Conciseness

The content is concrete rather than fluffy — no paragraphs explaining concepts Claude already knows — but there is substantial duplication: the 'Safety Mechanisms' section re-pastes three code snippets already shown in full in the autonomous-loop.sh listing, and 'Operations' repeats the Quick Start's install_autonomous_hooks() call. Hook Configuration, Hook Types, and Operations also demonstrate the same installs three different ways. This is 'mostly efficient but could be tightened' (anchor 3) rather than anchor 2, since the padding is duplication of useful content rather than unnecessary explanation.

Actionability

Mostly executable guidance: the full bash stop-hook script, the settings.json config, and Python calls that match the real scripts/hooks_manager.py API (verified: install_stop_hook, install_pre_tool_hook, install_post_tool_hook, install_session_hooks, remove_hook, get_status, validate all exist). Minor gaps keep it from anchor 5: 'project_dir' is undefined in the Quick Start snippet, and three of the four listed scripts (autonomous-loop.sh, analyze.py, hook_installer.py) do not exist in the bundle.

Workflow Clarity

The core Stop-hook flow is clearly sequenced (numbered steps 1-4 with explicit CONTINUE/COMPLETE decision branches and the critical stop_hook_active check), and the hook lifecycle is enumerated with a validate() operation. It falls short of anchor 5 because there is no error-recovery feedback loop after validation ('if errors: fix and re-run') — validate() only prints errors — which matters since installing hooks mutates .claude/settings.json.

Progressive Disclosure

There is real structure — dedicated References and Scripts sections with one-line descriptions, clearly signaled — but all three listed reference files (references/HOOK-MECHANICS.md, references/STOP-HOOK.md, references/SAFETY.md) are missing from the bundle, as are 3 of the 4 listed scripts. Meanwhile deep-dive content (stop-hook I/O specs, the full bash script, safety mechanisms) that those references should hold is inlined in SKILL.md. This lands at anchor 3 ('content that should be separate is inline') and is held below 4 by the dangling reference and script paths.

Specificity

The description names the domain ('Hook installation and management for autonomous coding') with two concrete actions — installation and management — but 'management' is generic and it does not enumerate the specific operations the skill actually performs (install, remove, validate, check status). This matches anchor 3 ('names domain and 1-2 concrete actions, but not comprehensive'); score 4 would require several specific actions listed.

Completeness

It has an explicit 'Use when...' clause with concrete trigger phrases, and a 'what' ('Hook installation and management for autonomous coding'). However, the 'what' is thinner than anchor 5's example (which enumerates multiple concrete capabilities); 'installation and management' is high-level. This sits at anchor 4 — both present, with the 'what' lacking the specificity of a 5.

Trigger Term Quality

Phrases like 'setting up Stop hooks', 'managing pre/post tool hooks', and 'configuring autonomous continuation' are natural things a user managing Claude Code hooks would say. A few common variations are missing (e.g., 'install hooks', 'hook status', 'remove hooks' — which appear only in the frontmatter triggers, not the description), so it fits anchor 4 ('good keyword coverage; a few natural terms missing') rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The niche is clear — Claude Code hooks for autonomous operation, with distinct triggers like 'Stop hooks' and 'autonomous continuation' — so it is mostly distinct with only minor overlap risk against a generic Claude Code settings/configuration skill. It lacks the fully distinctive trigger set of anchor 5.
