Conciseness

The body includes content Claude already knows, e.g. the porcelain status-indicator table ("`M `: Modified (staged)", "`??`: Untracked") and repeats the full output JSON schema verbatim across all three examples. It is mostly efficient and free of concept explanations, but these repeated blocks could be tightened, matching the score-3 anchor of "mostly efficient but includes some unnecessary explanation or could be trimmed" rather than the lean score-4/5 anchors.

Actionability

Quotes: exact input contract ("`gitStatusOutput`: String (raw output from `git status --porcelain`...)"), branch patterns ("`## branch-name...origin/branch-name`"), a complete output schema, and three worked input/output examples. Guidance is concrete and executable for the common cases; the minor gap is that renames are listed ("`R `: Renamed (staged)") but the `old -> new` porcelain rename syntax is never given a parsing rule, keeping it below fully copy-paste-ready score 5.

Workflow Clarity

Quotes: a clearly sequenced four-step process ("Step 1: Receive Git Status Output" through "Step 4: Return Structured Data") with explicit error-recovery branches ("Invalid Git Output: Return error describing format issue", "Not a Git Repository", "Empty Output: Return clean status") and a closing validation checklist ("Parses branch information correctly", "Handles detached HEAD state"). This is a simple read-only parsing skill (no destructive/batch operations, so the cap of 3 does not apply), and the single transformation is unambiguous with feedback paths, matching the score-5 anchor.

Progressive Disclosure

Quotes: well-organized sections ("## When to Use", "## Instructions", "## Error Handling", "## Examples", "## Validation") and an explicit statement "Supporting Files: None required - pure parsing logic." Structure is good and nothing misleadingly references missing files, but at ~160 lines the three full-JSON examples inflate the core file where one full example plus abbreviated edge-case outputs would suffice — a minor organization gap versus the ideally split score-5 structure.

Specificity

Quotes: "Parse git status output into structured data showing staged, modified, and untracked files" — names the domain and enumerates concrete output categories (staged, modified, untracked), which is more than the 1-2 actions of a score-3 anchor but omits deleted/renamed handling, leaving minor coverage gaps versus a score-5 comprehensive listing.

Completeness

Quotes: what = "Parse git status output into structured data..." and when = "Use for pre-flight validation, checking clean working directory, or listing changed files before commits" — both are present and explicit, but "pre-flight validation" is workflow jargon rather than a user-spoken trigger phrase, so it does not fully match the score-5 anchor's concrete user-facing triggers.

Trigger Term Quality

Quotes: "pre-flight validation, checking clean working directory, or listing changed files before commits" — several natural phrases users would say, plus "git status" itself, but common variants like "uncommitted changes" and "working tree" are missing, so it falls just short of the score-5 synonym-complete anchor.

Distinctiveness Conflict Risk

Quotes: "Parse git status output into structured data" — a clear niche (porcelain/status parsing) with distinct triggers (clean working directory, changed files before commits) that would not naturally fire a commit-message or diff-analysis skill; minimal conflict risk.
