Create Request For Comments
Create a new RFC document proposing and discussing a change.
Anti-Hallucination Guidelines
RFCs propose changes to real systems, so ground every claim before writing:
- Verify current state: explore the codebase to understand what exists today
- Reference actual code: don't invent APIs or patterns; find real examples
- Check dependencies: confirm libraries/tools mentioned actually exist in the project
- Validate assumptions: each claim about current state must be verified
Workflow
Phase 1: Explore and Gather Context
Understand the codebase before writing anything. If the Task tool is available, use the Explore agent:
Use Task tool with Explore agent:
- prompt: "Analyze the codebase to understand [RFC_TOPIC]. Find: 1) Current implementation patterns, 2) Related components and their interactions, 3) Existing similar features, 4) Technical constraints. Return verified findings with file paths."
- subagent_type: "Explore"
No Task tool available: explore directly with grep/glob/read before writing,
covering the same four questions (current patterns, related components, existing
similar features, technical constraints). Either way, keep what you find: it feeds
the Background and Detailed Design sections in Phase 6.
Phase 2: Parse Arguments
- Extract proposal title from
$ARGUMENTS - Check for a variant keyword:
minimal,standard, ordetailed - If a variant is found, remove it from the title
- Default variant:
standard
Phase 3: Determine RFC Number
- Scan
docs/rfc/for existing files matchingRFC-XXXX-* - Increment the highest number by 1 (start at
0001if none exist) - Format as a 4-digit padded number (e.g.
0001,0023)
Phase 4: Sanitize Title for Filename
Convert the title to kebab-case, lowercase, special characters stripped.
Example: "Add GraphQL API Support" -> add-graphql-api-support
Phase 5: Get Author Information
Run git config user.name, falling back to "Development Team" if empty.
Phase 6: Load and Populate Template
Template location: assets/templates/, select based on variant:
minimal->minimal.md: Summary, Motivation, Proposal, Open Questions. Use for small changes.standard->standard.md(default): adds Rationale and Alternatives, Implementation Plan, Testing Plan, Migration Strategy, Timeline. Use for most feature proposals.detailed->detailed.md: full set including Goals/Non-Goals, Security Considerations, Performance Implications, Monitoring and Metrics. Use for major/architectural changes.
Draft real content for every {{PLACEHOLDER}} present in the selected template:
each variant has its own set (metadata fields, body sections, risk tables,
alternatives, review history, and so on). Base each one on the Phase 1 findings
or on explicit reasoning about the proposal; never leave a placeholder token
literally in the output. The written RFC must contain zero unresolved
{{...}} tokens.
Phase 7: Create RFC File
- Filename:
docs/rfc/RFC-XXXX-kebab-case-title.md - Ensure
docs/rfc/exists, write populated content, set status to "Draft"
Phase 8: Report Creation
Show the RFC number, title, file path, and next-step guidance (share for feedback, update status as it progresses).
Usage Examples
docs-rfc "Add GraphQL API Support"
docs-rfc minimal "Update Logging Format"
docs-rfc detailed "Migration to Microservices Architecture"
RFC Status Lifecycle
Draft -> In Review -> Accepted / Rejected (or Withdrawn at any point,
Implemented after accepted work ships). Update the status field as the RFC moves
through review.
Good Practices
- Write the RFC before starting implementation, not after
- Include concrete examples and real code references, not hypotheticals
- Document alternatives considered and why they were rejected
- Link related ADRs, issues, or other RFCs
- Keep it updated as a living document during review
