GN — 18 Operations for AI Agents

GN files generate the build behind Chromium-scale projects — targets, deps, and configs across thousands of directories. act101 reads those declarations structurally, so agents trace a build target through the tree without grep archaeology.

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze GN 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.
