## Summary
Replaces all 234 bare `@skip` occurrences across 82 Behave feature files with the correct TDD issue-capture tagging system described in CONTRIBUTING.md § Bug Fix Workflow.
Previously, the noxfile ran Behave with `--tags=not @skip`, silently excluding all `@skip`-tagged scenarios from every CI run. These tests never ran, never inverted results via the `@tdd_expected_fail` mechanism, and never contributed to coverage — defeating the purpose of TDD issue-capture testing. Every `@skip` occurrence had a commented-out hint line immediately above it showing the intended proper tags (e.g., `# @tdd_issue @tdd_issue_4272 @tdd_expected_fail @skip`), confirming they were all intended for conversion.
## Changes
### Mechanical conversion (234 replacements across 82 files)
- Extracted the proper TDD tags from the comment hint above each `@skip` line, removed `@skip` from the tag set, and replaced the `@skip` line with those tags.
- Removed the now-redundant comment hint lines alongside each replacement.
### Bug-fixed scenarios — `@tdd_expected_fail` removed (84 scenarios)
- After conversion, ran `nox -s unit_tests` to identify which newly-enabled `@tdd_expected_fail` scenarios now **pass** (their referenced bugs have already been fixed). Removed `@tdd_expected_fail` from those 84 scenarios and their corresponding feature-level tags, leaving only the permanent `@tdd_issue @tdd_issue_<N>` regression-guard tags.
- Affected features include: `tdd_tool_runner_env_precedence`, `tdd_automation_profile_session_leak`, `tls_certificate_check`, `project_create_persist`, `resource_type_bootstrap_*`, and 18 others.
### Noxfile cleanup
- Removed all four `--tags=not @skip` arguments from `noxfile.py` (unit_tests and coverage sessions). With zero `@skip` tags remaining in the codebase, this filter was dead code and its presence would mislead future maintainers into thinking `@skip` is still a supported escape mechanism.
### Regression guard files
- Split the regression guards into two focused files:
- `tdd_regression_guards_exec_env.feature` for bug #4281 (exec-env precedence)
- `tdd_regression_guards_session_list.feature` for bug #4271 (session list summary)
- Each file carries only its own `@tdd_issue` tags at the feature level, avoiding cross-contamination via Behave tag inheritance. The `Background` step (`session-list-summary mock`) only appears in the session-list file where it is actually needed.
### Duplicate tag cleanup
- Removed duplicate `@tdd_issue @tdd_issue_4287` tag lines in `tdd_skill_add_regression.feature` (lines 20 and 29).
### Inline comment for retained `@tdd_expected_fail`
- Added inline comment in `ci_workflow_validation.feature:134` explaining why this specific #4227 scenario retains `@tdd_expected_fail` despite #4227 being closed (CI YAML does not encode threshold as a machine-readable value).
### Known edge cases — `@tdd_expected_fail` retained (closed issues, fix on master, scenarios still fail)
The following issues are **closed** and their fixes **are on master**, but the specific test assertions still fail because the fixes address other aspects of the bugs. The `@tdd_expected_fail` tags are functionally correct and must remain until the specific scenario assertions pass:
- `tdd_exec_env_resolution_precedence.feature` — bug #1080 (closed 2026-03-31). The precedence-level-2-vs-4 scenario still fails.
- `session_list_summary_dedup.feature` — bug #3046 (closed 2026-04-05). The dedup-consistency scenarios still fail.
- `actor_add_update_enforcement.feature` — bug #2609 (closed 2026-04-05). The enforcement scenarios still fail.
- `ci_workflow_validation.feature:134` — #4227 (closed 2026-04-08). The CI YAML threshold assertion still fails.

## Summary
Add the missing `--skill` repeatable flag to `actor run` and `actor-run` CLI commands, aligning the implementation with the specification (CLI Synopsis line 277). The flag enables ad-hoc skill injection at runtime without modifying YAML configuration.
Closes#887
## Changes
### DI Container
- **`container.py`**: Added `_build_skill_service()` factory and `skill_service` Singleton provider, following the established `_build_*` pattern. Falls back to in-memory `SkillService()` when the database is unavailable. Exception handling narrowed to `(ImportError, OperationalError, DatabaseError, OSError)` with `exc_info=True` for traceability.
### CLI Layer
- **`actor.py`**: Added `--skill` Typer option (`list[str] | None`, repeatable, `metavar="NAME"`). Help text notes that skills only augment tool-bearing agents. Wrapped constructor in the existing `try/except` block so `CleverAgentsException` from skill resolution is properly caught.
- **`actor_run.py`**: Same `--skill` option with `metavar="NAME"`. Exception handler catches `CleverAgentsException` (matching master — not broadened to `CleverAgentsError`).
- **`skill.py`**: Removed module-level `_service` cache. `_get_skill_service()` now always delegates to `get_container().skill_service()` so that `reset_container()` correctly invalidates the cached instance. `_reset_skill_service()` now overrides the container's provider via `providers.Object()`. Removed dead `validate_skill_names()` function.
### Runtime Layer
- **`application.py`** (438 lines, down from 625): `ReactiveCleverAgentsApp` gains `skill_names` parameter with automatic deduplication via `dict.fromkeys`. `_resolve_skills()` obtains `SkillService` from the DI container (no CLI layer import). Separate `except KeyError` and `except ValueError` produce distinct error messages (`"not found in registry"` vs `"resolution failed: {exc}"`). Skill tools are only injected into agents that already have tools (`if self._resolved_skill_tools and tools:`), preventing LLM agents from being converted to pass-through `SimpleToolAgent` instances. When skill tools are skipped for tool-less agents, `logger.debug` emits a diagnostic message. `_sanitize_skill_name()` validates skill name format with tightened regex: `^[\w.-]{1,127}/[\w.-]{1,127}$` with `re.ASCII` flag. Zero-tool skill warning now uses `logger.warning` (not `print(stderr)`), ensuring structured log output and proper log-level filtering.
- **`graph_executor.py`** (334 lines): Extracted graph execution logic. Type annotations improved.
### Tests
- 24+ Behave scenarios across feature files covering: single/multiple/unknown skill flags, skill+context combined, duplicate deduplication, skill resolution, ValueError path, zero-tool resolution, error handling, tool merging, default behavior, overrides, LLM agent guard, `_sanitize_skill_name` edge cases (empty string, too-long name, ANSI escape codes, disallowed characters), `_build_skill_service` happy+fallback paths, `_get_skill_service` container delegation.
- CLI "unknown skill" tests for **both** `actor.py` and `actor_run.py` exercise the real error chain (mock only `get_container()`, not the entire `ReactiveCleverAgentsApp`), testing `_resolve_skills()` → `CleverAgentsException` → `except CleverAgentsException` → exit code 2 end-to-end.
- Combined skill+context tests assert `ContextManager` was instantiated and `exists()` was called in dedicated **Then** steps.
- `@coverage` tags added to all new scenarios.
- **Robot Framework smoke tests** added (`robot/skill_actor_run.robot` + `robot/helper_skill_actor_run.py`): unknown-skill error path and valid-skill acceptance path.
### Changelog
- Added entry under `## Unreleased` in `CHANGELOG.md`.
## Review Fixes Applied (Brent Edwards, Rounds 1 & 2)
| # | Finding | Resolution |
|---|---------|------------|
| **P1-1** | `print(stderr)` for zero-tool skill warning | **Fixed** — replaced with `logger.warning("Skill '%s' resolved to zero tools", name)`, removed unused `import sys` |
| **P2-2** | Skill tools silently skipped for tool-less agents | **Fixed** — added `logger.debug` when skipped; updated `--skill` help text to note "only augments tool-bearing agents" |
| **P2-3** | `container.py` at 739 lines | **Acknowledged** — pre-existing growth (+59 lines for `_build_skill_service`); extracting factories is a separate refactoring task |
| **P2-4↑** | `CleverAgentsException` → `CleverAgentsError` broadens catch scope | **Fixed** — reverted `actor_run.py` to `except CleverAgentsException` matching master |
| **P3-5** | No Robot Framework smoke test for `--skill` | **Fixed** — added `skill_actor_run.robot` with 2 test cases (unknown-skill error, valid-skill acceptance) |
| **P3-6** | `GraphExecutor._follow_chained_edges` static-calling-static | **Acknowledged** — cosmetic pattern that doesn't affect correctness; can address in a follow-up |
## Known Limitations / Deferred Items
| Item | Reason |
|------|--------|
| `actor.py` at 679 lines (500-line guideline) | Pre-existing (670 on master), +9 lines for `--skill`. Refactoring the shared `_execute()` closure is a separate task. |
| `container.py` at 739 lines (500-line guideline) | Was 680 lines on master, +59 lines for `_build_skill_service()` and `skill_service` provider. Refactoring into sub-modules is a separate task. |
| Code duplication between `actor.py` and `actor_run.py` `run()` | ~47 lines identical code. Coupled with the line-count issue above — both require extracting shared execution logic into a helper module. |
| `SimpleToolAgent` only executes `tools[0]` | Deferred to #974. Pre-existing architectural limitation, not introduced by this PR. |
| `GraphExecutor._follow_chained_edges` static-calling-static pattern | Cosmetic, doesn't affect behavior. |
