Core Concept: Registry System

Purpose: Understanding how component tracking and distribution works
Priority: CRITICAL - Load this before working with registry

---

What Is the Registry?

The registry is a centralized catalog (registry.json) that tracks all components in OpenAgents Control:

• Agents - AI agent prompts
• Subagents - Delegated specialists
• Commands - Slash commands
• Tools - Custom tools
• Contexts - Context files

Location: registry.json (root directory)

Registry Schema

Top-Level Structure

{
  "version": "0.5.0",
  "schema_version": "2.0.0",
  "components": {
    "agents": [...],
    "subagents": [...],
    "commands": [...],
    "tools": [...],
    "contexts": [...]
  },
  "profiles": {
    "essential": {...},
    "developer": {...},
    "business": {...}
  }
}

Component Entry

{
  "id": "frontend-specialist",
  "name": "Frontend Specialist",
  "type": "agent",
  "path": ".opencode/agent/development/frontend-specialist.md",
  "description": "Expert in React, Vue, and modern CSS",
  "category": "development",
  "tags": ["react", "vue", "css", "frontend"],
  "dependencies": ["subagent:tester"],
  "version": "0.5.0"
}

Fields:

• id: Unique identifier (kebab-case)
• name: Display name
• type: Component type (agent, subagent, command, tool, context)
• path: File path relative to repo root
• description: Brief description
• category: Category name (for agents)
• tags: Optional tags for discovery
• dependencies: Optional dependencies
• version: Version when added/updated

---

Auto-Detect System

The auto-detect system scans .opencode/ and automatically updates the registry.

How It Works

1. Scan .opencode/ directory
2. Find all .md files with frontmatter
3. Extract metadata (description, category, type, tags)
4. Validate paths exist
5. Generate component entries
6. Update registry.json

Running Auto-Detect

# Dry run (see what would be added)
./scripts/registry/auto-detect-components.sh --dry-run

# Actually add components
./scripts/registry/auto-detect-components.sh --auto-add

# Force update existing entries
./scripts/registry/auto-detect-components.sh --auto-add --force

What Gets Detected

✅ Agents - .opencode/agent/{category}/*.md
✅ Subagents - .opencode/agent/subagents/**/*.md
✅ Commands - .opencode/command/**/*.md
✅ Tools - .opencode/tool/**/index.ts
✅ Contexts - .opencode/context/**/*.md

Frontmatter Requirements

For auto-detect to work, files must have frontmatter:

---
description: "Brief description"
category: "category-name"  # For agents
type: "agent"              # Or subagent, command, tool, context
tags: ["tag1", "tag2"]     # Optional
---

---

Validation

Registry Validation

# Validate registry
./scripts/registry/validate-registry.sh

# Verbose output
./scripts/registry/validate-registry.sh -v

What Gets Validated

✅ Schema - Correct JSON structure
✅ Paths - All paths exist
✅ IDs - Unique IDs
✅ Categories - Valid categories
✅ Dependencies - Dependencies exist
✅ Versions - Version consistency

Validation Errors

# Example errors
ERROR: Path does not exist: .opencode/agent/core/missing.md
ERROR: Duplicate ID: frontend-specialist
ERROR: Invalid category: invalid-category
ERROR: Missing dependency: subagent:nonexistent

---

Component Profiles

Profiles are pre-configured component bundles for quick installation.

Available Profiles

Essential Profile

Purpose: Minimal setup for basic usage

Includes:

• Core agents (openagent, opencoder)
• Essential commands (commit, test)
• Core context files

"essential": {
  "description": "Minimal setup for basic usage",
  "components": [
    "agent:openagent",
    "agent:opencoder",
    "command:commit",
    "command:test"
  ]
}

---

Developer Profile

Purpose: Full development setup

Includes:

• All core agents
• Development specialists
• All subagents
• Dev commands
• Dev context files

"developer": {
  "description": "Full development setup",
  "components": [
    "agent:*",
    "subagent:*",
    "command:*",
    "context:core/*",
    "context:development/*"
  ]
}

---

Business Profile

Purpose: Content and product focus

Includes:

• Core agents
• Content specialists
• Product specialists
• Content context files

"business": {
  "description": "Content and product focus",
  "components": [
    "agent:openagent",
    "agent:copywriter",
    "agent:technical-writer",
    "context:core/*",
    "context:content/*"
  ]
}

---

Install System

The install system uses the registry to distribute components.

Installation Flow

1. User runs install.sh
2. Check for local registry.json (development mode)
3. If not local, fetch from GitHub (production mode)
4. Parse registry.json
5. Show component selection UI
6. Resolve dependencies
7. Download components from GitHub
8. Install to .opencode/
9. Handle collisions (skip/overwrite/backup)

Local Registry (Development)

# Test with local registry
REGISTRY_URL="file://$(pwd)/registry.json" ./install.sh --list

# Install with local registry
REGISTRY_URL="file://$(pwd)/registry.json" ./install.sh developer

Remote Registry (Production)

# Install from GitHub
./install.sh developer

# List available components
./install.sh --list

---

Dependency Resolution

Dependency Format

"dependencies": [
  "subagent:tester",
  "context:core/standards/code"
]

Resolution Rules

1. Parse dependency string (type:id)
2. Find component in registry
3. Check if already installed
4. Add to install queue
5. Recursively resolve dependencies
6. Install in dependency order

Example

User installs: frontend-specialist
  ↓
Depends on: subagent:tester
  ↓
Depends on: context:core/standards/tests
  ↓
Install order:
  1. context:core/standards/tests
  2. subagent:tester
  3. frontend-specialist

---

Collision Handling

When installing components that already exist:

Collision Strategies

1. Skip - Keep existing file
2. Overwrite - Replace with new file
3. Backup - Backup existing, install new

Interactive Mode

File exists: .opencode/agent/core/openagent.md
[S]kip, [O]verwrite, [B]ackup, [A]ll skip, [F]orce all? 

Non-Interactive Mode

# Skip all collisions
./install.sh developer --skip-existing

# Overwrite all collisions
./install.sh developer --force

# Backup all collisions
./install.sh developer --backup

---

Version Management

Version Fields

• Registry version: Overall registry version (e.g., "0.5.0")
• Schema version: Registry schema version (e.g., "2.0.0")
• Component version: When component was added/updated

Version Consistency

# Check version consistency
cat VERSION
cat package.json | jq '.version'
cat registry.json | jq '.version'

# All should match

Updating Versions

# Bump version
echo "0.X.Y" > VERSION
jq '.version = "0.X.Y"' package.json > tmp && mv tmp package.json
jq '.version = "0.X.Y"' registry.json > tmp && mv tmp registry.json

---

CI/CD Integration

GitHub Workflows

Validate Registry (PR Checks)

# .github/workflows/validate-registry.yml
- name: Validate Registry
  run: ./scripts/registry/validate-registry.sh

Auto-Update Registry (Post-Merge)

# .github/workflows/update-registry.yml
- name: Update Registry
  run: ./scripts/registry/auto-detect-components.sh --auto-add

Version Bump (On Release)

Best Practices

Adding Components

✅ Add frontmatter - Required for auto-detect
✅ Run auto-detect - Don't manually edit registry
✅ Validate - Always validate after changes
✅ Test locally - Use local registry for testing

Maintaining Registry

✅ Auto-detect first - Let scripts handle updates
✅ Validate often - Catch issues early
✅ Version consistency - Keep versions in sync
✅ CI validation - Automate validation in CI

Dependencies

✅ Explicit dependencies - List all dependencies
✅ Test resolution - Verify dependencies resolve
✅ Avoid cycles - No circular dependencies

---

Common Issues

Path Not Found

Problem: Registry references non-existent path
Solution: Run auto-detect or fix path manually

Duplicate ID

Problem: Two components with same ID
Solution: Rename one component

Invalid Category

Problem: Agent has invalid category
Solution: Use valid category (core, development, content, data, product, learning)

Missing Dependency

Problem: Dependency doesn't exist in registry
Solution: Add dependency or remove reference

Version Mismatch

Problem: VERSION, package.json, registry.json don't match
Solution: Update all version files to match
