Spec Forge Architecture

Use this stage to convert the approved framing contract into a top-level solution shape and decomposition plan.

This stage answers: what is the overall approach, what journeys matter, what components exist, and which roles must challenge the design before detail work starts.

Shared Operating Rules

• This skill runs only in Plan mode. If the runtime is not Plan mode, stop and tell the user to switch before continuing.
• Confirm both chat language and file language before architecture questions.
• Keep decisions in chat. YAML remains the persisted source of truth, but the user should not need to inspect files directly.
• Approvals happen from chat summaries, then get persisted into YAML.
