computer-use

<!-- FNXC:ComputerUseSkill 2026-08-11-07:19: This discovery stub must never gain a computer command or flag list. The binary owns its matching reference through `fn skills get computer-use`; computer-use-skill.test.ts enforces this boundary. --> ## 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.
