What problem does it solve? Feature specs, acceptance criteria, plans, and charters drift out of sync as a project evolves, causing silent contradictions that surface late in development. This Skill audits all DAE artifacts read-only and reports every inconsistency with a suggested fix. ## Core Features & Use Cases - Mechanical ontology checks: Runs deterministic set-operation checks (AC↔scenario coverage, parent/child inverses, cycle detection, Principle 7 verifier independence) via the dae_ontology.py script. - Judgment checks: Flags issues a script cannot decide, such as ACs leaking implementation language or plans ignoring declared validation methods. - Feature and project scopes: Audit one feature's artifacts or project-wide invariants like charter/manifest role alignment and feature numbering. - Use Case: Before promoting a feature from spec to plan, run a feature-scope consistency check to confirm every AC has a covering spec scenario and all handoffs are complete. ## Quick Start Ask the agent to run a consistency check on the current feature to verify the specs and acceptance criteria are in sync.
