Conciseness

The bulk is lean and operational — command invocations plus flag tables with defaults, no explanations of concepts Claude already knows. Not a 5 because a few passages could be trimmed: the dense watch-mode paragraph ("MCP checks are throttled to once every five seconds, so a tool call before the next check can briefly use the previous index") and the npm 11.x workaround aside carry edge-case detail beyond the skill's core task.

Actionability

Every command is copy-paste ready ("node .gitnexus/run.cjs analyze") and flags come with defaults and effects in tables ("--debounce <ms>", "default: 300 ms"). This matches the anchor for fully executable, copy-paste-ready commands covering the common cases; nothing is pseudocode or vague.

Workflow Clarity

There is a clear "When to run" cue and an "After Indexing" checklist with a verify step ("Read gitnexus://repo/{name}/context to verify the index loaded") plus a Troubleshooting section. However, `clean` is a destructive and batch-capable operation ("Deletes the .gitnexus/ directory and unregisters the repo", `--all` cleans every indexed repo, `--force` skips confirmation) with no validation step before or after, which caps this dimension at 3 per the destructive/batch-operation rule.

Progressive Disclosure

No bundle files exist, and the single body is well organized into per-command sections, storage/retention, after-indexing, and troubleshooting — matching 'Good structure; most content is appropriately placed'. Not a 5 because deep operational detail (watch-mode semantics, the Spring Actuator/AsyncAPI enrichment paragraphs, wiki provider matrix) is inlined where a reference file would keep the overview shorter.

Specificity

The description lists five concrete actions — "analyze/index a repo, check status, clean the index, generate a wiki, or list indexed repos" — which comprehensively covers the skill's command surface. This matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage'; it is not the level below because no action named is generic.

Completeness

It explicitly answers both questions: 'what' is running GitNexus CLI commands (analyze, status, clean, wiki, list) and 'when' is an explicit "Use when the user needs to run GitNexus CLI commands like..." clause with concrete trigger phrases. This matches the anchor for a clear and explicit what AND when.

Trigger Term Quality

It supplies natural example utterances users would actually say — "Index this repo", "Reanalyze the codebase", "Generate a wiki" — plus command keywords. Not a 5: common variations such as "re-index", "reindex the codebase", or "generate docs/documentation" are missing.

Distinctiveness Conflict Risk

The niche is clear — everything is scoped to the named tool "GitNexus CLI" — giving mostly distinct triggers. Not a 5: phrases like "Reanalyze the codebase" and "Generate a wiki" are generic enough to compete with other GitNexus skills (exploring, debugging) or general documentation-generation skills.
