This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
gitnexus-impact-analysis from canvascoding/canvas-notebook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add canvascoding/canvas-notebook/gitnexus-impact-analysis@git:20260827.0c0ca99Pins git:20260827.0c0ca99 in mdr.lock. Pin the fingerprint instead.

Use when the user wants to know what will break if they change something, or needs safety analysis before editing code. Examples: "Is it safe to change X?", "What depends on this?", "What will break?".
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
# Impact Analysis with GitNexus
## When to Use
- "Is it safe to change this function?"
- "What will break if I modify X?"
- "Show me the blast radius"
- "Who uses this code?"
- Before making non-trivial code changes
- Before committing — to understand what your changes affect
## Workflow
```
1. impact({target: "X", direction: "upstream"}) → What depends on this
2. READ gitnexus://repo/{name}/processes → Check affected execution flows
3. detect_changes() → Map current git changes to affected flows
4. Assess risk and report to user
```
> If "Index is stale" → run `node .gitnexus/run.cjs analyze` in terminal.
## Checklist
```
- [ ] impact({target, direction: "upstream"}) to find dependents
- [ ] Review d=1 items first (these WILL BREAK)
- [ ] Check high-confidence (>0.8) dependencies
- [ ] READ processes to check affected execution flows
- [ ] detect_changes() for pre-commit check
- [ ] Assess risk level and report to user
```
## Understanding Output
| Depth | Risk Level | Meaning |
| ----- | ---------------- | ------------------------ |
| d=1 | **WILL BREAK** | Direct callers/importers |

How to install
mdr add canvascoding/canvas-notebook/gitnexus-impact-analysis@sha256:09e529505da15553The line at the top of this page pins the label git:20260827.0c0ca99, 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.
