prompt-engineering SKILL.md skillA
prompt-engineering from n-n-code/n-n-code-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add n-n-code/n-n-code-skills/prompt-engineering@git:20260905.4e6a0aaPins git:20260905.4e6a0aa in mdr.lock. Pin the fingerprint instead.

Prompt engineering workflow for designing, rewriting, debugging, evaluating, and optimizing LLM prompts, system prompts, developer prompts, few-shot examples, structured-output instructions, tool-use prompts, and prompt eval cases. Use when prompt behavior, reliability, safety, cost, latency, or model fit is the main task. Do not use for generic prose editing, model selection alone, or ordinary documentation work with no prompt artifact.
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
# Prompt Engineering Treat prompts as small behavioral specs. Improve them by naming the job, testing the behavior, changing one important thing at a time, and preserving the prompt's operating context. ## Activity And Authority - For review, return findings and evidence without rewriting files or changing a deployed prompt. A proposed revision may accompany findings when requested. - For drafting or implementation, change the requested prompt artifact within existing authority. Separate local evaluation from deployments, live tool actions, sensitive-data use, and metered runs that need additional authority. - Use the smallest useful output. A short rewrite need not produce a formal experiment report; a consequential behavior change needs explicit cases and honest evidence. ## Core Workflow 1. **Scope the prompt job.** Identify the target model or provider, audience, runtime surface, inputs, tools, output contract, constraints, and where the prompt will live. If the prompt belongs to a repo, inspect existing prompts, schemas, examples, tool definitions, evals, logs, and docs before asking avoidable questions. 2. **Define success before rewriting.** …

How to install
mdr add n-n-code/n-n-code-skills/prompt-engineering@sha256:53ed2219041d75d4The line at the top of this page pins the label git:20260905.4e6a0aa, 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.
