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.

## Build With Claude Prompt Engineering Claude 4 Best Practices

Source: https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/claude-4-best-practices
Path: 10-Prompting-Guides/build-with-claude-prompt-engineering-claude-4-best-practices.md

This guide provides specific prompt engineering techniques for Claude 4.x models, with specific guidance for Sonnet 4.5, Haiku 4.5, and Opus 4.5. These models have been trained for more precise instruction following than previous generations of Claude models.

For an overview of Claude 4.5's new capabilities, see What's new in Claude 4.5. For migration guidance from previous models, see Migrating to Claude 4.5.

General principles
Be explicit with your instructions

Claude 4.x models respond well to clear, explicit instructions. Being specific about your desired output can help enhance results. Customers who desire the "above and beyond" behavior from previous Claude models might need to more explicitly request these behaviors with newer models.

How to install

The exact contents, by fingerprint

mdr add johnzfitch/claude-wiki/10-Prompting-Guides/llms.txt@sha256:4bf2c83b8ebb21ae

The line at the top of this page pins the label git:20261024.48b8a60, 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.
