What it does

Release is an agent skill from Bloom-Engine/engine. Cut a new Bloom Engine release — bump package.json if requested, commit, tag, push, create GitHub Release, and watch the gated release pipeline

Its SKILL.md is about 1.4k 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 Game Development, covering Game development. It works with npm, GitHub, Rust and TypeScript. The repository describes itself as: Native TypeScript game engine — compiles to Metal, DirectX 12, Vulkan, and OpenGL. The licence is MIT.

When your agent uses it

  • Tasks that involve Game development

Example prompts

  • “/release”

Requirements

  • Pre-approved tools (allowed-tools): Bash, Read, Edit, Write, Glob, Grep

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Sanity checks
  2. Determine the target version
  3. Verify the tag doesn't exist
  4. Survey commits since the last tag
  5. Push the bump commit (if any) + tag
  6. Create the GitHub Release
  7. Watch the pipeline
  8. Report back

What it can do on your machine

Read from SKILL.md and the folder at commit 82fd842. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read
    • Edit
    • Write
    • Glob
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.

    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 1.4k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 670 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

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.

New Bloom Release

Model (important — read before acting)

Bloom is a library, not a CLI. It's consumed by games as "bloom": "file:../../" or (eventually) via npm. The release event therefore is:

  1. The version in package.json is the version to ship.
  2. Tag HEAD (or the commit that bumped the version) with vX.Y.Z.
  3. Push the tag. This fires .github/workflows/release.yml, which gates on the Tests workflow passing for the same SHA and then creates the GitHub Release.
  4. Watch both workflows. Report success or failure.

Unlike Perry, Bloom does not bump the patch version on every commit. The version in package.json is bumped explicitly at release time. /release can do the bump for you if you pass patch / minor / major, or you can bump it in a regular commit first and just run /release to tag HEAD.

Steps

1. Sanity checks
  • git status — must be clean (unless we're about to do a patch/minor/major bump, in which case a dirty package.json alone is acceptable only if you are the one about to edit it).
  • git rev-parse --abbrev-ref HEAD — must be main. If not, STOP and ask.
  • git fetch origin && git log HEAD..origin/main --oneline — must be empty. If origin is ahead, pull first.
2. Determine the target version
  • Read package.json version field.
  • If $ARGUMENTS is patch / minor / major:
    • Compute the new version.
    • Edit package.json.
    • git add package.json && git commit -m "chore(release): vX.Y.Z".
  • Otherwise the current package.json version is the release version. Do not bump.
3. Verify the tag doesn't exist
bash
git rev-parse "vX.Y.Z" 2>/dev/null && echo "tag exists — aborting" && exit 1
git ls-remote --tags origin "vX.Y.Z" | grep -q "vX.Y.Z" && echo "tag exists on origin — aborting" && exit 1

If the tag already exists locally or on origin, STOP. Either the release already shipped or someone started it and didn't finish — don't silently duplicate. Retagging a published version is a cardinal sin.

4. Survey commits since the last tag
bash
last_tag=$(git describe --tags --abbrev=0 2>/dev/null || echo "")
if [ -n "$last_tag" ]; then
  git log "$last_tag"..HEAD --oneline
else
  git log --oneline -20   # first release — no previous tag
fi

Group the subjects mentally by feat: / fix: / perf: / docs: / chore:. These become the "Highlights / Features / Fixes" sections in the release body.

5. Push the bump commit (if any) + tag
bash
# If step 2 created a bump commit:
git push origin main

git tag "vX.Y.Z"
git push origin "vX.Y.Z"

The tag push fires two workflows in parallel:

  • test.yml — full CI matrix (macOS / Linux / Windows builds, shared-crate tests, WASM build)
  • release.yml — its await-tests job polls for the test.yml run on the same SHA and gates the release on it
6. Create the GitHub Release
bash
gh release create "vX.Y.Z" \
  --title "vX.Y.Z" \
  --notes "$(cat <<'EOF'
## Highlights
- ...

## Features
- ...

## Fixes
- ...

## Infrastructure
- ...
EOF
)"

If $ARGUMENTS contained free-text highlights (anything other than the patch/minor/major keywords), seed the "Highlights" section from it.

If you skip the gh release create step, release.yml's github-release job will auto-create a release with --generate-notes once the gate passes. The explicit-body path is preferred when there's narrative worth writing; the auto-notes fallback keeps the release from just not existing if something goes sideways.

Show full SKILL.md (247 more words)Show less
7. Watch the pipeline
bash
gh run watch $(gh run list --workflow="Release" --limit 1 --json databaseId --jq '.[0].databaseId')

Expected timeline:

  • Tests finishes in ~15-25 min (Linux + Windows Jolt cmake build dominates cold runs)
  • Release await-tests unblocks, then github-release creates the release if needed

If Tests failed, await-tests will fail loudly and the release will not be created. Do not re-tag vX.Y.Z — fix on main, bump to vX.Y.(Z+1), and /release that. Retagging a published tag breaks npm/git consumers that already resolved the old SHA.

8. Report back
  • GitHub release URL
  • Whether Tests + Release both went green
  • The new package.json version + tag

Failure modes

  • Dirty worktree (unrelated files): STOP. Commit or stash first — don't sweep random changes into a release commit.
  • Tag already exists: STOP. Investigate before deciding whether to bump further or resume a partial release.
  • Tests failed on the tag SHA: await-tests blocks release creation. Fix on main, bump patch, /release again. The stale tag is harmless noise — no GH release body, no assets.
  • Not on main / origin ahead: STOP. Releases come off main. Pull and reconcile before tagging.

What NOT to do

  • Do not bump the version and add unrelated changes in the same commit. Keep the bump commit mechanical: chore(release): vX.Y.Z, one file.
  • Do not force-push tags.
  • Do not use git add -A anywhere in this skill — scoped git add package.json only.
  • Do not try to amend a release commit after the tag is pushed. If the body is wrong, gh release edit vX.Y.Z --notes "...".
  • Do not skip the test gate. Manual workflow_dispatch of release.yml exists for emergencies only.

Questions about Release

What does Release do?

Cut a new Bloom Engine release — bump package.json if requested, commit, tag, push, create GitHub Release, and watch the gated release pipeline. Release is an agent skill from Bloom-Engine/engine.

When should I use Release?

Release fits situations like: tasks that involve Game development.

How do I install Release in Claude Code?

Run `npx skills add Bloom-Engine/engine --skill release -a claude-code`. Or copy the skill folder (.claude/skills/release in Bloom-Engine/engine) into .claude/skills/release in your project. Claude Code loads it when a task matches its description.

How do I install Release in Codex?

Run `npx skills add Bloom-Engine/engine --skill release -a codex`. Or copy the skill folder (.claude/skills/release in Bloom-Engine/engine) into .agents/skills/release in your project. Codex loads it when a task matches its description.

Can I use Release in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Bloom-Engine/engine --skill release -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/release, .gemini/skills/release, .github/skills/release and .opencode/skills/release in your project.

What does Release need to run?

Going by SKILL.md and its folder, Release needs the command-line tools its instructions call (git and gh). Its frontmatter pre-approves these tools: Bash, Read, Edit, Write, Glob, Grep.

Does Release access the network?

SKILL.md contains no URLs. Its commands use git and gh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Release safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Release use?

Release is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Release use?

About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Release?

Skills that share tags, products or a category with Release: Release TS SDK (aptos-labs/aptos-ts-sdk, 116 stars), Release (cyanfish-x/tellux, 207 stars), Logseq Plugin SDK (logseq/logseq, 45k stars) and Verdaccio Pull Request Workflow (verdaccio/verdaccio, 18k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Release?

Bloom-Engine (a GitHub organization) maintains it in Bloom-Engine/engine, which has 134 GitHub stars. The repository was last updated on September 11, 2026.
