gitnexus-cli - SKILL.md Agent Skill

name: gitnexus-cli description: "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""

GitNexus CLI Commands

IMPORTANT — How to use GitNexus: GitNexus is a standalone CLI tool. Run it directly via gitnexus <command> in the Bash tool. Do NOT use mcpl call gitnexus ... or npx gitnexus ... — gitnexus is installed globally and invoked by name.

Multi-repo note: Always pass --repo <name> to every command that operates on a specific repo to avoid "multiple repositories" errors.

All commands are run directly via the Bash tool — no npx or mcpl needed.

Commands

analyze — Build or refresh the index

gitnexus 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.

Flag	Effect
`--force`	Force full re-index even if up to date
`--embeddings`	Enable embedding generation for semantic search (off by default)

When to run: First time in a project, after major code changes, or when gitnexus status reports the index is stale. In Claude Code, a PostToolUse hook runs analyze automatically after git commit and git merge, preserving embeddings if previously generated.

status — Check index freshness

gitnexus 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

gitnexus 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.

Flag	Effect
`--force`	Skip confirmation prompt
`--all`	Clean all indexed repos, not just the current one

wiki — Generate documentation from the graph

gitnexus wiki

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

Flag	Effect
`--force`	Force full regeneration
`--model <model>`	LLM model (default: minimax/minimax-m2.5)
`--base-url <url>`	LLM API base URL
`--api-key <key>`	LLM API key
`--concurrency <n>`	Parallel LLM calls (default: 3)
`--gist`	Publish wiki as a public GitHub Gist

list — Show all indexed repos

gitnexus list

Lists all repositories registered in ~/.gitnexus/registry.json.

After Indexing

Run gitnexus status to verify the index loaded
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 context
Embeddings slow: Omit --embeddings (it's off by default) or set OPENAI_API_KEY for faster API-based embedding
