At a glance

Walks through a Skyvern open-source release bump: update the version, rebuild the Python and TypeScript SDKs with Fern, commit, and open a pull request.

  • Works in 9 steps: Get and validate version → Create feature branch → Update pyproject.toml → …
  • Releasing a new Skyvern OSS version
  • SKILL.md covers What this does, Version argument, Step-by-step process and Important notes, plus 1 more section
  • Calls git, bash and gh; reaches claude.com; needs SKYVERN_API_KEY

What it does

The agent takes a MAJOR.MINOR.PATCH version from the argument or asks you for one, checks the format, shows the current version from `pyproject.toml` and asks you to confirm before creating a `bump-version-` branch and editing the version line. Patch, minor and major bumps are explained with short semver guidance.

It then runs the repository's two Fern scripts to build the Python SDK and the TypeScript SDK, confirms that `skyvern-ts/client/package.json` carries the new version, shows `git status` and a diff summary, and commits everything. After that it offers to run the Python SDK tests with pytest (the TypeScript tests need a manual Chrome setup) and asks again before pushing the branch and opening the pull request. If tests fail, it stops before the push.

When your agent uses it

  • Releasing a new Skyvern OSS version
  • Regenerating both Fern SDKs after changing the package version
  • Opening a version-bump pull request from a clean branch

Example prompts

  • “Bump the version to 1.0.14 and prepare the release PR.”
  • “We need a minor release. Walk me through bumping Skyvern and rebuilding the SDKs.”
  • “Bump the version, but skip the SDK tests and ask me before pushing.”

Requirements

  • A checkout of the Skyvern repository
  • Fern, which the SDK build scripts call
  • Git access to push a branch

Workflow steps

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

  1. Get and validate version
  2. Create feature branch
  3. Update pyproject.toml
  4. Build Python SDK
  5. Build TypeScript SDK
  6. Review changes
  7. Commit changes
  8. Verify SDKs (optional)
  9. Push and create PR

What it can do on your machine

Read from SKILL.md and the folder at commit f5f3f28. 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
    • bash
    • gh
    • pytest

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • claude.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SKYVERN_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skyvern Version Bump loads about 1k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 401 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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:155
    - **Testing**: SDK tests require `.env` with `SKYVERN_API_KEY`

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.

Bump Version Skill

Automate the complete OSS version bump and release workflow for Skyvern.

What this does

  1. Validates and updates version in pyproject.toml
  2. Builds Python SDK with Fern
  3. Builds TypeScript SDK with Fern
  4. Creates commit with all changes
  5. Optionally runs SDK tests
  6. Pushes branch and creates PR

Version argument

The version can be provided as an argument or you'll be prompted:

  • If $ARGUMENTS is provided, use it as the new version
  • If not provided, ask user for the new version number
  • Validate it follows semver format: MAJOR.MINOR.PATCH (e.g., 1.0.14, 1.1.0, 2.0.0)

Semver guidance:

  • PATCH: Bug fixes, backwards compatible (e.g., 1.0.13 → 1.0.14)
  • MINOR: New features, backwards compatible (e.g., 1.0.13 → 1.1.0)
  • MAJOR: Breaking changes (e.g., 1.0.13 → 2.0.0)

Step-by-step process

1. Get and validate version
  • Read current version from pyproject.toml line 3
  • Determine new version from $ARGUMENTS or prompt user
  • Validate semver format using regex: ^\d+\.\d+\.\d+$
  • Confirm with user: "Bumping version from {current} to {new}. Continue?"
2. Create feature branch
bash
git checkout -b bump-version-$ARGUMENTS

Branch naming: bump-version-{version} (e.g., bump-version-1.0.14)

3. Update pyproject.toml

Update line 3 in pyproject.toml:

toml
version = "{new_version}"

Use the Edit tool to make this single-line change.

4. Build Python SDK
bash
bash scripts/fern_build_python_sdk.sh
  • Wait for completion
  • Check output for errors
  • Fern reads version from pyproject.toml
5. Build TypeScript SDK
bash
bash scripts/fern_build_ts_sdk.sh
  • Wait for completion
  • Check output for errors
  • Verify skyvern-ts/client/package.json version matches new version
6. Review changes
bash
git status
git diff --stat

Show user:

  • Number of files changed
  • Which files were modified
  • Summary of changes
7. Commit changes
bash
git add .
git commit -m "Bump version to {version}

- Update version in pyproject.toml
- Regenerate Python SDK with Fern
- Regenerate TypeScript SDK with Fern

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"
Show full SKILL.md (164 more words)Show less
8. Verify SDKs (optional)

Ask user: "Would you like to run SDK tests to verify nothing broke?"

If yes:

  • Python SDK tests: pytest tests/sdk/python_sdk/
  • Note that TypeScript tests require manual Chrome setup (see tests/sdk/README.md)
  • Display test results
  • If tests fail, STOP and report errors - do not proceed to push

If no:

  • Skip to push step
9. Push and create PR

Ask user: "Ready to push and create PR?"

If yes:

bash
git push -u origin bump-version-{version}

gh pr create --title "Bump version to {version}" --body "## Summary
Bump Skyvern OSS version to {version}

## Changes
- Updated version in \`pyproject.toml\`
- Regenerated Python SDK with Fern
- Regenerated TypeScript SDK with Fern

## Deployment
After merge, GitHub will automatically:
- Deploy Python package to PyPI (version change in \`pyproject.toml\`)
- Deploy TypeScript package to NPM (version change in \`package.json\`)

## Testing
- [ ] Python SDK tests passed locally
- [ ] TypeScript SDK tests passed locally (if applicable)

Important notes

  • Single PR: All changes (version bump, SDK generation, commit) happen in one PR
  • Fern sync: Fern reads version from pyproject.toml and syncs to package.json
  • Testing: SDK tests require .env with SKYVERN_API_KEY
  • Deployment: Automatic on PR merge via GitHub Actions
  • No force push: Never use --force when pushing

Error handling

If any step fails:

  1. Display the error message clearly
  2. Explain what went wrong
  3. Ask user how to proceed (fix, skip, or abort)
  4. Do not continue to next steps if critical operations fail
