Claude Code, opencode, Cursor, Antigravity, Codex, Copilot and Grok write down everything they do: every file read, every tool call, every token spent. Almost nobody reads it. threadle does, and draws it as one graph. Walk the timeline, diff what changed, trace lineage across runs. Then hand context from one agent to another and wire sessions into pipelines. Localhost, no account, no telemetry, no outbound requests.
