# DRAFT — groundwork for a future Homebrew tap. NOT published or tapped yet.
#
# Filled in for the v0.4.1 release tarball (url/sha256/version below). The one
# remaining step to make it installable: copy this file into a homebrew-tap repo
# (e.g. minghinmatthewlam/homebrew-tap) so users can
# `brew install minghinmatthewlam/tap/computer-use-mcp`. On each new release,
# update url/version and set `sha256` to `shasum -a 256` of the new tarball.
#
# Note on permissions: Homebrew installs an ad-hoc-signed build from source, which
# is fine for local use but means macOS attributes Accessibility / Screen Recording
# grants to the launching host process, and grants may need re-approval on upgrade.
# For a stable signing identity across upgrades, prefer the notarized release
# artifact (see docs/release/permissions.md).

  def caveats
    <<~EOS
      computer-use-mcp needs Accessibility and Screen Recording permission for the
      terminal or app that launches it. Verify with:
        computer-use-mcp doctor
      For a stable signing identity across upgrades, prefer the notarized release
      build over this from-source install.
