Starlark — 18 Operations for AI Agents

Starlark is the language of build logic at scale — Bazel macros, Buck rules, the Python-shaped layer that decides what compiles. act101 reads rules and macros as structure, so agents navigate build definitions instead of reverse-engineering them.

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