bobs workshop - agentic dev harness for OpenCode

using well-stitched OpenCode features for MANUAL-driven development with background agents, to stop juggling between sequential agent calls, scattered context, and endless context switching

Problem statement

you know that feeling when you're deep in a complex feature or when the codebase gets large after adding a few features, and you have to:
- explain your entire codebase ... again
- switch between architecture planning and implementation
- keep track of decisions made 3 conversations ago
- run agents sequentially when they could work in parallel

What if your AI agents could talk to each other, work in parallel, and build lasting knowledge about your project through shared markdown files (MANUALS)?

What makes this different

📝 MANUALs that live: Documentation that updates as you build through shared specifications
🧠 Agents that remember: Your project context persists across conversations via MANUAL files
🔄 Workflows that connect: Alice → Bob → Trace workflow in one flow
⚡ Parallel execution: Multiple background agents work simultaneously on different tasks
🎯 Verification built-in: PASS/FAIL verification with Bob ensures quality

🔧 Solution overview

MANUAL-driven development methodology: Every feature begins with a comprehensive MANUAL that serves as the single source of truth. This approach ensures architectural consistency and eliminates the traditional disconnect between planning and implementation.

Background execution architecture: Agents run as background tasks, allowing you to continue working while they complete their work. Multiple agents can run simultaneously, dramatically reducing development time through parallel exploration and implementation.

Context persistence through MANUALs: Project knowledge accumulates across conversations through MANUAL files. Unlike traditional AI interactions that lose context, agents build cumulative understanding of your codebase patterns, architectural decisions, and implementation preferences by reading and updating the same MANUAL.

Multi-agent coordination system: Four specialized AI agents work collaboratively within shared MANUAL documents. Alice (architect) plans and coordinates parallel exploration, Bob (orchestrator) implements with skills-based delegation, Bob-Rev (reviewer) provides PASS/FAIL verification, and Bob-Send (shipper) handles build, lint, test, and verification.

Plugin-based tool integration: Six custom tools provide seamless background task management. background_agent launches parallel tasks, background_output collects results, background_cancel manages cleanup, manual_update appends to MANUAL sections, verify_manual runs automated verification, and list_background_tasks provides observability.

🎯 Use cases

- Feature Development: End-to-end feature planning, implementation, and verification with MANUALs
- Architecture Analysis: Deep codebase exploration with parallel agent coordination
- Code Review: Multi-perspective code analysis with specialized review skills
- Documentation: MANUAL-driven documentation generation and maintenance
- Research: Best practice research and technology evaluation through parallel exploration
- Project Planning: Specification-driven development planning with living MANUALs

🏗️ Architecture

Bob's Workshop integrates with OpenCode through:

- Plugin System: Custom tools extend OpenCode's capabilities
- Agent Framework: Five specialized agents for different development phases
- Skill System: Sixteen specialized skills for specific expertise
- Background Execution: Parallel task management without blocking

📦 Components
