The Agency language
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo concrete malicious install hook, stealth persistence, or unauthorized data exfiltration was found. Because the package is an agent-oriented language runtime with broad user-code execution and the supplied static analysis reported incomplete coverage, it should be warned on rather than marked clean.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the agency CLI or invokes its runtime/OAuth features.
Impact
Supplied program code can run with the invoking user's permissions; OAuth tokens may be stored for configured providers.
Mechanism
Compiles and runs supplied programs, with optional OAuth and local model serving.
AI rationale
No concrete malicious install hook, stealth persistence, or unauthorized data exfiltration was found. Because the package is an agent-oriented language runtime with broad user-code execution and the supplied static analysis reported incomplete coverage, it should be warned on rather than marked clean.

Decision evidence
public snapshotAI called this Suspicious at 72.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The package exposes a CLI that compiles and launches supplied Agency programs in a child Node process.
- Its runtime materializes compiled program code under the package directory before forking a subprocess.
- OAuth support can open a browser, accept a local callback, and exchange a user-configured authorization code for tokens.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The reviewed process launches use argument arrays and explicitly disable the shell where applicable.
- The OAuth flow restricts non-local authorization and token endpoints to HTTPS and validates callback state.
- The local model readiness request targets only 127.0.0.1.
