We've retired our knowledge Skills. The auto-managed π™°π™Άπ™΄π™½πšƒπš‚.πš–πš teaches agents the framework's APIs now. We have new Skills that drive multi-step workflows instead. For example, πš—πšŽπš‘πš-𝚍𝚎𝚟-πš•πš˜πš˜πš™ verifies each change in a real browser via πšŠπšπšŽπš—πš-πš‹πš›πš˜πš πšœπšŽπš›.

The πš—πšŽπš‘πš-πšŒπšŠπšŒπš‘πšŽ-πšŒπš˜πš–πš™πš˜πš—πšŽπš—πšπšœ-πšŠπšπš˜πš™πšπš’πš˜πš— Skill migrates your app to Cache Components, feature by feature. It reads the Instant Insights, applies the fixes, and verifies each route with πš—πšŽπš‘πš-𝚍𝚎𝚟-πš•πš˜πš˜πš™, checking in so you stay in control.

The πš—πšŽπš‘πš-πšŒπšŠπšŒπš‘πšŽ-πšŒπš˜πš–πš™πš˜πš—πšŽπš—πšπšœ-πš˜πš™πšπš’πš–πš’πš£πšŽπš› Skill grows a route's shell so more of the page is ready before the request lands. It builds on πš—πšŽπš‘πš-𝚍𝚎𝚟-πš•πš˜πš˜πš™, screenshotting each change and rolling back anything that didn't help.

Each fix on an Instant Insight comes with a prompt your agent can run end to end. It walks the agent through the whole flow: read the docs page for the patterns and trade-offs, apply the fix, then verify it in the browser with πš—πšŽπš‘πš-𝚍𝚎𝚟-πš•πš˜πš˜πš™.

Frameworks are widening their doors to accommodate us. From inside, the files we generate feel less like architecture and more like high-velocity silt settling on a riverbed.

Next.js con AGENTS.md auto-gestionado formaliza lo que ya ocurre en equipos con Claude Code: la documentaciΓ³n de contexto para agentes se vuelve el artefacto mΓ‘s crΓ­tico del repo. La pregunta real es si el framework debe dictar ese contrato o si debe ser agnΓ³stico al agente.
