factory-prompting from nonlinear-xyz/factory-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nonlinear-xyz/factory-kit/factory-prompting@git:20260716.517fb94Pins git:20260716.517fb94 in mdr.lock. Pin the fingerprint instead.

Structured prompting with XML tags. A small named vocabulary (`instructions`, `context`, `input`, `output_format`, `examples`, `constraints`, `role`, `thinking`) that turns a prose ask into something the model can parse without ambiguity. Read whenever you're authoring a prompt by hand, designing a prompt template for production, or rewriting a flaky ask. Paired with `/prompt`, which converts a rough ask into the structured form.
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
# Factory prompting Each section leads with **Principle** (one sentence, model-agnostic), then **Why** (the constraint and the tradeoff), then **Recipe** (the canonical shape), and **Failure mode** when there's one to name. This skill governs how to *author* prompts; it doesn't tell you what to ask for. ## Why tags at all **Principle.** XML tags are unambiguous delimiters. They tell the model *what role each chunk plays* without relying on prose cues. **Why.** A bare prompt mixes roles: "Summarize these meeting notes (the meeting was with our vendor about Q3) — bullet points, max 150 words. Notes: …" The model has to infer which sentence is the ask, which is background, which is the material to operate on, and which is the output shape. It usually guesses right; under load, with long inputs, or with conflicting cues, it sometimes guesses wrong. Tags collapse the guess. `<instructions>` is the ask. `<input>` is the material. `<output_format>` is the shape. Each chunk has a labelled role, parseable independently. …

How to install
mdr add nonlinear-xyz/factory-kit/factory-prompting@sha256:5b86ae54501f22a3The line at the top of this page pins the label git:20260716.517fb94, 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.
