verctl

It reads .changeset/*.md, bumps declared version files, writes changelogs, and opens or updates one prepare-release PR.

It is not @changesets/cli, not Knope, and not a forkctl verb.

mise run ver status
mise run ver check
mise run ver prepare
mise run ver prepare --pr
mise run ver publish

Setup

min_version = "2026.7.7"

[settings]
experimental = true
lockfile = true

[task_config]
includes = [
  "git::https://github.com/victor-software-house/verctl.git//tasks/ver?ref=<tag>",
]

mise run ver status
mise run ver check
mise run ver publish --dry-run

Until a GitHub Release exists, build from this repo:

cargo run -- status

Output

Every command returns one typed report. Pretty, --color never, and --format json render the same data. JSON and human errors share that report contract; JSON errors use stdout, while human errors use stderr. --quiet suppresses only successful human output.

Fragments

Same file shape as Changesets. YAML fence. Quoted or unquoted keys.

---
forkctl: patch
"@scope/pkg": patch
---

Restore mise.toml when later patches unapply.

Allowed bumps: major, minor, patch, none.

An optional verctl:group key, added, changed, or fixed, files the entry under that heading. A section where no fragment names a group stays a flat list; once one does, the section gets ### Added, ### Changed, and ### Fixed headings, and an ungrouped fragment goes under ### Changed.

A new package starts at 0.0.0, and its first fragment is a patch, so its first release is 0.0.1. Moving to 0.1.0 or 1.0.0 is a separate operator decision. prepare and check refuse a minor or major fragment on a package at 0.0.0, including its pre-releases and builds; to open at 0.1.0 on purpose, set first_minor: true on the package in .ctl/ver.yaml.

Changelog

Rendered with minijinja 2.x from these defaults (override either path):

• templates/changelog.jinja
• templates/dependency-changelog.jinja

Default release line:

PR                - Summary ([#12](https://github.com/org/repo/pull/12)).
Outside + PR      - Summary ([#12](https://github.com/org/repo/pull/12) by [@ext](https://github.com/ext)).
Commit only       - Summary ([`96fb0bc`](https://github.com/org/repo/commit/96fb0bc)).
No link           - Summary.

An entry ends with a single period: a summary that already ends with one loses it before the reference, so Summary. with a pull request renders - Summary ([#12](…))..

No extra thanks line. If a PR exists, the SHA is omitted.

The pull request is the trailing (#N) in the subject of the commit that added the fragment, which GitHub's squash merge writes; without one the entry links that commit. Release notes credit no maintainer: list maintainers and the Apps that open pull requests in changelog.internal_authors. With a token, a byline needs a login outside that list, a person rather than a bot, and a pull request from a fork.

Version files

verctl prepare applies fragment bumps through drivers. Local writes are the default. prepare --pr is the Version PR (Action happy path; the token is GITHUB_TOKEN, not the gh account). prepare --dry-run / --preview prints the plan and writes nothing. prepare --pr --preview also shows consumed fragments and open vs update. Cargo and npm are stock drivers, not a separate code path.

A repo's declarations live in one file, .ctl/ver.yaml. .ctl/ is the directory every ctl CLI shares, so a repo root gains one entry however many of them it uses.

drivers:
  cargo:
    format: toml
    keys: [workspace.package.version, package.version]
    # after is optional. If omitted, verctl looks at lockfiles /
    # packageManager (bun, pnpm, yarn, npm) and Cargo.lock.

  npm:
    format: json
    keys: [version]
    # after: mise run install           # overrides detection

packages:
  - name: verctl
    path: Cargo.toml
    # driver: cargo   # inferred from the file name

  - name: other
    path: VERSION
    read: ver-read-version              # mise run ver-read-version
    write: [printenv, VERCTL_VERSION]

A string is a mise task. A list is execvp (no shell). Stdin is the file. Write drivers also get VERCTL_VERSION. Stdout is the version (read) or the new file (write). after is printed, not run.

0.x rejects a major fragment.

Runners

Which machines run the work is configuration. A machine is declared once under runners; the jobs that run on it name it.

# One machine. `labels` is how GitHub finds it — every label at once, so this
# is a single machine carrying three labels, not three machines.
runners:
  big:
    labels: [self-hosted, linux, x64]

# One validation job per entry. Naming two machines gives two checks,
# `verify (big)` and `verify (ns)`. Omit `ci` for one `verify` on ubuntu-latest.
ci:
  verify:
    runners: [big]

# One build target per entry: the name is the job, the tarball, and the
# platform. One tarball is one machine, so `runner` is not a list.
assets:
  darwin-arm64: {}
  linux-x64:
    runner: big

Two sections take runners and no others, because of what config is for here:

verctl decides how many jobs there are. Your workflow file decides where a fixed job runs.

A static YAML file cannot declare N jobs without knowing N, and only the repo knows N. That fan-out is what ci and assets buy; the machine rides along on it. Every other job verctl ships — plan, crate, pin, prepare — is always exactly one job, so nothing decides its count and nothing needs to configure it. Its runs-on is one literal in a workflow you own and already copied from examples/:

  plan:
    runs-on: [self-hosted, linux, x64]   # yours to edit; no declaration needed

So a repo with no hosted runners at all is already served: edit those literals and declare ci / assets. plan could not read its machine from config anyway — runs-on resolves before the job exists, and plan is the job that reads the declarations.

Names sort alphabetically, not in file order, so a verify job written above an audit job still plans audit first. Checks are independent, so the order is display only.

Only labels reaches GitHub. A runner name is a name in the file: it resolves against runners or fails there, listing what is declared, so a label can never pass itself off as a machine and verctl never invents a label. A label GitHub does not know queues the way any wrong label queues — verctl cannot tell which machines carry which labels, so it passes them through.

Built-in target records, so a public repo needs no config to stay on free hosted minutes:

Each field is a default the repo overrides one at a time: naming a runner moves the machine and leaves the platform alone. A name outside that set describes a platform verctl knows nothing about, so it must describe all of it — runner, os, arch, and triple are all required, and a partial record is an error rather than a build against an empty target triple. os: darwin renders as macos in the filename; that is the only rename. triple stays its own field because the machine and what it builds need not match: an x64 linux runner can build aarch64-unknown-linux-gnu.

ci is exactly as trusted as .github/workflows/ci.yml: for a pull_request event both come from the pull request's own tree, so a fork PR that can declare a label could equally have written that label into the workflow file. Neither is a reason to expose a self-hosted runner group to a public repository — keep allows_public_repositories=false there and keep fork-PR approval on, and read declared labels as untrusted input in a repo where that is not true.

verctl ci and verctl assets print what resolved, so a default is visible output rather than an assumption. Both also write a matrix for $GITHUB_OUTPUT: GitHub needs runs-on before a job exists, so a small plan job emits the labels and the real jobs consume them (examples/workflows/ci.yml).

Actions

These replace changesets/action. They are GitHub Actions, not a GitHub App. The runner already has git and GITHUB_TOKEN. PRs are opened with octocrab. Commits and push are git2 with that token, not the git/gh CLIs. There is no local token setup.

Example consumer workflow: examples/workflows/version-pr.yml.

actions/version-pr takes auto-merge: true to merge the Version PR once the base branch's required checks pass. It needs a ruleset that requires a status check on that branch, and a GitHub App token in token.

Mise owns tools. Publish uses Actions OIDC, not a PAT.

A package with publisher: none is released on GitHub only: publish creates its tag and Release, and assets its tarballs, with no registry upload. Use it for private binaries, such as a Cargo package with publish = false.

Operator documents

Clap remains the command grammar. ctl-core Surface renders the shared version, mounted invocation/no---, and visible command-inventory fragments. Verctl's Jinja templates retain domain prose, and operator_docs byte-compares their renders with skills/verctl/SKILL.md and src/instructions.md.
