Settle data shapes, ownership, boundaries, and interfaces before code crosses a function/module boundary. Use for non-trivial design work.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Architect
Read the caller first. Architecture starts from use, not from an isolated abstraction.
1. Name the domain data shape and invariants.
2. Map ownership and lifecycle. For concurrency, identify what is truly shared before proposing synchronization.
3. Draft 2-3 boundary shapes when the decision is contested. If `delegate` is available, assign independent designs; otherwise keep alternatives explicit and sequential.
4. Compare on reader load, invalid states, migration cost, idempotence, testability, and fit with existing architecture.
5. Select the smallest coherent shape and write the caller-facing signature/contract before implementation.
6. Use `interrogate` for high-risk or contested decisions.
The line at the top of this page pins the label git:20260908.ec65ed5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
