Trace Failure Classifier

Pair withAgent Trace Viewerto inspect timeline context before applying remediation actions.

What This Tool Does

Trace Failure Classifier is built for deterministic developer and agent workflows.

Classify failed agent trace events into root-cause buckets and output deterministic remediation guidance for incident response.

How to Use Trace Failure Classifier

  1. 1

    Paste structured trace events

    Provide traceId and event list including step name, status, latency, error code, and message for each failed or successful step.

  2. 2

    Run deterministic classification

    The classifier maps each failed event into root-cause buckets such as rate_limit, timeout, schema_mismatch, auth, or policy_block.

  3. 3

    Review failure distribution

    Inspect per-class counts, failed event details, and the primary cause to prioritize the first remediation action.

  4. 4

    Apply suggested remediations

    Use generated next actions to implement retries, payload trims, policy updates, or endpoint failover based on failure class.

  5. 5

    Replay and confirm recovery

    Replay the same event sequence after fixes and verify that failed-event count returns to zero before rollout resumes.

Frequently Asked Questions

Which failure classes are supported?
The classifier supports rate_limit, timeout, schema_mismatch, auth, policy_block, tool_unavailable, context_overflow, and unknown buckets.
How does classification work?
It uses deterministic pattern matching on error codes and messages from trace events, then maps each failure to a remediation action.
Can this replace full observability platforms?
No. It is a fast triage layer for pasted traces, designed to accelerate diagnosis before deeper platform-level analysis.
What if my trace has no failures?
The tool returns a healthy status with zero failed events and a monitoring recommendation instead of remediation tasks.
Is trace data sent to a backend?
No. Classification runs fully in the browser, so trace payloads remain local during analysis.
