mdr add tamnguyendinh/anvien/anvien-debugging@git:20260529.973b8f5Pins git:20260529.973b8f5 in mdr.lock. Pin the fingerprint instead.

Use when the user is debugging a bug, tracing an error, or asking why something fails. Examples: "Why is X failing?", "Where does this error come from?", "Trace this bug".
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
# Debugging with Anvien
## When to Use
- "Why is this function failing?"
- "Trace where this error comes from"
- "Who calls this method?"
- "This endpoint returns 500"
- Investigating bugs, errors, or unexpected behavior
## Workflow
```
1. query({query: "<error or symptom>"}) → Find related execution flows
2. context({name: "<suspect>"}) → See callers/callees/processes
3. READ anvien://repo/{name}/process/{name} → Trace execution flow
4. cypher({query: "MATCH path..."}) → Custom traces if needed
```
> If "Index is stale" → run `anvien analyze` in terminal.
## Checklist
```
- [ ] Understand the symptom (error message, unexpected behavior)
- [ ] query for error text or related code
- [ ] Identify the suspect function from returned processes
- [ ] context to see callers and callees
- [ ] Trace execution flow via process resource if applicable
- [ ] cypher for custom call chain traces if needed
- [ ] Read source files to confirm root cause
```
## Debugging Patterns

How to install
mdr add tamnguyendinh/anvien/anvien-debugging@sha256:2a7325a668bfcac1The line at the top of this page pins the label git:20260529.973b8f5, 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.
