Conciseness

The body is lean and imperative throughout — no explanations of git concepts Claude already knows, and every instruction is operational. It falls short of 5 only because guardrails are repeated across sections ('do not stage' appears in Input, both workflow paths, and Rules again; 'Do not run git commit' is stated twice) and the generic 10-line 'Execution contract' preamble could be trimmed.

Actionability

Guidance is fully executable: an exact command with exit-code semantics ('Run `git diff --cached --quiet`. A zero exit status means nothing is staged.'), precise mode-token parsing rules (exact case-insensitive first-token match, everything else is commit context), explicit branch conditions on named statuses (blocked/proposal/bypass_message), and named output layouts per terminal state. An agent can execute the entire workflow with no invented steps; the reference files carry the remaining concrete commands.

Workflow Clarity

Both paths are strictly sequenced with numbered steps, explicit stops, and validation checkpoints at every risky point: a user-confirmation staging gate before the phase, a staged-content check before any bypass work, status-based branching with a defined contract-violation handler (proposal in bypass mode), and distinct failure/success layouts after the commit handoff. The destructive operation (git commit) is wrapped in validation and explicit failure handling, so the missing-validation cap does not apply.

Progressive Disclosure

SKILL.md is a clean control-flow overview that appropriately delegates the phase (atomic-commit.md) and all user-visible layouts (output.md) to well-signaled, one-level references, each referenced by exact path and read-timing instruction. It falls short of 5 because the third bundle file, references/commit-message-style.md, is never surfaced from SKILL.md — it is only reachable through atomic-commit.md, making that chain two levels deep, which the 5 anchor's one-level-deep criterion excludes.

Specificity

The description names the domain ("staged changes", "commit workflow") and two concrete actions ("Analyze staged changes", "run the regular or explicit bypass commit workflow"), but stops there — it never mentions writing or splitting commit messages, proposing commits, or the one-commit-per-invocation behavior. This matches the anchor for naming a domain with 1-2 concrete actions without comprehensive coverage; a 4 would require several specific actions with only minor gaps.

Completeness

The 'what' is clear (analyze staged changes, run a regular or bypass commit workflow), but there is no 'Use when...' clause or any equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. A 4 would require an explicit — even if imperfect — 'when' statement.

Trigger Term Quality

It contains a few relevant natural terms ("commit", "staged changes", "bypass"), but misses common variations users would actually say — "commit message", "git commit", "atomic commits", the `oneshot`/`skip` tokens, or any extension cues. Some relevant keywords but missing common variations and synonyms places it at the middle anchor rather than 4's good keyword coverage.

Distinctiveness Conflict Risk

The capability described is a specific niche (staged-changes-only atomic commit workflow with a distinct regular/bypass split), giving it minor overlap risk only with closely related generic commit helpers. It falls short of a 5 because the absence of any trigger phrases means a generic 'commit my changes' request has no distinguishing signal pointing to this skill over a sibling commit skill.
