description

Analyzes bootstrap artifacts (PRD, SAD, optionally DOD) and decomposes the product into a prioritized, dependency-ordered sequence of epics — coarse-grained deliverable increments, each intended to be implemented as a standalone pipeline run starting at `/sddp-specify`. Use when running /sddp-projectplan or when project-level epic planning is needed after `/sddp-systemdesign`, optionally after `/sddp-devops`, and before `/sddp-init`.

Project Planner — Project Planning Workflow

- This is an optional **project bootstrap** phase. It typically runs after `/sddp-systemdesign`, optionally after `/sddp-devops`, and before `/sddp-init`. - Work at project level, not feature level. - Primary output is `specs/project-plan.md`. - The Product Document (PRD) and Technical Context Document (SAD) are **mandatory** inputs. Halt if either is unresolvable. - The Deployment & Operations Document (DOD) is optional. When absent, skip operational epic extraction but continue. - This is a **self-contained analysis workflow** — no external research delegation. All information comes from the bootstrap artifacts. - Read all available inputs before performing any analysis. - Each epic must be independently deliverable — completing it produces a working increment. - P1 epics alone (across all waves) must yield a working, demonstrable MVP. - Every epic must have at least one traceability tag linking back to a PRD capability, SAD ADR, or DOD DDR. - Epic titles must be suitable as `$ARGUMENTS` to `/sddp-specify` — human-readable, descriptive, self-contained, and capped at 5 words. - The epic checklist format must remain machine-parseable. - Use standard Mermaid `graph LR` syntax for dependency diagrams. Use `
` for line breaks in labels — never `\n`. - Keep dependency diagrams to ≤30 nodes for readability. For large projects, use a summary diagram plus per-wave detail diagrams. - Reuse the existing registration flow in `.github/sddp-config.md`. Do not create a parallel registry. - When refining an existing `specs/project-plan.md`, preserve manually checked `[X]` epics and their completion state. - Do not mention SDD command names, phase names, or workflow references in the generated `specs/project-plan.md`. Use generic terms like "implementation pipeline" or "feature delivery" instead. - Avoid filler or obvious meta statements. Prefer concrete project-specific content.

0. Acquire Baselines

Read before proceeding:

• .github/skills/spec-authoring/SKILL.md — spec types and epic-to-spec mapping
• .github/skills/init-project/SKILL.md — config creation/preservation patterns

1. Gate Check — Resolve Input Documents

Read .github/sddp-config.md if it exists.

For each document: (1) parse **Path**: from config, (2) fall back to default path, (3) halt or skip.

1.1 Resolve Product Document

• Config: ## Product Document → **Path**: → set PRODUCT_DOC
• Fallback: specs/prd.md
• Unresolved → HALT: "Run /sddp-prd first or register in .github/sddp-config.md."

1.2 Resolve Technical Context Document

• Config: ## Technical Context Document → **Path**: → set TECH_CONTEXT_DOC
• Fallback: specs/sad.md
• Unresolved → HALT: "Run /sddp-systemdesign first or register in .github/sddp-config.md."

1.3 Resolve Deployment & Operations Document

• Config: ## Deployment & Operations Document → **Path**: → set DEPLOY_OPS_DOC, HAS_DOD = true
• Fallback: specs/dod.md
• Unresolved → HAS_DOD = false, continue.

2. Read and Parse All Inputs

2.1 Product Document (PRODUCT_DOC)

Extract: product name/vision, capability map (CAP-###, priorities), scope boundaries, user needs, success criteria.

• No explicit capability map → derive from In-Scope Capabilities + User Needs; note IDs should be promoted into PRD.

2.2 Technical Context Document (TECH_CONTEXT_DOC)

Extract: ADRs (ADR-###) with status/context/rationale, tech stack, quality attributes/constraints, integration architecture, cross-cutting concerns.

2.3 Deployment & Operations Document (if HAS_DOD = true)

Extract: DDRs (DDR-###) with status/context/rationale, environment strategy, CI/CD design, infrastructure, observability, reliability targets.

2.4 Additional Context

Read if present: project-instructions.md, README.md. Summarize all into PROJECT_CONTEXT.

3. Determine Mode

• specs/project-plan.md exists with ≥1 E### entry → MODE = REFINE
• Otherwise → MODE = CREATE

REFINE: preserve [X]-marked epics, maintain existing IDs for unchanged epics, append new IDs for additions.

4. Decompose into Epics

4.1 Product Epics ([PRODUCT])

Decompose PRD capabilities into demo-scoped epics — one demo-able deliverable per epic.

• Apply "one demo" test: if demo covers two independent things → split.
• Single capability often yields 1–3 epics; tightly focused capabilities may stay as one.
• Title names the specific capability, ≤5 words. Extra nuance goes after —.
• Tag: {PRD:CAP-###} (or {PRD:CAP-###,CAP-###} for multi-capability). Do not group unrelated capabilities.

4.2 Technical Epics ([TECHNICAL])

• Only ADRs requiring dedicated implementation (framework setup, data layer, shared libraries, integration infra) become epics.
• ADRs absorbed by product epics → no separate epic.
• Tag: {SAD:ADR-N}.

4.3 Operational Epics ([OPERATIONAL])

Only when HAS_DOD = true:

• Identify DDRs requiring setup work (CI/CD, environment provisioning, monitoring, IaC).
• Group related DDRs delivered together. Tag: {DOD:DDR-N} or {DOD:DDR-N,DDR-M}.

4.4 Epic Sizing Guidance

• Product: 2–5 acceptance criteria. >5 → split; 1 trivial → merge.
• Technical: 2–4 deliverables. Single substantial OK; single trivial → merge.
• Operational: 2–4 deliverables. Same heuristics.
• Recommendations for Step 8 review — do not block creation.

4.5 Cross-Cutting Epics

• Multi-document epic → primary category from dominant scope; include all source tags (e.g., {PRD:CAP-005}{SAD:ADR-003}); note cross-cutting nature in details.
• No direct PRD/SAD/DOD reference → tag closest related item; note derivation in details.

5. Build Dependency Graph

1. Identify dependencies: data model, API contract, shared infrastructure, framework.
2. Assign waves:
   • Wave 1 = no dependencies (foundation)
   • Wave N+1 = all dependencies in Wave N or earlier
   • Minimize total waves.
3. Mark [P] within waves: no same-wave dependencies; shared mutable resources → NOT [P].
4. Integration risks: parallel epics touching same data models/APIs, schema migration conflicts, shared config race conditions.
5. Dependency contracts — specify what is needed per dependency:
   • Data: entity + source epic (e.g., "E003 needs User from E001")
   • API: endpoint + source epic (e.g., "E004 calls /api/v1/auth from E002")
   • Library: export + source epic (e.g., "E005 imports auth middleware from E002")
   • Record in Dependency Diagram annotations and Epic Details.

6. Assign Priorities

• P1 product epics ← P1 PRD capabilities. Split capabilities → all epics inherit P1 unless PRD explicitly assigns lower.
• Prerequisites of P1 epics inherit P1.
• Transitive: P2 epic depends on tech epic → tech epic gets ≥P2.
• Validate MVP: P1 epics alone must yield a working product. Fails → promote prerequisites to P1, flag in Step 8.

7. Validate Coverage

• PRD: every CAP-### → ≥1 epic. Missing → create or justify exclusion.
• SAD: every implementation-requiring ADR-### → ≥1 epic. Absorbed ADRs count as covered.
• DOD (if HAS_DOD): every setup-requiring DDR-### → ≥1 epic.
• Document exclusions with rationale in Uncovered items section.

8. Present for Review

Display: epic checklist (by wave), Mermaid dependency diagram, execution wave summary, coverage results.

Confirm with user:

• Epic granularity (too coarse/fine?)
• Priority distribution (P1/P2/P3)
• Wave groupings and parallel safety
• Pipeline hints for TECHNICAL/OPERATIONAL epics (≤3 deliverables → skip_clarify, skip_checklist, lightweight?)
• Missing epics or scope items?

Iterate until confirmed.

9. Write specs/project-plan.md

Ensure the specs/ directory exists before writing.

Mermaid Rules

AoA style, graph LR, <br> for breaks (never \n), parallel epics from same source node, ≤30 nodes, per-wave details if >15 epics.

Pipeline Hints

skip_clarify (epic fully specified) | skip_checklist (low-risk infra) | lightweight (reuse existing research). Opt-in, combinable, absence=no change.

10. Register in Config

Ensure .github/sddp-config.md exists.

New config — create with:

• Document paths: preserved if known, else defaults (specs/prd.md, specs/sad.md, specs/dod.md) if they exist, else blank
• Project Plan: specs/project-plan.md
• MaxChecklistCount: 1, Autopilot: false

Existing config — preserve all unrelated sections and existing document paths. Add/update:

## Project Plan

<!-- A high-level decomposition of the project into epics with dependency ordering and execution waves. -->
<!-- Registered by /sddp-projectplan when specs/project-plan.md is created. -->

**Path**: specs/project-plan.md

Place after ## Deployment & Operations Document, before ## Checklist Settings.

11. Report

Output: Mode (CREATE/REFINE), inputs read (paths + extractions), total epics (by category and priority), wave count + parallel opportunities, coverage gaps, registration confirmation, suggested next step (/sddp-init with prompt).
