Publish CLIs/TUIs to Homebrew via a personal tap. Use when asked to create or manage a Homebrew tap repo, generate or update formulae, compute sha256, test installs, or ship new releases for Go, Rust, Node/TypeScript, Python, or prebuilt binaries.

Homebrew Publish

Overview

Create or update a Homebrew tap and formulae so users can install a project's CLI/TUI with brew install OWNER/tap/<formula>.

Workflow

1) Gather inputs

  • Confirm GitHub owner, tap name, and whether the tap repo already exists.
  • Collect project repo URL, release tag/version, and the source tarball URL or prebuilt asset URL(s).
  • Identify build system and language (Go, Rust, Node/TypeScript, Python, or other).
  • Define binary name and a minimal test do command.
  • Confirm target platforms/architectures and whether bottles are desired.

2) Ensure tap repo exists (skip if already set)

  • Create a tap repo using the short form OWNER/tap when possible.
  • Run:
  • brew tap-new OWNER/homebrew-tap (or homebrew-<tapname>)
  • gh repo create OWNER/homebrew-tap --push --public --source "$(brew --repository OWNER/homebrew-tap)"

3) Create the formula skeleton

  • Prefer stable source tarballs from release tags.
  • Run:
  • brew create <url-to-tarball> --tap OWNER/homebrew-tap --set-name <formula>

4) Implement the formula

  • Edit Formula/<formula>.rb and wire build/install/test.
  • Pick a language template from references:
  • references/formula-go.md
  • references/formula-rust.md
  • references/formula-node.md
  • references/formula-python.md
  • references/formula-prebuilt.md
  • Ensure desc, homepage, url, sha256, and license are correct.

5) Compute sha256

  • Use shasum -a 256 <file> for local files.
  • For remote URLs, run curl -L <url> | shasum -a 256.

6) Test locally

  • Run brew install --build-from-source OWNER/tap/<formula>.
  • Run brew test OWNER/tap/<formula>.
  • Optionally run brew audit --strict --online OWNER/tap/<formula>.

7) Commit and push

  • Commit in the tap repo and push to GitHub.

8) Update for new releases

  • Update url and sha256 (and version if needed).
  • Re-run tests, commit, and push.

Notes

  • Prefer source builds unless a prebuilt binary is required.
  • If bottles are enabled, keep the default workflows created by brew tap-new and follow their publish instructions.

How to use it

Copy the folder

Take instructa/homebrew-publish from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference brew. Without those the skill loads but fails at the first command.
