Visual feedback as agent work packets. Stakeholders drop pins on your live app; your AI coding agent reads each pin (selector, screenshot, DOM, thread, acceptance criteria) via MCP and ships the fix.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has no automatic install lifecycle hook. Its sensitive operations are reachable through explicit commands and are consistent with its MCP feedback and cloud-sync functionality.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Explicit CLI subcommands or MCP feature use.
Impact
No install-time, covert credential-harvesting, or remote-code-execution behavior was confirmed.
Mechanism
Authenticated Pincushion sync, optional screenshot publishing, and opt-out telemetry.
AI rationale
The package has no automatic install lifecycle hook. Its sensitive operations are reachable through explicit commands and are consistent with its MCP feedback and cloud-sync functionality.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The explicit remote-url command places a stored license key into a URL and prints it, which can expose it to a terminal transcript.
- The explicit mobile-wall publish command uploads a user-selected screenshot and authenticates the request with the license key.
- The login command accepts a browser callback and writes its returned key to a user-level credential file.
- Telemetry is sent to PostHog, though the account identifier is hashed and opt-out controls are present.
- License helpers only label, mask, and gate license-key use; they contain no network or filesystem actions.
- The manifest defines no preinstall, install, or postinstall lifecycle hook.
Evidence against
- Network and file actions are tied to named CLI commands or MCP features, not package installation.
- Mobile-wall dispatches only after the user supplies its subcommand.
- The callback checks a random state before accepting and writing the login key.
- PostHog hashes non-anonymous identifiers before capture and respects opt-out environment variables.
- No self-dependency or install-time execution is declared.
