Design, debug, and refine prompts for LLM-based coding tools, agents, and pipelines. Use this skill when writing or rewriting a system prompt, agent persona, slash-command body, rule, or skill description; tuning a prompt that produces vague, incomplete, off-format, hallucinated, or over-/under-triggering output; choosing among techniques like XML tags, few-shot examples, role-setting, reasoning steps, or recap; debugging a model that ignores instructions, leaks information, or over-engineers…
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 A workflow and toolbox for writing prompts that steer modern LLMs reliably — system prompts, slash commands, skills, rules, agent personas, and one-off queries. ## Bundled references (load on demand) - **`references/snippets.md`** — read **when you need a copy-paste prompt fragment** for a recurring concern: anti-overengineering, parallel tool calls, default-to-action / do-not-act, investigate-before-answering, code-review coverage, frontend aesthetics, persistence across context windows, reversibility/safety, verbosity, long-document grounding. ~20 vetted blocks. - **`references/metaprompting.md`** — read **when a prompt under-performs and the cause is unclear**: full metaprompting template, filtering procedure for the model's suggestions, when to use vs. skip. - **`references/agent-persona.md`** — read **when designing or auditing the system prompt of an autonomous agent**: identity, autonomy posture, tool-use rules, editing constraints, full Friendly and Pragmatic personality blocks, final-message format, plan discipline. ## Workflow …

How to install
mdr add yelmuratoff/agent_sync/prompt-engineering@sha256:74bd4b6f640ddf11The line at the top of this page pins the label git:20261007.95b1395, 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.
