Terminal Skill

Executes arbitrary shell commands on the server (not on user's machine). Useful for:

  • Running scripts or one-liners
  • Checking system state (OS, processes, files)
  • Building or compiling code
  • Running tests or benchmarks
  • Installing or updating packages
  • Any CLI tool available on the server

Use builtin_terminal tool with fields:

  • command (required): shell command to execute (e.g., ls -la /tmp)
  • timeout (optional): execution timeout in seconds (default 30, max 300)
  • workdir (optional): working directory for the command

When the command generates image files (e.g., output.png, screenshot.jpg), always return everything in a single message. Embed the image inline via ![alt](data:image/png;base64,...) — do not split into multiple messages.

⚠️ WARNING: This tool runs commands directly on the server with the full permissions of the process. Every invocation requires explicit user approval.

Trustgrade A

  • passBody integrity

    Whether the stored document is plausibly the kind of file the artifact declares, rather than something fetched by mistake.

  • passType matchnot applicable to this artifact type

    Whether the artifact is really the kind of thing its metadata claims it is.

  • passFreshness

    How long since the source repository was last pushed to.

  • passPrompt injection

    Scans the artifact's own text for instructions aimed at your agent rather than at you.

  • passLicense

    Whether the source repository declares an SPDX license permissive enough to redistribute.

How the grade is calculated

Each check contributes 0 points when it passes, 1 when it warns, and 2 when it fails. The total maps to a letter:

  • Aevery check passed
  • Bone warning
  • Ctwo warnings
  • Dprompt injection or body integrity failed, or three warnings
  • Fone of those failed, and something else is wrong

These are automated hygiene checks, not a security audit, and not a dependency or vulnerability scan. A grade of A means nothing was flagged — not that the artifact is safe.
