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
Ten months after writing Don't Build Multi-Agents, Cognition's Walden Yan returns with three patterns that actually ship: Devin Review's clean-context loop (2 bugs per PR, ~58% severe), cross-frontier smart friends, and manager Devin's map-reduce-and-manage. One principle runs through all three — writes stay single-threaded; other agents contribute intelligence, not actions.
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.
