architecture SKILL.md skillA
architecture from sd0xdev/sd0x-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add sd0xdev/sd0x-harness/architecture@git:20260905.3d84d94Pins git:20260905.3d84d94 in mdr.lock. Pin the fingerprint instead.

Architecture design and documentation. Produces 3-architecture.md with component diagrams, data flow, integration points, and architecture decisions. Reads existing tech-spec as input. Use when: designing system architecture, documenting component interactions, creating architecture docs, producing 3-architecture.md. Not for: tech spec writing (use tech-spec), code implementation (use feature-dev), architecture consulting only (use codex-architect).
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.

How to install
mdr add sd0xdev/sd0x-harness/architecture@sha256:034426405cb58a62The line at the top of this page pins the label git:20260905.3d84d94, 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.
