Personal Data Harvester

Helps Claude autonomously build and maintain a local pipeline that collects a user's personal content history across platforms, stores it in a structured SQLite database, and keeps it fresh over time.

Core philosophy

• User's own data, user's own device. All collection happens under the user's authenticated session or from locally cached files. Never store credentials; reuse existing browser sessions.
• Graceful degradation. Each platform has a primary and fallback strategy. If automation breaks (platform redesign, rate-limit), fall back to file import without losing prior data.
• Privacy-first. Data stays local by default. No uploads unless the user explicitly requests it.
