   Anthropic’s reported Claude Self-Assessment mechanism

   AIbase AI新闻 reports that Anthropic introduced a post-response “Self-Assessment” safety mechanism for Claude Fable5 and later versions, reusing the model’s existing context and KV cache to review completed conversations. The report says it detected 78% of violations flagged by a heavier classifier, detected 94% of high-risk misuse, and kept the false-positive rate near 1%, while accounting for less than 2% of inference compute. It also describes separate, unattributed tests alleging stronger intent understanding and complex-task performance from a model called Fable5.5, but provides no reproducible methodology or original Anthropic publication.

   A Developer’s Guide to Pruning Codex Skills for Stronger Models

   In a Juejin commentary, the author argues that GPT-5.6, K3 and Claude Fable5 can handle many basic development steps that older Skills packages explicitly encoded. Using Codex as the main example, the author recommends retaining only Skills that add scripts, templates, specialist knowledge, personal preferences or reusable checks, while placing routine project rules in AGENTS.md and mechanical safeguards in Hooks, CI, linters or tests.
