Activation Contract

Use when drafting an OpenSpec design.md after proposal/spec context exists or when technical uncertainty must be resolved for SDD planning.

Hard Rules

MUST explore the real codebase read-only before technical questions or drafting; never guess architecture.
Follow the grilling skill: one question at a time, recommendation attached, stop and wait; read code for technical answers when possible.
Follow the native-question-ux skill for question presentation; ask one question at a time and stop after each answer.
Artifacts default to English; interview/summaries/gates use the user's language.
Plan-only: no code edits, builds, installs, tests, or state changes. Only write planning .md files after explicit approval.
File Changes entries must name a real file path or Create. No code bodies. Enough precision for the implementer to execute without re-deciding. Keep under 800 words.
When delegated by grill, return the approved draft and do not write files; the orchestrator owns the single write step.
