Error Log Summarizer

What this skill does

This skill directs the agent to ingest raw error logs — from a server, application, CI pipeline, or any other source — and produce a structured, de-duplicated summary. It groups repeated errors, counts occurrences, identifies the most frequent and most severe issues, and provides a root cause hint for each unique error type. The output gives you a clear picture of what's actually wrong without needing to scroll through thousands of log lines.

Use this when you have a dump of logs from a production incident, a CI failure, an error monitoring alert, or a server that's behaving oddly.

How to use

Claude Code / Cline

Copy this file to .agents/skills/error-log-summarizer/SKILL.md in your project root.

Then ask:

• "Use the Error Log Summarizer skill on these logs."
• "Summarize this error output from our production server using the Error Log Summarizer skill."

Paste the raw logs directly into the message, or provide a file path if the logs are in the repo.
