#16 Edit AI Agents in PenPage, Run Them Instantly
PenPage connects to the three major AI Coding CLIs — edit agents, rules, plans, and prompts in PenPage's rich editor, AI reads and executes them, and you see the results back in PenPage immediately.
Supported AI tools
- Claude Code (Anthropic) —
CLAUDE.md,.claude/directory - Gemini CLI (Google) —
GEMINI.md - Codex CLI (OpenAI) —
AGENTS.md - Any AI tool that reads/writes
.mdfiles in your project
What can you edit?
Not just agents — everything your AI reads:
| File | What it controls |
|---|---|
CLAUDE.md |
Project instructions & coding standards |
.claude/agents/ |
Custom agent definitions |
.claude/rules/ |
Behavioral rules for AI |
.claude/plans/ |
Implementation plans |
GEMINI.md |
Gemini CLI instructions |
AGENTS.md |
Codex CLI agent config |
Agents, plans, rules, skills, prompts — if it's a .md file in your project, PenPage can edit it.
The workflow
- Edit in PenPage → file updates on disk instantly
- AI reads your latest rules and agents
- AI executes and generates new content
- PenPage syncs — you see the results immediately
No copy-paste. No switching between editors. One loop.
Setup
- Click the link icon on a folder
- Select your project directory
- Done — all
.mdfiles sync both ways automatically
Built-in MCP Server
PenPage also includes a built-in MCP Server (Model Context Protocol) — an open standard for AI tools to access external data. Copy the MCP config from Settings and add it to your AI tool's config file.
In most cases, linking the directory is all you need. MCP is there for advanced scenarios that need finer control.
