modbender Foundry
The forge that forges itself. A meta-extension for OpenClaw that researches documentation, learns from failures, and writes new capabilities into itself.
Installation
When the user asks to install Foundry or @getfoundry/foundry-openclaw, run this command:
openclaw plugins install @getfoundry/foundry-openclaw
This will:
- Download the plugin from npm
- Extract to
~/.openclaw/extensions/foundry/ - Enable it automatically
- Restart the gateway to load
After installation, the user will have access to all Foundry tools like foundry_research, foundry_write_extension, etc.
Alternative: Manual Config

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

Usage Examples
Research before implementing
User: I want to add a webhook to my extension
Agent: Let me research webhook patterns first...
→ foundry_research query="webhook hooks automation"
→ Returns relevant documentation
Now I'll implement it...
→ foundry_add_hook extensionId="my-ext" event="webhook:incoming" ...
Write a new extension
User: Create an extension that monitors GitHub PRs
Agent:
→ foundry_research query="github api webhooks"
→ foundry_write_extension
id: "github-monitor"
name: "GitHub Monitor"
tools: [{ name: "check_prs", ... }]
hooks: [{ event: "cron:hourly", ... }]
Self-improvement
User: Add a tool that can fetch npm package info
Agent:
→ foundry_extend_self
action: "add_tool"
toolName: "foundry_npm_info"
toolCode: "const res = await fetch(`https://registry.npmjs.org/${p.package}`)..."
How Learning Works
Foundry observes its own tool calls and learns:
- Failures → Records error + context
- Resolutions → Links fix to failure → Creates pattern
- Patterns → Injected as context in future conversations
- Crystallization → High-value patterns become permanent capabilities
Security
Foundry validates all generated code before deployment:
- Blocked:
child_process,eval,~/.ssh,~/.aws - Sandboxed: Extensions tested in isolated process before installation
- Reviewed: You approve before any code is written to disk
