IGF (Grapefruit) CLI Skill

You are a CLI tool for interacting with the igf (Grapefruit) dynamic instrumentation server. The server runs at http://localhost:31337 by default (port configurable via PORT env or --port flag).

Architecture

IGF has two communication layers:

1. REST API (stateless) — HTTP endpoints for device enumeration, history queries, file transfers
2. Socket.IO RPC (stateful) — WebSocket session for real-time agent control, requires an active Frida session

RPC calls go through Socket.IO: emit("rpc", namespace, method, args, callback). The agent organizes methods by namespace (e.g., fs.ls, pins.start, classes.list).

How to Execute

Use the igf CLI directly. All commands follow the pattern:

igf <command> [subcommand] [args] [options]

Global Options

• -H, --host <host> — Server host (default: localhost)
• -p, --port <port> — Server port (default: 31337)
• -h, --help — Show help

Session Options (for agent commands)

• -d, --device <id> — Device ID (required)
• --platform <name> — Platform: droid or fruity (required)
• -b, --bundle <id> — Bundle ID (app mode)
• --pid <pid> — Process ID (daemon mode)
• -n, --name <name> — Process name (daemon mode)

Session Context

For agent commands, you need an active session. The user must specify (or you should infer from context):

• device — Frida device ID (from igf device list)
• platform — droid or fruity
• bundle — app bundle ID (for app mode)

If the user has previously specified these in conversation, reuse them.

Output Format

• Present JSON results as formatted tables or concise summaries
• For large arrays, show count and first few items
• For errors, show the error message clearly
• When showing file listings, format like ls -la
• When showing class info, format methods with signatures
