Pastable superpowers for your codebases.
Build context files (agents, rules, MCP configs, etc.) for AI coding tools. Compose them in a browser workspace, then generate a single install-in-one-click script that recreates the files inside any repo.
We’re basically your context manager 🗂️ — helping you create, modify, and improve your coding context for AI coding agents through simple files. Drop in rules, agents, or MCP configs and watch your agents level up ⚡.
- 🖥️ Visual workspace: File tree + Monaco editor + quick actions, persisted in
localStorage
. - 🔄 Instant sharing: Every change turns into a fresh one-click install script (short hash included).
- 🤖 Plug-and-play add-ons:
- Agents from
app/actions/agents/*.md
- Rules from
app/actions/rules/*.md
- MCPs from
app/actions/mcps.json
→ toggled into.mcp.json

This project uses uv for package management.
- Install
uv pip install -r requirements.txt
- Run the dev server
uvicorn app.main:app --reload
- Open the site → Use Quick start buttons to add Agents / Rules / MCPs.
- Workspace → Files appear in the left tree; edit in the center editor.
- One-click install → Top-right shows a shell command, for example:
sh -c "$(curl -fsSL http://localhost:8000/api/install/<HASH>.sh)"
It creates folders, writes files, and lists any required environment variables it detected.
🔐 Security tip: As with any
curl | sh
, inspect the script first:curl -fsSL http://localhost:8000/api/install/<HASH>.sh

Agent: drop
my-agent.md
intoapp/actions/agents/
The UI label is derived from the filename (kebab → Title Case). -
Rule: drop
my-rule.md
intoapp/actions/rules/
-
MCP preset: edit
app/actions/mcps.json
The installer toggles entries into.mcp.json
and surfaces any${ENV_VAR}
strings it finds.
