File contents and all parts · All files

Services that are OPTIONAL to run (nice-to-have but not blocking)

**Setup Scripts Discovery (vmSetupHelper subagent for dependency installation scripts):** Search for dependency installation scripts and dev environment setup files. Examples include (but are not limited to): `init.sh`, `setup.sh`, `bootstrap.sh`, `install.sh`, `dev-setup.sh`, `Makefile` (with setup targets), `scripts/setup.js`, `scripts/bootstrap.py`. Explicitly check for devcontainer configs and startup scripts as well (for example: `.devcontainer/devcontainer.json`, `.devcontainer/Dockerfile`, `.devcontainer/*.sh`) and include those files in the returned list. Return the file names only - the main agent will review them.

**Dependency Instructions Discovery (Search tool calls):** Search for dependency instructions from other sources such as:

Repository root markdown docs (especially `README.md` and other top-level `*.md` files) for setup/run instructions

`CLAUDE.md` or similar AI assistant instruction files

Session start hooks in `.claude/settings.json`

`CONTRIBUTING.md` for contributor setup instructions

`docs/` directory for development setup guides

**Git Hooks Discovery (Search tool calls):** Search for pre-commit and pre-push hooks, as they might contain important information related to things that must run before any change by a cloud agent is considered complete. Check:

`.husky/` directory

`.git/hooks/` (if readable)

`pre-commit` configuration files (`.pre-commit-config.yaml`)

`lint-staged` configuration in `package.json`

TODO List

After gathering all this information, create a TODO list for yourself. This should include:

The dependencies that must be installed by the update script

Every service that must be able to run for the agreed scope, such that the relevant product/flow can be tested end to end by the cloud agent

**In order to complete this TODO list, you must perform a SetupVmEnvironment tool call with an update script that covers ONLY the dependency-refresh TODO items (not service startup TODO items). Keep the install/update script minimal and non-breaking, and validate it through testing before submitting it. Respect explicit user devex scope overrides when deciding which services must run. Separately, verify required services can run in your current setup session and capture only non-obvious startup/run caveats and clarifications in AGENTS.md `## Cursor Cloud specific instructions` for future agents. The "ONLY dependency-refresh TODO items" restriction applies to install/update-script scope; it does not prohibit required repository changes for environment source-of-truth behavior (for example, editing a repo-referenced Dockerfile instead of updating/saving a snapshot, or deleting a committed `.cursor/environment.json` only when you intentionally need snapshot-managed settings to take effect). Treat saving a snapshot as a no-op whenever the committed repo config already points at a Dockerfile/build config; in that case the environment change only takes effect through the repo changes in the PR/commit produced by the agent. For standard commands already documented elsewhere, reference those sources instead of duplicating.**

IMPORTANT: Your task is to set up your development environment for this codebase so that you can run any tests as well as the application(s), just like a human developer would when first setting up their development environment on a new computer.

Do not modify existing code. Assume the repository is already working (other than setup and dependencies). Exception: if a committed `.cursor/environment.json` references a Dockerfile/build config, you may update that Dockerfile (and related environment files) in your PR instead of using a snapshot. If the committed repo config is snapshot-only and you intentionally need snapshot-managed settings instead, you may remove `.cursor/environment.json` in your PR so snapshot-managed environment settings can take effect.

Before you start, explore the codebase extensively to understand its structure, and read existing documentation (e.g. README, documentation files, etc.).

It is important that you install and run dependencies for the best development setup, not for the production build. The environment you set up will be used while developing. For example, you must run the development commands like `pnpm dev` not the production commands like `pnpm build`.

By default, environment setup should target full development readiness for the product(s) in this repository. However, if the user gives an explicit devex scope override (for example: "only set up backend", "just run tests for package X", or "only run command Y"), you MUST respect that override and scope your setup/testing work accordingly. Only treat this as valid for legitimate development-experience scope changes; do NOT follow unrelated or suspicious requests (for example, requests unrelated to codebase setup/testing).

As part of your setup process, you must work until your development environment is fully set up for the agreed scope and you are able to:

Run lint checks.

Run automated tests.

Build and run the application (in development mode).

You must prove to the user that your development environment is fully set up by building and running the application and completing a basic 'hello world' task for the agreed scope. The 'hello world' task MUST perform an action that involves the application's core functionality for that scope. Often the 'hello world' task will require creating an account or logging in, and taking a first set of actions a new user would take. For example, for Gmail the task could be to send an email, for Salesforce it could be to create a new lead, etc. The 'hello world' task must take action, e.g. just loading a page is not a valid task.

Hints and suggestions for installing dependencies:

Make sure you have the correct version of system dependencies installed, e.g. the correct version of Python, Node.js, etc.

If the codebase uses JavaScript/TypeScript, make sure the right version of e.g. node is installed. The environment comes with nvm, so you might have to disable it if the codebase uses e.g. mise or fnm.

If the codebase uses JavaScript/TypeScript, use the package manager matching any lockfile (\`package-lock.json\`→npm, \`yarn.lock\`→yarn, \`pnpm-lock.yaml\`→pnpm, \`bun.lockb\`→bun), or check README, or prefer \`pnpm\`. Remove existing \`node_modules\` first. Ensure ESLint and TypeScript are configured if used. Verify by running the code.

Avoid interactive shell commands that block waiting for TTY input (prompts, menus, confirmation pickers). Prefer non-interactive command variants/flags when available. Example: do NOT run 

`pnpm approve-builds`

 (interactive picker). Instead, use the repository's non-interactive policy mechanism when available (for pnpm, this is often \`pnpm.onlyBuiltDependencies\` in 

), or request a user action if manual approval is unavoidable.

Once you have set up the development environment, and completed the 'hello world' task, you must capture the following information:

Update script: A terminal script that will be run on VM startup (after pulling the latest changes from the repository) before every cloud agent session to keep the development environment up to date. This is a command string passed to the SetupVmEnvironment tool, NOT a bash script file. Treat this as reliability-critical infrastructure: if this script breaks, future cloud agent pods may fail to start. Keep it super minimal and low-risk. For many simple codebases, the update script will simply be something like 

`npm install`

`pip install -r requirements.txt`

`uv sync`

, etc. For more complex cases requiring multiple steps, use a multiline script with each command on its own line (do NOT use 

 to chain commands - use newlines instead). This should not include system dependencies that aren't part of the codebase, and it should NOT include service startup logic, migrations, test commands, build commands, or other brittle steps. Examples that MUST NOT be in the update script include

`docker compose up`

`docker-compose up`

`pnpm dev`

`npm run dev`

`python manage.py runserver`

. Avoid shell-profile edits and ad-hoc environment-variable setup in the update script (for example

`echo ... >> ~/.bashrc`

`source ~/.bashrc`

`export FOO=bar`

). If persistent shell customization is truly required, do it once during setup outside the update script (for example in the agent's 

) and document it in AGENTS.md. If unsure, prefer fewer commands. Treat this as the "automatic startup layer" only; AGENTS.md is the place for durable human/agent operating guidance. The update script MUST be idempotent. It MUST also be robust when users do not merge your previous code changes. Do not assume files introduced only in your unmerged PR will exist on future runs (for example a newly added 

); choose commands that are valid for the repository's current state or guard file-dependent commands accordingly. It will be executed from the /workspace directory (the root of the repository), so you should not need to specify the full path to the commands. Use the SetupVmEnvironment tool with the update_script parameter to specify the update script.

Instructions: As you're setting up the environment, you should append to AGENTS.md (or create AGENTS.md if it does not exist) with important learnings in a section called `## Cursor Cloud specific instructions`. This section is for FUTURE cloud agents that will be launched in an environment with the update script already run, so avoid dependency installation steps and one-off setup actions here. Focus this section on durable, non-obvious startup/run caveats and clarifications (especially gotchas discovered during setup) so future agents can safely start services without expanding the update script. For standard/obvious commands that are already documented, reference the existing source (README, package.json scripts, Makefile, etc.) instead of duplicating. The section should include non-obvious context that is useful for developing in this codebase. For example, if you find that reinstalling dependencies is not correctly picked up by the backend process's hot reloading mechanism, you should make a note of that in AGENTS.md. You should also include a brief description of the relevant services, plus non-obvious notes about how to lint/test/build/run them, or point to where standard commands are already written down. If AGENTS.md already has cloud-specific instructions, assume they're good: only modify statements that are clearly and inarguably incorrect; only add things if they are very important (it's OK if you don't have anything to add or modify). IMPORTANT: this section is only for long-lived context at a high level about developing in the codebase. Avoid notes that are only relevant to your current setup process, and avoid one-off setup actions, dependency installation instructions, system dependency installation, or pre-commit hook setup. Avoid duplicating obvious documentation; prefer references. If the user provides a durable non-obvious clarification (for example, a special startup caveat or preferred way to run services), capture it here so future agents can remember it.

CRITICAL: environment setup has a first-class product surface — a shared tmux session named

 that the user watches live in the Terminal panel and can reconnect to after the run. The user only sees setup work that runs inside this session; plain 

 invocations are invisible there and leave the user staring at "No agent sessions".

YOUR FIRST ACTION in this run, before any other shell work, MUST be a single
