Use pnpm for node and uv for python to install and update dependencies.
Run pnpm run format, pnpm run lint and pnpm run typecheck before committing changes.
When modifying the SDK packages, ensure equivalent changes are applied to both JS as well as sync and async Python implementations.
Never edit the API, envd, or volume-content specs in spec/ by hand; they are synced with Copybara from e2b-dev/infra and e2b-dev/belt at the commits pinned in spec/infra-ref and spec/belt-ref (see copy.bara.sky and spec/README.md). To update the specs, bump the pins and re-run make codegen, which re-fetches them before generating.
Create or update tests covering affected codepaths and run them using pnpm run test.
Generate a changeset when updating packages/cli, packages/js-sdk, packages/python-sdk with pnpm changeset in the repository root.
When creating a pull request, add usage examples for user-facing changes to the PR description.
When opening a new pull request, use the Linear MCP if available to link to related issues, or create a new issue from the PR description.
Keep PR descriptions up-to-date with changes.
Default credentials are stored in .env.local in the repository root or inside ~/.e2b/config.json.
