Create, update, review, or discuss an LLM prompt — a system prompt, a skill, or an agent. Use when writing or improving a prompt, discussing a skill or agent, diagnosing prompt failures, or when the user says a prompt needs work.
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
A prompt states a goal and gets out of the way. Everything else in it is load — spent on every run, taken from the attention the model would otherwise put on the work — so each line has to buy more than it costs. What follows decides three things: whether a line exists, where it sits, and how it is worded. ## Where a line came from Ask this before asking whether the line helps. A line can be true, relevant, and still worth cutting, so usefulness does not settle it. Provenance does, and you can answer it from memory: - **The user ruled it** — a decision, preference, or constraint they stated. Nothing derives it. Keep. - **The world holds it, out of the run's reach** — an unwritten convention, a failure you observed, a fact outside what the run will read. Keep, and prefer a pointer to the source over a copy that can go stale. - **It counteracts a default you have watched the model take** — keep, when the default is observed rather than feared. - **You worked it out from material the run will also read** — cut. A conclusion available in the corpus is one the run reaches itself, so writing it down buys nothing and spends load on every invocation. …

How to install
mdr add doodledood/manifest-dev/prompt-engineering@sha256:57e93654888a3403The line at the top of this page pins the label git:20261001.e957e91, 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.
