Use when improving, reviewing, or writing a prompt for frontier models (Claude 4.6+/Opus 5/Fable 5, GPT-5.x class) - delegation briefs, agent goals, system prompts, CLAUDE.md files, or skills. Triggers on "improve this prompt", "why did this prompt fail", "write the kickoff for", "review my CLAUDE.md/skill", or /advanced-prompt-improver. For quick single-message polish the older prompt-improver also works; this skill is the researched 2026 frontier-model version.
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
# Advanced Prompt Improver Research-grounded (2026 sources at bottom). The one-line thesis, confirmed by Anthropic, OpenAI, and practitioner evidence: frontier models supply the procedure, diligence, and planning by default, so a prompt's job has narrowed to intent, done-state, hard constraints, authorization, and grounding sources, stated exactly once. Specificity did not die; it moved from HOW to WHAT. ## Step 0: Classify before touching anything - **Conversational or exploratory ask**: leave it alone. Deliberate vagueness is a technique; a vague question gives the model room to surface things you would not ask about. - **Small task** (diff describable in one sentence): the fix is usually deletion, not addition. No plan ceremony. - **Delegation or agentic brief** (multi-step, tools, unattended time): apply the six slots below. Full spec in ONE turn; drip-feeding requirements across turns measurably reduces performance. - **Standing prompt** (system prompt, CLAUDE.md, skill): apply the delete list hardest. Bloated standing instructions cause the model to ignore the rules that matter. Deletion test per line: "would removing this cause a mistake?" If not, cut. …

How to install
mdr add ericpardee/agent-files/advanced-prompt-improver@sha256:c7d479cfb45c2854The line at the top of this page pins the label git:20260727.291aeae, 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.
