All notable changes to this project will be documented in this file.
The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
- Fixed AutoDebugAgent LangGraph node contract violations (#10496): `_analyze_error` now
returns a proper state update dict (`{"messages": state.get("messages", []) + [new_message]}`)
instead of a mutated full state, preventing duplicate message accumulation when LangGraph
merges state across nodes. Removes `@tdd_expected_fail` from the TDD test now that the
bug is fixed. Also fixes `typer.Exit` propagation in actor CLI commands (`actor_run.py`,
`actor.py`) so exit codes are correctly preserved through exception handler chains, and
adds `typer.Exit` to Behave step exception handlers so test scenarios no longer error
on `typer.Exit` instead of cleanly capturing the exit code. 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"`).

- **fix(tui): rename ActorSelectionOverlay._render to _refresh_display (issue #11039)** — `ActorSelectionOverlay._render()` shadows Textual's `Widget._render()` which must return a `Strip`. In textual >=1.0, layout calls `get_content_height()` `self._render()` gets `None` `AttributeError: 'NoneType' object has no attribute 'get_height'`. Renamed the method to `_refresh_display()` and updated all four internal call sites (`show()`, `move_up()`, `move_down()`, `set_search()`) to use the new name.
- feat(cli): implement context show and context clear CLI commands for ACMS (#9586): Added `context show <view>` to display assembled context with per-tier budget utilization summary (hot/warm/cold) and `context clear` with --path, --tag, and --tier filtering plus confirmation prompt with --yes bypass.
- **Structural Component Output Validation** (#8164): Replaces exact character matching with structural component checking for output validation. 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`.

- **WF18 container clone e2e test: add `tdd_expected_fail` tag and full test body** (#10815):
The `wf18_container_clone.robot` E2E test was missing its test body — after
`Skip If No LLM Keys` the test case had no steps, but when LLM keys are
present the container clone workflow caused the CLI to be killed by SIGKILL
(rc=-9, OOM) in the memory-constrained CI environment. Added `tdd_expected_fail`
(with `tdd_issue_10815`) so CI correctly inverts the OOM failure to a pass until
the container execution environment is tuned for CI memory limits. Also added the
full WF18 test body covering all acceptance criteria: container-instance resource
registration with `--clone-into`, two-step project creation and resource linking,
action creation with trusted automation profile, and the complete plan lifecycle
(use → execute → apply) with a `WF18 Test Teardown` keyword for diagnostic
logging on failure.
- **`agents session tell --format` outputs JSON envelope** (#10466): Added the
`--format`/`-f` flag to `agents session tell`, enabling machine-readable output
(JSON, YAML, plain, table) alongside the existing Rich console text. When
non-rich formats are selected the response is wrapped in the spec-required JSON
envelope containing `command`, `status`, `exit_code`, `data`, `timing`, and

### Added
- **ContextStrategy Protocol and Plugin Registration System** (#10590): Implemented the
``ContextStrategy`` protocol for pluggable context assembly strategies within the ACMS.
Includes six built-in strategy implementations: ``SimpleKeywordStrategy`` (keyword matching,
quality 0.3), ``SemanticEmbeddingStrategy`` (word-overlap similarity search, quality 0.6),
``BreadthDepthNavigatorStrategy`` (UKO hierarchy traversal with depth/breadth projection,
quality 0.85), ``ARCEStrategy`` (multi-modal pipeline combining text/vector/graph backends,
quality 0.95), ``TemporalArchaeologyStrategy`` (historical pattern discovery from cold-tier data,
quality 0.5), and ``PlanDecisionContextStrategy`` (ancestor plan decision retrieval, quality 0.7).
The ``StrategyRegistry`` provides thread-safe registration, enable/disable configuration,
per-strategy timeout/fragment limits, circuit-breaker tracking, validation warnings, and plugin
discovery from ``"module:ClassName"`` strings with a module-prefix allowlist for security.
Seventy-seven (77) Behave scenarios cover strategy selection by confidence scoring, backend
capability matching, duplicate registration rejection, stale enabled-list detection,
MappingProxyType coercion validators, thread-safety under concurrent access, boundary value
validation via Pydantic model constraints, and per-strategy config updates.

- **`context_tier_hydrator` module documented in ACMS architecture section** (#9208): Added
a new **Context Tier Hydration** subsection to the ACMS Architecture section of the
specification (`docs/specification.md`), documenting the `context_tier_hydrator` module's
public interface (`hydrate_tiers_for_plan`, `hydrate_tiers_from_project`), file listing

10 MB total per project), and fragment structure (`TieredFragment` with HOT tier placement
and metadata keys `path`, `detail_depth`, `relevance_score`). Closes #6175.

- **Spec clarifications: layer boundary DI exception, ULID scope, TUI/ACMS gaps** (#10451): Added targeted clarifications to `docs/specification.md` including: the sole permitted location (`application/container.py`) where application layer may reference infrastructure concrete types; distinction between domain entity IDs (must be ULID) and ephemeral internal implementation IDs; per-stage protocol contracts, storage tier definitions, budget enforcement protocol, and output format for ACMS pipeline stages; and public interface definitions with verifiable checks for 8 TUI components.
### Security
- **PyYAML dependency pinned to secure version** (#9055): Added an explicit
`pyyaml>=6.0.3` constraint to `pyproject.toml` to address CVE-2017-18342

downstream consumers could still invoke `yaml.load()` without an explicit
safe Loader. A codebase-wide audit confirmed all YAML loading uses
`yaml.safe_load()` exclusively (via `cleveragents.actor.yaml_loader`).
Added BDD regression scenarios in `features/pyyaml_security.feature` to
verify the version constraint and safe-load enforcement are maintained.

parallel dispatch → hierarchical lifecycle → parent wait). Specifies concurrency control
via per-plan semaphores (`max_parallel` default 4, max 16, `fail_fast` support).
Documents integration points with Plan Executor, Three-Way Merge, Decision Recording,
and Checkpoint System. Defines four error types with typed signatures for spawn,
execution, concurrency, and depth-limit failures. Covers cross-cutting concerns:
metrics observability, INFO-level lifecycle logging, cancellation propagation, and
per-subplan timeouts (default 30 min).

- **Plan Tree CLI Command** (#8525): Implemented `agents plan tree <plan-id>` command for
visualizing decision trees in the v3 plan lifecycle. The command renders a hierarchical
tree structure showing decision hierarchy with per-type ordinal labeling, superseded
decision filtering (via `--show-superseded`), depth limiting (via `--depth`), and
multiple output formats (rich, plain, table, json, yaml). Each node displays decision
ID, type, question, and chosen option. Corrected nodes are visually marked via the
`is_superseded` flag. The command handles empty decision trees gracefully and includes
ULID validation and proper error handling consistent with other plan commands.

- **container-instance --clone-into and devcontainer-instance sandbox strategy** (#7555):
Added `--clone-into` CLI argument to `container-instance` resource type for cloning
a git repository into a running container. Implemented `CloneIntoHandler` with
`clone_repo_into_container()` and `validate_clone_into_url()` helpers. Updated
`devcontainer-instance` to use `snapshot` sandbox strategy (was `none`) to enable
safe plan execution inside containers. Added `container-mount`, `container-exec-env`,
and `container-port` as child types of `devcontainer-instance`. Renamed
`ContainerLifecycleState.DETECTED` to `DISCOVERED` (value: `"discovered"`) to align
with specification terminology.
- **Plan checkpoint management CLI commands** (#8683): Added `agents plan checkpoint-list <plan-id>` and `agents plan checkpoint-delete <checkpoint-id>` commands. Listing output now highlights checkpoint ID, type, created timestamp, reason, phase, and decision linkage with a concise field summary footer across rich/table/json/yaml formats. Deletion supports batch IDs, interactive confirmation (skip with `--yes`), and structured JSON/YAML responses for automation-friendly scripting.
- **Invariant Remove CLI Command** (#8530): Implemented `agents invariant remove <id>` command that soft-deletes an invariant by ID.

Supports `--format` flag for JSON and YAML output. Full BDD test coverage and Robot Framework integration tests included.
- **TDD: plan tree does not visually mark corrected nodes** (#8576): Added a failing
BDD scenario proving that corrected nodes (decisions with `is_correction=True`) are
not visually distinguished in the `agents plan tree` output. The scenario is tagged
`@tdd_expected_fail` and will pass (by inversion) until the underlying gap described

or `BaseException`. Rules detect `except Exception`, `except BaseException`,
`contextlib.suppress(Exception)`, and `contextlib.suppress(BaseException)` patterns.

coverage for the PureGraph module, which previously had orphaned Behave step definitions
(`features/steps/pure_graph_coverage_steps.py`) with no driving scenarios. The PureGraph
scenarios (topological ordering, function execution with dependency resolution, missing
function fallback behavior, and inert non-functional node handling) are wired through
`features/consolidated_langgraph.feature` to reuse the existing step definitions without
introducing a duplicate standalone feature file. Introduces Robot Framework integration
tests in `robot/langgraph/pure_graph.robot` (backed by the
`robot/langgraph/pure_graph_lib.py` Python library) exercising the PureGraph workflow
end-to-end. Includes ASV benchmarks in `benchmarks/pure_graph_bench.py` measuring

## [3.3.0] — Unreleased (Milestone: Corrections + Subplans + Checkpoints)
> **Status:** In progress. Features documented in [`docs/subplans.md`](docs/subplans.md)
> and [`docs/cli.md`](docs/cli.md).
### Added
- **Decision Correction — Revert Mode** (`agents plan correct --mode=revert`):
Invalidates a targeted decision and all its descendants via BFS traversal.
Associated artifacts are archived and affected child plans are rolled back.
The plan re-executes from the corrected decision point. Dry-run support via
`--dry-run` shows full impact report (affected decisions, files, child plans,
risk level) without making changes.
- **Decision Correction — Append Mode** (`agents plan correct --mode=append`):
Preserves the original decision and spawns a new child plan rooted at the
target node. The child plan carries operator guidance (`--guidance`) and
produces additional decisions without disturbing the existing tree.
- **Correction Attempt Tracking** (`CorrectionAttemptRecord`): Each execution
of a correction is tracked as an attempt record with full state lifecycle
(`pending -> executing -> complete/failed`). Multiple attempts may exist per
correction. See [`docs/reference/decision_correction.md`](docs/reference/decision_correction.md).
- **Subplan Execution Service** (`SubplanExecutionService`): Executes child plans
in `sequential`, `parallel`, or `dependency_ordered` mode. Supports `fail_fast`,
per-subplan timeouts, and configurable retry policies.
- **Subplan Merge Service** (`SubplanMergeService`): Merges child plan sandbox
outputs using `git_three_way`, `sequential_apply`, `fail_on_conflict`, or
`last_wins` strategies.
- **Checkpoint and Rollback** (`agents plan rollback <plan_id> <checkpoint_id>`):
Operators can restore sandbox state to any previously captured checkpoint.
Rollback is blocked for plans in the `applied` terminal state or with cleaned-up
sandboxes. See [`docs/reference/checkpointing.md`](docs/reference/checkpointing.md).
- **Automatic Checkpoint Triggers**: The execution engine now creates checkpoints
automatically on `on_tool_write`, `on_tool_write_complete`, `on_subplan_spawn`,
and `on_error` triggers. Configurable via `core.checkpoints.auto_create_on`.
- **Documentation**: Added [`docs/subplans.md`](docs/subplans.md) (subplans and
checkpoints guide) and extended [`docs/cli.md`](docs/cli.md) with all v3.3.0
CLI commands.

## [3.2.0] — Unreleased (Milestone: Decisions + Validations + Invariants)
> **Status:** In progress. Features documented in [`docs/decisions.md`](docs/decisions.md)
> and [`docs/cli.md`](docs/cli.md).
### Added
- **Decision Recording**: Every choice point in a plan's lifecycle is recorded as
a persistent `Decision` node in a tree. Decisions capture the question, chosen
option, alternatives considered, confidence score, rationale, actor reasoning,
and a context snapshot for replay. 11 decision types cover all phases of plan
execution. See [`docs/reference/decision_model.md`](docs/reference/decision_model.md).
- **Decision Service** (`DecisionService`): Application-layer interface for
recording decisions, retrieving decision histories, managing context snapshots,
and performing tree operations (BFS traversal, path-to-root). Supports both
in-memory and persisted modes. See
[`docs/reference/decision_service.md`](docs/reference/decision_service.md).
- **Decision Tree Visualization** (`agents plan tree <plan_id>`): Renders the
decision tree for a plan as a visual hierarchy. Supports `--show-superseded`
to include corrected decisions and `--depth` to limit tree depth.
- **Decision Explain** (`agents plan explain <decision_id>`): Shows detailed
information about a single decision node including alternatives, context
snapshot, and actor reasoning. Supports `--show-context` and `--show-reasoning`.
- **Invariant System** (`agents invariant add/list/remove`): Natural-language
constraints that govern plan execution. Invariants are scoped to `GLOBAL`,
`PROJECT`, `ACTION`, or `PLAN` level with a defined precedence hierarchy.
The Invariant Reconciliation Actor evaluates all invariants at the start of
the Strategize phase and records `invariant_enforced` decisions.
See [`docs/reference/invariants.md`](docs/reference/invariants.md).
- **Invariant Violation Model**: When an invariant is violated, an
`InvariantViolation` is created with `error`, `warning`, or `info` severity.
Reconciliation failures block phase transitions with `ReconciliationBlockedError`.
- **Documentation**: Added [`docs/decisions.md`](docs/decisions.md) (decision
system guide) and [`docs/cli.md`](docs/cli.md) (v3.2.0 and v3.3.0 CLI
command reference).

**Only catch exceptions when you can meaningfully handle them** (e.g., retry logic, resource

#### Escape Hatch: Intentional Exception Suppression
In rare cases, you may have specific recovery logic that justifies suppressing a broad exception.
This is permitted **only** when:
1. You have documented recovery logic that handles the exception meaningfully
2. You add the **Semgrep suppression comment** `# nosemgrep: python-no-suppressed-exception` (or `# nosemgrep: python-no-suppress-exception` for contextlib.suppress)
3. You ALSO add the **human-readable annotation** `# error-propagation: allow` on the same line
4. You include an inline comment explaining why the suppression is safe
**Both comments are required together:**
- The `# nosemgrep` comment is the actual suppression mechanism (Semgrep native) that disables the Semgrep rule check
- The `# error-propagation: allow` annotation is required for human auditability and code review clarity
**Example of allowed suppression (try/except):**
```python
try:
resource.cleanup()
except Exception: # nosemgrep: python-no-suppressed-exception # error-propagation: allow
pass # Resource already cleaned up; safe to ignore
```
**Example with contextlib.suppress:**
```python
with contextlib.suppress(Exception): # nosemgrep: python-no-suppress-exception # error-propagation: allow
resource.cleanup() # Resource already cleaned up; safe to ignore
```
**Automated Enforcement:**
The Semgrep rules `python-no-suppressed-exception` and `python-no-suppress-exception` enforce
this policy. They use Semgrep's native `# nosemgrep` mechanism for suppression, with `# error-propagation: allow`
as a required human-readable annotation for auditability. These rules are run as part of `nox -s lint`
and in the pre-commit hook `semgrep-eval-exec`.
