Conciseness

The 5-phase protocol itself is dense and assumes Claude's competence with no basic-concept padding, but three sections — "Red Flags" (8 bullets), "Common Rationalizations" (8 rows), and "Anti-Patterns" (8 rows) — each restate "don't skip phases / don't fix prematurely" in different clothes, and the two graphviz diagrams largely duplicate the prose ordering. Mostly efficient but could be tightened by merging the overlapping catalogs — anchor 3, not 2, since no section explains concepts Claude already knows and each catalog carries distinct framing.

Actionability

Fully executable guidance throughout: exact commands ("git log --oneline -20 -- <feature-path>"), concrete grep targets (process.env, import.meta.env), filled output templates for every phase, a risk-labeling table with explicit criteria, exact fix ordering (deps → types → logic → tests → integration), and a literal escalation message to deliver verbatim. Copy-paste-ready templates cover the common cases — anchor 5.

Workflow Clarity

Strict 5-phase sequence (SCOPE → TRACE → DIAGNOSE → FIX → VERIFY) with explicit validation checkpoints (run the related test after each fix, verify consumer tests in Phase 5), explicit feedback loops (FIX → DIAGNOSE on regression, 3-strike escalation to architecture discussion), and per-category checklists in Phase 3. Exact match for anchor 5; verification is thorough so no cap applies.

Progressive Disclosure

No bundle files exist, so the skill is single-file by design; sections are clearly headed and a Quick Reference table aids navigation. However ~315 lines are all inline — the phase output templates and the three overlap-heavy catalogs (Red Flags / Rationalizations / Anti-Patterns) are content that could be split into reference files. Good structure with minor organization gaps — anchor 4, not 5, since content that could be separate is inline.

Specificity

Lists several specific actions — "fix, debug, or make a specific feature/module/area work end-to-end" and "systematic deep-dive repair across all files and dependencies" — but omits the skill's distinctive sub-capabilities (scope mapping, dependency tracing, verification). Fits anchor 4 (several specific actions, minor gaps) rather than 3, since more than 1-2 concrete actions are named.

Completeness

Explicitly answers both questions: "Use when the user asks to fix, debug, or make a specific feature/module/area work end-to-end" (when, with concrete trigger phrases) and "systematic deep-dive repair across all files and dependencies" (what), plus an explicit exclusion boundary ("Not for quick single-bug fixes"). Third-person voice, no fluff — matches the anchor-5 example pattern.

Trigger Term Quality

Explicit trigger phrases ("make X work", "fix the Y feature", "the Z module is broken", "focus on [area]") are natural user language, giving good keyword coverage. Common variations like "X isn't working" or "why is Y broken" are missing, so it falls short of the comprehensive-synonym coverage of anchor 5.

Distinctiveness Conflict Risk

"Not for quick single-bug fixes" explicitly distinguishes it from generic debugging skills, and the niche (whole-feature systematic repair vs. single-bug debugging) has distinct, unambiguous triggers. Clear niche with minimal conflict risk — anchor 5.
