plan

What problem does it solve? Turning acceptance criteria and specs into a sound architecture is where AI-assisted development most often goes wrong — plans rest on false premises, cross-track interfaces are left ambiguous, and infrastructure steps get lost. This Skill produces a validated architecture plan (Checkpoint 4 of the DAE pipeline) with human approval gates, charter compliance checks, and a review panel before any code is written. ## Core Features & Use Cases - Architecture proposal with human gate: Drafts components, data flow, coupling, and pinned cross-track interface contracts, grounded in the actual codebase via LSP lookups, then iterates with the human until confirmed. - Charter Check and review panel: Validates the plan against the project CHARTER.md with a compliance table and amendment ADRs, then dispatches an adviser + advocate review panel whose findings are recorded in the handoff. - Runbook generation: When the plan touches provisioning, secrets, DNS, or console-only steps, it writes a runbook.md with per-step human/agent ownership and AC-blocking gate enforcement. - Use Case: After defining ACs and Given/When/Then specs for a new staging-environment feature, invoke the planner to produce plan.md with architecture, phasing, test strategy, and a runbook for the GCP provisioning steps — all approved before implementation begins. ## Quick Start Ask the agent to plan the implementation for the current feature so it produces plan.md with the architecture, charter check, and test strategy.
