Conciseness

The body is composed almost entirely of terse imperative directives with zero padding and no explanations of concepts Claude already knows — no 'what a registry is' or library tutorials — so every token earns its place per the 5 anchor.

Actionability

Copy-paste-ready launcher commands for bash and PowerShell with exact flags, concrete follow-up subcommands (page/inspect/explain/details, sources list/enable/disable, packs), and explicit exit codes (0/2/3/4) cover the common cases fully, matching the 'fully executable' anchor.

Workflow Clarity

The search workflow (steps 1–8) and install workflow (steps 1–5) are clearly sequenced with explicit validation checkpoints: prerequisite check before run, inspect-before-install, explicit approval immediately before executing, and exit-code-driven error handling ('On prerequisite failure (exit 4), show the concise error and stop').

Progressive Disclosure

The three reference files (configuration.md, result-schema.md, architecture.md) exist, are linked one level deep, and are clearly signaled with their purpose. It falls short of 5 because dense inlined material — the 70/20/10 ranking formula and the footer/link contract rules — reads like reference content that could be split out of the overview.

Specificity

The description lists multiple concrete actions — 'Find and compare agent skills', 'list, enable, or disable those sources', 'Return broad, deterministic, provenance-rich discovery results, then verify a selected result on demand' — covering the skill's capabilities comprehensively, matching the 'multiple specific concrete actions; comprehensive coverage' anchor rather than the 'minor gaps' anchor at 4.

Completeness

Both 'what' and 'when' are explicit: capabilities plus 'Use for discovery and source management, never publishing or silently installing code.' The 'when' clause is present but abstract rather than the concrete trigger phrases ('when the user mentions X') required by the 5 anchor, while clearly above the 'weakly implied when' of the 3 anchor.

Trigger Term Quality

Natural terms like 'agent skills', 'find', 'compare', 'registries', 'GitHub repositories', and 'enable or disable' are present, giving good keyword coverage. It falls short of the 5 anchor because common user phrasings like 'search for skills', 'locate', or 'browse' are missing.

Distinctiveness Conflict Risk

It carves a clear niche (federated skill discovery and source management) and explicitly bounds it with 'never publishing or silently installing code', minimizing overlap with installer or generic search skills.
