Foundation Engineering — In the Loop Era, the Scarcest Thing Is the Button the Dog Can't Press
Loop Engineering is the wrong name. The real work isn't the loop—it's the foundation nobody photographs: push 'what counts as correct' down to the cheapest enforcer, align granularity, lay a nine-layer sensor net, pay off comprehension debt. Execution went free; legislation got expensive.
Why Production Agents Converge on MCP — Anthropic's Breakdown of API vs CLI vs MCP
Anthropic's guide to connecting production agents to real systems. When agents move to the cloud, API / CLI / MCP all ship — only MCP compounds. Uses Cloudflare's MCP server (2 tools, ~2,500 endpoints, ~1K tokens) as the benchmark for remote-first design, intent-grouped tools, and production auth.
The Honest Multi-Agent Report, 10 Months Later — Cognition's Walden: Keep Writes Single-Threaded, Let Other Agents Pour In Intelligence
Cognition's Walden Yan returns after Don't Build Multi-Agents with three patterns that actually ship: Devin Review's clean-context loop, cross-frontier smart friends, and manager Devin. The common rule: writes stay single-threaded.
Skillify: Turn Every Agent Failure Into Something Structurally Impossible to Repeat — Garry Tan's 10-Step Checklist
Garry Tan's agent screwed up twice this week — both bugs had the same shape: deterministic work done in latent space. His fix is skillify: every failure becomes a SKILL.md + deterministic script + tests + evals + resolver trigger. Ten steps. The bug becomes structurally impossible to repeat.
