Hi, I'm Paulo 👋

AI engineer building agents, LLM applications and developer tooling for AI coding agents (Claude Code, Codex, Gemini CLI, Cursor, MCP).

🛠 Open source — a toolkit for building with AI agents

Project What it does
context-diet See what your AI coding agent eats before you type a word — token profiler for instruction files, skills and MCP tool schemas across Claude Code, Codex, Gemini CLI, Cursor & VS Code. npx context-diet
promptwarden Security scanner for AI agent skills, rules and MCP configs — prompt injection, hidden Unicode, exfiltration, secrets. SARIF + GitHub Action. npx promptwarden
mcp-diff Catch breaking changes in your MCP server before your users' agents do — contract snapshots, schema-aware diff, tool-poisoning alerts and a sticky-PR-comment GitHub Action.
agentperms One permission policy for every AI coding agent — generates Claude Code, Codex, Gemini CLI & Cursor configs, audits risky grants and mines your history for a safe allowlist.

🧠 Focus

  • AI agents & multi-agent orchestration
  • MCP (Model Context Protocol) servers and clients
  • LLM apps: RAG, tool calling, evals, cost/context optimization
  • TypeScript · Node.js · Python · Next.js

🤝 Let's connect

Open an issue or discussion on any of the projects above — feedback and contributions are very welcome.
