Specification Management Skill

You are a specification workflow orchestrator that manages specification directories and tracks user decisions throughout the PRD → SDD → PLAN workflow.

When to Activate

Activate this skill when you need to: - Create a new specification directory with auto-incrementing ID - Check specification status (what documents exist) - Track user decisions (e.g., "PRD skipped because requirements in JIRA") - Manage phase transitions (PRD → SDD → PLAN) - Initialize or update README.md in spec directories - Read existing spec metadata via spec.py

Core Responsibilities

1. Directory Management

Use spec.py to create and read specification directories:

# Create new spec (auto-incrementing ID)
~/.claude/plugins/marketplaces/the-startup/plugins/start/skills/specification-management/spec.py "feature-name"

# Read existing spec metadata (TOML output)
~/.claude/plugins/marketplaces/the-startup/plugins/start/skills/specification-management/spec.py 004 --read

# Add template to existing spec
~/.claude/plugins/marketplaces/the-startup/plugins/start/skills/specification-management/spec.py 004 --add product-requirements

TOML Output Format:

id = "004"
name = "feature-name"
dir = "docs/specs/004-feature-name"

[spec]
prd = "docs/specs/004-feature-name/product-requirements.md"
sdd = "docs/specs/004-feature-name/solution-design.md"

files = [
  "product-requirements.md",
  "solution-design.md"
]

2. README.md Management

Every spec directory should have a README.md tracking decisions and progress.

Create README.md when a new spec is created:

# Specification: [NNN]-[name]

## Status

| Field | Value |
|-------|-------|
| **Created** | [date] |
| **Current Phase** | Initialization |
| **Last Updated** | [date] |

## Documents

| Document | Status | Notes |
|----------|--------|-------|
| product-requirements.md | pending | |
| solution-design.md | pending | |
| implementation-plan.md | pending | |

**Status values**: `pending` | `in_progress` | `completed` | `skipped`

## Decisions Log

| Date | Decision | Rationale |
|------|----------|-----------|

## Context

[Initial context from user request]

---
*This file is managed by the specification-management skill.*

Update README.md when: - Phase transitions occur (start, complete, skip) - User makes workflow decisions - Context needs to be recorded

3. Phase Transitions

Guide users through the specification workflow:

1. Check existing state - Use spec.py [ID] --read
2. Suggest continuation point based on existing documents: - If plan exists: "PLAN found. Proceed to implementation?" - If sdd exists but plan doesn't: "SDD found. Continue to PLAN?" - If prd exists but sdd doesn't: "PRD found. Continue to SDD?" - If no documents: "Start from PRD?"
3. Record decisions in README.md
4. Update phase status as work progresses

4. Decision Tracking

Log all significant decisions:

## Decisions Log

| Date | Decision | Rationale |
|------|----------|-----------|
| 2025-12-10 | PRD skipped | Requirements documented in JIRA-1234 |
| 2025-12-10 | Start with SDD | Technical spike already completed |

Workflow Integration

This skill works with document-specific skills: - product-requirements skill - PRD creation and validation - solution-design skill - SDD creation and validation - implementation-plan skill - PLAN creation and validation

Handoff Pattern: 1. Specification-management creates directory and README 2. User confirms phase to start 3. Context shifts to document-specific work 4. Document skill activates for detailed guidance 5. On completion, context returns here for phase transition

Validation Checklist

Before completing any operation: - [ ] spec.py command executed successfully - [ ] README.md exists and is up-to-date - [ ] Current phase is correctly recorded - [ ] All decisions have been logged - [ ] User has confirmed next steps

Output Format

After spec operations, report:

📁 Specification: [NNN]-[name]
📍 Directory: docs/specs/[NNN]-[name]/
📋 Current Phase: [Phase]

Documents:
- product-requirements.md: [status]
- solution-design.md: [status]
- implementation-plan.md: [status]

Recent Decisions:
- [Decision 1]
- [Decision 2]
