windows-compat
Audit and harden this Rust repo (code-graph-mcp) for Windows correctness: path-spelling drift between producers, the 32,767-char command-line cap, index-key mismatches, and path predicates that assume one ecosystem's layout. Use whenever touching code that builds, compares, prints, or stores a filesystem path; that spawns a process with a variable number of arguments (rg, git); that matches an executable name; or that classifies files by path shape — and whenever triaging a bug that reproduces only on Windows, reviewing a diff that touches path handling, or adding a predicate that has a SQL mirror. Reach for it even when the change looks small and nobody mentioned Windows: every defect in its catalogue shipped past a green CI matrix that already included windows-latest.
explore
Understand code structure efficiently using the AST index. Use BEFORE reading files one by one — when starting work in unfamiliar code, exploring a module before changes, or finding the right file to edit. One overview call replaces 5+ Read calls and saves significant context.
index
Diagnose and fix code-graph index issues. Use when: search returns unexpected/empty results, or after major codebase restructuring. Covers the health check and both rebuild paths from the CLI.
