RLM-based CLI chat wrapper for Claude with external history context management

AI Security Review

scanned 3d ago · by lpm-firewall-ai

The manifest and inspected excerpts show expected setup, update, and gateway behavior, with no confirmed attack. Required runtime and account-action paths remain untraced, so the evidence is insufficient to mark the package clean or to assign a warning or block.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

The package's gateway or runtime APIs are invoked; the relevant callers and activation paths were not completely inspected.

Impact

The available source does not establish malicious impact; the incomplete runtime review prevents a clean conclusion.

Mechanism

The reviewed code generates MCP configuration and runs Claude locally. The remaining runtime and account-action paths need review to determine their full behavior.

AI rationale

Decision evidence

public snapshot

AI called this Manual Review at 62.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest defines build, prepublishOnly, and prepare scripts, but no preinstall, install, or postinstall hook.
Gateway setup is presented as an explicit setup command; the update function installs a specified version of this package when invoked.
The inspected runtime code generates MCP configuration and starts local Claude execution; automated agent turns are queued when a thread is busy.

Evidence against

The full runtime review remains unresolved: relevant account-action callers and required runtime locations were not all traced, so the inspected excerpts do not establish a clean verdict.
