Use the Agent Buildprint at /buildprints/buildprint-mapper-os/agent.md. Fetch /buildprints/buildprint-mapper-os/package.json. Read order: `BUILDPRINT.md`. Do not scrape human cards. Use this manifest, agent.md, and raw files. BUILDPRINT.md is the canonical start file and owns the required read order, phase gates, and acceptance gates. Structured control files are machine-readable mirrors only. Follow alignment/question rules before implementation. Do not scrape human UI cards. If the Buildprint requires it, finish with a chat handover summarizing outcome, evidence, known gaps, and recommended next direction. Use the Buildprint Mapper OS Buildprint to map a target repo in the current agent session. First bootstrap exact snapshots: agb start https://agent-buildprint.com/buildprints/buildprint-mapper-os/package.json . If agb is not installed, clone https://github.com/DomEscobar/agent-buildprint and run node agent-buildprint/bin/agb.js start https://agent-buildprint.com/buildprints/buildprint-mapper-os/package.json . Then read .buildprint/next-agent.md and continue. Do not write Buildprint snapshots manually. Before discovery, resolve the target: if no repository URL, local path, or already-opened working repo is given, ask exactly one blocking question — 'Which repo URL or local path should I map?' — and do not start until it is explicit.
