The Codex CLI config that ends the permission nagging — config.toml profiles, sandbox and approval modes, AGENTS.md, reasoning effort, MCP servers, and the codex exec setup for CI.

The OpenCode config that earns its keep — opencode.json layers, the build/plan agents, permissions, AGENTS.md, MCP, and the bring-your-own-model setup that survives a vendor pulling your access.

On June 7, 2026, X renamed the agent loop 'loop engineering' and called it the successor to harness engineering. We ran 47 Claude Code loops in a sandbox to test the claims. The naming churns; three of the technical findings are real and one is measurable to the cent.

Garry Tan's gstack passed 101,020 GitHub stars in ten weeks. Inside the repo: 33 slash commands, 7 standalone CLIs, 4 OpenClaw skills. Here is the full reference, every skill with three concrete examples, and the LOC controversy decoded.

The Developers playlist is Anthropic's public lecture series for builders. Read against Building Effective Agents, MCP, and Claude Code, the canon hangs together. Here is what it argues.

Two near-simultaneous coiners (Mitchell Hashimoto and Viv Trivedy), seven convergent voices, and twelve coding agents that all built the same primitives independently. A discipline crystallized in nine months — what it is, who built it, and what every shipping product now contains.

Mubbu's May 3 X long-form lays out a 5-agent stack for running founder personal brands in 45 minutes a week. The architecture is real. The proofs are gated. Here's the audit.

The Claude Code config Boris Cherny actually runs — settings.json layers, permissions, plan mode, memory, hooks, skills, subagents, MCPs, sandboxing, and the 5-worktree workflow.

Since Anthropic shipped the SKILL.md spec in September 2025, 480+ marketing-flavored skill repos have surfaced on GitHub. Four canon leaders, a bimodal quality distribution, and four conspicuous gaps.

Lieben's two May drops in 24 hours: the 19-API picture and the API-led GTM playbook underneath. What shipped, what's vapor, and the five-step migration that decides whether your skill survives team handoff.
