system-prompts skillA
system-prompts is agent-read markdown (skill) from muselinn/musepi: Write system prompts, tool docs, and agent definitions. Project tag conventions + RFC 2119 keywords + dense compression. Use when authoring or editing any prompt the model reads..
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.
What the file says
# System Prompts House style: dense, imperative, RFC-keyed. Small models (≤2B; tiny/on-device, e.g. LFM2): MUST read [small-models.md](small-models.md). Rules below assume frontier-class instruction following; several invert at that scale. ## Tags Tags: authoritative, literal structural markers; meaning exactly matches name. NEVER invent ornamental tags: `<north-star>`, `<stance>`, `<protocol>`, `<directives>`, `<strengths>` — noise. |Tag|Purpose| |---|---| |`<conventions>`|Tag/RFC-keyword interpretation; contract.| |`<stakes>`|Correctness importance; domain framing.| |`<communication>`|Voice, tone, response shape.| |`<critical>`|Inviolable rules; place at START and END.| |`<completeness>`|Done definition; anti-shrink rules.| |`<yielding>`|Pre-yield checklist; block conditions.| |`<workflow>`|Numbered phases: scope → edit → decompose → work → verify.| ## Normative Language RFC 2119: full caps, no bold; all-caps form is the marker. |Keyword|Meaning|Replaces| |---|---|---| |MUST / REQUIRED|Absolute requirement|"always", "make sure", "ensure"| |NEVER (= MUST NOT)|Absolute prohibition|"do not", "don't"| …
