# SOP: Shared Resources Registry

Keep prompts, skills, and guidelines in sync across repos and agents.

## Why Shared Resources?

> "Update once, propagate everywhere." — BoardKit Orchestrator

Without a shared registry:

- Prompts drift between repos
- Agents in different projects behave inconsistently
- SOPs get outdated and forgotten
- New team members copy/paste stale templates

With a shared registry:

- Single source of truth for agent behavior
- Consistent task workflows across all projects
- Easy onboarding (point to the registry)
- Version-controlled evolution

## Directory Structure

### Single Repo (Simple)

```
my-project/
├── prompt-registry/           # Workflow prompts
│   ├── sprint-planning.md
│   ├── code-review.md
│   └── ...
├── AGENTS.md                  # Agent personality/rules
├── CLAUDE.md                  # Model-specific notes
└── docs/
    └── BEST-PRACTICES.md      # Team patterns
```

### Multi-Repo (Shared Assets)

```
workspace/
├── shared/                    # Shared across all repos
│   ├── prompt-registry/       # Universal prompts
│   │   ├── sprint-planning.md
│   │   └── cross-model-review.md
│   ├── skills/                # Agent skills/capabilities
│   │   ├── github.md
│   │   └── research.md
│   └── guidelines/            # Universal rules
│       ├── AGENTS-BASE.md
│       └── SECURITY-RULES.md
│
├── project-a/                 # Project-specific
│   ├── AGENTS.md              # Extends shared/guidelines/AGENTS-BASE.md
│   ├── prompt-registry/       # Project-specific prompts
│   │   └── deploy-checklist.md
│   └── ...
│
└── project-b/
    ├── AGENTS.md
    └── ...
```

## Mounting Strategies

### Strategy 1: Copy + Customize (Recommended for MVP)

Copy shared resources into each repo, customize as needed:

```bash
# Initial setup
cp -r ../shared/prompt-registry ./prompt-registry
cp ../shared/guidelines/AGENTS-BASE.md ./AGENTS.md

# Periodically sync
diff -u ../shared/prompt-registry ./prompt-registry
# Review changes, merge manually
```

**Pros:** Simple, no tooling required, full control per repo
**Cons:** Manual sync, potential drift

### Strategy 2: Symlinks

Link shared resources into each repo:

```bash
# From project directory
ln -s ../shared/prompt-registry ./prompt-registry-shared
ln -s ../shared/guidelines/AGENTS-BASE.md ./AGENTS-SHARED.md
```

**Pros:** Always in sync, no manual updates
**Cons:** Doesn't work on Windows, requires absolute paths for some tools

### Strategy 3: Git Submodules

Maintain shared resources in a separate repo:

```bash
# Add submodule
git submodule add https://github.com/org/shared-resources.git shared

# Update
git submodule update --remote
```

**Pros:** Versioned, works across orgs
**Cons:** Git submodule complexity

### Strategy 4: NPM/pnpm Package (Future)

Publish shared resources as a package:

```json
{
  "dependencies": {
    "@org/agent-resources": "^1.0.0"
  }
}
```

**Pros:** Semantic versioning, automatic updates
**Cons:** Requires package infrastructure

## What to Share

### Always Share

- Cross-model review prompt (consistency is critical)
- Security review checklist
- Definition of Done template
- Sprint planning prompt

### Share Carefully

- Agent personality (AGENTS.md) — may need project-specific tweaks
- API endpoint references — URLs differ per environment
- Notification channels — project-specific

### Don't Share

- Secrets or API keys (use env vars)
- Project-specific business logic
- Team member names/contacts

---

## Referencing Shared Resources

### In Task Descriptions

```markdown
## Instructions

Follow the standard code review process.
See prompt: `prompt-registry/cross-model-review.md`
```

### In Agent Prompts

```
You are working on project-a. Use the shared guidelines at `shared/guidelines/AGENTS-BASE.md`
combined with project-specific rules at `AGENTS.md`.
```

### In AGENTS.md

```markdown
# AGENTS.md

This project extends the base guidelines at `../shared/guidelines/AGENTS-BASE.md`.

## Project-Specific Rules

- Use project-a-specific API at http://localhost:4000
- Deploy requires approval from @project-lead
```

---

## Versioning & Updates

### Semantic Versioning for Shared Resources

```
shared/
├── VERSION                    # 1.2.0
├── CHANGELOG.md               # What changed
└── prompt-registry/
    └── ...
```

### Update Protocol

1. **Propose** — Create PR/issue in shared resources repo
2. **Review** — Team reviews impact across all projects
3. **Test** — Verify in one project first
4. **Propagate** — Update all repos (manual or via sync script)
5. **Announce** — Notify team of changes

## Migration Checklist

Moving from ad-hoc prompts to shared registry:

- [ ] Audit existing prompts across all repos
- [ ] Identify duplicates and conflicts
- [ ] Create canonical versions in shared location
- [ ] Update all repos to reference shared versions
- [ ] Remove duplicate copies
- [ ] Document the new structure in each repo's README
- [ ] Train team on update protocol
