@bongos/core@1.20.31

Cloud Bongos — the AI-first build platform core (GDS + platform surfaces + module system), installed as a versioned dependency (ADR 0108).

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The explicit setup command installs a first-party agent permission allowlist that includes consequential operations, leaving a concrete local agent capability risk. The package has no npm lifecycle trigger or verified credential-exfiltration behavior, so a warning is appropriate.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A user runs `bongos init` for an instance that has no `.claude/settings.json`.

Impact

A misdirected or unexpected local agent action could make changes through the approved commands under the user's account.

Mechanism

The materializer writes a permissions allowlist that includes state-changing Bongos commands and token-related commands.

AI rationale

Evidence

bin/bongos.jsscripts/gds/init.jsscripts/gds/claude-materialize.jspackage.json.claude/settings.json

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest exposes an explicit CLI and contains no npm lifecycle scripts.
The CLI offers `init` as an instance-scaffolding command, and `init` materializes Claude configuration in the project.
When no project settings file exists, the materializer writes a permissions allowlist that includes commands for claiming, shipping, releasing, reauthentication, token pasting, and API calls.
This creates a local agent capability risk: the approved commands can run without another per-command approval.
The flagged skill-lint locations read a tool event and lint the affected skill file; they do not perform account actions.

Evidence against

The settings change is tied to explicit project setup, not an npm install hook.
The generated starter contains permissions only, and the package source provides no evidence of credential transfer or stealthy execution.
