AI Security Review
scanned 2h ago · by lpm-firewall-aiLPM treats this as warn-only first-party agent extension lifecycle risk. A bundled VS Code/Trae extension automatically runs after that extension is installed, obtains an authorized Trae session, and writes its credentials to a KHY-readable file. The npm postinstall installs bundled backend dependencies but does not install or activate that extension.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User separately installs the bundled `khy-trae-bridge` VS Code extension; it activates on editor startup.
Impact
KHY backend processes can use copied Trae credentials for authenticated service access.
Mechanism
Authorized Trae-token bridge into KHY-readable shared extension storage.
Rationale
This is a real credential-bridging capability with automatic extension lifecycle behavior, but its activation requires separate extension installation and authorization and is package-aligned. No inspected source establishes unrelated credential exfiltration or malicious install-time mutation.

Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- `bundled/extensions/khy-trae-bridge/extension.js` auto-activates and requests the `icube.marscode` session.
- The extension writes access, refresh, and raw tokens to shared extension storage.
- Backend code reads the bridge token file and supports authenticated requests to Trae hosts.
- `scripts/postinstall.js` automatically invokes `scripts/devenv.js` during npm install.
- Postinstall runs `npm ci`/`npm install` inside the bundled backend when dependencies are absent.
Evidence against
- The npm postinstall does not install or activate the bundled VS Code extension.
- The extension requests authorization with `createIfNone: true` only after failed non-creating lookups.
- Token bridging is explicitly described by the shipped extension and backend as a KHY/Trae integration.
- No source inspected sends credentials to an unrelated endpoint or mutates foreign AI-agent configuration at install time.
- `index.js` only exports package and bundle paths.
