The product

Read every session. Name the behavior.

Flowlines turns raw agent traces into a flagged-sessions queue, the trace that proves each one, and a finding that names the root cause. Three surfaces, one workflow.

01 · Sessions

A queue of what went wrong, sorted by severity.

Every flagged session in one place, the agent, the behavior, the cost. No log spelunking, no dashboards to assemble. Open the one that matters and you're already in the trace.

  • Behavior labels, not generic error codes
  • Filter by agent, cohort, or finding

02 · Trace

The proof, turn by turn.

Every message, tool call, and result laid out in order, with the verdict pinned to the exact turn that broke. You see what the agent claimed against what the tools actually returned.

  • Tool args and results inline
  • Claim-vs-result checked automatically
03 · Findings

One root cause, every session attached.

Flowlines groups related sessions into a single finding, the pattern, who it hits, how often, and whether it's getting worse. You fix the cause once instead of chasing tickets one at a time.
