feature-ultra
Systematic pre-implementation analysis that finds unknown unknowns — usability gaps, broken flows, state conflicts, concurrency hazards, error dead-ends, and edge cases BEFORE code is written. Fire-and-forget: runs all phases autonomously and delivers a severity-ordered report. Works across stacks — frontend, backend, CLI, mobile, APIs. Use this skill when: (1) before implementing any feature that changes existing behavior, (2) before adding async/background processing to what was synchronous, (3) when a feature touches shared state (global stores, caches, databases, queues), (4) when a feature has multiple entry points or triggers, (5) when moving functionality between surfaces or layers, (6) when the user asks to 'think through' or 'analyze' a feature before building it, (7) when reviewing a plan for hidden failure modes. Triggers on: 'analyze this feature', 'think through the flow', 'what could go wrong', 'check for edge cases', 'will this break anything', 'find problems with this', 'unknown unknowns', flow analysis, impact analysis, pre-implementation review.
Quality
Discovery
SkippedBased on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
Implementation
SkippedReviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
Validation
90%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
