Lists multiple specific concrete actions: writing atomic commits, splitting work into coherent commits, and reviewing whether a commit is too broad. These are distinct, actionable capabilities.

Clearly answers both what ('Write atomic, repo-style git commits from a change summary or diff') and when ('Use when preparing commit messages, splitting work into coherent commits, or reviewing whether a commit is too broad').

Includes strong natural trigger terms users would say: 'git commits', 'commit messages', 'diff', 'change summary', 'splitting work', 'atomic'. These cover common variations of how users discuss commit-related tasks.

Clearly scoped to git commit authoring with specific triggers like 'atomic commits', 'splitting work into commits', and 'commit too broad'. This is a well-defined niche unlikely to conflict with general code review or git workflow skills.

The skill is mostly efficient and avoids explaining things Claude already knows (like what git is), but some sections are slightly verbose—e.g., the 'Inputs' section listing four bullet points of obvious input types, and the procedure steps could be tightened. The anti-patterns list and context-file gating section add useful but somewhat wordy guidance.

The skill provides concrete, specific guidance: exact commit message format patterns, specific imperative verbs to use, clear rules for when to add body text, explicit file path patterns to check (context/plans/*.md), and specific anti-patterns to avoid. While there are no code examples per se, this is an instruction-only skill where the guidance is highly actionable and copy-paste ready for commit message formatting.

The 7-step procedure is clearly sequenced with logical progression from analysis through validation. Step 5 includes an explicit feedback loop (stop and ask for clarification if plan diffs are ambiguous rather than inventing references). Step 7 provides validation checkpoints. The context-file guidance gating section adds an additional decision checkpoint. This is a non-destructive, proposal-only workflow, so the validation level is appropriate.

The content is well-organized with clear sections (Goal, Inputs, Output format, Procedure, Anti-patterns), but everything is in a single file with no references to external resources. For a skill of this length (~80 lines of content), some sections like the detailed procedure steps or the plan-update rules could potentially be split out. However, the inline organization is reasonable for the complexity level.
