Readme Sync

README Sync Skill

Automatically keeps README.md synchronized with actual project components. Scans the .codex directory structure and updates documentation to match reality.

Usage

/readme-sync [--section <name>] [--validate] [--dry-run]

Options

What Gets Synced

1. Agents Section

Scans .codex/agents/*.md and updates:

• Agent count
• Agent table with names, purposes, keywords
• Auto-detects from frontmatter: name, description

2. Skills Section

Scans .codex/skills/*/SKILL.md and .codex/skills/*.md:

• Skill count
• Skill table with usage, description
• Auto-detects from frontmatter

3. Hooks Section

Scans .codex/hooks/*.sh and .codex/hooks/*.md:

• Hook count
• Hook table with events, purposes
• Auto-detects from frontmatter or comments

4. Commands Section

Scans .codex/commands/*.md and .codex/commands/*/:

• Command count
• Command table with descriptions
• Includes subcommand files

5. Stats Section

Updates summary statistics:

| Category | Count |
|----------|-------|
| Agents | 16 |
| Skills | 14 |
| Hooks | 4 |
| Commands | 2 |
| Templates | 5 |
| **Total** | **41** |

Workflow

Step 1: Scan Components

# Scan all .codex directories
find .codex/agents -name "*.md" -type f
find .codex/skills -name "SKILL.md" -o -name "*.md" -type f
find .codex/hooks -name "*.sh" -o -name "*.md" -type f
find .codex/commands -name "*.md" -type f

Step 2: Extract Metadata

For each file, extract:

# From frontmatter
name: component-name
description: Brief description
tools: [Tool1, Tool2]  # for agents
keywords: [key1, key2]

Step 3: Generate Section Content

## Sub-Agents (16)

### Development & Analysis

| Agent | Purpose | Keywords |
|-------|---------|----------|
| `project-analyzer` | Analyze project structure | "analyze", "structure" |
| `code-reviewer` | Review code quality | "review", "PR" |
...

Step 4: Update README

• Find existing section by header
• Replace content between headers
• Preserve custom content outside synced sections

Section Markers

Use these markers to define sync boundaries:

<!-- README-SYNC:agents:start -->
## Sub-Agents (16)
...content auto-generated...
<!-- README-SYNC:agents:end -->

<!-- README-SYNC:skills:start -->
## Skills (14)
...content auto-generated...
<!-- README-SYNC:skills:end -->

Without markers, the skill will find sections by ## Sub-Agents or ## Agents headers.

Configuration

Auto-Sync Settings

{
  "readme-sync": {
    "auto_on_change": true,
    "sections": ["agents", "skills", "hooks", "commands", "stats"],
    "preserve_custom": true,
    "use_markers": true,
    "table_format": "markdown"
  }
}

Section Templates

# .codex/readme-sync-config.yml
sections:
  agents:
    header: "## Sub-Agents ({count})"
    columns:
      - name: "Agent"
        source: "name"
        format: "`{value}`"
      - name: "Purpose"
        source: "description"
        truncate: 50
      - name: "Keywords"
        source: "keywords"
        format: "\"{value}\""

  skills:
    header: "## Skills ({count})"
    group_by: "category"
    columns:
      - name: "Skill"
        source: "name"
      - name: "Usage"
        source: "usage"
      - name: "Description"
        source: "description"

Integration

With auto-doc-sync Hook

# Hook triggers readme-sync when .codex files change
# In hooks/auto-doc-sync.sh:
if [[ "$TOOL_INPUT" == *".codex/"* ]]; then
    # Trigger README sync suggestion
fi

With /agile-sync

# agile-sync includes readme-sync as step 3
/agile-sync  # Includes README stats update

Manual Trigger

# Full sync
/readme-sync

# Specific section
/readme-sync --section skills

# Validate only
/readme-sync --validate

Best Practices

DO

• ✅ Use section markers for precise updates
• ✅ Run after adding new agents/skills
• ✅ Include in PR checklist
• ✅ Keep frontmatter accurate in source files

DON'T

• ❌ Manually edit synced sections (will be overwritten)
• ❌ Remove section markers
• ❌ Skip validation before releases

Troubleshooting

"Section not found in README"

# Add section markers or headers:
## Sub-Agents
<!-- or -->
<!-- README-SYNC:agents:start -->
<!-- README-SYNC:agents:end -->

"Component not detected"

# Ensure frontmatter is valid:
---
name: my-component
description: Brief description
---

"Stats mismatch"

# Force full recalculation:
/readme-sync --section stats
