Conciseness

The body is table- and code-driven with almost no conceptual padding — exit codes, events, and file locations are compressed into tables, and the bash template is minimal. It falls short of anchor 5 because "Common Matchers" spells out basics Claude already knows (Bash, Edit, Grep) and the "Wildcard Permissions" detail would fit better in a reference file. Not 3, since the padding is minor rather than a section-length problem.

Actionability

Fully executable throughout: a complete settings JSON structure, a copy-paste bash template with jq input parsing and a working exit-2 block pattern, exact commands (`/hooks`, `claude --debug`, `cat .claude/settings.json | jq .`), and three concrete example files (firewall, quality checks, pre-push tests) covering the common cases — matching anchor 5.

Workflow Clarity

"Testing Hooks Safely" is a 4-step sequence with an explicit verify step, and "Verifying Hooks Are Loaded" is a concrete checklist, but there is no single end-to-end create-hook sequence (write script → chmod +x → register in settings → restart → verify); the steps are scattered across sections and `chmod` appears only as a parenthetical. This matches anchor 4 (clear sequence, most checkpoints, minor gaps); the skill is not destructive/batch, so no cap applies.

Progressive Disclosure

The body is an overview with a clearly signaled "You MUST read the reference files" section pointing to four real, one-level-deep files (hook-events.md plus three examples), each annotated with what it contains. Detailed schemas and full examples are correctly kept out of SKILL.md, matching anchor 5 (well-signaled one-level-deep references, easy navigation).

Specificity

Phrases like "create a hook", "add a hook", "write a hook" name the domain and one core action, but the description never states what the skill actually does (e.g., creating hooks that run shell commands on events), which stays only in the body. This matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive) rather than 4, since the triggers are one action phrased three ways rather than several distinct capabilities.

Completeness

The 'when' is explicit and rich ("This skill should be used when the user asks to..."), but the 'what' is only implied through the trigger phrases — there is no explicit capability statement. This sits between anchor 2 ('when' without 'what') and anchor 4 (both present), landing at 3 because the implied 'what' is clear but never stated.

Trigger Term Quality

Natural trigger phrases users would actually say are well covered: "create a hook", "add a hook", "write a hook", "automatically do X", "run X before/after Y", "mentions Claude Code hooks". It falls short of anchor 5 because common synonyms such as "guardrails", "automate", "block commands", or event-driven phrasings are missing.

Distinctiveness Conflict Risk

"Claude Code hooks" is a clear niche with distinct triggers, but "automatically do X" and "run X before/after Y" overlap with closely related configuration/automation skills (e.g., a settings-based hooks skill), matching anchor 4 (mostly distinct, minor overlap risk).
