Conciseness

Every section is repo-specific contract Claude cannot infer — the sourced-module/exit semantics, the skip_unless usage rules (command vs. path vs. chained requirements vs. message format), exact registration positions ('among the source lines', 'positioned per the Order matters comment'), and the test flags. No section explains concepts Claude already knows, and nothing is padded.

Actionability

The guidance is fully executable: a copy-paste-ready install.sh template with the lib/skip.sh guard pattern, exact test commands ('bash mymodule/install.sh --non-interactive --overwrite --allow'), exact file paths (config.sh.example, bash/exports.sh, homebrew/bundle), and named reference modules for each pattern. The README spec bullets make step 2 concrete rather than vague.

Workflow Clarity

The numbered checklist gives a clear, correctly ordered sequence (create -> README -> install.sh -> register -> packages -> root README -> config) with an explicit validation section (test standalone, then via main installer). It falls short of anchor 5 only because the Testing section lacks an error-recovery feedback loop — there is no 'if the test fails, check X and re-run' guidance, only the commands themselves.

Progressive Disclosure

No bundle files exist, and none are needed at this size: the body is well-sectioned into When/Checklist/Template/Testing/References, with one-level-deep, clearly signaled pointers ('lib/skip.sh holds the full contract'; four reference modules each annotated with the pattern it demonstrates). All inline content earns its place at authoring time.

Specificity

The description names the domain ('dotfiles') but the only action is the generic 'adding new modules, configs, or tools' — no concrete actions like creating module directories, writing install scripts, or updating the root README are stated. It matches anchor 2 ('Names the domain but actions are minimal or generic'): it is more concrete than anchor 1's pure abstraction, but does not list the 1-2 concrete actions anchor 3 requires.

Completeness

The description is only a 'when' clause ('Use when adding...') with no 'what' — it never states what the skill does (guide the checklist for adding a module: directory, README, install.sh, registration, root README updates). This matches anchor 2's 'only when is present without what' exactly, as in 'Use when working with documents'.

Trigger Term Quality

'adding', 'modules', 'configs', 'tools', and 'dotfiles' are natural terms a user maintaining a dotfiles repo would say, giving good keyword coverage across the domain's variations. It falls short of anchor 5's comprehensive coverage because common phrasings like 'install', 'set up', or specific tool/package names are missing.

Distinctiveness Conflict Risk

The 'to dotfiles' qualifier establishes a clear niche that most skills would not match, but the generic nouns 'configs' and 'tools' carry minor overlap risk with closely related repo-maintenance or package-installation skills. This fits anchor 4 ('mostly distinct; minor overlap risk') rather than anchor 5's minimal-conflict clear niche with distinct triggers.
