mixdog@0.9.19

Standalone mixdog coding-agent CLI/TUI workspace.

AI Security Review

scanned 2d ago · by lpm-firewall-ai

No confirmed malicious attack surface found. The package is a user-invoked coding-agent CLI with expected network, credential storage, child-process, plugin, and local runtime-management capabilities.

Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
user runs mixdog CLI or configures runtime/channel features
Impact
No install-time execution, exfiltration, persistence, destructive behavior, or foreign AI-agent control-surface mutation confirmed.
Mechanism
benign agent CLI runtime operations
Rationale
Scanner hits map to expected, user-invoked coding-agent functionality: provider/channel networking, local child processes, secure config/keychain storage, plugin admin, and verified runtime downloads. There are no lifecycle hooks or source evidence of credential harvesting, exfiltration, stealth persistence, or unconsented mutation of a broad foreign AI-agent control surface.

Decision evidence

public snapshot
AI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for block
    Evidence against
    • package.json defines bin src/cli.mjs and no preinstall/install/postinstall hooks.
    • src/cli.mjs and src/app.mjs only start the CLI/TUI or explicit headless role paths.
    • src/runtime/memory/lib/runtime-fetcher.mjs downloads package-aligned GitHub runtime assets, verifies SHA-256, and validates tar paths before extraction.
    • src/runtime/channels/lib/voice-runtime-fetcher.mjs uses bundled manifests with SHA-256 for whisper/ffmpeg/model downloads.
    • src/runtime/channels/lib/whisper-server.mjs spawns a local managed whisper server only at runtime and fails closed on non-owned port/process.
    • src/runtime/channels/lib/format.mjs contains an intentional zero-width escape inside code-fence formatting strings, not hidden control-flow logic.
