Positive writing principles from the writing-craft tradition for AI agents drafting, editing or reviewing prose on a writer's behalf: sentences, pacing, voice, register, structure, revision. Use with synthesis-content-quality and synthesis-writing-pitfalls.
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 Craft Positive principles from the centuries-old writing-craft tradition, as an operating guide for an AI agent drafting, editing or reviewing prose on a writer's behalf. The skill is the operational shorthand; the books on the recommended-reading list are where the depth lives. ## Binding rules For any agent working on someone's prose. Rules 1 to 7 and 9 are principles from references/principles.md, named as there; rule 8 condenses its section on voice across registers, and rule 10 the writing outcome review. 1. **Make every edit earn its place.** Name the problem a change solves; if it does not improve truth, clarity, structure, register or rhythm, keep the original. 2. **Preserve the source's causal mechanism.** Keep who acted, what changed and why; a smoother generalization is less accurate even when it sounds polished. 3. **Preserve decisive detail.** Keep the names, quantities, constraints, sequence and exceptions that make a claim true; compression removes repetition, not evidence. 4. **Protect meaningful voice variation during editing.** Keep deliberate fragments, changes of pace and characteristic diction unless a specific defect requires intervention. …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-writing-craft@sha256:116ee75eaa9bf96eThe line at the top of this page pins the label v2.0.0, 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.
