Conciseness

Mostly functional content (concrete CLI command, parameter tables, schemas, troubleshooting) but with clear duplication that could be tightened: the parameters are documented twice ('## Inputs' bullet list and '## Input' table), the result shape is described twice ('## Result composition' and the Output JSON Schema), and the intro paragraph repeats the frontmatter description almost verbatim. This fits anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened') rather than 2, since there is no explanation of concepts Claude already knows and no padded prose — the issue is redundancy, not verbosity throughout.

Actionability

The '## How to Call' section gives a copy-paste-ready `unity-mcp-cli run-tool package-search` command plus working alternatives (--input-file, stdin heredoc) and a concrete troubleshooting path ('If `unity-mcp-cli` is not found... npm install -g unity-mcp-cli or use npx'). It falls short of anchor 5 because the primary example uses placeholder values ('"query": "string_value", "maxResults": 0') rather than a realistic example query like 'com.unity.textmeshpro', though the Input table does supply real example values.

Workflow Clarity

For this single-action tool skill, the call procedure is unambiguous: one command with a documented fallback (input-file/stdin) and an explicit error-recovery branch for a missing CLI (install globally or use npx), which serves as a feedback loop. It sits at anchor 4 rather than 5 because there is no guidance for interpreting failure/empty results (e.g., what to do when the search returns nothing or offlineMode finds no match), leaving a minor validation gap in the workflow.

Progressive Disclosure

Sections are clearly headed and the one external pointer ('Read the /unity-initial-setup skill') is plainly signaled, but the ~90 lines of inline Input/Output JSON schemas are bulk reference material that belongs in a separate reference file, and no bundle files exist to offload it. This matches anchor 3 ('some structure but could be better organized; content that should be separate is inline') — not 2, because the document is navigable with clear headers rather than a monolithic wall, and not 4, because the bulky schemas are not split out.

Specificity

Concrete actions are stated in third person — 'Search Unity's package registry plus locally installed packages (Git, local, embedded sources) by query string. Returns available versions and installation status. Online mode fetches exact matches from the live registry then supplements with cached substring matches.' It names several specific behaviors (registry + local search, returned data, online/offline modes) with only minor gaps (no mention of match prioritization that appears in the body). It is above anchor 3 ('1-2 concrete actions') because multiple distinct actions and behaviors are covered, but below anchor 5 because coverage is not comprehensive — e.g., the query matching/prioritization rules are omitted.

Completeness

The 'what' is clear and concrete (search registry and installed packages by query string, return versions and install status), but the 'when' is entirely absent — there is no 'Use when...' clause or equivalent explicit trigger guidance, which per the judging guidelines caps completeness at 3. It is not 4 because 'when' is not even weakly implied by any trigger phrase, and not 2 because the 'what' is specific and detailed rather than vague.

Trigger Term Quality

Includes natural terms users would say: 'Unity', 'package registry', 'packages', 'installed packages', 'query', 'versions'. Missing a few natural variations users commonly use, such as 'find', 'Package Manager', 'UPM', 'install', or package-id forms like 'com.unity.*' — so it fits anchor 4 ('good keyword coverage; a few natural terms missing') rather than anchor 5's comprehensive coverage with synonyms/extensions.

Distinctiveness Conflict Risk

The Unity package-registry niche is quite distinct ('Unity's package registry', 'locally installed packages (Git, local, embedded sources)'), so it would not trigger for unrelated skills. Minor overlap risk remains with closely related Unity package-management skills (e.g., an install/add-package skill) since shared terms like 'packages' and 'versions' are not disambiguated by an explicit trigger clause — fits anchor 4 rather than anchor 5.
