The premier prompt workflow manager for Claude Sonnet 5 & Opus 5 designed for developers
and AI creators who push the limits of long-context coding agents,
Artifacts generation, and multi-step system prompt orchestration.
Store, organize, and 1-click inject your Claude prompt templates with
the /ps slash command — built with local-first IndexedDB privacy
so your proprietary code and system prompts never leave your machine.
PromptShifu (formerly PromptCat) is the official Chrome extension behind this manager.
Claude Sonnet 5 & Opus 5 thrive on detailed, long-context system prompts. Store complete coding agent personas, multi-file refactoring workflows, and Artifact generation templates — all with full 200K-token fidelity. Switch between your "senior Rust reviewer," "React architecture advisor," and "Python data pipeline architect" presets in one click.
Type /ps directly in the Claude.ai input box to trigger instant
prompt search and injection. Your saved Claude prompts appear inline — select one
and it fills Claude's input instantly. Assign custom slash commands
like /refactor or /architect for your most-used
workflows. Zero tab switching, zero copy-paste friction.
Every Claude prompt, system preset, and code template stays in your browser's IndexedDB — PromptShifu has zero server-side storage and zero access to your prompt content. For developers working with proprietary codebases, NDA-bound projects, or sensitive architecture decisions: your intellectual property never leaves your machine.
Add PromptShifu from the Chrome Web Store — it pins a side panel icon next to your address bar. No account or sign-up needed. Works on Chrome, Edge, and Brave.
Navigate to claude.ai, then click the PromptShifu icon. The prompt manager opens as a persistent side panel — Claude on the left, your prompt workflows on the right.
Save coding agent system prompts, Artifact generation templates, code review checklists, and multi-step workflow presets. Organize with tags, folders, and {{variable}} placeholders for reusable templates.
Type /ps in Claude.ai's input box, search your prompt by keyword, and hit Enter — your full system prompt or coding workflow appears in Claude instantly, ready for Claude Sonnet 5 & Opus 5 long-context processing.
Yes. PromptShifu is built specifically for long-context workflows. Claude Sonnet 5 & Opus 5 support up to 200K tokens of context, and PromptShifu stores and injects even the longest coding agent system prompts, multi-file refactoring templates, and artifact generation workflows without truncation. The side panel keeps your prompt library accessible while you work inside Claude.ai — no copy-paste, no context loss. Whether you're feeding Claude a full codebase for refactoring or a detailed multi-step system prompt for artifact generation, PromptShifu handles it seamlessly.
No. PromptShifu uses a 100% local-first IndexedDB architecture — your prompts, system instructions, and code snippets never leave your browser. PromptShifu has zero server-side storage and zero access to your prompt content. When you inject a prompt into Claude.ai, it goes directly from your local browser storage to the Claude input box. For developers handling proprietary codebases, NDA-bound client projects, or sensitive system architecture decisions, this means your intellectual property stays on your machine. Optional Google Drive sync encrypts data through your own Google account if you need cross-device access.
Type /ps directly in the Claude.ai chat input box to trigger PromptShifu's instant prompt search. A dropdown appears showing your saved Claude prompt templates — coding agent presets, system prompt configurations, artifact generation workflows, and more. Select one and it fills the Claude input instantly. You can also assign custom slash commands (e.g., /refactor for your Rust refactoring preset, /review for your code review checklist, or /architect for your system design workflow) to your most-used Claude workflows for even faster access — all configurable from the PromptShifu side panel.
