Conciseness

The body is dense and purposeful — a REPL command table, copy-paste CDP driver, pitfalls, and recipes — and does not explain basics Claude already knows, matching anchor 4 (efficient, minor over-explanation that could be trimmed). Not a 5 because a few prose passages (e.g. the Overview and When-to-Use bullets) could be tightened; not a 3 because it is markedly leaner than the 'mostly efficient with some unnecessary explanation' anchor.

Actionability

Provides fully executable, copy-paste-ready guidance across the common cases: 'node inspect path/to/script.js', a complete chrome-remote-interface driver, 'kill -SIGUSR1 <pid>' attach flow, and vitest-under-debugger commands, matching anchor 5. Not a 4 because examples are complete rather than having minor gaps.

Workflow Clarity

Multi-step flows are explicitly numbered (e.g. '1. Send SIGUSR1... 2. Attach the debugger CLI'), a dedicated 'Verification Checklist' provides validation checkpoints, and 'Common Pitfalls' gives error-recovery feedback loops, matching anchor 5. Debugging is not a destructive/batch operation, so the 3-cap does not apply; not a 4 because checkpoints and recovery guidance are explicit rather than minor.

Progressive Disclosure

Content is well-organized with clear section headers (Quick Reference, Attaching, Programmatic CDP, Pitfalls, Recipes) and no broken or nested references — there are no bundle files, so all content is inline but structured, fitting anchor 4 (good structure, well-placed content). Not a 5 because some long inline blocks (the full CDP driver, the CPU/heap profiler snippets) could arguably be split into reference files, and the skill exceeds the under-50-line simple-skill exception.

Specificity

Quotes 'Debug Node.js via --inspect + Chrome DevTools Protocol CLI' — names the domain (Node.js) and the concrete mechanism (inspect flag + CDP), but the only action verb is 'Debug' with no enumeration of capabilities, matching anchor 3 (domain + 1-2 concrete actions, not comprehensive). It is above anchor 2 because the mechanism is concrete rather than generic, and below anchor 4 because no multiple specific actions are listed.

Completeness

It clearly states 'what' (debug Node.js via inspect + CDP CLI) but provides no 'Use when...' or equivalent trigger guidance, so per the missing-trigger clause completeness is capped at 3, matching anchor 3 exactly. Not a 4 because there is no explicit 'when'.

Trigger Term Quality

Natural term 'Debug Node.js' is present, plus technical terms '--inspect' and 'Chrome DevTools Protocol', but common variations users say (breakpoints, stepping, node inspect, pause) are absent, fitting anchor 3 (some relevant keywords, missing common synonyms). Not a 4 because natural synonyms are largely missing; not a 2 because 'Debug Node.js' is a phrase users actually say.

Distinctiveness Conflict Risk

The phrase 'Debug Node.js via --inspect + Chrome DevTools Protocol CLI' carves a narrow niche (Node.js + CDP), with only minor overlap risk against generic or language-agnostic debugging skills, matching anchor 4. Not a 5 because general debugging skills (e.g. systematic-debugging) still partially overlap; not a 3 because it is far more specific than 'Works with document files'.
