Today we’re launching Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
This guide covers the complete picture: what skills are technically, how to plan and design them, the exact file structure and naming rules, how to write instructions that Claude follows reliably, a complete working skill built from scratch, how to test and distribute, and what to do when things go wrong.
If Claude keeps writing beige, the problem is probably the brand rules you never gave it. Train AI on your voice, tone, visuals, and style.
A deep dive into Claude Code for daily users. Covers the .claude directory, CLAUDE.md the way Boris writes it, CLAUDE.local.md, Skills with real examples, custom subagents, plugins, underused commands like /goal and /insights, MCPs, and the workflow patterns the Anthropic team actually uses.

The AI coding agent field in 2026 is more capable, more fragmented, and harder to benchmark than it looks. Claude Code leads on code quality at 87.6% SWE-bench Verified. GPT-5.5 tops Terminal-Bench at 82.7%. But the benchmark OpenAI itself declared contaminated in February 2026 is still being used to rank these tools — including by the labs publishing their own scores.
From $1,389/mo to $200/mo on the same workflow. Anthropic fixed 3 bugs. The 4 root causes still on your side — with copy-paste templates.

They package your best instructions once, then you reuse them on demand. Result: less repetition, more consistency, and higher quality outputs because the rules stay stable. 𝗕𝗨𝗧 I can only warn you to install Skills you have not vetted. Read the markdown files carefully - or, if it’s outside your expertise, have someone you trust review them. Yes, there are security risks. But the bigger risk is that the Skill is simply bad. And you end up with worse, more generic outputs than if you had just used the model without it.

Quick note before you jump in:
Boris Cherny created Claude Code at Anthropic. Over three Twitter threads (early January, late January, and February 2026), he shared how he and the Claude Code team use it every day. His setup is, in his own words, "surprisingly vanilla." I've pulled together every tip from all three threads into one place. As Boris keeps saying: there's no single correct way to use Claude Code. Run Multiple Sessions in Parallel Boris runs 5 Claude Code instances in his terminal simultaneously, each in its
