name: gitnexus-guide description: "Use when the user asks about GitNexus itself — available CLI commands, how to query the knowledge graph, graph schema, or workflow reference. Examples: "What GitNexus tools are available?", "How do I use GitNexus?""

GitNexus Guide

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.

Quick reference for all GitNexus CLI commands and the knowledge graph schema.

Always Start Here

For any task involving code understanding, debugging, impact analysis, or refactoring:

Run gitnexus status — check index freshness
Match your task to a skill below and read that skill file
Follow the skill's workflow and checklist

If step 1 warns the index is stale, run gitnexus analyze in the terminal first.

CLI Commands Reference

All commands are run directly via the Bash tool. Do not use mcpl or npx.

Command	What it gives you	Example
`gitnexus query "<concept>" --repo <name>`	Process-grouped code intelligence — execution flows related to a concept	`gitnexus query "auth flow" --repo <name>`
`gitnexus context "<symbol>" --repo <name>`	360-degree symbol view — categorized refs, processes it participates in	`gitnexus context "validateUser" --repo <name>`
`gitnexus impact "<symbol>" --direction upstream --repo <name>`	Symbol blast radius — what breaks at depth 1/2/3 with confidence	`gitnexus impact "myFunc" --direction upstream --repo <name>`
`gitnexus detect-changes --repo <name>`	Git-diff impact — what do your current changes affect	`gitnexus detect-changes --repo <name>`
`gitnexus rename "<old>" "<new>" --repo <name>`	Multi-file coordinated rename with confidence-tagged edits	`gitnexus rename "myFunc" "myNewFunc" --repo <name> --dry-run`
`gitnexus cypher "<query>" --repo <name>`	Raw graph queries	`gitnexus cypher "MATCH ..." --repo <name>`
`gitnexus status`	Index freshness check	`gitnexus status`
`gitnexus analyze`	Build or refresh the index	`gitnexus analyze`
`gitnexus list`	Discover indexed repos	`gitnexus list`
