….30 loader crashes on it
opencode's plugin loader treats any export whose value is a function as a
plugin factory and crashes the server at startup ('plugin config hook failed
(N.config)'). The plugin's named export runWithSpuriousRetry (added for the
retry unit guard) therefore broke opencode launch entirely: 'Unexpected server
error' before the first prompt.
Expose it as a property on a const object instead ('retry.runWithSpuriousRetry')
and point retry_test.ts at that. Reproduced standalone: opencode run fails to
boot with the function-valued export present, boots cleanly (\pong\) without
it; the retry guard still passes (ALL OK).

Problem
opencode (>= the 1.18 line, tested on
opencode-ai@1.18.30) fails to start when the code-preview plugin is installed:opencode rundies withUnexpected server error. Check server logs for details.and the server logs show:plugin config hook failed—undefined is not an object (evaluating 'N.config')Event listener failed—undefined is not an object (evaluating 'V.event')Root cause is the plugin module's named function export
runWithSpuriousRetry. opencode's plugin loader treats any export whose value is a function as a plugin factory. When it can't process it (it has noconfig/eventshape), it throws during startup — before the first prompt. Every other export form is fine (default export, named const with a scalar, named const whose value is an object).Reproduced standalone with minimal plugins against
opencode 1.18.30:opencode run pingexport async function f() {}(+/- default)export const f = async () => {}pongexport const retry = { run: ... }+ defaultpongFix
backends/opencode/index.ts— drop theexportkeyword fromrunWithSpuriousRetryand expose it as a property on a const object:export const retry = { runWithSpuriousRetry }. The plugin module now only has a default export (its hooks) plus the const, so the server boots.tests/backends/opencode/retry_test.ts— read the helper frommod.retry.runWithSpuriousRetryinstead ofmod.runWithSpuriousRetry.Behavior is unchanged: the hooks still call the same retry helper, and the unit guard still exercises it.
Verification
opencode run ping→pong(exit 0). Before the fix, the same setup →Unexpected server error(exit 1). Tested on Windows, opencode 1.18.30.tsx tests/backends/opencode/retry_test.ts→ all 5 checks pass,ALL OK.
