Prompt Sensei is a quiet, local-first prompt coach for Claude Code and Codex. It gives stage-aware feedback, rewrites rough prompts into better ones, looks back on local history when you ask, and helps you practice one habit at a time.

It is built as a real host-integrated skill, not just a markdown rubric: Prompt Sensei supports hook-based observe comments, opt-in auto-observe hooks, hash-only prompt captures, quiet Stop-hook persistence, and compact-safe continuity where the host exposes the lifecycle events.

No cloud. No telemetry. No leaderboard. No raw prompt archive.

Prompt Sensei's score is a coaching signal, not an objective grade or a guarantee of better output. The real test is whether the improved prompt produces a more useful first draft, fewer clarification turns, safer agent behavior, and easier verification.

Why This Exists

AI coding agents do real work: they edit files, run commands, and make implementation choices. A vague prompt does not just produce a vague answer; it can produce broad edits, hidden assumptions, and extra revision loops.

Prompt Sensei is built around a simple belief:

- Prompting is an engineering skill.
- Engineering skills improve through feedback.
- Feedback should be kind, specific, private, and useful.

It does not treat fix this test as a bad prompt. It treats it as an early-stage prompt, then teaches the next step.
