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
## Bind the repository first
Impact analysis is the gate that authorizes an edit, so it must answer for the
repository you are about to edit.
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 — every result below an ambiguous
identity inherits the ambiguity. `list_repos` is paginated, so page with
`offset: pagination.nextOffset` until `hasMore` is false before concluding a
repository is absent.
`detect_changes` takes `worktree` when your changes are in a linked worktree
the MCP server was not launched from. The server auto-detects a worktree only

How to install
mdr add metagit-ai/metagit-cli/gitnexus-impact-analysis@sha256:594ccb8707c5fb72The 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.
