description	Write OpenSpec proposal.md artifacts (why + what). TRIGGER when: capturing requirements, scope, and impact for a spec-driven feature. SKIP: technical design (use spec-design); external documentation research (use research-methodology).

OpenSpec Proposal Writing

Guide for creating proposal.md -- the WHY document that anchors the entire workflow.

Output Path

Write to: {specs_path}/proposal.md

Path Enforcement: The specs_path MUST be .scaffolding/conversations/{UUID}/specs/ where {UUID} is a valid UUID (format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx). NEVER use descriptive folder names.

Required Sections

Section	Purpose	Content
Why	Motivation	1-2 sentences. What problem? Why now?
What Changes	Scope	Bullet list. New capabilities, modifications, removals. Mark BREAKING
Capabilities	Contract	New + modified capabilities (kebab-case names)
Impact	Blast radius	Affected code, APIs, dependencies, systems
Agent Assignment	Routing	Table of agents, roles, artifacts
Rollback Plan	Safety	Revert points, manual steps, affected systems

Capabilities Section (Critical)

This section creates the contract between proposal and design phases.

New Capabilities

• Use kebab-case: user-auth, data-export, api-rate-limiting
• Each becomes a requirement group in design.md
• Brief description of what the capability covers

Modified Capabilities

• Only list if spec-level REQUIREMENTS change (not just implementation)
• Check .scaffolding/openspec/specs/ for existing names
• Leave empty if no requirement changes

Quality Checklist

• Goals are concrete and measurable (not vague)
• Edge cases identified in Impact section
• All affected agents listed in Agent Assignment
• Rollback plan has specific revert steps
• Capabilities use kebab-case naming
• No implementation details (those go in design.md)
• Stakeholder impact addressed

Template Structure

## Why

[1-2 sentences: problem + urgency]

## What Changes

- [Specific change 1]
- [Specific change 2]
- **BREAKING**: [Breaking change, if any]

## Capabilities

### New Capabilities
- `capability-name`: Brief description

### Modified Capabilities
- `existing-name`: What requirement is changing

## Impact

[Affected code, APIs, dependencies, systems]

## Agent Assignment

| Agent | Role | Artifacts |
|-------|------|-----------|
| architect | Analyst + Coordinator | proposal.md, design.md, tasks.md |
| researcher | External Research (if needed) | ResearchPack |
| developer | Developer | Source code |
| reviewer | Reviewer | Review report |

## Rollback Plan

- [ ] Identify revert points
- [ ] Document manual rollback steps
- [ ] List affected systems

Anti-Patterns

Avoid	Instead
Vague goals ("improve performance")	Measurable goals ("reduce p95 latency below 200ms")
Implementation details	Save for design.md
Missing rollback plan	Always include revert strategy
Skipping capabilities section	This is the design contract
