## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall fetches an externally hosted native archive with certificate verification disabled, extracts it, and makes its binary available to the package launcher. It also links downloaded .opencode and .oneskills assets into this package's root.

- **Trigger:** npm postinstall; downloaded binary runs when the user invokes onecode.

- **Impact:** A network or endpoint attacker can substitute the native payload later executed by the CLI and supply linked agent assets.

- **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode

- **Review source:** ai\_review

- **Reviewed:** 2026-08-17T08:13:14.792Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** unverified remote native payload bootstrap with package-root agent asset symlinks

- **Rationale:** This is a concrete unverified remote executable delivery chain and a package-root agent asset setup, but inspected source does not establish malicious payload behavior, exfiltration, or broad foreign agent-control mutation. It should be warned as a staged payload carrier rather than blocked on static source alone.

- **Files touched:** .platform-bootstrap-work, node\_modules/onecode-\<platform\>-\<arch\>, bin/.onecode, .platform-version, .opencode, .oneskills

- **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 97.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** postinstall invokes a platform bootstrap., Bootstrap downloads a versioned native archive from a fixed IP endpoint with TLS verification disabled., Downloaded archive is extracted and its executable is installed without checksum or signature verification., Postinstall replaces package-root .opencode and .oneskills paths with symlinks from the downloaded payload.

- **Evidence against:** Inspected JavaScript contains no credential harvesting or data-exfiltration logic., The launcher starts the downloaded binary only when the user invokes the onecode command; no source-level immediate execution occurs during postinstall.

function platformTgzUrl(version) {
  const base = (process.env.ONECODE_TGZ_DOWNLOAD_BASE || DEFAULT_TGZ_BASE).replace(/\/$/, "")
  const dir = encodeURIComponent(`onecode-${version}`)
  const file = encodeURIComponent(`onecode-linux-x64-${version}.tgz`)
  return `${base}/${dir}/${file}`
}

function downloadFile(url, dest) {
  return new Promise((resolve, reject) => {
    const file = fs.createWriteStream(dest)
    const req = https.get(url, { rejectUnauthorized: false }, (res) => {
