Record facts and assumptions separately. Include product user/problem, purpose, outcomes, MVP/non-goals, flows, requirements, measurable success signals, risks, constraints, dependencies and unresolved blockers.\n\nEvery substantive requirement should be testable or explicitly a hypothesis. Avoid endless tables and feature inflation. Use `../../templates/product-brief.md` or `../../templates/prd.md` and `../../references/spec-writing.md`.\n\n## Deliverable and truthfulness\nLead with the decision or result, then show supporting evidence, explicit assumptions, risks, and a concrete next step. Adapt depth to the user's ask. If required tools or source material are missing, disclose the limit; do not simulate inspection, implementation or research. Never write/modify/deploy without relevant authorization.\n\nRelevant reference: `../../references/spec-writing.md`.\n"
