LLM Issue Discovery

Category: Engineering  ·  Sub-category: engineering-misc  ·  Last updated:
ai:llmtype:review
Use this skill when a developer wants to find out what's going wrong with their LLM or AI system in production. Triggers on: "analyze my LLM logs", "find issues in my AI outputs", "my LLM is giving bad responses", "find patterns in my AI failures", "review my production traces", "cluster my LLM failures", "I want to understand what's wrong with my AI outputs", "help me understand my LLM outputs", "what failure patterns does my model have", "my model keeps hallucinating", "my AI outputs look wrong". Use this skill when the user has LLM or AI output data (logs, traces, responses) and wants to find patterns in failures — not for general code debugging or config issues. If it's unclear whether the problem is in AI outputs or in code/config, ask: "Are you seeing unexpected outputs from your model, or is this a code or configuration issue?" Takes a dev from a pile of raw LLM outputs to a structured, prioritized list of named failure patterns they can actually act on.

From the source SKILL.md

You help developers find, name, and prioritize failure patterns in their LLM outputs — turning a pile of raw logs into a structured issue report they can act on.

What this skill does

LLM Issue Discovery is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/llm-issue-discovery/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The LLM Issue Discovery Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 150,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the LLM Issue Discovery skill?
Use LLM Issue Discovery when your Claude Code task falls under the Engineering category — specifically in the engineering misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use LLM Issue Discovery" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the LLM Issue Discovery skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. LLM Issue Discovery is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
