AI Security Review

Source establishes a persistent, first-party AI-agent extension and git-hook data path, so it warrants a warning. It is not malicious under the stated boundary because postinstall is display-only and no covert or foreign control-surface mutation occurs during installation.

Static reason

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

Trigger

Running the setup/autopilot or ambient configuration commands; later Claude events and git commits.

Impact

Project prompts, hook events, and commit metadata may be sent to Cachly under the configured credential.

Mechanism

first-party MCP configuration and persistent agent/git hooks

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

Explicit setup installs a git post-commit hook that invokes the package via npx.
Generated Claude hooks execute on session/prompt/tool/stop events and pass hook input to the package.
Telemetry sends the active JWT to api.cachly.dev unless opted out.
Postinstall only prints setup instructions; it performs no mutation.

Evidence against

No lifecycle script writes files or executes network requests.
Network targets are Cachly service endpoints, npm registry, and optional user-configured Telegram.
No hidden payload download, eval, or arbitrary command execution found.
