Foundry

The forge that forges itself.

Foundry is a self-writing meta-extension for OpenClaw that learns how you work, researches documentation, and writes new capabilities into itself. It observes your workflows, crystallizes patterns into tools, and upgrades itself to match how you operate.

OpenClaw vs Foundry

OpenClaw (originally Clawdbot) is the platform — an open-source agent runtime with:

• Gateway, channels, memory, sessions
• Tool execution and skill loading
• Model providers and routing
• The infrastructure everything runs on

Foundry is a plugin that runs on OpenClaw:

• Observes how you work → learns your patterns
• Researches docs → writes new extensions/skills/hooks
• Has its own learning engine (not part of OpenClaw core)
• Can modify itself via foundry_extend_self
• Publishes to Foundry Marketplace via x402

OpenClaw (platform)
├── Gateway
├── Channels (Discord, Slack, Telegram...)
├── Skills & Tools
└── Plugins
    └── Foundry (this repo)
        ├── observes → your workflows
        ├── researches → docs, papers, repos
        ├── writes → extensions, skills, hooks
        ├── learns → from outcomes
        ├── crystallizes → patterns into tools
        └── publishes → to marketplace

Key distinction: OpenClaw doesn't have built-in self-learning. Foundry adds that capability on top. Foundry is an "agent that builds agents" — it uses OpenClaw's infrastructure to create new OpenClaw capabilities, and upgrades itself to match how you work.

Why Self-Writing Matters

The key insight isn't "LLM writes code for you" — it's "the system upgrades itself."

Knowledge vs Behavior

Knowledge (Patterns)	Behavior (Self-Written Code)
Stored as text	Baked into the system
LLM must read and apply each time	Runs automatically
Uses tokens every invocation	Zero token cost
Can be forgotten or ignored	Always executes

A pattern says: "When X happens, do Y." Self-written code does Y automatically when X happens.

Workflow Learning

Foundry tracks every workflow you run:

Goal: "deploy to staging"
Tools: git → build → test → deploy
Outcome: success
Duration: 45s

Over time, patterns emerge. When a pattern hits 5+ uses with 70%+ success rate, Foundry crystallizes it into a dedicated tool.

What took 8 tool calls now takes 1.

The Recursive Loop

Foundry observes how you work
    ↓
Learns patterns, researches docs
    ↓
Writes tool/hook to match your workflow
    ↓
That code becomes part of Foundry
    ↓
Foundry is now better at working like you
    ↓
Better Foundry learns more, writes more
    ↓
Repeat

The system that writes the code IS the code being written.

Why This Compounds

Traditional Agents	Foundry
Same logic every time	Learns your patterns
You adapt to the agent	Agent adapts to you
Each capability is isolated	Each upgrade improves the upgrader
Linear improvement	Compound improvement

Example:

• You deploy to staging 5 times using git→build→test→deploy
• Foundry recognizes the pattern (87% success rate)
• Crystallizes into deploy_staging tool
• Now "deploy to staging" is a single command
• You save time → do more deploys → pattern strengthens
• Foundry learns variations (deploy to prod, deploy with migrations)
• Loop

The Bet

Traditional software: Human improves software → software does more

Foundry: Software upgrades software → software upgrades faster

This is recursive self-improvement — each capability makes acquiring the next capability easier.

Features

Self-Writing Code Generation

• Writes OpenClaw extensions with tools and hooks
• Generates API skills following AgentSkills format with YAML frontmatter
• Generates browser automation skills with CDP integration
• Generates standalone hooks with HOOK.md + handler.ts pattern
• Can extend itself with new capabilities
• Validates code in isolated sandbox before deployment

Workflow Learning & Crystallization

• Tracks goal → tool sequence → outcome for every workflow
• Extracts keywords from goals for pattern matching
• Calculates success rates and average durations
• Crystallizes high-value patterns (5+ uses, 70%+ success) into dedicated tools
• Suggests relevant patterns when you start similar tasks

The Overseer

• Runs autonomously on hourly interval
• Identifies crystallization candidates
• Auto-generates tools from high-value patterns
• Prunes stale patterns (30+ days unused)
• Tracks tool performance metrics (ADAS-style evolution)
• Reports actions taken

Native OpenClaw Integration

• AgentSkills Format: Proper YAML frontmatter with metadata (emoji, requires, events)
• Browser Automation: CDP-based browser tool integration for authenticated workflows
• Skill Gating: Auto-generates requires.config, requires.bins, requires.env for dependencies
• Hook System: Full support for OpenClaw hook events (gateway:startup, command:new, etc.)
• ClawdHub Ready: Skills can be published to the ClawdHub registry

Proactive Learning

• Records tool outcomes (success/failure) with context
• Builds patterns from repeated workflows
• Shares learnings via the Foundry Marketplace
• Injects relevant context into agent conversations

Sandbox Validation

• Runs generated code in isolated Node process
• Catches runtime errors before they crash the gateway
• Static security scanning (blocks shell exec, eval, credential access)
• Only deploys code that passes all checks

Restart Resume

• Saves conversation context before gateway restart
• Automatically resumes after restart via managed hook
• No lost work when self-modifying

    "entries": {
      "foundry": { "enabled": true }
    }
  }
}

Option C: GitHub Source

Add to ~/.openclaw/openclaw.json:

{
  "plugins": {
    "entries": {
      "foundry": {
        "enabled": true,
        "source": "github:lekt9/openclaw-foundry"
      }
    }
  }
}

Option D: Nix (Reproducible)

nix run github:lekt9/openclaw-foundry

Option E: Manual Clone

git clone https://github.com/lekt9/openclaw-foundry ~/.openclaw/extensions/foundry

How It Works

1. Observe Phase

Foundry watches every workflow:
  - Goal: What the user is trying to do
  - Tools: Sequence of tool calls
  - Outcome: Success, failure, or partial
  - Duration: How long it took

2. Research Phase

User: "Add a tool that fetches weather data"

Foundry:
  1. Searches docs.openclaw.ai for tool registration patterns
  2. Finds examples of API-calling tools
  3. Identifies best practices for error handling

3. Learn Phase

Foundry:
  1. Records workflow patterns
  2. Tracks success rates per pattern
  3. Identifies crystallization candidates
  4. Builds knowledge base of what works

4. Write Phase

Foundry:
  1. Generates extension code following patterns
  2. Includes proper TypeScript types
  3. Adds error handling and logging
  4. Validates in isolated sandbox

5. Deploy Phase

Foundry:
  1. Writes to ~/.openclaw/extensions/
  2. Creates openclaw.plugin.json
  3. Triggers gateway restart
  4. Resumes conversation automatically

Skill Generation

Foundry generates skills in the AgentSkills format with proper YAML frontmatter:

---
name: my-api-skill
description: Integrates with My API service
metadata: {"openclaw":{"emoji":"🔌","requires":{"env":["MY_API_KEY"]}}}
---

# My API Skill

## Authentication
This skill requires the `MY_API_KEY` environment variable.

## Endpoints
- `GET /users` - List all users
- `POST /users` - Create a new user

Browser Skills

Browser automation skills automatically gate on browser.enabled:

---
name: my-browser-skill
description: Automates login workflow
metadata: {"openclaw":{"emoji":"🌐","requires":{"config":["browser.enabled"]}}}
---

# My Browser Skill

## Workflow
1. Open login page
2. Fill credentials
3. Submit form
4. Verify success

Standalone Hooks

Hooks follow the HOOK.md + handler.ts pattern:

my-hook/
├── HOOK.md          # Frontmatter + documentation
└── handler.ts       # Event handler code

Sandbox Security

Generated code is validated before deployment:

Blocked Patterns (Instant Reject)

• child_process / exec / spawn — Shell execution
• eval() / new Function() — Dynamic code execution
• ~/.ssh/ / id_rsa — SSH key access
• ~/.aws/ / aws_secret — Cloud credentials
• Exfiltration domains (ngrok, webhook.site, etc.)

Flagged Patterns (Warning)

• process.env — Environment variable access
• fs.readFile / fs.writeFile — Filesystem access
• Base64 encoding — Potential obfuscation

Runtime Validation

1. Write extension to temp directory
2. Spawn isolated Node process with tsx
3. Mock OpenClaw API
4. Try to import and run register()
5. If fails → reject with error message
6. If passes → deploy to real extensions directory

Research Foundations

Foundry's self-improvement mechanisms draw from recent advances in autonomous learning agents:

Self-Improving Code Agents

Paper	Key Insight	Foundry Application
Self-Improving Coding Agent (Robeyns et al., 2025)	Agent systems with coding tools can autonomously edit themselves, achieving 17-53% improvement through "non-gradient learning via LLM reflection and code updates"	foundry_extend_self — the agent modifies its own codebase
From Language Models to Practical Self-Improving Computer Agents (Shinn et al., 2024)	LLM agents can "systematically generate software to augment themselves" starting from minimal capabilities	Self-written tools/hooks that expand Foundry's capabilities
SelfEvolve (Jiang et al., 2023)	Two-step pipeline: knowledge generation + self-reflection debugging using interpreter feedback	LearningEngine records outcomes → patterns → crystallization

Recursive Introspection

Paper	Key Insight	Foundry Application
RISE: Recursive Introspection (Qu et al., 2024)	Iterative fine-tuning teaches models to "alter responses after unsuccessful attempts" via multi-turn MDPs	Workflow tracking learns from outcomes, suggests improvements
HexMachina (Liu et al., 2025)	"Artifact-centric continual learning" — separates discovery from strategy evolution through code refinement	Patterns (knowledge) crystallize into hooks/tools (behavior)

Meta-Agent Search

Paper	Key Insight	Foundry Application
ADAS: Automated Design of Agentic Systems (Hu et al., 2024)	Meta-agent iteratively discovers improved agent designs through archive-based evolution	Overseer tracks tool fitness, evolves patterns

Core Principle

"An agent system, equipped with basic coding tools, can autonomously edit itself, and thereby improve its performance" — Robeyns et al.

Foundry operationalizes this: the system that writes the code IS the code being written.
