4 use cases

  • Run a persistent AI agent on a focused job

    Give an agent its own cloud computer and one job, then follow its work from your Mac.

    View prompt
    Using the runta-dev/errand repository, install dependencies with npm ci and start the app with npm run dev, then create an agent with the job <target job>. Expected output: a running agent whose conversation shows tool activity for that job. Verify that the conversation is still present after you close and reopen Errand.

  • Send a screenshot to an agent as a follow-up

    Attach an image to a message so the agent sees it as native image input in the same conversation.

    View prompt
    In the runta-dev/errand app, open the conversation for the agent <agent name> and attach the image <image path> to a follow-up asking <question>. Expected output: the agent's reply refers to content from the image. Verify that the attachment is still shown in the conversation after reopening Errand.

  • Fix a bug in Errand and run its checks before a pull request

    Clone the repo, run the typecheck, lint, test, and build scripts, then submit a fix.

    View prompt
    In the runta-dev/errand repository, reproduce the bug <bug description> using npm ci and npm run dev, then apply a fix. Expected output: a diff where npm run typecheck, npm run lint, npm test, and npm run build all pass. Verify each script exits with success before you write the pull request description.

  • Build a local macOS package and smoke test it

    Produce ad-hoc signed Errand builds in release/ and run the smoke check for testing.

    View prompt
    In the runta-dev/errand repository, run npm ci, then npm run package and npm run smoke. Expected output: artifacts in the release/ directory and a passing smoke run. Verify that the DMG contents and blockmap are present before reporting success.
