prod-telemetry

A way to query production telemetry, meaning records about how a live application runs, from traces, database data, and product analytics.

In plain words
What is it for?
Use it to investigate production errors and slow requests, understand feature usage and churn signals, and check whether a deployment changed real-world behavior.
Why use it?
It avoids searching separate dashboards or rediscovering the structure of each data source when investigating live-system behavior.

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

prod-telemetry 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Production telemetry access

All three stores are queryable through the Executor MCP's connected integrations — no dashboards or credentials needed. Verify the connection exists with connections.list if a call fails.

Axiom traces (axiom_mcp)

Tool: axiom_mcp.user.axiomMcpOAuth.querydataset — the argument is apl (NOT query). Dataset: ['executor-cloud'] (worker spans; browser spans join the same traces via traceparent).

Field layout (the part you'd otherwise rediscover by failed queries):

  • Custom span attributes live under the JSON map ['attributes.custom'], NOT as top-level attributes.* columns. Read with ['attributes.custom']['mcp.tool.name']. A nonexistent top-level field is a hard query error ("invalid field"), not an empty result.
  • Span status: ['status.code'] ("OK"/"ERROR"), ['status.message'].
  • Exceptions: the events column carries exception.type / exception.stacktrace JSON.
  • OTel basics are top-level: name, trace_id, span_id, parent_span_id, duration, _time.

Span names worth querying (and their custom attrs):

  • mcp.execute / mcp.execute.resumemcp.execute.mode (pausable/inline), mcp.execute.code_length, and mcp.execute.outcome (ok/fail/paused) with, on failures, mcp.execute.error_kind (type_error | reference_error | syntax_error | range_error | tool_error | timeout | resource_limit | serialization_error | thrown | unknown). Sandbox script failures ride the MCP success channel, so status.code stays OK — filter on these attributes, not span status. Spans from before the attributes shipped carry neither; absence is not success. Also mcp.execute.result_chars (compact-JSON size of the returned value, pre-truncation; -1 = unmeasurable), mcp.execute.log_chars, mcp.execute.emitted — the dump-vs-narrow signal (the model preview truncates at 30k chars, so result_chars > 30000 means the model tried to pull a truncated blob into context).
  • executor.tool.executemcp.tool.name (full address), and since PR #992: executor.tool.outcome (ok/fail), executor.tool.error_code, executor.tool.error_status, executor.tenant, executor.subject.
  • mcp.tool.dispatchmcp.tool.name (sandbox path), mcp.tool.integration, same outcome attrs.
  • plugin.openapi.invokeplugin.openapi.method / path_template / base_url, and since PR #992 http.status_code.
  • mcp.request (outer) — mcp.auth.organization_id, mcp.auth.account_id, mcp.tool.name, CF edge fields (cf.country…), MCP client fingerprint (mcp.client.name…), and on managed-cloud execute/execute-action calls mcp.execute.code (the script itself, capped at 10k chars — cloud-only content capture; local/self-host telemetry never records content).

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.

prod-telemetry is a skill published in the GitHub repository UsefulSoftwareCo/executor (3,466 stars, last pushed yesterday), licensed MIT. It adds 75 tokens to every session and 1,607 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
