Git change frequency hotspot analysis — find the most-changed files in your codebase
npx skills add majiayu000/claude-skill-registry --skill nw-hotspot --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.
# NW-HOTSPOT: Code Crime Scene Hotspot Lens **Wave**: CROSS_WAVE **Execution**: Inline (no agent — Claude executes git commands directly) **Inspiration**: Adam Tornhill's "Your Code as a Crime Scene" ## Overview Analyze git change frequency to identify the most-changed files in a codebase. Pure git churn — no complexity metrics. Use as a **pre-filter** to scope analysis or a **post-filter** to prioritize existing findings. ## How It Works Run `git log --name-only` over the configured time period, count commits per file, rank by frequency. ## Modes ### 1. Analyze (default) Show the most-changed files in the repo. Output is inline only — no files persisted. ``` /nw-hotspot /nw-hotspot --top=20 /nw-hotspot --since=12m ``` **Steps:** 1. Run: `git log --since={since} --format=format: --name-only | sort | uniq -c | sort -rn` 2. Exclude deleted files (verify each file still exists with `test -f`) 3. For each file, get last changed date: `git log -1 --format="%ar" -- {file}` 4. Display ranked table (top N): ``` Rank │ Commits │ Last Changed │ File ──────┼─────────┼──────────────┼───────────────────────── 1 │ 87 │ 2 days ago │ src/services/payment.ts 2 │ 64 │ 1 week ago │ src/api/controller

What does the nw-hotspot skill do?
Git change frequency hotspot analysis — find the most-changed files in your codebase
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill nw-hotspot --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.
