Summary

Implements the ACMS skeleton compressor service for context inheritance between parent and child plans.

Closes #194

Approach

• SkeletonMetadata (frozen Pydantic model): records compression ratio, original/compressed token counts, and source decision IDs for auditability. Persisted on the Plan model as skeleton_metadata.
• SkeletonCompressorService: stateless service that accepts context fragments and a skeleton_ratio in [0.0, 1.0], sorts fragments by relevance (descending, stable), and greedily selects fragments within a token budget of original_tokens * (1 - ratio).
• Ratio semantics: 0.0 = pass-through, 1.0 = max compression (single top fragment), default = 0.3.
• Deterministic ordering: stable sort on (-relevance, fragment_id) ensures identical inputs always produce identical output.
• DI registration: skeleton_compressor_service singleton in the container.

## Summary Implements the ACMS skeleton compressor service for context inheritance between parent and child plans. Closes #194 ## Approach - **SkeletonMetadata** (frozen Pydantic model): records compression ratio, original/compressed token counts, and source decision IDs for auditability. Persisted on the `Plan` model as `skeleton_metadata`. - **SkeletonCompressorService**: stateless service that accepts context fragments and a `skeleton_ratio` in [0.0, 1.0], sorts fragments by relevance (descending, stable), and greedily selects fragments within a token budget of `original_tokens * (1 - ratio)`. - **Ratio semantics**: 0.0 = pass-through, 1.0 = max compression (single top fragment), default = 0.3. - **Deterministic ordering**: stable sort on `(-relevance, fragment_id)` ensures identical inputs always produce identical output. - **DI registration**: `skeleton_compressor_service` singleton in the container. ## Changes ### New files (8) - `src/cleveragents/domain/models/core/skeleton_metadata.py` - `src/cleveragents/application/services/skeleton_compressor.py` - `docs/reference/skeleton_compressor.md` - `features/skeleton_compressor.feature` (22 scenarios) - `features/steps/skeleton_compressor_steps.py` - `robot/skeleton_compressor.robot` (6 smoke tests) - `robot/helper_skeleton_compressor.py` - `benchmarks/skeleton_compressor_bench.py` ### Modified files (6) - `src/cleveragents/domain/models/core/plan.py` — added `skeleton_metadata` field - `src/cleveragents/domain/models/core/__init__.py` — exported `SkeletonMetadata` - `src/cleveragents/application/services/__init__.py` — exported service symbols - `src/cleveragents/application/container.py` — registered service - `vulture_whitelist.py` — added public API entries - `CHANGELOG.md` — added entry ## Quality Gates - Lint: passed - Typecheck: 0 errors (Pyright strict) - Unit tests: 22/22 skeleton scenarios pass - Integration tests: 6/6 Robot tests pass - Coverage: 97% (meets threshold) - Benchmarks: validated at 10/100/1000 fragment scales

Labels

Clear labels   

auto/needs-reevaluation

Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.

  

controller-managed

Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.

  

auto/blocked-by-deps

PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

  

auto/ci-timeout

Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

  

auto/claimed-implementer

Currently being processed by an implementer worker.

  

auto/claimed-merge

Currently being processed by the merge driver.

  

auto/claimed-reviewer

Currently being processed by a reviewer worker.

  

auto/driver-down

Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

  

auto/invariant-violation

Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

  

auto/last-attempt-tier-0

In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-1

In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

  

auto/last-attempt-tier-2

In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

  

auto/last-attempt-tier-min

In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

  

Automation Tracking

Tracking issues used by the AI Automation system for agents to communicate and report.

  

auto/needs-conflict-resolution

Rebase conflict needs LLM conflict-resolver.

  

auto/needs-implementer

Failing CI needs implementer attention.

  

auto/postmortem

Documenting a driver incident or rollback.

  

auto/ready-to-merge

Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

  

auto/restart-throttled

Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  

auto/revert

Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  

auto/sentinel

Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

  

auto/stale-inactivity

No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

  

auto/unstable

Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.

  

Blocked

A ticket in a blocked state and unable to complete until some other task is completed first.
