The body is lean and avoids explaining concepts Claude already knows, but the 'Common Mistakes' and 'Red Flags' sections overlap substantially (both cover providing context, verifying, and avoiding trivial updates) and could be consolidated.

Checklists, an exact subagent type, 'git status', and a copy-paste format template are concrete, but the central dispatch is shown as 'Task(subagent_type: nori-change-documenter)' inside a bash block, which is non-executable pseudocode rather than the real tool-call form.

A clear three-step sequence (Gather Context -> Dispatch -> Verify) with Step 3 as an explicit verification checkpoint and per-step checklists provides the validation/feedback loop the rubric rewards.

The skill is self-contained with no bundle files, well-organized into clearly labeled sections, and contains no nested references; the inline format template is core content that belongs in SKILL.md.

Names the domain ('documentation') and one action ('update') but does not list multiple concrete actions like gather context, dispatch subagent, and verify; not vague enough for 1, not comprehensive enough for 3.

Opens with an explicit 'Use this when...' trigger and states what it does ('update the documentation based on those changes'), clearly answering both what and when.

'finished making code changes' and 'update the documentation' are natural phrasings, but it lacks common variations a user might say such as 'docs', 'after coding', or 'document the changes'.

The post-code-change doc-update trigger is a fairly distinct niche, but the generic term 'documentation' could still overlap with other general documentation skills.
