Context Engineering

Keep agent context small and useful: second-brain skills, a durable state bus for multi-agent pipelines, and an expert prompt builder.

Keep agent context small and useful: second-brain skills, a durable state bus for multi-agent pipelines, and an expert prompt builder.

What is inside

  • Build Brain (skill). Turn a skill or a pile of notes into an AI-optimized second brain: a lean map, small tagged references and JSON navigation, plus a before and after token report.
  • Prompt Expert (skill). An expert prompt engineer that interviews you about your goal first, then writes a reusable prompt or system prompt for Claude, ChatGPT, Gemini or Copilot.
  • Pipeline State (skill). A small file-backed handoff bus for multi-agent runs: each phase records its outputs and evidence paths, so later phases look them up instead of re-pasting them. Survives context compression.
