Agents
The OmO agent catalog and how the work is split.
OmO ships a small cast. Four agents are the lanes you enter on purpose; the rest are specialists Sisyphus calls when it needs them.
Core Ordering
The four primary agents have a stable tab order in OpenCode: Sisyphus, Hephaestus, Prometheus, then Atlas. Other agents follow.
Sisyphus
Hephaestus
Prometheus
Atlas
Oracle
Librarian
Explore
Multimodal-Looker
Metis
Momus
Sisyphus-Junior
Tool Boundaries
These restrictions are part of the harness. They stop "smart" agents from doing unsafe work in the wrong role.
| Agent | Constraint |
|---|---|
| Oracle | Read-only consultation. No writes, edits, or delegation. |
| Librarian | Research-only. No writes, edits, or delegation. |
| Explore | Search-only. No writes, edits, or delegation. |
| Multimodal-Looker | Media analysis, read-focused. |
| Atlas | Orchestrates plan execution but delegates implementation units. |
| Sisyphus-Junior | Implements one assigned unit and must verify before returning. |
Category Workers
When task receives a category, OmO spawns a Sisyphus-Junior-like worker tuned for that domain. The category picks the model profile; skills add instructions and MCPs.
| Category | Worker behavior |
|---|---|
visual-engineering | Frontend/UI/design work. Pair with frontend-ui-ux and browser verification. |
ultrabrain | Hard reasoning and architecture. Keep the prompt goal-oriented. |
deep | Autonomous research plus implementation. Good for hairy but coherent work. |
artistry | Creative or non-conventional approaches. |
quick | Small changes. Don't use it for visual work just because the diff is small. |
writing | Documentation and prose. |
Background Agents
Run specialists in the background when the main session can keep moving without the result.
task({
subagent_type: "explore",
load_skills: [],
run_in_background: true,
prompt: "Find all auth policy implementations and summarize file paths.",
});Use background mode for independent research. Stay synchronous when the result blocks the next implementation decision.
