A free Claude skill that rewrites your prompt into an optimized format Claude understands the first time, so you are not stuck re-explaining yourself and burning through usage.
Every retry resends your whole conversation. Five rounds of "no, I meant..." means you paid for the same context five times. Promptmaster kills the retries at the source:
- Rewrites your raw ask into a specific one before answering it. Vague in, exact out, then it executes the optimized prompt in the same turn.
- Audits against 35 credit-waste patterns (waste-patterns.json): the specific ways prompts force retries, from "no deliverable named" to pattern #35, redundant context.
- Remembers the decisions you already made (decisions.md): lock a preference once (voice, length, emojis, stack) and it is applied to every future request. Contradictions get blocked, not silently absorbed.
The whole move, one line each:
raw: write me something for instagram, idk
rewritten: Write a 30-day Instagram plan for a local coffee shop with 8k
followers. One table: week, theme, 3 post ideas. Under 400 words.
Install
The fast way: paste this repo link into Claude and ask it to install the
skill. Then type /promptmaster before any request.
https://github.com/Jakeschincariol/promptmaster-skill
Install this skill, then confirm /promptmaster works.
Manual, for Claude Code:
git clone https://github.com/Jakeschincariol/promptmaster-skill
cp -R promptmaster-skill/.claude/skills/promptmaster ~/.claude/skills/
Project-local instead: copy the same folder into your repo's
.claude/skills/. No Claude Code? Paste SKILL.md at the top of any
Claude chat and it runs as a mode.
Use
/promptmaster write me something for instagram, idk
You get a short receipt (what was rewritten, which waste patterns were flagged, which locked decisions applied), then the finished answer. Standing preferences:
lock: voice = casual, like I talk
unlock voice
decisions
