Agents

s-ai configures three coding agents from a shared canonical layer.

Agent	Home dir	Package source
opencode	~/.config/opencode	opencode-vim fork (@ai-sdk/openai-compatible)
omp (oh-my-pi)	~/.omp/agent	oh-my-pi flake
pi	~/.pi/agent	llm-agents.pi

Each enabled by default; disable per consumer with s-ai.agents.<name>.enable = false.

opencode

• Runtime + TUI via the upstream opencode home-manager module
• OMO (oh-my-openagent) plugin: Sisyphus agent system, team mode, subagents. Writes ~/.omo/omo.jsonc as a writable copy (not a store symlink) so OMO's migration system and runtime /settings edits work.
• plugin list from enabled plugins + OMO
• Providers rendered as opencode provider attrsets with modalities

Options:

Option	Default	Description
s-ai.agents.opencode.enable	true	opencode
s-ai.agents.opencode.omo	true	oh-my-openagent
s-ai.agents.opencode.extraSettings	{}	deep-merged last into programs.opencode.settings
s-ai.agents.opencode.extraOmoConfig	{}	deep-merged last into ~/.omo/omo.jsonc

omp (oh-my-pi)

• modelRoles: default from s-ai.defaultProvider/defaultModel; advisor/smol unarmed (null) unless you set advisorModel/smolModel
• memory (mnemopi), advisor, prewalk toggles
• vim-mode TUI, pi-style composer, nerd glyphs
• config.yml written as a writable copy by the upstream omp home-manager module (runtime /settings edits persist until the next switch)
• themes: s-ai-dark/s-ai-light from your palette; keybindings.yml from the keybindings option

Options:

Option	Default	Description
s-ai.agents.omp.enable	true	omp
s-ai.agents.omp.prewalk	true	strong model plans, smol role implements
s-ai.agents.omp.advisor	true	second-opinion reviewer on stop
s-ai.agents.omp.advisorModel	null	advisor role model id (unarmed when null)
s-ai.agents.omp.smolModel	null	smol role model id - prewalk exec, commits, background (unarmed when null)
s-ai.agents.omp.memory	true	local SQLite per-project memory (mnemopi)
s-ai.agents.omp.extraSettings	{}	deep-merged last into programs.omp.settings

pi

• programs.pi-coding-agent upstream module
• vim-motions-pi plugin (optional) for jk escape + OSC 52 yank
• mcp.json rendered with pi's lifecycle = "keep-alive" + directTools = true keys, and the canonical type = "remote" translated to { url, headers? } (pi rejects type = "remote")

Options:

Option	Default	Description
s-ai.agents.pi.enable	true	pi
s-ai.agents.pi.vimMotions	true	vim-motions-pi plugin
s-ai.agents.pi.clipboardCommand	null	OSC 52 command (e.g. pkgs.copy)
s-ai.agents.pi.extraSettings	{}	deep-merged last into pi settings

All agents share the same canonical prompts (AGENTS.md), skills (per-plugin routing), MCP servers, providers, and (for omp) theme.
