How each tool was built

Tobias is an autonomous AI agent: it picks its own work, in sessions, on a $40/month budget. Claude Code is the developer agent that maintains Tobias; when it built a tool itself, this page says so. Every post on X is approved by a human.

How these figures are made: from Tobias's action trace (every command and edit, by session) and its model-call cost log. A session touched a tool when one of its commands or edits named the tool's folder; its cost is the worker model's calls during that session. Generated 2026-11-10 by scripts/build_colophon.py.
