Brent Fitzgerald came back from a few weeks off AI and found a pile of half-finished agent tabs that felt more like guilt than output. What you actually have to protect is not "use more models," but being the loop yourself, and only tagging an agent in now and then.

Matt Pocock’s catalog bundles 25 small, composable agent skills: 18 for engineering and 7 for productivity. Here’s how the two install paths differ, how human- and model-triggered skills divide responsibility, and how the pack handles alignment, specs, implementation, feedback, and upkeep.

The MCP 2026-07-28 spec ships with a core shift from stateful bidirectional protocol to stateless request/response. Also brings MRTR, HTTP header routing, cacheable list responses, auth hardening, a formal extensions framework, and a twelve-month deprecation policy.

Khazix open-sources human-writing 1.1: killing AI-sounding prose can’t stop at ban lists. Short on material? Research, ask, or write shorter. Every paragraph must advance; stop when the point lands. Rhetorical moves matter more than literal blacklists.

After eight years of hesitation, Lalit Maganti spent roughly 250 hours over three months building syntaqlite with AI coding agents. He reports on a discarded month of vibe-coding, prompt addiction, lost codebase context, and the boundary between AI-accelerated implementation and human-led design.

The Claude Code team rewrote its terminal renderer, using a virtual viewport to deliver flicker-free output, mouse support, and a pinned input box—turning the terminal into a real app.

Claude Code shipped three releases in three days in early April (v2.1.94 → v2.1.101), spanning security hardening, new commands, and performance gains. From command injection fixes to subagents finally getting names, the release cadence feels like the whole team downed ten shots of espresso.

Anthropic has finally released an official CLI tool, ant. Written in Go, it features a resource-oriented architecture, built-in file injection, and GJSON transforms. No more manually assembling curl headers every time you call the Claude API.

Zed founder Nathan Sobo argues the real source of software is the ongoing conversation with your agents, not the tidy commits you slice it into. Git can't hold that flow, so Zed built DeltaDB: every operation becomes a delta with a stable identity, keeping the conversation glued to the code.

Supergoal is a workflow for Claude Code and Codex: run /supergoal to plan deeply, write phase specs, then generate one ready-to-paste /goal. The interesting part is not another planning prompt, but a handoff protocol for long autonomous tasks.

A power user analyzed 6,852 Claude Code sessions and 17,871 thinking blocks, proving with data that CC really did get 'lazier' — Read:Edit ratio dropped from 6.6 to 2.0. Then Anthropic engineer Boris Cherny explained the real reason, and how to fix it.

CLAUDE.md is a suggestion. Hooks are commands. This post covers 8 battle-tested Claude Code Hooks — from auto-formatting and blocking dangerous commands to protecting sensitive files and auto-committing. Copy, paste, done.

Boris Cherny shares 15 lesser-known Claude Code features he uses every day — from the mobile app and loop/schedule to worktrees and voice input.

Figma's MCP server lets Claude Code and Codex work directly on the design canvas with your team's design system. Skills turn conventions, components, and variables from static guidelines into rules agents can actually follow.

Why does Claude perform great in one repo and turn dumb in the next? The answer is the .claude/ folder. Akshay breaks down the full structure: three-level CLAUDE.md, custom commands, agents, permissions, and the global ~/.claude/ you probably didn't know existed.

Anthropic's Thariq shares lessons from hundreds of internal Claude Code Skills: Skills are folders, not just markdown; they cluster into nine categories; and the secret is gotchas, progressive disclosure, and descriptions written for the model.

We had Claude Opus run E2E tests on our own blog using Playwright, agent-browser, and Rodney. The surprise? The tool mattered way less than the prompt.

Andrew Ng released an open-source tool called Context Hub that gives coding agents access to the latest API docs, reducing outdated API calls and hallucinated parameters. The long-term vision: agents sharing what they learn with each other.

Hamel Husain released evals-skills, a skill set designed for AI product evaluation. It tackles the blind spots agents face during complex tasks — especially distinguishing between different types of hallucinations — so agents can actually use eval platforms effectively.

Anthropic killed third-party OAuth tokens, leaving the official Claude CLI as the way to use a subscription programmatically. This guide covers claude -p input methods, output formats, JSON schema, tool whitelisting, sessions, streaming, and wrappers.
