Synapse AI Agent Orchestration Skill

Synapse is a distributed AI agent system that orchestrates three specialized services with configurable models and role-based workflows.

Agent Roles

| Agent | Role | Capabilities | Default Model | |-------|------|--------------|---------------| | Claude | Orchestrator/Planner | Task planning, architecture design, code generation | claude-sonnet-4.5 | | Gemini | Analyst/Reviewer | Large context analysis (>1M tokens), code review, security audits | gemini-3-pro-preview | | Codex | Executor | Command execution, build processes, automated testing | gpt-5.2 |

When to Apply

Use this skill when:

  • Breaking down complex tasks into actionable multi-step plans
  • Generating implementation code from descriptions or specifications
  • Analyzing large codebases or content (especially >200k tokens via Gemini)
  • Getting comprehensive code reviews with quality scoring
  • Running sandboxed shell commands for builds, tests, or automation
  • Executing full plan-analyze-code-review-execute workflows
  • Orchestrating parallel or pipeline-based multi-agent workflows

Do NOT use when:

  • Simple questions that don't require code generation
  • Tasks that only need local file operations
  • When Docker/Synapse services are not available

Prerequisites

Docker must be running with Synapse services active.

# Clone Synapse (if not already)
git clone https://github.com/akillness/Synapse.git ~/Synapse
cd ~/Synapse

# Start services
docker compose up -d

# Verify all services are healthy
curl -s http://localhost:8000/health
# Expected: {"status": "healthy", "service": "gateway"}

Installation

Global Installation (Recommended)

# Clone synapse-skill
git clone https://github.com/akillness/synapse-skill.git

# For OpenCode
ln -s $(pwd)/synapse-skill ~/.config/opencode/skills/synapse

# For Claude Code / Other Agents
mkdir -p ~/.agents/skills
ln -s $(pwd)/synapse-skill ~/.agents/skills/synapse

Environment Variables (Optional)

# Custom Synapse location
export SYNAPSE_HOME="$HOME/Synapse"

# Gateway URL (default: http://localhost:8000)
export SYNAPSE_GATEWAY_URL="http://localhost:8000"

For Cursor IDE

Create .cursor/rules/synapse.mdc in your project:

---
description: Synapse AI Agent Orchestration
globs: ["**/*"]
alwaysApply: true
---

# Synapse Skill Integration

When orchestrating multi-agent tasks, use Synapse endpoints:
- Plan: POST http://localhost:8000/api/v1/claude/plan
- Code: POST http://localhost:8000/api/v1/claude/code
- Analyze: POST http://localhost:8000/api/v1/gemini/analyze
- Review: POST http://localhost:8000/api/v1/gemini/review
- Execute: POST http://localhost:8000/api/v1/codex/execute

Use @planner for task breakdown, @reviewer for code review.

For Claude Code (CLAUDE.md)

Add to your ~/.claude/CLAUDE.md:

## Synapse Integration

For multi-agent orchestration, use Synapse skill:
- Health check: curl http://localhost:8000/health
- Ensure Docker containers are running: docker ps | grep synaps
- Use /api/v1/workflow for full pipeline execution

For OpenCode (oh-my-opencode.json)

Add Synapse-optimized agent configuration to ~/.config/opencode/oh-my-opencode.json:

{
  "$schema": "https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/master/assets/oh-my-opencode.schema.json",
  "agents": {
    "synapse-planner": {
      "model": "google/antigravity-claude-sonnet-4-5"
    },
    "synapse-analyst": {
      "model": "google/antigravity-gemini-3-pro-high"
    },
    "synapse-coder": {
      "model": "google/antigravity-claude-sonnet-4-5-thinking"
    },
    "synapse-reviewer": {
      "model": "google/antigravity-gemini-3-pro-high"
    },
    "synapse-executor": {
      "model": "openai/gpt-5.2-codex-high"
    }
  }
}

OpenCode Model Provider Configuration

Add to ~/.config/opencode/opencode.json for custom Synapse models:

{
  "provider": {
    "synapse": {
      "name": "Synapse Local",
      "api": "openai",
      "options": {
        "baseURL": "http://localhost:8000/api/v1/"
      },
      "models": {
        "claude-planner": {
          "name": "Claude Planner (Synapse)",
          "limit": { "context": 200000, "output": 64000 }
        },
        "gemini-analyst": {
          "name": "Gemini Analyst (Synapse)",
          "limit": { "context": 1000000, "output": 65536 }
        },
        "codex-executor": {
          "name": "Codex Executor (Synapse)",
          "limit": { "context": 272000, "output": 128000 }
        }
      }
    }
  }
}

OpenCode Skill Integration

The skill is automatically loaded when symlinked to ~/.config/opencode/skills/synapse.

Trigger phrases for OpenCode:

  • "orchestrate agents" → Activates Synapse workflow
  • "multi-agent workflow" → Starts parallel or pipeline execution
  • "run synapse" → Executes full workflow

Agentic Workflow Patterns

Pattern 1: Parallel Specialists

Multiple specialists review code simultaneously:

┌─────────────────────────────────────────────────────┐
│                    ORCHESTRATOR                      │
│                   (You / Claude)                     │
└────────────┬───────────┬───────────┬────────────────┘
             │           │           │
     ┌───────▼───┐ ┌─────▼─────┐ ┌───▼───────┐
     │ Security  │ │Performance│ │ Simplicity│
     │ Reviewer  │ │ Reviewer  │ │ Reviewer  │
     │ (Gemini)  │ │ (Gemini)  │ │ (Gemini)  │
     └───────────┘ └───────────┘ └───────────┘

Workflow:

# 1. Spawn parallel reviews
curl -X POST http://localhost:8000/api/v1/gemini/review \
  -d '{"code": "<code>", "language": "python", "review_type": "security"}'

curl -X POST http://localhost:8000/api/v1/gemini/review \
  -d '{"code": "<code>", "language": "python", "review_type": "performance"}'

curl -X POST http://localhost:8000/api/v1/gemini/review \
  -d '{"code": "<code>", "language": "python", "review_type": "simplicity"}'

# 2. Aggregate results and synthesize

Pattern 2: Pipeline (Sequential Dependencies)

Each stage depends on the previous:

┌──────────┐    ┌──────────┐    ┌──────────┐    ┌──────────┐    ┌──────────┐
│ Research │───▶│   Plan   │───▶│Implement │───▶│   Test   │───▶│  Review  │
│ (Gemini) │    │ (Claude) │    │ (Claude) │    │ (Codex)  │    │ (Gemini) │
└──────────┘    └──────────┘    └──────────┘    └──────────┘    └──────────┘

Workflow:

# Step 1: Research (Gemini analyzes requirements)
RESEARCH=$(curl -X POST http://localhost:8000/api/v1/gemini/analyze \
  -d '{"content": "<requirements>", "analysis_type": "documentation"}')

# Step 2: Plan (Claude creates implementation plan)
PLAN=$(curl -X POST http://localhost:8000/api/v1/claude/plan \
  -d "{\"task\": \"Implement based on: $RESEARCH\", \"constraints\": [\"python\", \"tests\"]}")

# Step 3: Implement (Claude generates code)
CODE=$(curl -X POST http://localhost:8000/api/v1/claude/code \
  -d "{\"description\": \"$PLAN\", \"language\": \"python\"}")

# Step 4: Test (Codex executes tests)
TEST=$(curl -X POST http://localhost:8000/api/v1/codex/execute \
  -d '{"command": "python -m pytest tests/", "timeout": 60}')

# Step 5: Review (Gemini reviews final code)
REVIEW=$(curl -X POST http://localhost:8000/api/v1/gemini/review \
  -d "{\"code\": \"$CODE\", \"language\": \"python\"}")

Pattern 3: Swarm (Self-Organizing)

Workers grab available tasks from a pool:

                    ┌─────────────┐
                    │  Task Pool  │
                    │ ┌─┬─┬─┬─┬─┐ │
                    │ │1│2│3│4│5│ │
                    │ └─┴─┴─┴─┴─┘ │
                    └──────┬──────┘
           ┌───────────────┼───────────────┐
           │               │               │
     ┌─────▼─────┐   ┌─────▼─────┐   ┌─────▼─────┐
     │  Worker 1 │   │  Worker 2 │   │  Worker 3 │
     │  (Claude) │   │  (Gemini) │   │  (Codex)  │
     │ claims #1 │   │ claims #2 │   │ claims #3 │
     └───────────┘   └───────────┘   └───────────┘

Workflow:

# Create task pool via workflow endpoint
curl -X POST http://localhost:8000/api/v1/workflow \
  -d '{
    "task": "Review all files in src/",
    "mode": "swarm",
    "workers": 3,
    "constraints": ["parallel", "auto-assign"]
  }'

Pattern 4: Full Workflow (End-to-End)

Use the workflow endpoint for automatic orchestration:

curl -X POST http://localhost:8000/api/v1/workflow \
  -H "Content-Type: application/json" \
  -d '{
    "task": "Build a user authentication module",
    "constraints": ["FastAPI", "JWT", "PostgreSQL"],
    "workflow_type": "pipeline",
    "model_config": {
      "planner": "claude-sonnet-4",
      "analyst": "gemini-2.5-pro",
      "coder": "claude-sonnet-4",
      "executor": "gpt-5.2"
    }
  }'

Integration with AI Agents

This skill can be used by any AI coding agent that supports HTTP requests:

  • OpenCode/Claude Code: Use bash tool with curl commands
  • Cursor: Use terminal or HTTP client extensions
  • GitHub Copilot: Use inline curl in terminal
  • Windsurf: Use built-in terminal

Example Agent Integration

User: "Create a plan to build a web scraper"

Agent uses Synapse skill:
1. curl POST /api/v1/claude/plan with task and model config
2. Parse response and present steps to user
3. Offer to generate code for each step
4. Execute tests via Codex
5. Review final code via Gemini

Swarm Mode Integration

For complex multi-file tasks, use swarm orchestration:

User: "Review all authentication files for security issues"

Agent orchestrates:
1. Spawn parallel Gemini reviewers for each file
2. Aggregate findings
3. Generate summary report
4. Propose fixes via Claude

Improvement Roadmap

1. Unified Workflow Endpoint Enhancement

Current: Individual service calls required

curl /api/v1/claude/plan → curl /api/v1/claude/code → curl /api/v1/gemini/review → curl /api/v1/codex/execute

Planned: Single workflow call with workflow_type parameter

curl /api/v1/workflow -d '{"task": "...", "workflow_type": "pipeline|parallel|swarm"}'

2. MCP Tool Direct Integration

Current: curl-based access via Bash tool

Bash → curl → Gateway → Service

Planned: Native MCP server tools

mcp__synapse__plan → Gateway → Claude
mcp__synapse__analyze → Gateway → Gemini
mcp__synapse__execute → Gateway → Codex

3. Enhanced Error Handling

Current: Simple error response

{"detail": "Service not ready"}

Planned: Rich error with retry guidance

{
  "error": "Service not ready",
  "retry_after": 5,
  "fallback_available": true,
  "fallback_service": "gemini-2.5-flash"
}

4. SSE Streaming Response Support

Current: Full response wait

response = await service.plan(request)  # Waits for completion

Planned: Real-time progress streaming

async for chunk in service.plan_stream(request):
    yield chunk  # Real-time progress updates

5. Redis Caching Layer

Planned Architecture:

              Request
                 │
                 ▼
          ┌─────────────┐     Cache Hit      ┌─────────────┐
          │   Gateway   │ ─────────────────▶ │    Redis    │
          └──────┬──────┘                    └─────────────┘
                 │ Cache Miss
                 ▼
          ┌─────────────┐
          │   Service   │
          └─────────────┘

6. Quick Commands (Planned)

# Shorthand commands for common operations
synapse plan "Build REST API"     # → Claude Plan
synapse review "def foo(): ..."   # → Gemini Review
synapse run "pytest tests/"       # → Codex Execute
synapse flow "Create feature X"   # → Full Pipeline

7. Auto Service Detection

Planned Features:

  • Docker container status check on skill activation
  • Automatic unhealthy service restart prompt
  • Service dependency validation
