The skill is mostly efficient but includes some unnecessary elaboration. For example, the 'Inputs' section and 'Goals' section restate things that are implicit from the steps. Some steps could be tightened (e.g., steps 4-5 overlap, and step 12 partially restates step 5). However, it doesn't explain basic concepts Claude already knows.

The skill provides concrete, specific guidance: exact git commands (`git add -A`, `git diff --staged`, `git commit -F <file>`), a complete commit message template, specific formatting rules (72 chars, imperative mood), and even the exact Co-authored-by trailer to use. The steps are directly executable.

The 12-step workflow is clearly sequenced with explicit validation checkpoints: step 4 flags suspicious files before committing, step 5 handles incomplete staging, and step 12 provides a final gate ensuring message-diff consistency before committing. This includes proper feedback loops for error recovery.

For a single-purpose skill under 50 lines with no need for external references, the content is well-organized into clear sections (Goals, Inputs, Steps, Output, Template). The structure is logical and easy to navigate without requiring additional files.

Names the domain (git commit) and some actions (create commit, use session history for rationale/summary), but doesn't list multiple distinct concrete actions like staging, amending, or formatting conventions.

Clearly answers both 'what' (create a well-formed git commit from current changes using session history) and 'when' (explicitly states 'use when asked to commit, prepare a commit message, or finalize staged work').

Includes strong natural trigger terms users would say: 'commit', 'prepare a commit message', 'finalize staged work', and 'git commit'. These cover common variations of how users request this task.

Clearly scoped to git commit creation with distinct triggers like 'commit message' and 'staged work'. The mention of using session history for rationale further distinguishes it from generic git or code skills.
