# Build Graph

Build or incrementally update the persistent code knowledge graph for this repository.

## Steps

1. **Check graph status** by calling the `list_graph_stats_tool` MCP tool.
   - If the graph has never been built (last_updated is null), proceed with a full build.
   - If the graph exists, proceed with an incremental update.

2. **Build the graph** by calling the `build_or_update_graph_tool` MCP tool:
   - For first-time setup: `build_or_update_graph_tool(full_rebuild=True)`
   - For updates: `build_or_update_graph_tool()` (incremental by default)

3. **Verify** by calling `list_graph_stats_tool` again and report the results:
   - Number of files parsed
   - Number of nodes and edges created
   - Languages detected
   - Any errors encountered

## When to Use

- First time setting up the graph for a repository
- After major refactoring or branch switches
- If the graph seems stale or out of sync
- The graph auto-updates via hooks on edit/commit, so manual builds are rarely needed

## Notes

- The graph is stored as a SQLite database (`.code-review-graph/graph.db`) in the repo root
- Binary files, generated files, and patterns in `.code-review-graphignore` are skipped
- Supported languages: Python, TypeScript/JavaScript, Vue, Go, Rust, Java, Scala, C#, Ruby, Kotlin, Swift, PHP, Solidity, C/C++
