Logfire Query

by pydantic · 2K installs

The skill

Logfire query is a skill for developers who query and analyse Logfire telemetry with SQL: traces, logs, spans and metrics, through the MCP query_run tool or the REST /v1/query API.

Only when you ask.

The habit

Daily summary of new errors.

↻ Runs by itselfevery morning

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

every morning. Runs in Claude Code routine.

  • ↻ every morning
  • 0 7 * * *

02

It checks its work

queries run with LIMIT. If a check fails, it tries again.

  • ✓every SQL query has a LIMIT
  • ✓time range is at most 14 days
  • ✓query_run returns without error

03

It remembers

daily error digests. The next run reads it first: yesterday's error counts by service and top exception types.

loops/logfire-error-digest-loop/run-log.md

One run, step by step.
Then it stops.

Stop ruleStops after five queries per run.

  1. 01

    Classify the route

    Treat the run as query analysis, not a Logfire UI view.

  2. 02

    Query errors

    Call query_run on the records table for rows where is_exception is true, with a LIMIT.

  3. 03

    Group by service

    Count errors per service_name and list top exception_type values.

  4. 04

    Find slow spans

    Query spans with long duration, ordered by duration, with a LIMIT.

  5. 05

    Compare and log

    Compare with yesterday's digest and write new or growing errors to the log.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the Logfire Query skill helps.

Use it when

  • ✓ You look up errors in Logfire
  • ✓ You find the slowest spans
  • ✓ You add query code to a project

Skip it when

  • – You want to open the Logfire UI
  • – You do not use Logfire
