RFC Creator

This skill guides the creation of RFC (Request for Comments) documents for technical proposals.

When to Use

• Proposing a new feature or capability
• Planning architectural changes
• Introducing breaking changes
• Major refactoring proposals
• New configuration formats or APIs
• Integration with external systems

CRITICAL: Pre-RFC Research Phase

Before writing ANY RFC, you MUST complete the following research steps:

Step 0: Get Current Date

Use MCP time tool to get the current date for accurate research:

mcp_call_tool("time", "get_current_time", {"timezone": "Asia/Shanghai"})

This ensures your research queries include the correct year (e.g., 2025) for finding the latest information.

Step 0.1: Online Research (MANDATORY)

For any RFC topic, you MUST conduct comprehensive online research:

1. Search for Mainstream Implementations

Use web_search to find how major projects solve similar problems:

web_search({
  "searchTerm": "[topic] implementation rust [current year] best practices",
  "explanation": "Researching mainstream implementations for RFC topic"
})

Example searches for different RFC topics:

2. Fetch Source Code from Major Projects

Use web_fetch to examine actual implementations:

web_fetch({
  "url": "https://github.com/[project]/[path]/[file]",
  "fetchInfo": "Examining [project]'s implementation of [feature]"
})

Key projects to reference by domain:

3. Document Research Findings

Create a "主流方案调研" (Mainstream Solution Survey) section in the RFC:

## 主流方案调研

在设计本方案之前，我们调研了以下主流实现：

### 1. [Project A] (org/project)

**架构**: [Brief architecture description]

**核心设计**:
```rust
// Key code snippet

关键特性:

• Feature 1
• Feature 2

依赖库:

• lib1 - Description
• lib2 - Description

2. [Project B] (org/project)

[Similar structure...]

方案对比

设计启示

基于以上调研，本 RFC 应采用：

1. [Design decision 1 with rationale]
2. [Design decision 2 with rationale]
3. [Design decision 3 with rationale]

### Step 0.2: Research Checklist

Before proceeding to write the RFC, verify:

- [ ] **Current date obtained** - Used MCP time tool to get accurate date
- [ ] **Web searches completed** - At least 3 relevant searches performed
- [ ] **Source code examined** - Reviewed at least 2-3 major project implementations
- [ ] **Comparison table created** - Documented feature comparison across projects
- [ ] **Design decisions documented** - Listed what to adopt from each project

## RFC Document Structure

### Standard Sections

1. **Header** - Metadata (status, author, date, target version)
2. **摘要/Summary** - Brief overview of the proposal
3. **主流方案调研/Industry Survey** - Research on mainstream implementations (NEW - REQUIRED)

## Step 1: Create RFC Directory

docs/rfcs/ ├── NNNN-short-title.md # Main RFC document └── NNNN-implementation-tracker.md # Implementation progress tracker (optional)

RFC numbers are assigned sequentially: `0001`, `0002`, etc.

## Step 2: RFC Header Template

```markdown
# RFC NNNN: Title

> **作者**: author name/team
> **创建日期**: YYYY-MM-DD
> **目标版本**: vX.Y.Z

Status Definitions

Best Practices

Writing Effective RFCs

1. Be Specific - Include concrete examples and code snippets
2. Consider Edge Cases - Address error handling and unusual scenarios
3. Think About Migration - Always plan for existing users
4. Keep It Focused - One RFC per major feature/change
5. Iterate - RFCs can be updated based on feedback

Code Examples

• Use realistic, working examples
• Show both simple and advanced usage
• Include error cases where relevant

Tables and Diagrams

• Use tables for comparisons and status tracking
• Include ASCII diagrams for architecture when helpful
• Keep formatting consistent

Review Process

1. Share RFC with team for initial feedback
2. Address comments and update document
3. Move to "Review" status when ready
4. Get formal approval before implementation
5. Update status as implementation progresses

RFC Naming Convention

NNNN-short-descriptive-title.md

Examples:

• 0001-config-v2-enhancement.md
• 0002-plugin-architecture.md
• 0003-remote-development-support.md
