gitnexus-cli

Skill36 starsChanged 37 days agoApache-2.0View on GitHub

Use when the user needs to run GitNexus CLI commands like analyze/index a repo, check status, clean the index, generate a wiki, or list indexed repos. Examples: \"Index this repo\", \"Reanalyze the codebase\", \"Generate a wiki\"

  • Reads credentials
  • Installs packages

We split this skill into the rules it gives an agent

3 rules. 1 is common, 0 are distinctive, and 2 are very specific to this project.

  • 1

    Common

    Most of the 7 edited versions we read keep these.

  • 0

    Distinctive

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Run from the project root.

    line 20
  2. Very specific:

    Use the other GitNexus skills (exploring, debugging, impact-analysis, refactoring) for your task

    line 80
  3. Common:

    "Not inside a git repository": Run from a directory inside a git repo

    line 84

“Common” is measured: kept by at least 6 in 10 of the 7 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

GitNexus CLI Commands

Commands below use node .gitnexus/run.cjs <command> — the project-local runner gitnexus analyze drops next to the index. It auto-selects an available runner at call time (global gitnexus, else pnpm dlx, else bunx, else npx), so no package-manager assumption and no global install is required — including on a bun-only machine, which has no npm, npx or pnpm at all.

Not analyzed yet, or node .gitnexus/run.cjs reports Cannot find module (the gitignored runner is absent — e.g. a fresh clone or git clean)? (Re)generate it with npx gitnexus analyze from the project root, or bunx gitnexus@latest analyze on a bun-only machine. On npm 11.x, if npx crashes during install (node.target is null), install once with npm i -g gitnexus (then gitnexus analyze), or use bunx gitnexus@latest analyze, or pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyze. See #1939.

Commands

analyze — Build or refresh the index

node .gitnexus/run.cjs analyze

Run from the project root. This parses all source files, builds the knowledge graph, writes it to .gitnexus/, and generates CLAUDE.md / AGENTS.md context files.

FlagEffect
--forceForce full re-index even if up to date
--embeddingsEnable embedding generation for semantic search (off by default)
--drop-embeddingsDrop existing embeddings on rebuild. By default, an analyze without --embeddings preserves them.
--pdgBuild the program-dependence layers used by explain and pdg_query (taint, CDG, and REACHING_DEF).

When to run: First time in a project, after major code changes, or when gitnexus://repo/{name}/context reports the index is stale. In Claude Code, a PostToolUse hook detects staleness after git commit and git merge and notifies the agent to run analyze — the hook does not run analyze itself, to avoid blocking the agent for up to 120s and risking KuzuDB corruption on timeout.

status — Check index freshness

node .gitnexus/run.cjs status

Shows whether the current repo has a GitNexus index, when it was last updated, and symbol/relationship counts. Use this to check if re-indexing is needed.

clean — Delete the index

node .gitnexus/run.cjs clean

Deletes the .gitnexus/ directory and unregisters the repo from the global registry. Use before re-indexing if the index is corrupt or after removing GitNexus from a project.

FlagEffect
--forceSkip confirmation prompt
--allClean all indexed repos, not just the current one

wiki — Generate documentation from the graph

node .gitnexus/run.cjs wiki

Generates repository documentation from the knowledge graph using an LLM. Requires an API key (saved to ~/.gitnexus/config.json on first use).

FlagEffect
--forceForce full regeneration
--model <model>LLM model (default: MiniMax-M3)
--base-url <url>LLM API base URL
--api-key <key>LLM API key
--concurrency <n>Parallel LLM calls (default: 3)
--gistPublish wiki as a public GitHub Gist

list — Show all indexed repos

node .gitnexus/run.cjs list

Lists all repositories registered in ~/.gitnexus/registry.json. The MCP list_repos tool provides the same information.

After Indexing

  1. Read gitnexus://repo/{name}/context to verify the index loaded
  2. Use the other GitNexus skills (exploring, debugging, impact-analysis, refactoring) for your task

Troubleshooting

  • "Not inside a git repository": Run from a directory inside a git repo
  • Index is stale after re-analyzing: Restart Claude Code to reload the MCP server
  • Embeddings slow: Omit --embeddings (it's off by default) or set OPENAI_API_KEY for faster API-based embedding

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
