Brainstorm Feature Skill

[!IMPORTANT] SDLC intake that turns a rough idea into an approved BRD-lite brief (Why lane) or delivery contract (Direction lane) at docs/brd/brd-[slug].md, sized by SNC tier.

Optional args: slug=, ticket=<id/url>, mode=interactive|autonomous|channel, channel=, auto_continue=true|false, profile=business|hybrid|technical.

Instructions

When the user asks to perform this workflow, execute the following steps:

Brainstorm Feature Workflow (BRD-lite Why / Direction Contract)

Goal: Turn rough intent into an approved, evidence-backed brief sized to the task, then hand off to planning without reopening settled decisions.

Steps

  1. Frame:
    • Load common-decision-discipline, common-operator-profile, common-task-complexity-routing; load common-business-requirements for the Why lane.
    • Infer operator_profile (never ask). Score SNC: tier=low -> Quick (contract in chat, no file), tier=medium -> Standard, tier=high -> Deep. The tier only rises.
    • Lane: business -> Why (solution-free BRD-lite); technical or unclear technical direction -> Direction (delivery contract); hybrid -> both, compact.
    • Bug symptom without a root cause -> stop and route to dev-fix. Multi-subsystem idea -> list slices, brainstorm the first only.
  2. Ground:
    • Read the smallest useful set of code, tests, docs, and existing docs/brd|prd|srs for the slug before any feasibility or AS-IS claim.
    • Tag each claim in the Evidence ledger: confirmed(<path>), assumed, or unknown.
    • Draft a provisional brief, then write back "You said / I assumed" unless outcome, constraints, non-goals, and acceptance criteria are already stated.
  3. Decide:
    • Ask only decisions that change the result, safety boundary, or public contract: max 3 per round, each with a recommended default and 2-3 options; never re-ask settled facts.
    • Why lane options: build, buy, defer, do nothing. Direction lane: 0-3 technical option cards, only when a real choice exists.
    • Recommend the smallest option that meets the contract; if a critical assumption is unresolved, the one cheapest to abandon.
    • For operator_profile=business, draft owner, SMART metric, and scope fence as one confirm-with-default round.
  4. Approve and hand off:
    • Self-review: placeholders, contradictions, scope, ambiguity.
    • Interactive: end with "Reply ok or corrections"; ok sets approval: approved(<operator>, <YYYY-MM-DD>) for this brief only.
    • Autonomous or channel mode with no confirmation channel: approval: assumed-autonomous; continue.
    • Standard/Deep: save to docs/brd/brd-[slug].md when writes are allowed; mint the slug once. Quick: carry the contract and approval in the Handoff Payload.
    • Route to plan-feature.

Runtime Contract

  • Use for rough feature, ops, process, or technical-direction ideas before a PRD exists for the slug.
  • Required inputs: rough intent; missing owner, metric, or scope fence get drafted defaults, not a block.
  • Return BLOCKED only when the operator rejects drafted defaults for owner, value, or scope.

Handoff Payload

  • slug, operator_profile, lane, snc_tier, approval, contract (outcome, constraints, non-goals, acceptance criteria), SMART metric (Why lane), recommended and rejected options, evidence ledger, assumptions (flagged assumed), open questions, PM handoff checklist.
  • Outcome report with feature_status=requirements_ready | blocked, requirement trace seed, completed/missing evidence, decision needed, and recommended next workflow.

Blocking Questions

  • Ask max 3 at a time with a recommended default and 2-3 options.
