Prerequisites

Pimate is a hybrid plugin that runs a local Pi Coding Agent process in the background.

1. Install Node.js 18+ (if not already installed)
2. Install Pi globally:

   npm install -g --ignore-scripts @earendil-works/pi-coding-agent
   

3. Configure an API key (choose one):

   # Claude (subscription or API key)
   export ANTHROPIC_API_KEY=sk-ant-...
   
   # Or use Pi's built-in login flow:
   pi
   /login  # Then select provider
   

4. Verify Pi works:

   pi --version

How It Works

Obsidian Plugin (TypeScript)
  ├── main.ts              — Plugin entry, commands, views
  ├── PiAgentView.ts       — Chat UI, streaming, events
  ├── PiAgentClient.ts     — Pi RPC client (JSONL over stdio)
  ├── PiAgentSettings.ts   — Settings and OAuth flows
  └── styles.css           — Claudian-inspired chat styles

Pimate launches Pi as a child process in RPC mode (--mode rpc) and communicates via JSONL messages over stdin/stdout. Pi's full toolset (read, write, edit, bash, grep, find, ls) is available to the model through this interface.

Keyboard Shortcuts

Security & Permissions

Pimate uses a few sensitive capabilities so it can act as a local coding/writing agent:

• Direct file-system access (fs) — used to read local Pi configuration/session files, inspect skill folders, and read files you attach as context. Pimate is desktop-only and runs locally.

• Command execution (child_process) — used to spawn the pi CLI in RPC mode and to run explicit skill-management commands from the settings page. The Pi agent may use shell tools such as bash, grep, and find when you ask it to work on files.

• Vault enumeration — used to find Markdown files/folders for context pickers, history/session helpers, and folder attachment features.

• Clipboard access — used only for explicit copy actions, such as copying generated commands, diffs, authentication codes, or modal content.

Because Pimate embeds a local agent, review commands and edits before approving them. Your API keys and vault content are handled locally by the plugin/Pi CLI except for requests you intentionally send to your selected AI provider.
