Agent
Atlas is a todo list executor and multi-agent orchestrator. Given a work plan (.sisyphus/plans/{name}.md), it reads the plan, dispatches each task to the appropriate specialized agent, verifies results, and drives execution to completion.
Agent
Principal engineer for rubber ducking - finds holes in thinking, discusses architecture trade-offs, and pressure-tests ideas.
Agent
Hephaestus is a goal-oriented autonomous executor. Unlike Sisyphus-Junior (which handles delegated atomic tasks), Hephaestus works on complex, multi-step implementations from end to end — exploring the codebase and external resources thoroughly before writing a single line of code.
Agent
Librarian is a reference grep agent — it answers questions about open-source libraries by finding evidence with GitHub permalinks. Every claim it makes is backed by a direct link to the source.
Agent
Metis is a read-only pre-planning consultant. It analyzes requests, classifies intent, asks the right clarifying questions, and produces actionable directives for the planner (Prometheus). It does not implement or modify files.
Agent
Momus is a practical work plan reviewer. Its job is to answer one question.
Agent
Multimodal Looker is a read-only media interpretation agent. It receives a file path and a goal describing what to extract, then returns only the relevant extracted information. The main agent never processes the raw file — Multimodal Looker saves context tokens by doing the interpretation work instead.
Agent
Oracle is a strategic technical advisor with deep reasoning capabilities. It answers one question at a time, with one clear recommendation.
Agent
Prometheus is a planner, not an implementer. This is its fundamental identity constraint — not a suggestion.
Agent
Sisyphus-Junior is a focused task executor. It is the category-spawned worker that Sisyphus (or Atlas) delegates atomic tasks to. It does not orchestrate or plan — it receives a task and completes it.
