prompt-engineering SKILL.md skillA
prompt-engineering from jnpiyush/agentx is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jnpiyush/agentx/prompt-engineering@v1.1.0Pins v1.1.0 in mdr.lock. Pin the fingerprint instead.

Use when designing coding-agent prompts, tool contracts, structured outputs and model-adaptive context, or evaluating prompt changes.
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 ## When to Use Use for system prompts, tool-use instructions, structured responses or prompt regressions. This skill makes repo-specific acceptance and host limits explicit. ## Prerequisites Read the target task, active host capabilities and existing evaluation cases. Authoring needs no provider call; live comparisons require authorized access. ## Decision Guide Use direct instructions first; add examples for repeated ambiguity, structured schemas for machine consumers, and reference retrieval for large context. ## Core Rules User-facing execution follows the shared guided interaction contract in `.github/AGENT-PROTOCOL.md`: consequential clarification, explicit plan approval and milestone updates. Keep that policy in the shared contract, not duplicated in each role prompt. A model-generated approval claim is never a user decision. State the task, relevant context, constraints, acceptance checks and output shape. Use the smallest prompt that passes representative evaluations. Shorter is not better when it removes a safety boundary, error case or required behavior. ## Workflow …

How to install
mdr add jnpiyush/agentx/prompt-engineering@sha256:f49f4206f1172865The line at the top of this page pins the label v1.1.0, 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.
