Summary

Implements the builtin/context skill for the Context Request Protocol (CRP), wiring the three existing tool stubs to the ACMS pipeline and ContextTierService.

Closes #873

Changes

src/cleveragents/skills/builtins/context_ops.py

• request_context: Sources fragments from ContextTierService (all tiers), filters by query/focus keywords, and delegates to ACMSPipeline.assemble() for budget-constrained context assembly. Accepts optional plan_id for actor-context invocation.
• query_history: Searches across hot/warm/cold tiers for fragments matching the query string via case-insensitive substring matching. Returns results sorted by last-accessed timestamp.
• get_context_budget: Returns current token budget state (max, reserved, available, used) computed from ContextBudget defaults and hot-tier fragment token counts.
• build_context_skill_definition(): New factory function that creates a SkillDefinition for builtin/context with all 3 resolved tool entries, ready for SkillRegistry registration at startup.
• Added plan_id as optional parameter to request_context input schema.

src/cleveragents/application/container.py

• Registered ACMSPipeline as a providers.Singleton in the DI container, wired with settings and unit_of_work.

src/cleveragents/skills/builtins/__init__.py

• Added documentation for build_context_skill_definition() factory.

features/crp_models.feature

• Replaced 3 obsolete NotImplementedError stub test scenarios with 8 new functional BDD scenarios:
  • request_context returns assembled context with fragments
  • request_context returns empty result with no stored fragments
  • request_context filters fragments by query
  • request_context filters fragments by focus targets
  • query_history returns entries / empty entries
  • get_context_budget returns budget state / reports used tokens
  • builtin/context SkillDefinition can be built

features/steps/crp_models_steps.py

• Replaced stub step definitions with functional steps that set up DI overrides with test ContextTierService instances and verify handler outputs.

Motivation

The specification defines CRP as the structured vocabulary through which actors declare needed information, accessed "via builtin/context skill." The CRP domain models and ACMS pipeline were already implemented, but no skill existed to expose them. Actors had no way to programmatically request context during plan execution.

Design Decisions

1. Lazy DI lookup — Handlers access services via get_container() at invocation time to avoid circular imports and enable test overrides.
2. TieredFragment → ContextFragment bridging — Helper function converts between the tier service's storage format and the pipeline's input format.
3. Simple keyword matching — v1 uses case-insensitive substring matching; semantic/vector search is a future concern.
4. Optional plan_id — Supports both actor-context invocation (plan_id provided) and standalone testing (auto-generated ULID).

Quality Gates

• Lint: All checks passed
• Typecheck (Pyright): 0 errors
• Unit tests: 48/48 CRP scenarios passed, 140/140 steps passed
• Coverage: 98% overall, 98% for context_ops.py

## Summary Implements the `builtin/context` skill for the Context Request Protocol (CRP), wiring the three existing tool stubs to the ACMS pipeline and ContextTierService. Closes #873 ## Changes ### `src/cleveragents/skills/builtins/context_ops.py` - **`request_context`**: Sources fragments from `ContextTierService` (all tiers), filters by query/focus keywords, and delegates to `ACMSPipeline.assemble()` for budget-constrained context assembly. Accepts optional `plan_id` for actor-context invocation. - **`query_history`**: Searches across hot/warm/cold tiers for fragments matching the query string via case-insensitive substring matching. Returns results sorted by last-accessed timestamp. - **`get_context_budget`**: Returns current token budget state (max, reserved, available, used) computed from `ContextBudget` defaults and hot-tier fragment token counts. - **`build_context_skill_definition()`**: New factory function that creates a `SkillDefinition` for `builtin/context` with all 3 resolved tool entries, ready for `SkillRegistry` registration at startup. - Added `plan_id` as optional parameter to `request_context` input schema. ### `src/cleveragents/application/container.py` - Registered `ACMSPipeline` as a `providers.Singleton` in the DI container, wired with `settings` and `unit_of_work`. ### `src/cleveragents/skills/builtins/__init__.py` - Added documentation for `build_context_skill_definition()` factory. ### `features/crp_models.feature` - Replaced 3 obsolete `NotImplementedError` stub test scenarios with 8 new functional BDD scenarios: - `request_context` returns assembled context with fragments - `request_context` returns empty result with no stored fragments - `request_context` filters fragments by query - `request_context` filters fragments by focus targets - `query_history` returns entries / empty entries - `get_context_budget` returns budget state / reports used tokens - `builtin/context SkillDefinition` can be built ### `features/steps/crp_models_steps.py` - Replaced stub step definitions with functional steps that set up DI overrides with test `ContextTierService` instances and verify handler outputs. ## Motivation The specification defines CRP as the structured vocabulary through which actors declare needed information, accessed "via builtin/context skill."

Review: APPROVED

Good implementation replacing 3 NotImplementedError stubs with real implementations wired to the ACMS pipeline and ContextTierService. The build_context_skill_definition() factory is clean, structured helpers like _tiered_to_pipeline_fragment and _fragment_to_dict are well-named, and proper structlog logging is used throughout. 11 new BDD scenarios cover the main paths.

Items to Note

1. Direct access to private tier attributes. The code accesses tier_service._hot, _warm, _cold directly — this creates fragile coupling to the internal tier service implementation. Consider adding a public method like tier_service.all_fragments() to the ContextTierService API instead.

2. No Robot Framework integration tests present in this diff. Noted for consistency with the multi-level testing mandate.

3. _scope parameter in query_history is accepted but unused (dead code path). Either implement it or remove the parameter to keep the interface honest.

Addressed the minor follow-up review notes in this update:

• Switched builtin/context handlers to use new public ContextTierService accessors (get_all_fragments() / get_hot_fragments()) instead of reaching into private tier stores.
• Removed the unused scope input from query_history so the tool schema matches current runtime behavior.

I also rebased the branch on latest master and pushed the update.
