Conciseness

The body is directive throughout with no concept-explanation padding, but the same guardrails are repeated: "Read `references/atomic-commit.md` before running the phase" appears in the Phase reference, in both workflow paths, and again in Rules, and the Rules section restates prohibitions already stated inline ("Do not stage, unstage, restore, or otherwise modify repository or worktree files"). This is anchor 3 (mostly efficient but could be tightened) rather than 4, where only minor trims would be needed.

Actionability

The guidance is fully executable for an instruction-only skill: exact commands with exit-status semantics ("Run `git diff --cached --quiet`. A zero exit status means nothing is staged"), precise input parsing ("exactly `oneshot` or `skip`, compared case-insensitively"), explicit branch conditions on `status` values, and named output layouts. There are no vague steps; each action specifies what to run, what to check, and where to stop.

Workflow Clarity

Both paths are clearly sequenced with explicit validation checkpoints: the regular path gates on a user-confirmed staging prompt ("stop and prompt the user with the Regular-mode staging gate"), the bypass path validates staged content before proceeding, `status` branches are enumerated with defined stops, and failure handling is explicit ("Do not proceed past a failed `git commit`", "On failure, render the Bypass Git failure layout ... and stop"). This matches anchor 5's clear sequence with explicit validation and defined error handling.

Progressive Disclosure

The split is well designed — SKILL.md holds control flow ("This document holds the control flow ... the reference holds the phase itself") with phase details in `references/atomic-commit.md` and all layouts in `references/output.md`, both real files, clearly signaled, and read-order guidance is given. However `references/commit-message-style.md` is only reachable through `atomic-commit.md`, making the reference chain two levels deep; that minor organization gap holds this at anchor 4 rather than 5 ("one-level-deep references").

Specificity

"Analyze staged changes and run the regular or explicit bypass commit workflow" names the domain (staged changes, commits) and two actions (analyze, run workflow), but does not list what the workflow produces (commit messages, split proposals). This matches anchor 3 (domain plus 1-2 concrete actions); it falls short of anchor 4, which requires several specific actions.

Completeness

The "what" is clear (analyze staged changes, run a commit workflow in regular or bypass mode), but there is no "when" or equivalent trigger guidance anywhere in the description. Per the judging guidelines, a missing "Use when..." clause caps completeness at 3.

Trigger Term Quality

"staged changes", "commit", and "bypass" are natural user terms, but common trigger phrases such as "commit message", "atomic commit", or the mode tokens themselves ("oneshot", "skip") are absent. This sits at anchor 3 (some relevant keywords, missing common variations) rather than 4.

Distinctiveness Conflict Risk

"regular or explicit bypass commit workflow" gives it a niche, but "Analyze staged changes" overlaps heavily with generic commit-message and git-helper skills. Anchor 3 (somewhat specific, could still overlap with similar skills) fits better than 4 because the distinguishing modes are only weakly surfaced.
