synthesis-content-quality skillA

synthesis-content-quality is agent-read markdown (skill) from synthesisengineering/synthesis-skills: The most comprehensive open-source slop detection system available. Catches AI-generation patterns by model family (Claude, GPT, Gemini, Llama, Grok, DeepSeek, Mistral, Qwen), substance and depth failures (beautiful word salad), and the full v3.1.0 catalog refreshed. Includes causal-layer attribution, combined-signal fingerprints, two-axis calibration, ESL safe-harbor, and zone-conditional detection (artifact mode vs full-response mode). Spans the entire LLM era through the compounding-archive p.

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.

How to install

Latest version
mdr add synthesisengineering/synthesis-skills/synthesis-content-quality@v4.2.0
Exact content
mdr add synthesisengineering/synthesis-skills/synthesis-content-quality@sha256:6c0b9a898972351e

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.
