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.

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.

How OpenClaw remembers things, learns new skills, and runs tasks on autopilot. From Embeddings to Cron Jobs — explained for Python developers.

Claude Code creator Boris Cherny posted a 12-tweet thread breaking down why engineers love Claude Code: extreme customizability — hooks, plugins, LSPs, MCPs, skills, custom agents, output styles, 37 settings, 84 env vars, all committable to git for team sharing.

OpenAI's Responses API now uses 'Skills' via the shell tool: reusable instruction bundles loaded by models as needed. Simon Willison found inline base64 skills in JSON requests neatest. Skills fill the 'missing middle layer' between system prompts and tools, preventing bloat.
