Prompt Check

Category: General  ·  Sub-category: language-learning  ·  Last updated:
type:audittype:review
Audit a prompt file (system prompt, agent definition, voice script, chained workflow) across four lenses — conflict, dominance, gap, drift — plus an optional Turkish phonetic lens for voice agents. Use when the user invokes /prompt-check, asks to "audit a prompt", "check this prompt for contradictions / silent overrides / gaps / drift / voice readability", or passes a path to a prompt file for review. On first run in a repo, walks the user through a 5-question wizard and saves repo defaults to `.promptchecker.json`. Produces line-anchored findings as `report.md` + `findings.json` in an isolated run directory. Never modifies the original prompt file.

From the source SKILL.md

You audit a prompt file at the path supplied as $1. Read the prompt once, then dispatch each lens family to its dedicated subagent (static-lens-runner, drift-runner, tr-phonetic-runner). Merge their outputs in Phase 7. After the terminal summary (Phase 8), automatically enter the interactive review — Phase 9 (summary + decision parsing) and Phase 10 (action dispatch) are part of the default flow, not a separate command. Write all artefacts under an isolated run directory. Never modify the original prompt file except in Phase 10's applied step, governed by the SHA256 stale-audit guard.

What this skill does

Prompt Check is a community-contributed Claude Code skill in the language-learning sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/prompt-check/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user invokes /prompt-check, asks to "audit a prompt", "check this prompt for contradictions / silent overrides / gaps / drift / voice readability", or passes a path to a prompt file for review. On first run in a repo, walks the user through a 5-question wizard and saves repo defaults to `.
