Design technical architecture, select technology stack, and define implementation strategy from specifications and constitution constraints.
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
- When evaluating technology stack options for a feature - When designing system architecture for new components - When assessing implementation risks and defining mitigations ## Key Principle Architecture decisions must be traceable to specification requirements. Technology choices must comply with constitution constraints. Trade-offs must be documented for every significant decision. ## Process 1. **Assess technology stack** - Evaluate options against constitution requirements 2. **Design architecture** - Components, interfaces, data model, integration points 3. **Define strategy** - Phases, milestones, testing strategy, deployment approach 4. **Assess risks** - Identify risks and define mitigations 5. **Human review** - Approve architecture and strategy before task breakdown ## Tool Use Invoke via babysitter process: `methodologies/spec-kit/spec-kit-planning` Full pipeline: `methodologies/spec-kit/spec-kit-orchestrator`

How to install
mdr add a5c-ai/babysitter/planning-design@sha256:e11afd510027661aThe line at the top of this page pins the label git:20260601.da7723a, 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.
