## 🤖 About This Project
<div align="center">
### ⚡ This project was 100% autonomously built by AI ⚡
**Z.AI GLM-5** created this entire codebase in a single session — designing the architecture,
implementing all modules, writing comprehensive documentation, packaging the releases,
and even pushing everything to this Git repository.
**[Learn more about Z.AI GLM-5 →](https://z.ai/subscribe?ic=R0K78RJKNW)**
*Yes, the README you're reading right now was written by the AI too! 🎉*
</div>
---
## Overview
This project provides two complementary systems:
1. **Agent System** - Context compaction, token management, and agent orchestration
2. **Pipeline System** - Deterministic state machine, parallel execution, and event-driven coordination
Built based on the architectural principles described in [How I Built a Deterministic Multi-Agent Dev Pipeline Inside OpenClaw](https://dev.to/ggondim/how-i-built-a-deterministic-multi-agent-dev-pipeline-inside-openclaw-and-contributed-a-missing-4ool).
---
## Features
### Agent System
-**Token Counting & Management** - Accurate token estimation with budget tracking
-**Context Compaction** - 4 strategies: sliding-window, summarize-old, priority-retention, hybrid
-**Conversation Summarization** - LLM-powered summarization with key points extraction
-**Agent Orchestration** - Lifecycle management, task routing, event handling
-**Subagent Spawning** - 6 predefined subagent types for task delegation
-**Persistent Storage** - File-based memory store for agent state
-**Claude Code Integration** - Full support for Claude Code CLI/IDE
-**OpenClaw Integration** - Native integration with OpenClaw workflows
### Pipeline System
-**Deterministic State Machine** - Flow control without LLM decisions

## Quick Start
### Agent System
```typescript
import { ContextManager, TokenCounter, Summarizer } from './agent-system';
// Initialize components
const tokenCounter = new TokenCounter(128000); // 128k token budget
const summarizer = new Summarizer();
const contextManager = new ContextManager(tokenCounter, summarizer, {
maxTokens: 100000,
compactionStrategy: 'hybrid',
reserveTokens: 20000
});
// Add messages
contextManager.addMessage({ role: 'user', content: 'Hello!' });
contextManager.addMessage({ role: 'assistant', content: 'Hi there!' });
// Check if compaction needed
if (contextManager.needsCompaction()) {
const result = await contextManager.compact();
console.log(`Compacted: ${result.messagesRemoved} messages removed`);
}
```
### Pipeline System
```typescript
import { DeterministicStateMachine, ParallelExecutionEngine, EventBus } from './pipeline-system';
// Define workflow
const workflow = `
name: code-pipeline
states:
- name: analyze
transitions:
- to: implement
event: analyzed
- name: implement
transitions:
- to: test
event: implemented
- name: test
transitions:
- to: complete
event: passed
`;
// Create pipeline
const eventBus = new EventBus();
const stateMachine = new DeterministicStateMachine(workflow);
const executor = new ParallelExecutionEngine({ maxConcurrency: 4 });
// Run pipeline
await stateMachine.start();
```
---
## Integrations
### Claude Code Integration
Full integration with Claude Code CLI and IDE extensions:
```typescript
import { ClaudeCodeIntegration } from './agent-system/integrations/claude-code';
// Initialize with Claude Code defaults
const claude = new ClaudeCodeIntegration({
maxContextTokens: 200000, // Claude's context window
reserveTokens: 40000, // Reserve for response
compactionStrategy: 'hybrid',
autoCompact: true,
compactionThreshold: 0.8,
enableSubagents: true,
maxSubagents: 6,
persistentMemory: true
});
// Add messages with automatic compaction
claude.addMessage({ role: 'user', content: 'Analyze this codebase...' });
// Get context for Claude API
const { messages, systemPrompt } = claude.getContextForAPI();
// Spawn subagents for complex tasks
const result = await claude.spawnSubagent({
type: 'researcher',
prompt: 'Research authentication patterns',
priority: 'high'
});
// Parallel subagent execution (4 projects × 3 roles pattern)
const results = await claude.executeParallelSubagents([
{ type: 'explorer', prompt: 'Find security issues in frontend' },
{ type: 'explorer', prompt: 'Find security issues in backend' },
{ type: 'reviewer', prompt: 'Review API endpoints' }
]);
// Memory management
await claude.remember('userPreference', { theme: 'dark' });
const pref = await claude.recall('userPreference');
// Save/restore context
await claude.saveContext('milestone-1');
await claude.loadContext('milestone-1');
// Monitor session
const stats = claude.getTokenStats();
console.log(`Using ${stats.percentage}% of context (${stats.used}/${stats.total} tokens)`);
```
### OpenClaw Integration
Native integration with OpenClaw's deterministic multi-agent architecture:
```typescript
import { OpenClawIntegration } from './agent-system/integrations/openclaw';
// Initialize with OpenClaw-compatible config
const openclaw = new OpenClawIntegration({
maxContextTokens: 200000,
compactionStrategy: 'hybrid',
workspaceIsolation: true,
enableLobsterWorkflows: true,
enableParallelExecution: true,
maxParallelAgents: 12, // 4 projects × 3 roles
hooks: {
onCompactionStart: (ctx) => console.log('Compacting...'),
onCompactionEnd: (result) => console.log(`Saved ${result.tokensSaved} tokens`),
onStateTransition: (from, to, ctx) => console.log(`${from}${to}`)
}
});
// Add messages with OpenClaw context
openclaw.addMessage({
role: 'user',
content: 'Implement user authentication',
tags: ['feature', 'auth'],
references: {
files: ['src/auth.ts', 'src/middleware.ts']
}
});
// Spawn agents for parallel execution
const agents = await openclaw.executeParallelAgents([
{ type: 'planner', prompt: 'Plan auth architecture' },
{ type: 'researcher', prompt: 'Research JWT best practices' },
{ type: 'explorer', prompt: 'Find existing auth patterns' }
]);
// Create deterministic pipeline
const pipeline = openclaw.createPipeline({
name: 'feature-development',
description: 'Complete feature development workflow',
states: [
{
name: 'analyze',
type: 'parallel',
agents: ['explorer', 'researcher'],
transitions: [
{ target: 'design', event: 'analysis_complete' }
]
},
{
name: 'design',
type: 'sequential',
agents: ['planner'],
transitions: [
{ target: 'implement', event: 'design_approved' }
]
},
{
name: 'implement',
type: 'parallel',
agents: ['coder'],
transitions: [
{ target: 'review', event: 'implementation_complete' }
]
},
{
name: 'review',
type: 'sequential',
agents: ['reviewer'],
transitions: [
{ target: 'complete', event: 'approved' },
{ target: 'implement', event: 'rejected' }
]
},
{
name: 'complete',
type: 'sequential',
transitions: []
}
]
});
// Execute pipeline
await openclaw.startPipeline(pipeline.id);
await openclaw.transitionPipeline(pipeline.id, 'analysis_complete');
await openclaw.transitionPipeline(pipeline.id, 'design_approved');
// ... continue transitions
// Create isolated workspaces
const workspace = await openclaw.createWorkspace({
permissions: ['read', 'write'],
quota: { maxFiles: 1000, maxSize: 100 * 1024 * 1024 }
});
```

## Compaction Strategies
### 1. Sliding Window
Keeps the most recent N messages:
```typescript
const contextManager = new ContextManager(tokenCounter, summarizer, {
compactionStrategy: 'sliding-window',
slidingWindowSize: 50 // Keep last 50 messages
});
```
### 2. Summarize Old
Summarizes older messages into a compact summary:
```typescript
const contextManager = new ContextManager(tokenCounter, summarizer, {
compactionStrategy: 'summarize-old',
preserveRecentCount: 10 // Keep last 10 messages verbatim
});
```
### 3. Priority Retention
Keeps messages containing priority keywords:
```typescript
const contextManager = new ContextManager(tokenCounter, summarizer, {
compactionStrategy: 'priority-retention',
priorityKeywords: ['error', 'important', 'decision', 'critical']
});
```
### 4. Hybrid (Recommended)
Combines all strategies for optimal results:
```typescript
const contextManager = new ContextManager(tokenCounter, summarizer, {
compactionStrategy: 'hybrid',
slidingWindowSize: 30,
preserveRecentCount: 10,
priorityKeywords: ['error', 'important', 'decision']
});
```

*
* ## Key Principles
*
* 1. **Deterministic Flow**: State machines control the pipeline, not LLM decisions
* 2. **Event-Driven**: Agents communicate through events, enabling loose coupling
* 3. **Parallel Execution**: Multiple agents work concurrently with resource isolation
* 4. **Workspace Isolation**: Each agent has its own tools, memory, and file space
* 5. **YAML Workflows**: Define pipelines declaratively, compatible with Lobster
