[bug] `opencli antigravity serve` fails with ERR_MODULE_NOT_FOUND — dynamic import path off by one `..`

[LeoLin990405]

Repro

$ opencli antigravity serve --port 8082
Error [ERR_MODULE_NOT_FOUND]: Cannot find module
  '/Users/leo/.npm-global/lib/node_modules/@jackwener/opencli/dist/clis/antigravity/serve.js'
    at ModuleLoader.resolveSync (node:internal/modules/esm/loader:749:52)

• opencli v1.8.0 (npm @jackwener/opencli)
• macOS 26.4.0 (Darwin arm64)
• node v26.0.0

Root cause

dist/src/cli.js line 3056:

const { startServe } = await import('../clis/antigravity/serve.js');

cli.js lives at dist/src/cli.js. Relative '../clis/antigravity/serve.js' resolves to dist/clis/antigravity/serve.js, but the bundled source is at <package_root>/clis/antigravity/serve.js (one level up — not under dist/).

Verified the package layout in npm root -g:

@jackwener/opencli/
├── clis/antigravity/serve.js   ← actual location
├── dist/
│   └── src/cli.js              ← contains the broken `import('../clis/...')`
└── package.json

One-line fix

-        const { startServe } = await import('../clis/antigravity/serve.js');
+        const { startServe } = await import('../../clis/antigravity/serve.js');

(Or, if you prefer, use `url.fileURLToPath(import.meta.url)` + `path.resolve` for robustness.)

Local workaround (verified)

sed -i '' \"s|'../clis/antigravity/serve.js'|'../../clis/antigravity/serve.js'|g\" \\
  \$(npm root -g)/@jackwener/opencli/dist/src/cli.js

After patch:

• `opencli antigravity serve --port 8082` listens correctly
• `curl -X OPTIONS http://localhost:8082/v1/messages\` returns `HTTP 204`
• End-to-end Anthropic-API call to Antigravity works

Audit suggestion

Worth grepping the rest of `dist/src/cli.js` for other `import('../clis/...` dynamic imports that may have the same off-by-one issue. If only `antigravity/serve` is affected, single-line fix is enough.

Volunteer

Will follow this up with a PR (forking now).

Discovered while

Building a 5-surface bridge layer on top of opencli for orchestrating multi-agent code review pipelines from Claude Code. opencli's `antigravity serve` HTTP proxy is the cleanest path for synchronous push-and-wait IPC between Claude and Antigravity — losing it forces fallback to fragile DOM polling. Hence the 1-line fix matters disproportionately.
