Agent Harnesses & Governance

Self-Improving Agents & Harness Architecture

  • Karpathy, Autoresearch — Constrained agent loop: one file editable, one metric, fixed time budget, keep/revert via git. The harness design is the real work — the scaffolding matters more than the agent's raw capability.
  • Yegge, "Zero Framework Cognition" — Application code as a thin deterministic shell around AI reasoning. All judgment to the model, all plumbing to the harness.
  • Yegge, "Vibe Maintainer" — PR governance as agent governance at scale. The decision tree for what to merge, fix-merge, cherry-pick, reimplement, or reject — and why "request changes" is the last resort, not the first.
  • DGM-H / Hyperagents (Meta) — Self-referential agents where task agent and meta agent share a single editable program. The critical constraint: the agent cannot alter the outer evaluation process.
  • Darwin Gödel Machine — The predecessor. Open-ended self-improvement in coding via evolutionary archive of agent variants.
  • silly.business, "We Should Revisit Literate Programming in the Agent Era" — Agents eliminate the extra labor that killed literate programming. Prose-first organization as a constraint on agent output quality.

Cognitive Frameworks & Benchmarking

Filesystems, Environment & Agent Infrastructure

Lisp & Mezzano

  • Mezzano — A tour de force of programming. An entire operating system written in Common Lisp by froggey. Image-based, everything from scheduler to GUI compositor is live-redefinable CL. Runs a SWANK server at boot.
  • SLIME — Superior Lisp Interaction Mode for Emacs. The standard development interface for Common Lisp. Has a Mezzano-specific backend contributed upstream.
  • swank-client (npm) — JavaScript SWANK client library. Handles the wire protocol — hex-length framing, emacs-rex message construction, response parsing. The bridge piece for connecting non-Emacs tooling to any SWANK server.
  • agent-shell — Emacs package for running AI agents inside Emacs. The interactive path for watching an agent work through SLIME's existing SWANK connection.
  • Common Lisp Cookbook — Maintained by vindarel. The most-referenced beginner resource for CL.
  • Practical Common Lisp — Peter Seibel. The standard introduction.

Tools & Stack

  • chezmoi — Dotfile manager. Copy-based (not symlinks), with templating, 1Password integration, and machine-specific conditionals. Drift detection by default.
  • Ghostty — Terminal emulator. Native splits and tabs, macOS-native clipboard and mouse integration. No need for tmux locally.
  • mise — Runtime version manager. Replaces asdf, nvm, pyenv, rbenv with a single tool. Respects XDG paths.
  • fish — Primary shell. Sane defaults, no POSIX baggage, XDG-native.
  • AeroSpace — Tiling window manager for macOS. i3-like keybindings.
  • Omachy (site) — Go-based macOS config tool packaging AeroSpace, Ghostty, SketchyBar, JankyBorders, and Neovim into a single installable. Useful reference for SketchyBar and JankyBorders config.
  • 1Password CLI — SSH agent, commit signing, secrets in shell config via op:// references. The trust anchor for the credential chain.
