llm-prompt-optimizer SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
llm-prompt-optimizer from hybridlabor-api/aos is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when improving prompts for any LLM. Applies proven prompt engineering techniques to boost output quality, reduce hallucinations, and cut token usage.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LLM Prompt Optimizer ## Overview This skill transforms weak, vague, or inconsistent prompts into precision-engineered instructions that reliably produce high-quality outputs from any LLM (Claude, Gemini, GPT-4, Llama, etc.). It applies systematic prompt engineering frameworks — from zero-shot to few-shot, chain-of-thought, and structured output patterns. ## When to Use This Skill - Use when a prompt returns inconsistent, vague, or hallucinated results - Use when you need structured/JSON output from an LLM reliably - Use when designing system prompts for AI agents or chatbots - Use when you want to reduce token usage without sacrificing quality - Use when implementing chain-of-thought reasoning for complex tasks - Use when prompts work on one model but fail on another ## Step-by-Step Guide ### 1. Diagnose the Weak Prompt Before optimizing, identify which problem pattern applies: | Problem | Symptom | Fix | |---------|---------|-----| | Too vague | Generic, unhelpful answers | Add role + context + constraints | | No structure | Unformatted, hard-to-parse output | Specify output format explicitly | …

How to install
mdr add hybridlabor-api/aos/llm-prompt-optimizer@sha256:a14431b1d3948558The line at the top of this page pins the label git:20260827.e9312a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
