Claude Code Prompt Recorder

Claude Code Prompt Recorder

A Claude Code plugin that records every user prompt with a timestamp to `prompt_log.txt` in the project directory. Useful for reviewing your interaction history, tracking prompt patterns, and building a personal prompt knowledge base.

What It Does

Intercepts every prompt submitted to Claude Code via the `UserPromptSubmit` hook, and appends it with a timestamp to `prompt_log.txt` in the current working directory. The prompt is passed through unchanged — recording is completely transparent with zero impact on your workflow.

**Log format:**
