Use when writing instructions that guide Claude behavior - skills, CLAUDE.md files, agent prompts, system prompts. Covers token efficiency, compliance techniques, and discovery optimization.
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
# Writing Claude Directives **REQUIRED:** Also apply ed3d-extending-claude:prompt-security-hardening when using this skill. Directives that demonstrate unsafe secrets handling teach agents to leak secrets. ## Core Principles **1. Claude is smart.** Only write what it doesn't already know. Challenge each line: does this justify its token cost? **2. Positive > Negative framing.** "Don't do X" triggers thinking about X (pink elephant problem). Say what TO do, not what to avoid. ```markdown # Bad: triggers the behavior Don't create duplicate files # Good: directs to correct behavior Update existing files in place ``` **3. Context motivates compliance.** Explain WHY, not just WHAT. Claude generalizes from motivation. ```markdown # Less effective NEVER use ellipses # More effective Your response will be read aloud by a text-to-speech engine, so never use ellipses since the TTS engine cannot pronounce them. ``` **4. Placement matters.** Instructions at prompt start and end receive higher attention. Critical rules go at boundaries. **5. ~150 instruction limit.** More instructions = uniform degradation across ALL rules. Prune ruthlessly. …

How to install
mdr add ed3dai/ed3d-plugins/writing-claude-directives@sha256:ca11f14d53f25728The line at the top of this page pins the label git:20260319.b0d6d88, 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.
