computer-use

When to engage

Use this skill for desktop GUI automation, reading native app state, clicking controls, or filling desktop forms.

Resolve the CLI for this session

Resolve exactly one executable in this order: an explicitly exported FUSION_CLI_BIN, then fn on PATH, then the dev-checkout entry point. Reuse that executable for every command in this session. If resolution fails, report the error and stop; do not fall through to a different binary that could target another build.

Load the full guide before running commands

Using the resolved executable, run fn skills get computer-use before any computer command. It prints the complete guide for the exact binary that will execute work.

Keep this stub thin

This stub deliberately lists no subcommands or flags, so it can never drift from the binary that will actually run your commands.

Older-binary fallback

If that binary does not know skills get, only inspect these read-only capabilities, then ask the user to update Fusion rather than guessing a command surface:

• fn computer capabilities --json
• fn computer permissions --json
• fn computer list-apps --json

macOS is first-class. On other platforms capabilities report supported: false and actions fail with UNSUPPORTED_PLATFORM; stop instead of retrying.
