crew-opencode Implementation Plan

Overview

Build an OpenCode plugin called crew-opencode that provides multi-agent orchestration with a professional crew of specialized agents, using TypeScript + Bun runtime.

"Low-cost tasks to affordable agents; high-level reasoning to top-tier models."

Core Philosophy

  1. Cost-Effective: Simple, repetitive tasks are delegated to lightweight models, while complex reasoning is reserved for high-performance models.
  2. Specialization: Rather than relying on generalists who do "everything," we aim for expert agents specialized in their specific Roles.
  3. Accountability: When a task fails, a clear root cause analysis (The Apology Letter) is mandatory to prevent recurrence.

Requirements

  • Multi-agent orchestration with cost-optimized model selection
  • Role-based crew: PM, TA, FE, Design, QA
  • crew command system with structured SOPs
  • Automated Incident Reports ("Apology Letter") for error handling
  • TypeScript + Bun runtime for modern, fast execution
  • Installable via bunx crew-opencode install
  • Compatible with OpenCode's plugin system

The Crew

Role Position Model Description
PM Project Manager Opus 4.5 Coordinates parallel team members (agents). Manages product strategy, determines priorities, and executes plans.
TA Technical Analyst Claude Sonnet 4.5 Conducts research on official documentation and open-source implementations, performs deep analysis of the codebase.
FE UI/UX Engineer Gemini 3 Pro Develops frontend logic and implements user interfaces reflecting the latest trends.
Design Designer GPT 5.2 Medium Reviews UI/UX flows and proposes design systems.
QA Quality Assurance Claude Haiku 4.5 Performs Unit Tests and E2E tests to verify stability and analyze quality.

📝 Notes

Implementation Notes

  1. LLM Integration Strategy:

    • Start with Anthropic API (most critical for PM/TA/QA)
    • Add OpenAI and Google APIs in parallel
    • Use environment variables for API keys
    • Add graceful fallbacks if API unavailable

  2. Testing Strategy:

    • Write tests incrementally with each feature
    • Focus on core modules first (orchestrator, task-queue)
    • Use mocks for LLM API calls in tests
    • Add integration tests last

  3. Performance Considerations:

    • Context summarization between agent handoffs
    • Parallel task execution where possible
    • Cache configuration and agent metadata
    • Stream LLM responses for progress indication

  4. Security Considerations:

    • Never log API keys or sensitive data
    • Validate all user inputs
    • Sanitize file paths
    • Rate limit API calls to prevent abuse

Design Decisions

  1. Why Bun?

    • Fast runtime and bundler
    • Native TypeScript support
    • Great developer experience
    • Easy standalone binary builds

  2. Why Zod?

    • Runtime type validation
    • Type inference for TypeScript
    • Great error messages
    • Widely adopted

  3. Why Markdown for Agents/SOPs?

    • Easy to read and edit
    • Version control friendly
    • Can embed in prompts directly
    • Human and machine readable

  4. Why File-based Config?

    • Portable across projects
    • Version control friendly
    • Easy to share with team
    • Standard JSON format

Lessons Learned

  1. Multi-agent Coordination:

    • Strict SOPs prevent agent deviation
    • Context summarization is essential
    • Parallel execution needs careful dependency management
    • Incident reports improve reliability

  2. Cost Optimization:
