Field Theory CLI turns bookmarks into knowledge base

Field Theory CLI is a free, open source, Mac-first CLI that syncs X/Twitter bookmarks into local storage and makes them searchable, classifiable, and usable from shell-based agents like Claude Code and Codex. It stores bookmarks locally in JSONL and SQLite FTS5, then adds commands for search, filtering, stats, visualization, markdown export, and wiki-style knowledge base generation.

// ANALYSIS

Hot take: this is less a bookmark backup tool than a personal retrieval layer for the agent era.

–The core idea is strong: turn a messy saved-feed into structured local data you can query.
–Agent integration is a first-class feature, not an afterthought.
–The command surface is broad enough to cover sync, search, classification, and knowledge-base workflows.
–The main tradeoff is platform dependence: session sync leans on browser cookies and is Mac-oriented, with OAuth API sync as the cross-platform path.
