AI Coding Agents
Autonomous software agents (Claude Code, Stripe Minions, Gas Town Polecats) that read codebases, write code, run tests, and open pull requests with minimal human interaction during execution.
Skills
Markdown files that tell AI models how to perform specific tasks, optionally accompanied by extra documents and pre-written scripts. Skills extend what agents can do.
Backpressure
Automated feedback systems (type checkers, linters, test suites, build systems) that keep agents on track. Without backpressure, you review trivial mistakes. With it, agents self-correct.
Self-Improving Factory
A closed-loop system where agents monitor user feedback, analytics, A/B tests, error logs, and production data to populate the backlog without human curation.
Blueprint Architecture
Hybrid systems combining deterministic code nodes (run linters, push changes) with agentic subtasks (implement feature, fix CI). A pipeline with guardrails, not full autonomy.
The Factory Is the Product
The meta-insight that the factory itself compounds in value. Skills built, pipelines improved, and architectural decisions that make the codebase more agent-friendly all accumulate.
