Built-in tools

Timeouts and truncation

Open Tools in the left menu:

• Timeout — empty means the built-in default; a custom value is used as-is.
• Output truncation — beyond the line or byte limit, output is truncated and the full version is written to disk, so a single command cannot flood the context.
• Clearing a field restores the default; changes apply immediately.

Use in an agent

In the Agents editor, tick tools under Built-in tools. Follow least privilege.

Advice

• Read-only tasks do not need file-writing or command tools.
• Prefer background execution for long work.
• Pair chatty commands (logs, builds) with truncation and read the spilled file when needed.

FAQ

A tool is unavailable — confirm it is ticked and that the session has a sandbox (execution tools need one).

Commands time out — use background execution or raise the timeout.

Output is truncated — expected; the full output is on disk for the agent to read.
