Version and release c15t packages with Changesets. An agent skill from c15t/c15t.

  • Adding a changeset to a PR
  • SKILL.md covers Adding a changeset, Release channels, What the release scripts do and Verifying locally
  • Calls bun and changeset
  • Deciding bump types for the linked package group

What it does

Releasing is an agent skill from c15t/c15t. Version and release c15t packages with Changesets. Use when adding a changeset to a PR, deciding bump types for the linked package group, publishing canary/RC/stable releases, or debugging release CI failures (publish artifacts check, workspace dependency resolution).

Its SKILL.md is about 750 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 Deployment and Failing and flaky tests. The repository describes itself as: The Developer-First Cookie Banner. The licence is Apache-2.0.

When your agent uses it

  • Adding a changeset to a PR
  • Deciding bump types for the linked package group
  • Publishing canary/RC/stable releases
  • Debugging release CI failures (publish artifacts check

Example prompts

  • “/releasing”

What it can do on your machine

Read from SKILL.md and the folder at commit f2b2318. 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:

    • bun
    • changeset

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

  • Network

    No URLs in SKILL.md.

    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

Releasing loads about 753 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~753

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.

Version and release c15t packages with Changesets. Use when adding a changeset to a PR, deciding bump types for the linked package group, publishing canary/RC/stable releases, or debugging release CI failures (publish artifacts check, workspace dependency resolution).

Releasing c15t Packages

Publishing is automated by .github/workflows/release.yml via Changesets. Your job in a PR is usually just to add the right changeset.

Adding a changeset

bash
bun run changeset

Pick the affected packages and a bump. Rules:

  • Any user-facing change to a published package needs a changeset; internal-only changes (tests, benchmarks, internals/, docs-site-only) do not.
  • These packages are linked and always version together — bumping one bumps all: c15t, @c15t/backend, @c15t/cli, @c15t/dev-tools, @c15t/iab, @c15t/nextjs, @c15t/node-sdk, @c15t/react, @c15t/translations. Choose the bump for the most significant change in the group.
  • @c15t/scripts, @c15t/ui, @c15t/schema, and @c15t/logger version independently. @c15t/vue, @c15t/svelte, and @c15t/solid are currently private and unversioned.
  • Write the changeset summary like a changelog entry (it becomes one): imperative, user-facing, mentions migration steps for breaking changes.

Release channels

BranchChannelHow it publishes
canary (default, PR target)--tag canary snapshotsAutomatically on every merge (version:canary + release:canary)
2.0.0RC pre-releaseRelease workflow versions with bun run version and publishes via release:rc; version:rc/version:rc:exit toggle changeset pre mode manually when needed
mainstableChangesets opens a "Version Packages" PR; merging it publishes

sync-canary.yml keeps canary in sync with main.

What the release scripts do

bun run release = build → check:publish-artifacts → resolve-workspace-deps → changeset publish.

  • scripts/check-publish-artifacts.ts fails if test/snapshot/screenshot/MSW/Rsdoctor files would be packed. Fix by keeping tests in __tests__/ or *.test.*/*.spec.* (rslib excludes those) — don't widen the allowlist casually.
  • scripts/resolve-workspace-deps.ts rewrites workspace:* ranges to real versions before publish. If a new workspace dependency breaks publishing, check it's declared with a workspace: protocol.
  • The core SDK packages (c15t, @c15t/react, @c15t/nextjs, @c15t/backend) also run scripts/verify-package-artifacts.ts via prepack as a final tarball sanity check.

Verifying locally

bash
bun run build:libs
bun run check:publish-artifacts
bun pm pack --dry-run --cwd packages/<pkg>   # inspect what would ship

The tarball should match the package's files array — typically dist/ and dist-types/, plus README.md/CHANGELOG.md and (for docs-bundled packages) AGENTS.md + docs/ where listed. No test, snapshot, or mock files, ever.
