PDT

Product Dev Tools for governed agentic systems. We’re building Geminy Cricket — the supervision layer for AI-driven software development — and Rubot — a Rails-based Agentic Internal Tools Framework for building AI-assisted operational software with workflow state, approvals, and human oversight.

Early design partners welcome. If you’re supervising AI development or building AI-assisted internal workflows, PDT is where we’re building the tooling.

What we build

Geminy Cricket

A local-first supervisor for AI-led development: it observes work across sessions, compresses failures into actionable signals, and keeps progress cumulative instead of fragile.

State machine orchestration Surgical failure “chirps” Semantic memory Checkpoints / rewind

Rubot

A Rails-based framework for agentic internal tools: it helps teams build AI-assisted backoffice software with tool calling, workflow state, operator-facing interfaces, approvals, and observability.

Agentic internal workflows Human-in-the-loop approvals Rails-native patterns Traces, state, and reviewability

Why it matters

Models can generate output, but production systems need supervision, structure, and control. PDT is focused on the layers that make agentic software usable in real environments.

How we engage

Limited, product-led engagements to deploy and harden PDT tools in real environments, so both products improve through real use.
