gitnexus-debugging SKILL.md skillA
gitnexus-debugging from metagit-ai/metagit-cli is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add metagit-ai/metagit-cli/gitnexus-debugging@git:20260907.a6ce61cPins git:20260907.a6ce61c 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 GitNexus
## 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
## Bind the repository first
A root cause traced in the wrong repository is a wrong root cause.
Call `list_repos {}` before the first tool call. With one indexed repository,
use the examples below as written. With more than one, pass `repo` on every
call: an omitted `repo` normally errors, but under an MCP policy with a
configured default it resolves to that default silently. If you cannot tell
which repository is meant, stop and ask. This matters most for `cypher`, whose
statement carries no in-band hint of which database it ran against.
`list_repos` is paginated, so page with `offset: pagination.nextOffset` until
`hasMore` is false before concluding a repository is absent.
A stale index describes the code from before your bug, so refresh before
trusting a trace, and state the repository and index freshness with the
diagnosis.
## Workflow
```
0. list_repos {} → Bind repo
…Read the whole file at its exact version.
How to install
mdr add metagit-ai/metagit-cli/gitnexus-debugging@sha256:cd215459b252b6bcThe line at the top of this page pins the label git:20260907.a6ce61c, 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.
