Description

Description

After upgrading from v1.3.7 to v1.3.8, npm plugins are no longer loaded. Running opencode plugin <name> reports:

No plugin targets found
Expected: "oc-plugin": ["server", "tui"] or tuples like [["tui", { ... }]].
This affects all npm-based plugins that don't declare the new "oc-plugin" field in their package.json, including oh-my-opencode-slim, opencode-mystatus, and superpowers.

Steps to Reproduce

  1. Install v1.3.8 (opencode upgrade v1.3.8)
  2. Have an npm plugin in config (e.g. "plugin": ["oh-my-opencode-slim"])
  3. Run opencode plugin oh-my-opencode-slim
  4. Observe: "No plugin targets found"

Expected Behavior

Plugins that export a valid Plugin function (the previous standard) should be loaded, or there should be a fallback for backward compatibility.

Actual Behavior

Only plugins declaring "oc-plugin": ["server"] in package.json are loaded. The entire ecosystem of existing plugins is broken.

Workaround

Downgrade to v1.3.7:

opencode upgrade v1.3.7
bunx oh-my-opencode-slim@latest install --reset --no-tui
After downgrade, all plugins load normally.
Environment
- macOS Apple Silicon
- OpenCode v1.3.8 (broken) / v1.3.7 (working)
- Plugin: oh-my-opencode-slim 0.9.0
Additional Context
The PluginModule type in @opencode-ai/plugin@1.3.8 now expects { server: Plugin } instead of a bare Plugin export. This appears to be introduced in v1.3.4 ("Add single target plugin entrypoints") but plugins in the ecosystem haven't adapted yet.

### Plugins

v1.3.8

### Steps to reproduce

Steps to Reproduce
Install v1.3.8 (opencode upgrade v1.3.8)

Observe: "No plugin targets found"
Expected Behavior
Plugins that export a valid Plugin function (the previous standard) should be loaded, or there should be a fallback for backward compatibility.

Actual Behavior
