It extracts and stages an executable plus agent-related assets inside the installed package for later CLI execution. - **Trigger:** Installing the package runs npm postinstall; invoking \`onecode\` launches the staged binary. - **Impact:** A server or network attacker can supply a replacement executable that runs when the user invokes \`onecode\`. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-07-16T19:00:34.545Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unverified remote binary download, extraction, and launcher staging - **Rationale:** The package creates a real install-time remote payload staging path without transport or integrity verification. This is high-risk but source inspection does not prove the unavailable payload performs malicious actions. - **Files touched:** postinstall.mjs, platform-bootstrap.mjs, bin/onecode, .platform-bootstrap-work, node\_modules/onecode-\-\, bin/.onecode, .platform-version, .opencode, .oneskills - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`postinstall.mjs\` automatically invokes the bootstrap during npm postinstall., \`platform-bootstrap.mjs\` downloads a versioned tgz from \`https://218.90.133.98:4443/onecode\_tgz\`., The downloader disables TLS verification with \`rejectUnauthorized: false\` and has no signature or checksum validation., The postinstall path extracts the remote archive into \`node\_modules\` and marks its binary executable., It symlinks downloaded \`.opencode\` and \`.oneskills\` assets into the package root. - **Evidence against:** No source reads credentials, user home directories, SSH files, or environment secrets., The postinstall source does not execute the downloaded platform binary., All observed writes are under the installed package root and its \`node\_modules\`; no foreign user-level agent configuration is targeted., \`bin/onecode\` runs the staged binary only when the user invokes the CLI. ## Public findings ### 1.
