AI Security Review
scanned 10d ago · by lpm-firewall-aiThe install hook only displays instructions. The credential telemetry and commit-learning hook are package-aligned service behavior, with the persistent setup effects activated by an explicit CLI command, so the inspected source does not establish malicious behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Package installation runs a postinstall message; editor configuration and the Git hook are installed when a user runs setup or autopilot.
Impact
The inspected behavior supports the package’s Cachly service and learning features; no unrelated recipient, unconsented install-time mutation, or concrete malicious action was found.
Mechanism
The explicit setup flow writes Cachly editor integrations and a Git hook that forwards commit metadata to the Cachly API. Runtime telemetry also sends event data to that API.
AI rationale
The install hook only displays instructions. The credential telemetry and commit-learning hook are package-aligned service behavior, with the persistent setup effects activated by an explicit CLI command, so the inspected source does not establish malicious behavior.

Decision evidence
public snapshotAI called this Clean at 83.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook prints setup instructions; it does not itself configure editors or install the Git hook.
- The runtime defaults to the package’s Cachly API host, and its shared request helper sends the API token to that service.
- Credential helpers read tokens from local environment variables or this server’s local configuration; the inspected callers use the Cachly service.
- Editor and Git-hook setup is activated by explicit setup or autopilot commands, and the CLI reports that the Git hook will learn from commits.
- The Git hook submits commit messages, hashes, and changed file names through the package’s own cls-ingest command.
- The inspected agent integration files read local configuration or define Cachly-owned hooks; their installation belongs to the explicit setup flow.
Evidence against
- Runtime telemetry includes the API token in its event body, and some error telemetry sends it as an authorization header.
- After explicit setup, the persistent Git hook sends commit metadata to the Cachly service on each commit.
