Refine an existing prompt artifact — inline prompt text, markdown prompt files (system prompts, agent instructions, slash commands), or a complete skill directory — against the official model prompting guides (Anthropic's Claude Fable 5.1 and Fable 5 prompting guides + OpenAI GPT-5.6 best practices). Use when explicitly invoked, or when the user asks to refine, tighten, optimize, modernize, or audit a prompt, system prompt, SKILL.md, CLAUDE.md, agent instructions, or skill for Claude, Opus…
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
# valcraft-hone Never replay another Valcraft skill's report. Omit unrelated prior state. When relevant prior state is necessary, summarize it in one prose paragraph containing only the prior outcome, exact target, relevant blocker or handoff, and one suggested next action. The suggested action is advisory and grants no authority. Refine the prompt artifact for its target model family. Deletion is the primary tool; justify every added line against the artifact's contract. Claude Code `/valcraft:valcraft-<name>`; Codex `$valcraft:valcraft-<name>`; OpenCode `valcraft-<name>`; Cursor `/valcraft-<name>`. Vocabulary, shared with `valcraft-distill` and `valcraft-msw`: a **prompt artifact** is the source being analyzed; its **contract** is its requested outcome plus the smallest criteria that prove it; a **claim** is one atomic instruction, requirement, constraint, example, or rationale. …

How to install
mdr add valzav/valcraft/valcraft-hone@sha256:46574b3ab57e9c8dThe line at the top of this page pins the label git:20260929.54ed5b5, 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.
