Diagnose a prompt against the six prompt-quality patterns and return a tighter rewrite with the reason for each change, a 0-6 score, or the best matching prompt from the Commander prompt library. Use when the user asks to fix, sharpen, improve or score a prompt, or wants a prompt for a task.
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
# $ccc-prompt-fix — a sharper prompt, with reasons
**CC Commander** · $ccc-prompt-fix · a rewrite that names each pattern it applied, so the next prompt is better without help.
Grounded in the Commander prompt library: `${CLAUDE_PLUGIN_ROOT}/lib/prompts-data/ccc-library.json` (`prompts[]` with `id`, `sdlc`, `cat`, `title`, `prompt`, `why`, `makeItStick`; `patterns[]`), compiled from `skills/claude-code-library/PROMPT-LIBRARY.md` and adapted from Anthropic's published Claude Code prompt library.
## When to use / when not to
- Use on demand to fix one prompt, score it, or find a library prompt for a task.
- Skip it when the prompt is already tight and the task is trivial; do not gold-plate a one-liner.
- The automatic per-turn nudge is the suggest engine's job (`$ccc-suggest`); this is the deliberate pass.
- To audit a whole instruction file (CLAUDE.md, a skill, an agent) for older-model prompting patterns, use `/doctor prompt-audit` or `$ccc-claudemd`.
## Modes

How to install
mdr add kevinzai/commander/ccc-prompt-fix@sha256:aca0802aca0e805cThe line at the top of this page pins the label git:20261013.fbe187d, 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.
