SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides a concise reference and onboarding path for developers who need to use GitNexus tools, query the project knowledge graph, and select the correct MCP workflow so they can quickly locate code context, run impact analyses, and perform refactors or debugging with confidence.

Core Features & Use Cases

  • Tool reference: Summarizes available GitNexus tools and what each one returns (query, context, impact, detect_changes, rename, cypher).
  • Resource navigation: Explains key repository endpoints and lightweight reads for repo context, clusters, processes, and schema lookups.
  • Workflow guidance: Prescribes the recommended sequence (check context/index freshness, choose the matching skill, follow skill checklist) for tasks like architecture exploration, blast radius analysis, bug tracing, and refactoring.
  • Use case example: When preparing a rename across a large codebase, check repository context for index staleness, run impact queries to identify breakage risk, and then use the rename workflow to coordinate changes.

Quick Start

Read the repository context to confirm index freshness, then pick the appropriate GitNexus tool for your task and follow its checklist.

Frequently Asked Questions about gitnexus-guide

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I query a project knowledge graph for code context during refactoring?▼

Query the project knowledge graph by selecting the appropriate GitNexus MCP tool, checking repository context for index freshness, and running impact queries to identify breakage risk before refactoring.

What's the best way to run impact analysis across an indexed repository?▼

Run impact analysis by first confirming repository index freshness through resource endpoints, then applying the blast radius analysis workflow to map breakage risks using the designated MCP query patterns.

How do I trace bugs using graph schema lookups in an indexed codebase?▼

Trace bugs by navigating repository endpoints for schema lookups, verifying index freshness, and following the bug tracing workflow checklist to execute targeted queries within the indexed repositories.

Can I use MCP tools to coordinate a large-scale rename across a codebase?▼

Yes, you can use MCP tools for renaming by checking repository context for staleness, running impact queries to assess blast radius, and following the rename workflow checklist to coordinate changes safely.

When should I check index freshness before querying the knowledge graph?▼

Check index freshness before querying the knowledge graph whenever preparing tasks like architecture exploration or refactoring, ensuring repository context endpoints confirm the index is current before executing MCP queries.

Does GitNexus query tooling work with Cypher for complex graph queries?▼

GitNexus provides a Cypher tool among its available MCP query tools, allowing you to execute common query patterns directly against the project knowledge graph within indexed repositories.
