description	Add a new AI provider to agentconfig.org's comparison system. Use when integrating a new coding assistant (e.g., Cursor, Claude Desktop, GitHub Copilot alternative) with proper type system updates, implementation data, UI components, tests, and documentation. Use when this capability is needed.

Add Provider

Add a new AI coding assistant provider to agentconfig.org's provider comparison system.

Overview

Adding a provider requires coordinated work across 6 parallel work streams:

Stream	Work	Duration	Dependencies
1. Type System	Add provider to union types	2-4 hrs	None
2. Data Layer	Add implementations for all 11 primitives	4-6 hrs	Stream 1
3. UI Components	Update comparison table	4-8 hrs	Streams 1-2
4. Testing	Update E2E tests	3-4 hrs	Stream 3
5. App Integration	Update site copy & docs	1-2 hrs	Streams 1-3
6. LLMs Generation	Regenerate machine-readable files	1-2 hrs	All streams

Total effort: ~2-3 hours with parallelization

When to Use

Use this skill when:

• Integrating a new coding assistant (Cursor, Claude Desktop, Zed with AI, etc.)
• Expanding provider support beyond current offerings
• The provider implements most of the 11 AI primitives
• You want comprehensive comparison data visible to users and AI agents

Prerequisites

Before starting, gather:

• Provider capability audit - Which of the 11 primitives does the provider support?
• File path documentation - Where do config files go (global vs project)?
• Support levels - full (native), partial (workarounds), none (unavailable), diy (custom setup)

The 11 Primitives

Every provider must map to these primitives:

Category	Primitives
Execution	Agent Mode, Skills/Workflows, Tool Integrations (MCP)
Customization	Persistent Instructions, Global Instructions, Path-Scoped Rules, Slash Commands
Control	Custom Agents, Permissions & Guardrails, Lifecycle Hooks, Verification/Evals

Quick Start

0. 🔍 Research the provider → See RESEARCH-GUIDE.md for capability audit template

   • Visit official documentation
   • Document support level for each of the 11 primitives
   • Verify config file locations
   • Complete this BEFORE writing any code (see pre-implementation checklist in CHECKLIST.md)

1. 📋 Read the detailed process → See PROCESS.md for step-by-step instructions for all 6 streams

2. 📖 Review code examples → See EXAMPLES.md for copy-paste templates for each stream

3. 🎨 Understand patterns → See PATTERNS.md for support levels and naming conventions

4. 🐛 Handle errors → See ERRORS.md for solutions to common issues (including critical generation script updates)

5. ✅ Verify completion → See CHECKLIST.md for verification steps (includes pre-implementation checklist)

6-Stream Workflow at a Glance

Stream 1: Type System (Add provider to union types)
   ↓
Stream 2: Data Layer (Add implementations for all 11 primitives)
   ├→ Stream 3: UI Components (Update comparison table)
   │    ↓
   │  Stream 4: Testing (Update E2E tests)
   │    ↓
   └→ Stream 5: App Integration (Update site copy/docs) [can run in parallel with 3-4]
        ↓
      Stream 6: LLMs Generation (Regenerate machine-readable files)

Parallel execution: Start Stream 5 while Streams 3-4 complete. Stream 1-2 are sequential. Stream 6 must run last.

Key Files to Modify

Stream	Files
1	site/src/data/primitives.ts, site/src/data/fileTree.ts, site/src/data/comparison.ts, site/src/components/PrimitiveCards/PrimitiveCard.tsx
2	site/src/data/primitives.ts, site/src/data/comparison.ts, site/src/data/fileTree.ts
3	site/src/components/ProviderComparison/ComparisonTable.tsx
4	site/tests/e2e/comparison.spec.ts
5	site/src/App.tsx, site/src/components/Hero/Hero.tsx, README.md
6	.github/skills/generate-llms/scripts/generate-llms-full.ts (if needed), site/public/llms-full.txt

Example Prompts

Add a new provider from scratch:

Use the add-provider skill to add Cursor as a provider to agentconfig.org.
Research Cursor's implementation of all 11 primitives first, then follow all 6 streams.

Skip to a specific stream:

I've completed Stream 1 (types). Now execute Stream 2 (data layer) to add cursor implementations.

Update existing provider data:

Update Cursor's support level from partial to full for Tool Integrations in the comparison.ts and UI.

Success Metrics

✅ Provider added to all type definitions ✅ All 11 primitives have provider implementation data ✅ Comparison table renders with provider column ✅ All E2E tests pass ✅ No TypeScript errors ✅ Production build succeeds ✅ llms-full.txt includes provider data ✅ Responsive design works ✅ Dark mode works

PR Description Best Practices

When opening your pull request, keep it crisp and focused:

What to include:

• Summary: One sentence—what provider, what changed
• Changes: Organized by stream (Types, Data, UI, Tests, Integration, Docs)
• Result: Quick summary of provider's final support coverage
• Testing: Concrete steps to verify (run commands, visit site, click features)
• References: Link to official provider documentation as sources

What to avoid:

• Listing all 11 primitives exhaustively
• Repetitive narrative about each stream
• Verbose technical implementation details

Example: See Cursor provider PR for a reference implementation.
