Summary

• Fixes [Bug]: OpenClaw talks about Homebrew on FreeBSD #68893 by showing the Homebrew recommendation only on supported Homebrew platforms: macOS and Linux.
• Keeps existing macOS/Linux behavior when a brew-backed skill is selected and brew is missing.
• Adds regression coverage so FreeBSD does not receive the Homebrew recommendation, and aligns the positive Homebrew test with the same platform predicate.

Credit

This carries forward the useful work from #68894, #68910, #68941, #68943, #69002, and #69545. Thanks @Sanjays2402, @Eruditi, @JustInCache, @nnish16, and @Mlightsnow for the source PRs and test ideas.

Validation

• pnpm -s vitest run src/commands/onboard-skills.test.ts
• pnpm check:changed

Notes

Current main at 6aa8337 still uses process.platform !== "win32" for needsBrewPrompt, so unsupported non-Windows platforms remain prompt-eligible until this lands.
