Conciseness

The core workflow (store mapping, touchpoint audit templates, report format, scope control) is lean and every line instructs, but the motivating "New Email" bug is told three times — in "The Problem This Solves", in Step 1's store map, and again in a ~35-line closing example that repeats the full store definition — and Pattern 3 (Stale Closure) and Pattern 2 (Async Race) re-explain React concepts Claude already knows. It is not anchor 2 because the majority of the body is tight, actionable material rather than padding, and not anchor 4 because the redundancy (roughly a quarter of the body, plus the app-specific page inventory in the agent split) is more than minor trimming.

Actionability

The skill supplies copy-paste-ready output templates for store maps ("actionName → {sets: [...], resets: [...]}"), per-touchpoint audits, and bug reports, plus six named patterns with code sketches and a structured report format — highly executable for an instruction-only skill. It falls short of anchor 5 on minor gaps: no method is given for enumerating "EVERY interactive touchpoint" (e.g., grepping for onClick/onSubmit), and the CRITICAL/HIGH/MEDIUM/LOW severity levels are used without definitions, leaving severity assignment to guesswork.

Workflow Clarity

The three-step sequence (map stores → audit touchpoints → report) is clearly ordered with an explicit cross-agent dependency ("Agent 1 MUST complete first. Its output is input for all other agents.") and a six-point CHECK list that functions as a per-touchpoint checkpoint. It misses anchor 5 because there is no verification feedback loop on findings — nothing instructs confirming a suspected reset by reading the store definition or checking other callers before reporting, so false positives can flow straight into the report; it is well above anchor 3, whose sequence lacks checkpoints entirely.

Progressive Disclosure

This is a single-file skill (no references/, scripts/, or assets/ directories exist in the bundle) with clear, well-signaled section headers and a logical overview-to-detail flow. Structure is good, but the ~245-line body inlines content that would fit a one-level-deep reference — the six-pattern catalog and the closing walkthrough — which keeps it below the ideal split of anchor 5 while remaining clearly better organized than the inline-bloat of anchor 3.

Specificity

The description states a concrete action ("Trace every user-facing button/touchpoint through its full state change sequence") and enumerates concrete bug classes ("functions individually work but cancel each other out, produce wrong final state, or leave the UI in an inconsistent state"). It centers on a single core action rather than the multiple distinct actions of anchor 5, but its failure modes are far more concrete than the 1-2 generic actions of anchor 3, placing it noticeably above the midpoint.

Completeness

Both halves are explicit: the "what" is tracing touchpoints through their state-change sequences to find state-interaction bugs, and the "when" is a dedicated "Use when: systematic debugging found no bugs but users report broken buttons, or after any major refactor touching shared state stores" clause with concrete trigger conditions. This directly matches the anchor-5 example structure of clear what plus explicit when with concrete triggers; anchor 4's "when could be more explicit" does not apply.

Trigger Term Quality

Natural phrases a user would say are present — "users report broken buttons", "after any major refactor", "shared state stores" — with relevant technical terms like Zustand-style state implied via "state change sequence". A few common variations are missing ("click", "button does nothing", "nothing happens", "UI"), so it does not reach the comprehensive synonym coverage of anchor 5, but it clearly exceeds the partial coverage of anchor 3.

Distinctiveness Conflict Risk

The niche is distinct — auditing UI handler state interactions (sequential undo, async races, inconsistent final state) — and the trigger clause explicitly differentiates it from generic debugging ("systematic debugging found no bugs but users report broken buttons"), which minimizes the chance of firing for ordinary bug-hunting or API/styling skills. Anchor 4's "minor overlap risk with closely related skills" is not present because the boundary against the nearest neighbor (systematic debugging) is stated in the trigger itself.
