thousandeyes-test-trace-correlation

thousandeyes-test-trace-correlation is a skill for Claude Code from thousandeyes/thousandeyes-ai-agents-toolkit. It costs 61 tokens per session (1,597 once invoked), scanned A, original, Apache-2.0.

A ThousandEyes investigation workflow for tracing failures in synthetic tests. Synthetic tests are scheduled checks that imitate requests or user actions to detect service problems.

In plain words
What is it for?
Use it to investigate failing or unreliable tests, correlate failures with services and traces, and propose code fixes after diagnosis and approval.
Why use it?
It connects failed checks with service maps, trace IDs, distributed tracing, and available observability systems to help identify the likely cause.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

thousandeyes-test-trace-correlation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ThousandEyes Test Trace Correlation

Use this skill to diagnose a failing ThousandEyes synthetic test end-to-end. Prefer evidence from ThousandEyes first, then correlate into available Observability Platforms. Only edit code after explicit user approval.

Use This Skill When

  • A ThousandEyes synthetic test is failing or flaky
  • The user wants service-map analysis or trace-based correlation
  • The user wants root-cause analysis tied to any Observability Platform available through MCP
  • The user wants a fix proposal after diagnosis, or approves implementing the fix

Required Behavior

  1. Read MCP tool descriptor JSON before using any MCP tool.
  2. Start from the test definition before interpreting metrics.
  3. Pull recent failure signals before forming a hypothesis.
  4. For http-server tests, always inspect distributedTracing.
  5. If distributed tracing is enabled, call get_service_map before jumping to Observability Platform correlation.
  6. If service-map data is missing or partial, continue with trace-ID fallback.
  7. Enumerate every Observability Platform MCP integration available in the current session before Observability Platform correlation. Do this even when common platforms (for example, Splunk or Datadog) are present.
  8. Once a valid traceId is available, verify and evaluate that trace across every enumerated Observability Platform MCP integration that supports trace or telemetry correlation.
  9. For each Observability Platform, also check telemetry tied to the ThousandEyes failing window. Do this even when direct trace lookup is available, because the extra telemetry helps explain the problem more completely.
  10. Do not stop after the first platform hit. Record positive hits, empty results, and platform/tool limitations.
  11. Tie Observability Platform findings back to both the ThousandEyes test and the recovered trace ID whenever possible.
  12. Ask for explicit approval before making code changes.

Inputs To Gather

  • Test reference: testId or exact/partial test name
  • Optional account scope: aid
  • Investigation window: window or start_date / end_date (default 24h)
  • Whether the user wants diagnosis only or diagnosis plus code fix

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
