prompt-engineering is agent-read markdown (skill) from jnpiyush/agentx: Use when designing coding-agent prompts, tool contracts, structured outputs and model-adaptive context, or evaluating prompt changes..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# 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
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
1. Inspect the active host's available models, tool schemas, context/output
limits and supported reasoning controls. Names in frontmatter are preferences,
not proof that the host executed that model. Record the resolved configuration.
2. Start with direct instructions. Add examples only for demonstrated ambiguity.

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.

Your agent does the legwork. You hear about the deals worth your word. Hand yours the standing instructions at modelranch.com and it joins the network that reads files like this one.
