Conciseness

The 70-line body is dense with skill-specific information Claude cannot know (script signatures, repo-root validation, exclude pathspec magic, GIT_SKILL_DEBUG, non-interactive flags) and avoids teaching general git concepts. A few passages run longer than needed — the multi-sentence rationale for passing the repo root explicitly, and the bold-heavy excludes/debug paragraph — so anchor 4 (efficient, minor trimming possible) fits better than anchor 5.

Actionability

Every script is given as a copy-paste-ready invocation with argument signatures, a concrete example call ("scripts/git-diff.sh /path/to/repo main"), an anti-pattern note, a debug command ("GIT_SKILL_DEBUG=1 scripts/git-cached-diff.sh /path/to/repo"), and executable error-handling commands ("git -C <repo-root> rev-parse --git-dir", "chmod +x scripts/*.sh"). This matches anchor 5: fully executable commands covering the common cases; verified against the actual scripts (common.sh does provide parse_repo_root, build_exclude_args, GIT_SKILL_DEBUG, GIT_TERMINAL_PROMPT handling).

Workflow Clarity

The five operations are numbered and sequenced, each with a required reference file to read before starting, and an Error Handling section provides a diagnostic feedback loop. Validation checkpoints for the batch auto-commit operation exist but live in the delegated reference (auto_commit_workflow.md's confirm-staged and abort steps) rather than the main body, and the body's own per-operation checkpoints are implicit ('read the reference file first'), so anchor 4 (clear sequence, most checkpoints present, minor gaps) fits better than anchor 5.

Progressive Disclosure

The body is a lean overview and the bulk of the content (729 lines across 8 reference files) is split into one-level-deep, well-signaled references — every referenced path exists in the bundle, each operation names its reference file(s) explicitly, and paths are declared relative to the skill directory. Cross-links between references (e.g., op_review → guidelines, auto_commit → partial_staging) are supplementary; all files remain directly discoverable from SKILL.md, matching anchor 5's clear overview with easy navigation.

Specificity

The description names the domain ("git-related request") and enumerates several task areas ("commit messages, staging review, history, PR descriptions"), but these read as request categories rather than the concrete actions the skill performs (e.g., generating commit messages, composing PR bodies, auto-committing grouped changes). It matches anchor 3 (domain plus some concrete items, not comprehensive) better than anchor 4, which expects explicit specific actions.

Completeness

The 'when' is explicit and strong ("Always invoke this skill for any git-related request"), and a 'what' is present but only implied via the parenthetical list and the vague purpose clause "so git workflows are handled consistently". This fits anchor 4 (both what and when present, one could be more explicit) rather than anchor 5, which requires a concrete action statement alongside the trigger.

Trigger Term Quality

Natural phrases users would say are present — "commit messages", "PR descriptions", "git", "staging review", "history" — giving good keyword coverage. A few common variations are missing (e.g., "diff", "pull request" spelled out, "changelog"), so it falls just short of anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The git-workflow domain itself is reasonably distinct, but the absolute trigger ("Always invoke this skill for any git-related request ... etc.") maximizes overlap with adjacent single-purpose skills (commit-message generators, code-review, PR-creation skills). Somewhat specific yet with real overlap risk matches anchor 3; it is not anchor 2's fully generic case, but broader than anchor 4's minor-overlap profile.
