What it does

Release is an agent skill from sean-brydon/berthd. Cut a Shipyard release (vX.Y.Z) - version bump, changelog, tag, and checking the published app and update feed. Use when asked to release, retag, or check a release.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Changelog and release notes. The repository describes itself as: Run coding agents on your dev boxes: worktrees, terminals, orchestration, kits and automations, with a desktop app. The licence is MIT.

When your agent uses it

  • Asked to release
  • Check a release

Example prompts

  • “/release”

Requirements

  • Docker

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. checks: calls ci.yml: Go with -race and a real Chromium, shellcheck, the app's checks, tests and build, and the docs build. A tag skips…
  2. tmux: static tmux for Linux boxes (Docker, on a hosted runner). It runs in parallel with checks.
  3. release: builds berth/berthd archives for darwin and linux, amd64 and arm64, and makes a draft release.
  4. macos: the universal app, signed, notarized and stapled. It uploads the dmg and updater archive, then latest.json last, then publishes the…

What it can do on your machine

Read from SKILL.md and the folder at commit 0317b3b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • gh
    • cargo
    • curl
    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Release loads about 699 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 223 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~699

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Releasing

The tag is the release. Pushing vX.Y.Z runs .github/workflows/release.yml:

  1. checks: calls ci.yml: Go with -race and a real Chromium, shellcheck, the app's checks, tests and build, and the docs build. A tag skips the e2e suite. Nothing is built if any check fails.
  2. tmux: static tmux for Linux boxes (Docker, on a hosted runner). It runs in parallel with checks.
  3. release: builds berth/berthd archives for darwin and linux, amd64 and arm64, and makes a draft release.
  4. macos: the universal app, signed, notarized and stapled. It uploads the dmg and updater archive, then latest.json last, then publishes the release as Latest. This takes about 30 minutes.

Only people the "Release tags" ruleset lets through can push v* tags. An agent usually can't push a tag; prepare everything and give the user the command.

Prepare

sh
V=0.3.11   # no leading v
sed -i '' "s/\"version\": \"OLD\"/\"version\": \"$V\"/" app/package.json app/src-tauri/tauri.conf.json
sed -i '' "s/^version = \"OLD\"/version = \"$V\"/" app/src-tauri/Cargo.toml
(cd app/src-tauri && cargo update -p berth --offline)   # Cargo.lock
sed -i '' "s/^## Unreleased$/## v$V/" docs/changelog.mdx
git commit -am "release: v$V"

If the release has an entry in app/src/lib/whats-new-releases.ts, its version must match.

Check CI is green on the commit (gh pr checks or gh run list). Then the user runs:

sh
git push origin main && git tag -a "v$V" -m "Shipyard v$V" && git push origin "v$V"

Retag after a failure

Nothing is published until the macos job finishes, so a failed run leaves at most a draft.

sh
gh run cancel <run-id>                 # if still running
gh release delete "v$V" --yes || true     # only if a draft exists
git push origin :refs/tags/v$V && git tag -f -a "v$V" -m "Shipyard v$V" <sha> && git push origin "v$V"

Check it's live

sh
gh run watch <run-id> --exit-status
gh release list --limit 2                                   # v$V marked Latest
curl -fsSL https://github.com/cosscom/shipyard/releases/latest/download/latest.json | jq .version
gh release download "v$V" -p 'Berth-macos-universal.dmg' -D /tmp/rel   # asset names keep "Berth"
hdiutil attach -nobrowse -mountpoint /tmp/rel/mnt /tmp/rel/Berth-macos-universal.dmg
spctl -a -vv /tmp/rel/mnt/*.app     # expect: source=Notarized Developer ID
hdiutil detach /tmp/rel/mnt

Boxes keep their old berthd until upgraded (berth upgrade BOX, or "Update all" in the app's status bar). Say so in the release notes when a feature needs the new daemon.
