[Bug]: OMO agents (Sisyphus, Prometheus, Atlas, etc.) missing after upgrading to OpenCode 1.3.14

[regulusleow]

Prerequisites

• I will write this issue in English (see our Language Policy)
• I have searched existing issues to avoid duplicates
• I am using the latest version of oh-my-opencode
• I have read the documentation or asked an AI coding agent with this project's GitHub URL loaded and couldn't find the answer

Bug Description

After upgrading to OpenCode 1.3.14, all Oh My OpenAgent agents (Sisyphus, Prometheus, Atlas, etc.) are missing. Only the default OpenCode agents (plan and build) are available.

I have tried:

1. Completely uninstalling both OpenCode and OMO
2. Reinstalling using the following commands:

   brew install anomalyco/tap/opencode
   bunx oh-my-openagent install

After reinstallation, the OMO agents are still not available.

Steps to Reproduce

1. Upgrade OpenCode to version 1.3.14 (from previous version)
2. Run OpenCode
3. Check available agents
4. Observe that OMO agents (Sisyphus, Prometheus, Atlas, etc.) are missing

Alternative reproduction:

1. Uninstall OpenCode and OMO completely
2. Install OpenCode 1.3.14: brew install anomalyco/tap/opencode
3. Install OMO: bunx oh-my-openagent install
4. Check available agents
5. Observe that only default agents (plan, build) are present

Expected Behavior

All OMO agents should be available, including:

• Sisyphus (main orchestrator)
• Prometheus (planner)
• Atlas (and other specialized agents)

Actual Behavior

Only default OpenCode agents (plan and build) are available. All OMO-specific agents are missing.

Same issue. For absolutely new session all works fine, but for any old sessions are only Build/Plan.

[vinayakkulkarni]

Yes, can confirm it is broken... only Build / Plan available

Opus fixed. Probably it was:

The error was the node-gyp CI path error:

Cannot find module '/home/runner/_work/opencode/opencode/node_modules/.bun/node-gyp@12.2.0/node_modules/node-gyp/bin/node-gyp.js'
This happens because OpenCode v1.3.14 switched from bun to @npmcli/arborist for plugin installation. When arborist.reify() tries to build native dependencies (like @ast-grep/napi), it uses a node-gyp path that was baked in during OpenCode's CI build — a path that doesn't exist on anyone's local machine.

The fix: generate a package-lock.json in the plugin's cache directory so that arborist.loadVirtual() succeeds and skips reify() entirely, bypassing the broken node-gyp path.

Just got hit by this too. Was scared because none of my models were working, only the build agent showed up, no MCP servers, no custom configs. I had just made some junction links to free up disk space so I thought I broke everything.
Turns out it was 1.3.14 all along. Fixed with:

npm install -g opencode-ai@1.3.13

Also had to force reinstall oh-my-openagent since the package renamed from oh-my-opencode to oh-my-openagent:

npm install -g oh-my-openagent@latest --force

[jralph]

Nuking the ~/.config/opencode/package-lock.json, ~/.config/opencode/node_modules and ~/.cache/opencode/packages files/folders fixed it for me. Nuked these, reopened opencode, all good.

[regulusleow]

Upgrading opencode to v1.3.15 fixes this. To add some code-level detail to @quanturbo's analysis, v1.3.15 includes two fixes:

1. Build time: mark node-gyp as external (build.ts)

+ external: ["node-gyp"],

Previously, Bun baked the node-gyp path into the compiled binary at build time (pointing to the CI environment path /home/runner/_work/...), which doesn't exist on any user's local machine, causing Arborist to fail when it tried to resolve the module.

2. Runtime: add ignoreScripts: true to Arborist (npm/index.ts)

+ ignoreScripts: true,

This prevents Arborist from running post-install scripts (e.g. native module compilation) during dependency installation, so node-gyp is never invoked.

[regulusleow]

Since upgrading opencode to v1.3.15 resolves the issue, I'll go ahead and close this.

However, I just upgraded, but the issue remains unresolved. My AI diagnosed it as a proxy issue, and the new version of OC can no longer use a proxy

[rammiah]

Upgrade to opencode v1.4.0, still no agent is showing.

Have you ever tried removing the ~/.cache/opencode and ~/.cache/oh-my-opencode directories and re-entering opencode? Here are the steps I followed:

1. Delete the ~/.cache/opencode and ~/.cache/oh-my-opencode directories.
2. Run brew upgrade anomalyco/tap/opencode to update opencode to the latest version.
3. Run bunx oh-my-opencode install to reinstall to the latest version.
4. Run opencode to enter.
