nw-hotspot SKILL.md skillA
nw-hotspot from nwave-ai/nwave is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nwave-ai/nwave/nw-hotspot@git:20260320.d98f3cbPins git:20260320.d98f3cb in mdr.lock. Pin the fingerprint instead.

Git change frequency hotspot analysis — find the most-changed files in your codebase.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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

How to install
mdr add nwave-ai/nwave/nw-hotspot@sha256:4383f6f08861ac87The line at the top of this page pins the label git:20260320.d98f3cb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
