Tools and packages I've published for the developer community.

~/ node

CLI · AI Agent Firewall

$

agent-blackbox

A local firewall for AI coding agents. Blocks API keys and .env values from leaking into prompts, enforces a budget kill-switch that halts runaway token spend before an overnight loop runs up a huge bill, and inspects MCP tool traffic for leaks — all while showing exactly where your tokens and dollars go. No account, no cloud.

Mobile App · Private Finance

$

jeb

An offline-first money tracker that keeps everything on-device in a local SQLite database and syncs privately through your own iCloud or Google Drive — no Jeb account, no backend, no analytics. Tracks income, expenses, accounts and wallets with recurring rules and receipts; long-running plans (assets, loans, zakat); monthly budgets with a spending-trend Insights screen; live multi-currency FX; biometric lock; and CSV/PDF export.

CLI · Pre-Release Quality Gate

$

flutter_release_checklist

A pluggable Dart CLI that runs a pre-release security and quality checklist on Flutter projects — ten independent checks covering debuggable manifests, hardcoded secrets, ProGuard config, and more, with a colorized pass/warn/fail summary and non-zero exit on failure.

Package · HTTP Inspection

$

flutter_netwatch

A production-grade HTTP inspection tool for Flutter apps. Captures network traffic via a floating bubble UI, with sensitive-data masking, cURL/Postman export, and security analysis. Integrates with Dio, http, and Chopper — and stays inactive in release builds.

$ flutter pub add flutter_netwatch
