Lists multiple specific concrete actions: tracing button/touchpoint state change sequences, finding bugs where functions cancel each other out, produce wrong final state, or leave UI in inconsistent state. These are concrete, well-defined debugging activities.

Clearly answers both what (trace user-facing buttons through state change sequences to find interaction bugs) and when (explicit 'Use when' clause specifying two triggers: systematic debugging found no bugs but users report broken buttons, or after major refactor touching shared state stores).

Includes some natural terms like 'broken buttons', 'shared state stores', 'major refactor', 'UI inconsistent state', and 'debugging'. However, it misses common variations users might say like 'state management bug', 'click does nothing', 'button not working', 'race condition', or 'UI glitch'.

Highly distinctive niche: specifically targets interaction-level state bugs where individual functions work but combined behavior fails. This is clearly distinguishable from general debugging skills, UI testing skills, or state management skills due to its focus on cross-cutting state interaction bugs.

The skill is mostly efficient and the content is genuinely useful, but it's verbose in places — the 'Problem This Solves' section over-explains what traditional debugging does (Claude knows this), and the motivating example is repeated three times (intro, example section, and referenced throughout). The bug pattern examples are valuable but could be tighter.

Highly actionable with concrete, executable patterns. The step-by-step trace methodology is specific (identify handler → trace calls → check state reads/writes/resets → verify final state). Code examples are real and illustrative, bug patterns include concrete code snippets, and the output format is clearly specified with templates.

Excellent multi-step workflow: Step 1 (map stores) → Step 2 (audit touchpoints) → Step 3 (report). Each step has explicit output formats. The dependency is clear (Step 1 must complete before others). Validation is built into the process — each touchpoint check includes an expected vs actual comparison and a verdict. The agent parallelization guidance includes ordering constraints.

The content is well-structured with clear headers and sections, but it's a long monolithic document (~200 lines) that could benefit from splitting. The bug patterns catalog, the agent split recommendations, and the store mapping methodology could each be separate referenced files. References to other skills are present but the skill itself doesn't offload any detail.
