Plan Feature Skill

> !IMPORTANT] > Plan a feature from BRD-lite brief or clear intent into PRD (What), decisions, implementation plan, and task slices.

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

Instructions

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

Feature Planning Workflow (PRD / What)

Goal: Produce a PM-owned decision-complete PRD, delivery plan, and IT Department handoff before code starts.

Steps

1. Load context:

• Load baseline PRD section and search docs/brd/ for the matching [slug]; if multiple candidates exist and intent is unclear, ask the user to choose/input the target slug.
• Load BRD-lite, ticket text, existing specs, repo patterns, common-product-requirements, common-operator-profile, quality-engineering-business-analysis, and matched framework skills.
• Carry forward operator_profile, BRD objective IDs, SMART metric, scope fence, assumptions, glossary, risks, and delivery context.

1. Interview:

• Draft a provisional PRD direction from current context before asking.
• Ask only for business logic, scope, constraints, and acceptance criteria that cannot be inferred.
• Ask max 3 blocking decisions at a time; include a recommended default and 2-3 options for each.
• Treat non-critical unknowns as explicit assumptions.
• Confirm problem statement, assumptions, target users, JTBD/use cases, platforms, data, analytics, security, performance, rollout, and non-goals.
• Confirm each requirement has owner, priority, and status.
• Confirm success metrics and guardrails that must not regress.
• Stop when requirements are actionable.

1. Draft PRD:

• Save to docs/prd/prd-[slug].md when file writes are allowed.
• Keep "what" separate from "how".
• Add stable requirement IDs and AC IDs.
• Use Given/When/Then AC when behavior can be misread.
• Check user stories for specific persona, business value, INVEST, happy path, edge path, and negative path.
• Link each requirement back to BRD-lite business objective.
• Include risk categories, rollout/ops, decision log, analytics/telemetry, and changelog.
• Mark unresolved blocking product decisions as blockers.
• Include a RACI table for BA, PM, architect, backend, frontend, mobile, QA, release, and business/UAT approver when more than one delivery role is involved.

1. Create implementation plan:

• Define components, contracts, data changes, migrations, risks, and verification.
• Slice work into fresh-context tasks.
• Map each task slice to requirement IDs, AC IDs, likely owner role, repo/module, expected artifact, and verification lane.
• Estimate each slice (t-shirt size + confidence); roll up a delivery-window range in time/cost terms for operator_profile=business, points otherwise.
• Identify whether design-solution is required before coding.

1. Route:

• Continue when assumptions are non-critical; return BLOCKED for missing owner, untestable AC, approval, or release constraint.
• Architecture unclear -> design-solution; approved build-ready plan with AC IDs and trace -> implementation-readiness.

Runtime Contract

• Use after BRD-lite or when clear feature intent exists but PRD does not.
• Required inputs: BRD-lite or equivalent intent, plus enough context to name users, goals, and constraints.
• Return BLOCKED only for missing owner, untestable AC, approval, or release constraint.

Handoff Payload

• slug, operator_profile, PRD path, REQ-*, AC-*, decisions, RACI, rollout notes, task slices, delivery-window estimate, verification plan, outcome report, next workflow.

Blocking Questions

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