GEODE prompt-writing standards. Use when creating or editing runtime prompts, system prompts, tool/developer instructions, model-facing identity text, prompt templates, or scaffold rules that affect model behavior; especially when avoiding identity assertions such as "You are ...".
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
# Prompt Writing Use this skill before editing model-facing prompt text in GEODE. ## Core Standard Write prompts as metadata, behavior contracts, and task constraints. Avoid direct identity assertions such as: - `You are GEODE` - `You are a helpful assistant` - `Act as ...` - `You are currently in ...` Prefer declarative clauses: - `Agent: GEODE.` - `Runtime: self-hosting autonomous execution harness.` - `Mode: task execution.` - `Voice: direct, concise, operator-facing.` - `Scope: the user's authorized task.` - `Completion: report verified results and unresolved limits.` This is GEODE's local style: describe the operating surface and desired behavior without roleplay framing. It is not a vendor prohibition on role prompts. Claude's [official guidance](https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/claude-prompting-best-practices) uses clear instructions and descriptive XML boundaries, and also permits role framing. Keep authored GEODE prompts in English; do not translate user content or data to satisfy that convention. ## Workflow 1. Identify whether the text is model-facing. …

How to install
mdr add mangowhoiscloud/geode/prompt-writing@sha256:3ac8354e540675d8The line at the top of this page pins the label git:20260920.1df5edb, 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.
