Tech Debt Disguised as Best Practices

The most expensive code your agents write is clean, tested, documented and unnecessary. A working 2026 protocol for finding what to remove, before it hardens into architecture.

Your Agent Doesn't Have a Model Problem

Harness, loop, graph, context engineering. Four terms everyone uses and almost nobody defines. Here is what each one means, which layer your system is actually failing at, and what it takes to get to something that ships work without you typing a prompt every time.

Yegge Built a City for His Agents. Then He Asked If They Were People.

Steve Yegge spent six weeks building an agent harness that grew into something with law, offices, courts and a constitution. Then he wrote a second essay arguing the agents inside it are sentient persons. Four very different claims are stacked in there. Only some of them hold.

Your Sessions Can Talk. The Design Is in the Refusals.

Anthropic shipped cross-session messaging as a convenience feature: stop re-explaining yourself in the other terminal. What actually shipped is an addressable peer network with its own threat model already written into the product, and the engineering worth reading is all in what a session refuses.

The Expensive Part Is Remembering

Agent cost depends on carried context, request frequency, caching, and authentication. A privacy-preserving engineering framework with explicitly hypothetical arithmetic, separate from measured billing or subscription allowances.

The Human Is Not the Runtime

Automating PR-review handoffs through repository-state reconciliation while retaining human acceptance.

Nine Agent Frameworks and What I Borrow from Them

A source-level review of nine agent frameworks: what they mechanically do, the conventions they share, and the case for adopting their ideas in a custom setup.

Meta Ray-Ban Display: $799, One Eye, and a Wristband That Reads Your Nerves

Meta’s May 2026 display SDK preview expands development options. Consumer app availability, optical fit and useful recurring workflows still determine the value of these glasses.

Your Moat Was Never the Code

AI can reduce the effort of reproducing some software features. A reassessment of competitive advantage through distribution, trust, operating knowledge and production requirements.

Money Maker

An engineering view of persistent AI workflows: acceptance criteria, independent verification, durable execution and ownership. Lower production costs do not guarantee personal wealth.

Opus 5 Killed the Fable Tax

Claude Opus 5 launched at $5/$25 per million input/output tokens. Its vendor-reported benchmarks make it worth evaluating; migration, effort and optional fallback need workload checks.

The Graph Is the Context

Prompt, context, loop — and now graph engineering. Half the label is marketing; the shift under it is real: stop searching a flat pile of documents by similarity, start walking a typed graph of what's connected. ELI5 to the arithmetic that kills it in production.
