Prpm Development

PRPM Development Knowledge Base

Complete knowledge base for developing PRPM - the universal package manager for AI prompts, agents, and rules.

Mission

Build the npm/cargo/pip equivalent for AI development artifacts. Enable developers to discover, install, share, and manage prompts across Cursor, Claude Code, Continue, Windsurf, and future AI editors.

Core Architecture

Universal Format Philosophy

1. Canonical Format: All packages stored in normalized JSON structure
2. Smart Conversion: Server-side format conversion with quality scoring
3. Zero Lock-In: Users convert between any format without data loss
4. Format-Specific Optimization: IDE-specific variants (e.g., Claude with MCP)

Package Manager Best Practices

• Semantic Versioning: Strict semver for all packages
• Dependency Resolution: Smart conflict resolution like npm/cargo
• Lock Files: Reproducible installs (prpm-lock.json)
• Registry-First: All operations through central registry API
• Caching: Redis caching for converted packages (1-hour TTL)

Developer Experience

• One Command Install: prpm install @collection/nextjs-pro gets everything
• Auto-Detection: Detect IDE from directory structure (.cursor/, .claude/)
• Format Override: --as claude to force specific format
• Telemetry Opt-Out: Privacy-first with easy opt-out
• Beautiful CLI: Clear progress indicators and colored output

Git Workflow - CRITICAL RULES

⚠️ NEVER PUSH DIRECTLY TO MAIN ⚠️

PRPM uses a branch-based workflow with CI/CD automation. Direct pushes to main bypass all safety checks and can break production.

ALWAYS follow this workflow:

1. Create a branch for your changes:

   git checkout -b feature/your-feature-name
   # or
   git checkout -b fix/bug-description
   

2. Make commits on your branch using conventional commit format:

   git add [files]
   git commit -m "feat: add OpenCode format support"
   

Commit Message Format

Use conventional commit prefixes for all commits:

Why this matters:

• Automated changelog generation
• Clear commit history
• Easier code review
• Semantic versioning automation

Bad commits to avoid:

# ❌ Too vague
git commit -m "fixes"
git commit -m "updates"
git commit -m "changes"

# ✅ Clear and descriptive
git commit -m "fix: resolve schema validation for Claude agents"
git commit -m "feat: add support for Droid format subtypes"

3. Push your branch:

   git push origin feature/your-feature-name
   

4. Create a Pull Request on GitHub:

   • Automated CI tests run
   • Code review happens
   • Deployments are controlled

5. After PR approval, merge through GitHub UI:

   • Triggers automated deployment
   • Ensures CI passes first
   • Maintains deployment history

Why this matters:

• Main branch is protected and deploys to production
• Direct pushes skip CI tests, linting, type checks
• Can deploy broken code to 7500+ package registry
• Breaks audit trail and rollback capability
• GitHub Actions workflows expect PRs, not direct pushes

If you accidentally pushed to main:

1. DO NOT force push to revert - breaks CI/CD
2. Create a revert commit on a branch
3. Open PR to fix the issue properly
4. Let CI/CD handle the corrective deployment

Exception: Only repository admins can push to main for emergency hotfixes (with explicit approval).

Format Conversion System

Supported Formats

Cursor (.mdc)

• MDC frontmatter with ruleType, alwaysApply, description
• Markdown body
• Simple, focused on coding rules
• No structured tools/persona definitions

Claude (agent format)

• YAML frontmatter: name, description
• Optional: tools (comma-separated), model (sonnet/opus/haiku/inherit)
• Markdown body
• Supports persona, examples, instructions

Continue (JSON)

• JSON configuration
• Simple prompts, context rules
• Limited metadata support

Windsurf

• Similar to Cursor
• Markdown-based
• Basic structure

Conversion Quality Scoring (0-100)

Start at 100 points, deduct for lossy conversions:

• Missing tools: -10 points
• Missing persona: -5 points
• Missing examples: -5 points
• Unsupported sections: -10 points each
• Format-specific features lost: -5 points

Lossless vs Lossy Conversions

• Canonical ↔ Claude: Nearly lossless (95-100%)
• Canonical ↔ Cursor: Lossy on tools/persona (70-85%)
• Canonical ↔ Continue: Most lossy (60-75%)

Collections System

Collections are curated bundles of packages that solve specific use cases.

Collection Structure

{
  "id": "@collection/nextjs-pro",
  "name": "Next.js Professional Setup",
  "description": "Complete Next.js development setup",
  "category": "frontend",
  "packages": [
    {
      "packageId": "react-best-practices",
      "required": true,
      "reason": "Core React patterns"
    },
    {
      "packageId": "typescript-strict",
      "required": true,
      "reason": "Type safety"
    },
    {
      "packageId": "tailwind-helper",
      "required": false,
      "reason": "Styling utilities"
    }
  ]
}

Collection Installation Behavior

Collections can be installed using multiple identifier formats. The system intelligently resolves collections based on the format provided.

Installation Formats (Priority Order)

1. Recommended Format: collections/{slug}

prpm install collections/nextjs-pro
prpm install collections/nextjs-pro@2.0.0

• Behavior: Searches across ALL scopes for name_slug = "nextjs-pro"
• Resolution: Prioritizes by official → verified → downloads → created_at
• Use Case: User-friendly format for discovering popular collections
• Example: Finds khaliqgant/nextjs-pro even when searching collections/nextjs-pro

2. Explicit Scope: {scope}/{slug} or @{scope}/{slug}

prpm install khaliqgant/nextjs-pro
prpm install @khaliqgant/nextjs-pro
prpm install khaliqgant/nextjs-pro@2.0.0

• Behavior: Searches for specific scope and name_slug combination
• Resolution: Exact match only within that scope
• Use Case: Installing a specific author's version when multiple exist
• Example: Gets specifically the collection published by khaliqgant

3. Name-Only Format: {slug} (Legacy/Fallback)

prpm install nextjs-pro
prpm install nextjs-pro@1.0.0

• Behavior: Defaults to scope = "collection", then falls back to cross-scope search
• Resolution: First tries scope="collection", then searches all scopes
• Use Case: Quick installs when collection origin doesn't matter
• Recommendation: Prefer collections/{slug} for clarity

Registry Resolution Logic

Implementation Location: app/packages/registry/src/routes/collections.ts:485-519

// When scope is 'collection' (default from CLI for collections/* prefix):
if (scope === 'collection') {
  // Search across ALL scopes, prioritize by:
  // 1. Official collections (official = true)
  // 2. Verified authors (verified = true)
  // 3. Most downloads
  // 4. Most recent
  SELECT * FROM collections
  WHERE name_slug = $1
  ORDER BY official DESC, verified DESC, downloads DESC, created_at DESC
  LIMIT 1
} else {
  // Explicit scope: exact match only
  SELECT * FROM collections
  WHERE scope = $1 AND name_slug = $2
  ORDER BY created_at DESC
  LIMIT 1
}

CLI Resolution Logic

Implementation Location: app/packages/cli/src/commands/collections.ts:487-504

// Parse collection spec:
// - collections/nextjs-pro → scope='collection', name_slug='nextjs-pro'
// - khaliqgant/nextjs-pro → scope='khaliqgant', name_slug='nextjs-pro'
// - @khaliqgant/nextjs-pro → scope='khaliqgant', name_slug='nextjs-pro'
// - nextjs-pro → scope='collection', name_slug='nextjs-pro'

const matchWithScope = collectionSpec.match(/^@?([^/]+)\/([^/@]+)(?:@(.+))?$/);
if (matchWithScope) {
  [, scope, name_slug, version] = matchWithScope;
} else {
  // No scope: default to 'collection'
  [, name_slug, version] = collectionSpec.match(/^([^/@]+)(?:@(.+))?$/);
  scope = 'collection';
}

Version Resolution

Collections support semantic versioning:

# Latest version (default)
prpm install collections/nextjs-pro

# Specific version
prpm install collections/nextjs-pro@2.0.4

# With scope and version
prpm install khaliqgant/nextjs-pro@2.0.4

Registry Behavior:

• Without version: Returns latest (most recent created_at)
• With version: Exact match required

Discovery Prioritization

When searching across all scopes (collections/* format), the system prioritizes:

1. Official Collections (official = true)

   • Curated by PRPM maintainers
   • Highest trust level

2. Verified Authors (verified = true)

   • Known community contributors
   • GitHub verified

3. Download Count (downloads DESC)

   • Most popular collections
   • Community validation

4. Recency (created_at DESC)

   • Latest versions
   • Actively maintained

Error Handling

Collection Not Found:

prpm install collections/nonexistent
# ❌ Failed to install collection: Collection not found

Scope-Specific Not Found:

prpm install wrongscope/nextjs-pro
# ❌ Failed to install collection: Collection not found
# Suggestion: Try 'collections/nextjs-pro' to search all scopes

Collection Best Practices

1. Required vs Optional: Clearly mark essential vs nice-to-have packages
2. Reason Documentation: Every package explains why it's included
3. IDE-Specific Variants: Different packages per editor when needed
4. Installation Order: Consider dependencies
5. Scope Naming:
   • Use your username/org as scope for personal collections
   • Reserve "collection" scope for official PRPM collections
6. User-Friendly IDs: Use descriptive slugs (e.g., "nextjs-pro" not "np-setup")
7. Version Incrementing: Bump versions on meaningful changes (follow semver)

• GitHub OAuth: Authentication provider
• Docker: Containerized deployment

Testing

• Vitest: Unit and integration tests
• 100% Coverage Goal: Especially for format converters
• Round-Trip Tests: Ensure conversion quality
• Fixtures: Real-world package examples

Testing Standards

Test Pyramid

• 70% Unit Tests: Format converters, parsers, utilities
• 20% Integration Tests: API routes, database operations, CLI commands
• 10% E2E Tests: Full workflows (install, publish, search)

Coverage Goals

• Format Converters: 100% coverage (critical path)
• CLI Commands: 90% coverage
• API Routes: 85% coverage
• Utilities: 90% coverage

Key Testing Patterns

// Format converter test
describe('toCursor', () => {
  it('preserves data in roundtrip', () => {
    const result = toCursor(canonical);
    const back = fromCursor(result.content);
    expect(back).toEqual(canonical);
  });
});

// CLI command test
describe('install', () => {
  it('downloads and installs package', async () => {
    await handleInstall('test-pkg', { as: 'cursor' });
    expect(fs.existsSync('.cursor/rules/test-pkg.md')).toBe(true);
  });
});

Development Workflow

Package Manager: npm (NOT pnpm)

⚠️ CRITICAL: PRPM uses npm, not pnpm ⚠️

• Lock file: package-lock.json (npm)
• Install dependencies: npm install
• Run scripts: npm run <script>
• Workspace commands: npm run <script> --workspace=<package>

DO NOT use pnpm:

• The repository has package-lock.json, not pnpm-lock.yaml
• Using pnpm will create conflicts and inconsistencies
• CI/CD uses npm for builds and deployments
• All documentation assumes npm

Common commands:

# Install all dependencies
npm install

# Install in specific workspace
npm install --workspace=@pr-pm/cli

# Run tests
npm test

# Build all packages
npm run build

# Run CLI locally
npm run dev --workspace=prpm

When Adding Features

1. Check Existing Patterns: Look at similar commands/routes
2. Update Types First: TypeScript interfaces drive implementation
3. Write Tests: Create test fixtures and cases
4. Document: Update README and relevant docs
5. Environment Variables: If adding new env vars, update .env.example immediately
6. Telemetry: Add tracking for new commands (with privacy)

When Fixing Bugs

1. Write Failing Test: Reproduce the bug in a test
2. Fix Minimally: Smallest change that fixes the issue
3. Check Round-Trip: Ensure conversions still work
4. Update Fixtures: Add bug case to test fixtures

Dependency Management Best Practices

AVOID Runtime Dependencies (Dynamic Imports)

❌ Bad: Using dynamic imports for runtime dependencies

// BAD - tar-stream is imported dynamically at runtime
const tarStream = await import('tar-stream');

Problems with Dynamic Imports:

1. Module Resolution Failures: In production (Elastic Beanstalk, Docker), dynamic imports can fail to resolve even if the package is installed as a transitive dependency
2. Build Complexity: TypeScript compilation doesn't validate dynamic imports
3. Deployment Issues: Package may not be in the module resolution path in production
4. Harder to Debug: Failures happen at runtime, not at build time

✅ Good: Declare all dependencies explicitly

// GOOD - Import normally at the top
import * as tarStream from 'tar-stream';

Dependency Guidelines:

1. Explicit Dependencies: Always declare dependencies in package.json, never rely on transitive dependencies
2. Static Imports: Use static imports whenever possible for compile-time validation
3. Production Dependencies: If you import it, it should be in dependencies, not devDependencies
4. Build-Time Validation: Let TypeScript catch missing dependencies at build time, not runtime

Environment Variable Management

ALWAYS Update .env.example When Adding New Environment Variables

Environment variables are configuration points. When adding new ones, follow this checklist:

1. Add to .env.example immediately - Don't wait until later
2. Group logically - Place in appropriate section (DATABASE, AUTH, etc.)
3. Add clear comments - Explain what it does and where to get values
4. Include examples - Show format (e.g., sk-ant-api03-... for API keys)
5. Mark optional vs required - Comment out optional variables with #
6. Update production notes - Add to deployment checklist if needed

Example:

# ==============================================================================
# NEW FEATURE SECTION
# ==============================================================================

# Description of what this variable does
# Get from: https://where-to-get-it.com
NEW_FEATURE_API_KEY=your-key-here

# Optional feature flag (default: false)
# ENABLE_NEW_FEATURE=true

Why this matters:

• New developers need to know what env vars to set
• .env.example is the source of truth for configuration
• Missing env vars cause runtime errors that are hard to debug
• Production deployments fail without proper env var documentation

Finding missing env vars:

# Search for all process.env usage
grep -rh "process.env\." packages/ --include="*.ts" --include="*.tsx" | \
  grep -o "process\.env\.[A-Z_][A-Z0-9_]*" | sort -u

# Compare with .env.example to find gaps

When Designing APIs

• REST Best Practices: Proper HTTP methods and status codes
• Versioning: All routes under /api/v1/
• Pagination: Limit/offset for list endpoints
• Filtering: Support query params for filtering
• OpenAPI: Document with Swagger/OpenAPI specs

Security Standards

• No Secrets in DB: Never store GitHub tokens, use session IDs
• SQL Injection: Parameterized queries only
• Rate Limiting: Prevent abuse of registry API
• Content Security: Validate package contents before publishing

Performance Considerations

• Batch Operations: Use Promise.all for independent operations
• Database Indexes: GIN for full-text, B-tree for lookups
• Caching Strategy: Cache converted packages, not raw data
• Lazy Loading: Don't load full package data until needed
• Connection Pooling: Reuse PostgreSQL connections

Deployment

AWS Infrastructure

Registry Backend (Elastic Beanstalk)

• Environment: Node.js 20 on 64bit Amazon Linux 2023
• Instance: t3.micro (cost-optimized)
• Database: RDS PostgreSQL
• Cache: ElastiCache Redis
• DNS: Route 53
• SSL: ACM certificates

Webapp (S3 Static Export) ⚠️ CRITICAL

The webapp MUST be deployable as a static site via S3/CloudFront.

Requirements:

• Next.js with output: 'export' configuration
• NO server-side rendering (SSR) - all pages must be static or client-side rendered
• NO API routes - all API calls go to the registry backend
• Dynamic routes require generateStaticParams() - return empty array [] for client-side only routes
• All data fetching must be client-side (useEffect, fetch, etc.)

Common Issues:

1. Dynamic routes in client components ⚠️ CANNOT USE BOTH

   • Error: Page "page" cannot use both "use client" and export function "generateStaticParams()"
   • Solution: Use query strings instead of path parameters
   • ❌ Wrong: /playground/shared/[token]/page.tsx with 'use client'
   • ✅ Correct: /playground/shared/page.tsx with ?token=xxx query param
   • Implementation: Use useSearchParams() instead of useParams()
   • IMPORTANT: Must wrap useSearchParams() in <Suspense> boundary
   • Example:

     // ❌ Dynamic route (doesn't work with 'use client')
     // /app/shared/[token]/page.tsx
     const params = useParams();
     const token = params.token;
     
     // ✅ Query string with Suspense (works with 'use client')
     // /app/shared/page.tsx
     import { Suspense } from 'react';
     
     function Content() {
       const searchParams = useSearchParams();
       const token = searchParams.get('token');
       // ... component logic
     }
     
     export default function Page() {
       return (
         <Suspense fallback={<div>Loading...</div>}>
           <Content />
         </Suspense>
       );
     }
     

2. Server components in static export

   • All pages with dynamic content must use 'use client' directive
   • Shared session pages, playground interfaces, etc. are client-rendered

3. Environment variables

   • Build-time: Embedded in static bundle (public/exposed)
   • Runtime: Fetched via API from registry backend

Why S3 Static Export?

• Cost: $0.023/GB vs $30+/month for server hosting
• Scale: CloudFront CDN handles traffic spikes
• Reliability: No server maintenance or downtime
• Performance: Pre-rendered static pages are instant

GitHub Actions Workflows

• Test & Deploy: Runs on push to main
• NPM Publish: Manual trigger for releases
• Homebrew Publish: Updates tap formula
• Webapp Deploy: Builds static export and deploys to S3

Publishing PRPM to NPM

Publishable Packages:

• prpm - CLI (public)
• @prpm/registry-client - HTTP client (public)
• Registry and Infra are private (deployed, not published)

Process:

1. Go to Actions → NPM Publish
2. Select version bump (patch/minor/major)
3. Choose packages (all or specific)
4. Run workflow

Homebrew Formula:

• Formula repository: khaliqgant/homebrew-prpm
• Auto-updates on NPM publish
• Requires HOMEBREW_TAP_TOKEN secret

Version Bumping:

# CLI and client together
npm version patch --workspace=prpm --workspace=@prpm/registry-client

# Individual package
npm version minor --workspace=prpm

Publish Command Troubleshooting

The publish command is a complex flow. Common issues and fixes:

Build Order for Publishing:

# Always build in dependency order
npm run build --workspace=@pr-pm/types
npm run build --workspace=@pr-pm/converters
npm run build --workspace=@pr-pm/registry-client
npm run build --workspace=prpm

Pre-Publish Checklist:

1. ✅ All tests pass: npm test
2. ✅ Types compile: npm run typecheck
3. ✅ Build succeeds: npm run build
4. ✅ Version bumped in all affected packages
5. ✅ Schemas copied to dist (for CLI)
6. ✅ No uncommitted changes

Debugging Publish Issues:

# Check what will be published
npm pack --workspace=prpm --dry-run

# Verify package contents
tar -tzf prpm-*.tgz

# Check for missing exports
node -e "console.log(require('./packages/cli/dist/index.js'))"

Common Patterns

CLI Command Structure

export async function handleCommand(args: Args, options: Options) {
  const startTime = Date.now();
  try {
    const config = await loadUserConfig();
    const client = getRegistryClient(config);
    const result = await client.fetchData();
    console.log('✅ Success');
    await telemetry.track({ command: 'name', success: true });
  } catch (error) {
    console.error('❌ Failed:', error.message);
    await telemetry.track({ command: 'name', success: false });
    process.exit(1);
  }
}

CLI Error Handling Pattern

Use CLIError instead of process.exit() for testable CLI errors.

// ❌ BAD - Untestable, tests can't catch process.exit()
if (!packageId) {
  console.error('Package ID is required');
  process.exit(1);
}

// ✅ GOOD - Testable with CLIError
import { CLIError } from '../utils/cli-error.js';

if (!packageId) {
  throw new CLIError('Package ID is required', { exitCode: 1 });
}

Why CLIError?

• Tests can catch and verify error conditions
• Consistent error formatting across CLI
• Exit codes are explicit and documented
• Enables reliable CI testing (PR #110 refactor)

CLIError Usage:

import { CLIError, createError, createSuccess } from '../utils/cli-error.js';

// Simple error
throw new CLIError('Something went wrong');

// With exit code
throw new CLIError('Invalid format specified', { exitCode: 1 });

// With suggestions
throw new CLIError('Package not found', {
  exitCode: 1,
  suggestion: 'Try running: prpm search <query>'
});

// Helper functions for consistent messaging
createError('Operation failed');     // Returns formatted error
createSuccess('Package installed'); // Returns formatted success

Testing CLI Errors:

import { describe, it, expect } from 'vitest';
import { CLIError } from '../utils/cli-error.js';

describe('install command', () => {
  it('throws CLIError for missing package', async () => {
    await expect(handleInstall('')).rejects.toThrow(CLIError);
  });

  it('provides helpful error message', async () => {
    try {
      await handleInstall('');
    } catch (error) {
      expect(error).toBeInstanceOf(CLIError);
      expect(error.message).toContain('Package ID is required');
    }
  });
});

Registry Route Structure

server.get('/:id', {
  schema: { /* OpenAPI schema */ },
}, async (request, reply) => {
  const { id } = request.params;
  if (!id) return reply.code(400).send({ error: 'Missing ID' });
  const result = await server.pg.query('SELECT...');
  return result.rows[0];
});

Format Converter Structure

export function toFormat(pkg: CanonicalPackage): ConversionResult {
  const warnings: string[] = [];
  let qualityScore = 100;
  const content = convertSections(pkg.content.sections, warnings);
  const lossyConversion = warnings.some(w => w.includes('not supported'));
  if (lossyConversion) qualityScore -= 10;
  return { content, format: 'target', warnings, qualityScore, lossyConversion };
}

Naming Conventions

• Files: kebab-case (registry-client.ts, to-cursor.ts)
• Types: PascalCase (CanonicalPackage, ConversionResult)
• Functions: camelCase (getPackage, convertToFormat)
• Constants: UPPER_SNAKE_CASE (DEFAULT_REGISTRY_URL)
• Database: snake_case (package_id, created_at)
• API Requests/Responses: snake_case (package_id, session_id, created_at)
  • Important: All API request and response fields use snake_case to match PostgreSQL database conventions
  • Internal service methods may use camelCase, but must convert to snake_case at API boundaries
  • TypeScript interfaces for API types should use snake_case fields
  • Examples: PlaygroundRunRequest.package_id, CreditBalance.reset_at

Documentation Standards

• Inline Comments: Explain WHY, not WHAT
• JSDoc: Required for public APIs
• README: Keep examples up-to-date
• Markdown Docs: Use code blocks with language tags
• Changelog: Follow Keep a Changelog format
• Continuous Accuracy: Documentation must be continuously updated and tended to for accuracy
  • When adding features, update relevant docs immediately
  • When fixing bugs, check if docs need corrections
  • When refactoring, verify examples still work
  • Review docs quarterly for outdated information
  • Keep CLI docs, README, and Mintlify docs in sync
