Agents tell you when they get stuck

A report in Definable is what an agent files when it can't do what someone asked: a missing tool, unclear instructions or a failure. You read reports on the agent's Reports tab, and Fix with Builder drafts a change for you to review and publish. Builder never acts on a report on its own.

Reports at work
In Acme's demo workspace an agent meets a request it can't handle and files a report. Fix with Builder opens it, Builder proposes a draft change, and the report is resolved once the fix is published.

How reports work

When an agent can't do what someone asks, it tells Builder. You read the report, and Builder proposes the fix for you to publish.

At a glance

  • One report per run
  • Test runs save nothing
  • Open or resolved
  • Drafts only, you publish
  1. 01

    The agent files it quietly

    No tool or app for the job, instructions that don't cover the case, or a failure it can't get around: it files one report and keeps helping. The person it's talking to never sees it.

  2. 02

    Three kinds, said plainly

    Missing capability, unclear instructions or failure, with a summary of what was asked and what would have let it do the job.

  3. 03

    Fix with Builder

    It opens your Builder chat with the report. Builder reads the run and the conversation, finds the cause and proposes a draft change.

  4. 04

    You decide

    Builder never starts on a report by itself and never publishes. You publish the fix, then mark the report resolved, or reopen it later.

  • How do I change an agent safely?
