What it does

Vellum PR Readiness is an agent skill from vellum-ai/vellum-assistant. Prepare Vellum Assistant branches for review by checking git hygiene, PR scope, tests, docs, migrations, Linear linking, and companion repo needs. Use before creating a pull request, splitting work into PRs, or asking whether a branch is ready.

Its SKILL.md is about 530 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 Pull requests. It works with Git. The repository describes itself as: An AI Assistant that’s easy to setup, does your work 24/7, knows your preferences and gets better over time. The licence is MIT.

When your agent uses it

  • Tasks that involve Pull requests

Example prompts

  • “/vellum-pr-readiness”

Workflow steps

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

  1. Inspect git status and identify unrelated changes, generated artifacts, deleted files, and untracked files.
  2. Inspect staged and unstaged diffs before recommending a commit or PR.
  3. Check for secrets
  4. Check scope
  5. Check required follow-ups
  6. Check Linear conventions
  7. Check verification

What it can do on your machine

Read from SKILL.md and the folder at commit 33cc983. 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

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Vellum PR Readiness loads about 533 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 242 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~533

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.

  • NoteMentions a .env fileSKILL.md:17
    - Do not commit `.env`, credentials, tokens, private keys, or local workspace data.

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.

Vellum PR Readiness

Goal

Confirm the branch is reviewable, scoped, and verified before opening a PR. Prefer surfacing blockers over polishing summaries.

Checklist

  1. Inspect git status and identify unrelated changes, generated artifacts, deleted files, and untracked files.
  2. Inspect staged and unstaged diffs before recommending a commit or PR.
  3. Check for secrets:
    • Do not commit .env, credentials, tokens, private keys, or local workspace data.
    • .env.example is allowed only for placeholder values.
  4. Check scope:
    • If the branch is too large, suggest splitting it into smaller, reviewable PR branches.
    • Separate unrelated UI, backend, migration, and infra changes when practical.
  5. Check required follow-ups:
    • Migration needed for persisted data or workspace format changes.
    • Docs needed for significant architecture, service, or data-flow changes.
    • Companion vellum-assistant-platform PR needed for platform-affecting contracts or new feature flags.
  6. Check Linear conventions:
    • Branch, commit body, and PR body should include the Linear issue ID when one exists.
    • Use Closes JARVIS-123 for single final PRs.
    • Use Part of JARVIS-123 for intermediate PRs in multi-PR plans.
  7. Check verification:
    • Focused tests ran for changed behavior.
    • Typecheck ran when exported contracts or cross-package types changed.
    • Any skipped tests are explicitly called out.

PR Body Template

Use this compact structure unless the user asks for another format:

markdown
## Summary
- ...

## Test Plan
- ...

## Risk
- ...

Mention migrations, feature flags, rollout state, and companion PRs when relevant.

Human Attention Comments

For non-routine changes, leave a PR comment calling out review focus and risk level. Skip this for routine low-risk changes.
