[Question]: Make Sisyphus agent optional for Build/Plan, prefer the default opencode Build/Plan agent

Question

Currently, the Sisyphus agent overrides the default Build/Plan agent provided by opencode. I would prefer to use the default Build/Plan agent by default, and only enable Sisyphus when I need to. Right now, I haven't found a method to temporarily toggle Sisyphus on/off.

If I disable Sisyphus with disabled_agents, there is no apparent way to enable it via @. However, agents like librarian, explore, etc., still display and function normally.

Is there a way to set the system so the default Build/Plan agent is used, and Sisyphus can be turned on only when specifically called?

Context

I tried setting my config as follows:

{
  "$schema": "https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/master/assets/oh-my-opencode.schema.json",
  "google_auth": false,
  "disabled_agents": [
    "Sisyphus"
  ],
  ...

With this configuration, Sisyphus is disabled but cannot be temporarily enabled with @. Other agents such as librarian or explore still function as expected.

/agent - then choose,,is this the way you want ?

/agent - then choose,,is this the way you want ?

It’s not a switch between “Build” and “Plan,” but rather a switch between “Build/Plan” and “Sisyphus/Plan-Sisyphus.”

[RunMintOn]

i mean youcan chose it manually，by /agent ,than use tab to switch, so youcan dicide which 1 of 4 modes you want
i never try to use it like this way ,is this the way you want?

he want to add ,not cover.

@RunMintOn After installing oh-my-opencode the build/plan completely disappeared for me, even when I check in /agents, i only see Sisyphus/Plan-Sisyphus, this is pretty invasive.

I want this feature too. I need 4 agnet Sysphus plan/build and origin plan/build , How Can I implement it?

You can bring back the original build agent with the following config:

{
  "sisyphus_agent": {
    "default_builder_enabled": true
  }
}

Confirmed that default_builder_enabled works, but easy to misconfigure.

The flag must be top-level in oh-my-opencode.json under sisyphus_agent, NOT inside the agents map. If you put it under agents, it gets ignored and looks like “it doesn’t work”.

✅ correct:

{
  "sisyphus_agent": { "default_builder_enabled": true }
}

❌ wrong:

{
  "agents": {
    "sisyphus_agent": { "default_builder_enabled": true }
  }
}

Also note default_builder_enabled only restores the build workflow (as OpenCode-Builder; the original build stays hidden when Sisyphus is enabled). To bring back the original plan agent too, you can set "replace_plan": false (default is true, which demotes/hides plan in favor of Prometheus (Planner)):

{
  "sisyphus_agent": {
    "default_builder_enabled": true,
    "replace_plan": false
  }
}

Might be worth clarifying this in docs: where sisyphus_agent lives + that OpenCode-Builder is the restored build agent name.

Thanks everyone, this config really does work. It’s just that the naming is a bit messy and chaotic.

[Eckii24]

I now introduced the following shell function in my config, to only enable oh-my-opencode when I want to. This way opencode work as before.

omo() {
    local config_file="$HOME/.config/opencode/opencode.json"
    local updated_json
    
    # Read and update the JSON:
    # - Create plugin array if it doesn't exist
    # - Add "oh-my-opencode" only if not already present
    updated_json=$(jq '.plugin = (.plugin // [] | if index("oh-my-opencode") then . else . + ["oh-my-opencode"] end)' "$config_file")
    
    # Execute opencode with the updated config as environment variable
    OPENCODE_CONFIG_CONTENT="$updated_json" opencode "$@"
}

Answer

Currently, when Sisyphus is in disabled_agents, it's fully disabled and can't be re-enabled via @.

Current Behavior

• disabled_agents: ["Sisyphus"] → Sisyphus fully disabled, default OpenCode build agent used
• Other agents (librarian, explore) work via @agent-name

Workaround

You can create two config files and switch between them:

1. oh-my-opencode.json - with Sisyphus enabled (default)
2. oh-my-opencode-minimal.json - with Sisyphus disabled

Or use environment-based config switching.

Feature Request Noted

Making Sisyphus opt-in (rather than default build agent replacement) is valid feedback. We'll consider adding a config option like sisyphus_as_default_build: false.

[DeluxeMonster]

Native build and plan agents should remain in the Tab rotation alongside Sisyphus/Prometheus, not be replaced by them.
Expected Behavior:
- Tab switching: build → plan → Sisyphus → Prometheus (all available)
- @ mentions: @librarian, etc. (all work)
- Default agent: User's choice (configurable, not forced)

 Current Behavior:
 - Tab only shows oh-my-opencode agents (Sisyphus/Prometheus)                                                                                          
 - Native build/plan are completely replaced                                                                                                           
 - No way to access them without uninstalling the plugin

Why This Matters:
Sometimes I want the lightweight, simple build agent for quick edits. Sometimes I want plan for read-only exploration. Sisyphus is great for complex orchestration, but it shouldn't be the only option.

 Proposed Solution:                                                                                                                                
 oh-my-opencode should **add** agents alongside native ones, not **replace** them. The plugin's agents could be:                                       
 - `Sisyphus` (primary, added)                                                                                                                         
 - `Prometheus` (primary, added)                                                                                                                       
 - `oracle`, `librarian`, etc. (subagents, as they are now)                                                                                            
                                                                                                                                                       
 This way users get the best of both worlds. 

I don't understand why the design choice was made to replace rather than extend. The "oh-my-zsh" analogy in the README suggests enhancement, not replacement - oh-my-zsh doesn't remove bash, it adds to it.
