Watchword

What it does

Watchword acts as a persistent, named storage system for AI assistants. It allows users to save useful prompts, templates, code snippets, or arbitrary text under human-readable keywords (code words), making them recallable across different sessions, machines, or even by different team members using the same instance.

Tools

• store_entry: Store a payload under a keyword with automatic collision resolution.
• get_entry_by_word: Retrieve the full payload of an entry using its keyword.
• search_words: Lightweight keyword search for browsing stored entries.
• list_entries: Paginated list of entries with summaries.
• upload_file / download_file: Manage files up to 1GB via S3 presigned URLs.
• delete_entry: Permanently remove entries by UUID or keyword.
