Evaluates and scores Claude prompts and system prompts using a six-dimension Scorecard with anchored 1-5 rubrics. Trigger on: "review my prompt," "score this prompt," "rate my prompt," "evaluate this prompt," "improve my prompt," "what's wrong with my prompt." Also trigger on: "why isn't my prompt working," "my prompt produces bad output," "help me fix this prompt," "is this prompt any good." Scorecard covers Objective Clarity, Context Specificity, Reasoning Fit, Output Precision, Behavioral…
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 Validation > **Calibration:** Tier 2 (Sonnet-graceful) — designed against Opus 5.5 + Sonnet 5.5 dual-primary. Runs on Haiku 5.5 at `high` effort with less depth on multi-dimensional analysis; fallback-graceful on Opus 5 / Sonnet 5; legacy-graceful on Sonnet 4.6. Start at the model's default effort (`medium` on Opus 5.5 and Sonnet 5.5 in Claude Code; `high` for Sonnet 5.5 on the Claude API) and re-run an effort sweep on your own evals rather than carrying a setting over. See repository README for model compatibility. Evaluate whether a prompt is well-constructed, diagnose why it underperforms, and fix it systematically. This Skill treats prompt evaluation as a structured discipline — score the architecture, test the output, trace failures to their root layer. ## Reasoning discipline …

How to install
mdr add drayline/rootnode-skills/prompt-validation@sha256:66dad57e0a29f05bThe line at the top of this page pins the label v6.0.0, 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.
