Ninja — 18 Operations for AI Agents

Ninja files are the generated build graph beneath CMake, GN, and Meson. act101 reads rules and build edges as structure, so agents debug build dependencies without untangling machine-written output by hand.

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Ninja code through the act MCP server. 18 operations available: 0 refactor, 18 query, 0 analysis. Each operation is callable from Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent host. Click any operation for a stable anchor link suitable for citation.

Query

18 query tools, the same on every supported language. Descriptions live in the shared reference: /docs/query-tools.
