Skill Codex
Converges future-state requirements around outcome, exclusions, and rough cost. Use when users ask 'do we need this?', 'how far should we go?', or request a feature or scope change.
Skill Codex
Evaluates received review results before they generate work by separating problems from proposed fixes and comparing responses in a fixed decision order. Use whenever review results may lead to artifact changes; does not produce reviews.
Skill Codex
Coordinates custom specialists through workflow phases, artifact handoffs, approval gates, and autonomous implementation. Use when executing a workflow recipe or routing its next specialist.
Skill Codex
Repository-aware rules for choosing which tests a change needs, one owning test per claim, observable proof, and test integrity. Use when writing, reviewing, or fixing tests.
Skill Codex
Sets delegation scope, completion waiting, and evidence-based intervention. Use when spawning, waiting for, or steering any subagent, including a single ad hoc agent or a custom workflow agent.
Skill Claude CodeCodex
Monitors development work against its governing outcome at a user-selected interval. Use when asked for periodic independent checks for scope drift or unnecessary work.
