changesets

changesets is a cursor rule for Cursor from louisbrulenaudet/monorepo-template. It costs 0 tokens per session (1,418 once invoked), scanned A, original, Apache-2.0.

A set of rules for writing changesets, which are release notes describing user-visible changes in deployed applications. It also covers when a release note is needed and how to choose its version bump.

In plain words
What is it for?
It helps create release notes for application changes, dependency updates, and changes that need no release note but still require an explicit explanation.
Why use it?
It prevents shipped changes from missing release notes or receiving an incorrect version update. It separates information for users and operators from implementation details in commits and pull requests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

changesets scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 15d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Changesets

A changeset is the release note for one user-visible change. Its readers operate or call the deployed apps, in apps/<app>/CHANGELOG.md and in the GitHub Release CD builds from those files; rationale and implementation go in the commit and PR body. Procedure: skill changeset. Config, gate, and pipeline internals: release.mdc.

When

pnpm release:check decides whether a shipped path changed. It also runs in pnpm run ci and PR CI. Every file of an app or of a package it bundles counts, except tests, top-level *.md, turbo.json, Vitest config, and @repo/vitest-config.

Change Changeset
Observable change to a deployed app, including through a bundled @repo/* package patch or minor (see Bump)
Catalog bump of an entry an app lists under dependencies patch naming that app; Dependabot PRs get one committed for them when CHANGESET_BOT_TOKEN is set
Shipped path changed, nothing observable: types, comments, a behavior-identical refactor, devDependency lines in an app package.json --empty with a one-line reason; changeset version deletes it unread
Tests, docs, .github/, agent config, or root tooling only none
  • A fix to a change still pending on main edits that pending changeset: nothing has shipped, so there is nothing new to note.
  • One changeset per logical change: a fix and a feature in one PR are two files. Iterating on your own PR edits the file you added, never a second one for the same change.

Frontmatter

  • Name only apps - the unscoped workspaces under apps/ - each one whose behavior changes. Never an @repo/* package: its entry lands in a packages/*/CHANGELOG.md that no release note reads. release:check enforces this.
  • The fixed group bumps every app to the highest bump anyway; the names only decide which CHANGELOG carries the entry. An app no changeset names gets "No changes in this release.", which the GitHub Release skips.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
