): Introduced `cleveragents.shared.output_format` as a layer-neutral serialiser (`format_data` supporting `json`/`yaml`/`plain`/`table`) with no dependency on `cleveragents.cli.*`, eliminating a reverse dependency from `PlanApplyService.artifacts()` on the CLI presentation layer. The shared formatter returns raw payloads with no CLI envelope wrapping (`{"data": ..., "command": ..., "status": ...}`); callers that previously parsed `parsed["data"]` from `apply_service.artifacts(fmt="json")` output now read fields at the top level. Updated `features/steps/plan_diff_artifacts_steps.py` (`step_artifacts_json_validation`, `step_artifacts_json_apply_summary`) to drop the stale envelope unwrap that caused `KeyError: 'data'` under the new boundary. Removed stale `@tdd_expected_fail` tag from `WF02 Mocked Generation Produces Test Artifacts Only` in `robot/wf02_test_generation_integration.robot` — the scenario now passes naturally through the A2A facade dispatch path (`_cleveragents/plan/artifacts`) introduced by this refactor. -- **fix(test): move advanced context strategy test doubles to features/mocks** (#7574): Extracted `FakeEmbeddings`, `RelevanceScoringStrategy`, `AdaptiveContextSelector`, `ContextFusionStrategy`, and `_pack_budget` from `features/steps/advanced_context_strategies_steps.py` into a new `features/mocks/advanced_context_strategies_mocks.py` file per CONTRIBUTING.md mock-placement rules. Updated the Robot Framework helper `robot/helper_advanced_context_strategies.py` to import directly from `features.mocks` rather than manipulating `sys.path` to reach the Behave steps file. Added `None` guard in `step_assemble_context_query` before calling `selected.assemble()`, and added explicit `ValueError` for unknown strategy types in both `step_load_yaml_strategy` and `load_strategy_from_yaml_impl`. -- **fix(a2a): regression tests for stale cleveragents.acp removal** (#5566): Added two Behave BDD scenarios verifying that `cleveragents.acp` is not importable (raises `ImportError`) and that `src/cleveragents/acp/` does not exist in the source tree. These guard against regression of the `__pycache__`-based import that allowed the removed ACP module to still be loaded from bytecode after the v3.6.0 rename to `a2a`. -- **Virtual Resource Type Base Class** (#8610): Implemented `VirtualResource` base class with two example concrete implementations (`MetricResource`, `APIEndpointResource`) for abstract/computed resources that are derived rather than mapped to physical files. Virtual resources are computed on demand via a `compute_fn` callable. Includes Behave BDD scenarios in `features/resource_virtual_types.feature` exercising construction, computation, name validation, kwargs passthrough, exception handling, string representation, and subclassing. Resource names are validated against `^[a-zA-Z][a-zA-Z0-9_-]*$` (must start with a letter; alphanumeric, hyphens, and underscores otherwise). -- **test(e2e): restore complete M2 acceptance test** (#11191): Restored the truncated M2 full actor compiler and LLM integration e2e acceptance test to its complete 10-step form. Added dynamic LLM provider selection via `Resolve LLM Actor` (falls back to Anthropic when OpenAI is unavailable or quota-exhausted), replacing hardcoded `gpt-4` / `openai/gpt-4` references in the actor config and action YAML. Added explicit return-code validation (`Should Be Equal As Integers ${r_actor.rc} 0`) for the actor registration step. -- **docs(a2a): ACP to A2A migration guide** (#10230): Added migration guide documenting how to upgrade from the ACP module to the A2A module introduced in v3.6.0, including symbol renames, field renames, operation-name mappings, and YAML configuration updates. -- **feat(plans): parallel subplan execution scheduler** (#9555): Added `ParallelSubplanScheduler` with configurable `max_parallel` concurrency control, dependency-ordered execution (`SEQUENTIAL`, `PARALLEL`, `DEPENDENCY_ORDERED` modes), fail-fast mode, per-subplan timeout enforcement, retry support, and pluggable merge strategies. The scheduler delegates execution to `SubplanExecutionService` and exposes `schedule()`, `get_queue_status()`, `get_available_slots()`, and `can_accept_more()` APIs. Includes comprehensive BDD test coverage in `features/parallel_subplan_scheduler.feature`. -- **Plan Prompt JSON Timing Field** (#9353): `agents plan prompt --format json` now - includes `timing.started` as an ISO 8601 UTC timestamp in the JSON envelope, - matching the spec (§CLI Commands — `agents plan prompt`). Extended - `cleveragents.cli.formatting.format_output` (and `_build_envelope`) with an - optional `started_at: datetime` parameter; when provided, the envelope's - `timing` dict includes a `started` field alongside `duration_ms`. Refactored - `prompt_plan_cmd` to delegate envelope construction to `format_output` so the - envelope keys (`command`, `status`, `data`, `timing.started`, `messages`) are - populated correctly at the JSON root rather than nested under a synthetic - inner `data` field. -- **fix(plan): NamespacedName digit-start validation** (#2145, #2147): `NamespacedName` field validators now reject `namespace` and `name` components whose first character is a digit, raising `pydantic.ValidationError` with message `"must start with a letter"`. BDD constructor scenarios updated to use the `"a Pydantic ValidationError should be raised"` step so the assertion correctly matches the exception type raised by Pydantic model construction. - **fix(cli/plan): plan correct JSON output envelope fix and BDD test coverage** (#8584 / PR #8662): Restructured `agents plan correct --format json` output to nest correction fields under `data.correction` (e.g., `data.correction.mode`) and populate the spec-required CLI envelope with `command="plan correct"`, `status`, `exit_code`, `timing`, and `messages` fields. Added three BDD scenarios in `features/tdd_plan_correct_json_output.feature` validating the envelope structure for both revert and append modes. - **fix(cli): add --url flag to resource add for git resource type** (#6322): Added support for the `--url` flag on `agents resource add git` command, allowing users to specify a remote URL for git resources. The flag is validated to only apply to git resource types. Includes Behave BDD tests in `features/resource_cli_git_url_flag.feature` and Robot Framework integration tests verifying correct URL validation and CLI behavior. - **Session create JSON envelope** (#6441): Fixed `agents session create --format json` returning a flat `data` dict instead of the spec-required nested structure with `data.session`, `data.settings`, and `data.actor_details` sub-objects. The `command` field is now populated correctly. Extended JSON envelope coverage to `agents session list`, `show`, `delete --format json`, `export --output-format json`, and `import --format json` so all session commands emit a structured `messages[].text` field (`"0 sessions listed"`, `"Session details loaded"`, `"Session deleted"`, `"Export completed"`, `"Import completed"`). @@ -165,8 +135,6 @@ ensuring data is stored with proper parameter values. - **fix(tui): rename ActorSelectionOverlay._render to _refresh_display (issue #11039)** — `ActorSelectionOverlay._render()` shadows Textual's `Widget._render()` which must return a `Strip`.

Implements three validators covering plan tree output, decision CLI dicts, and structured session snapshots. The `validate_plan_tree` function validates node dicts for required keys (`decision_id`, `type`, `sequence`, `question`, `children`), ULID format, correct types, and sibling ordering. The `validate_decision_dict` function validates decision CLI output against the `Decision.as_cli_dict()` schema with field presence, type, ULID pattern, confidence range [0..1], and boolean field checks. The `validate_structured_output` function validates the StructuredOutput envelope for `command`, `session_id` (ULID), status membership, `exit_code`, and elements integrity. A unified dispatcher (`validate_structured_component_output`) enables routing by target_type. BDD test coverage added in `features/structural_validation.feature`.
