Analyzes changesets with risk scoring, categorization by type and impact, and release note preparation. Use when extracting insights from raw change data.
npx skills add majiayu000/claude-skill-registry --skill diff-analysis-athola-claude-night-market-3 --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.

Works for git diffs, configuration changes, API migrations, schema updates, or document revisions. ## When To Use - Extracting insights from raw change data - Categorizing and prioritizing changes before code reviews - Preparing release notes or changelogs - Assessing migration scope and risk ## When NOT To Use - Quick context catchup - use catchup instead - Full PR review - use review-core with pensive skills ## Activation Patterns **Trigger Keywords**: diff, changes, release notes, changelog, migration, impact, risk assessment **Auto-Load When**: Git diffs present, change analysis requested, impact assessment needed. ## Progressive Loading Load modules based on workflow stage: ### Always Load - `modules/semantic-categorization.md` for change categorization workflow ### Conditional Loading - `modules/risk-assessment-framework.md` when risk assessment

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill diff-analysis-athola-claude-night-market-3 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
