Explore Tool

Answers how-does-X-work and flow questions in one MCP call, returning relevant symbols' source by file plus call paths between them.

Impact Analysis

Traces callers, callees, and the full impact radius of a symbol with codegraph callers, callees, and impact before you change it.

Affected Test Detection

Follows import dependencies from changed files to the test files they affect, for piping git diff output into a test runner in CI.

Automatic Index Sync

Watches source files with native OS events and re-indexes after a short debounce, flagging pending files so agents never read stale data.
