Addy Osmani outlines hooks to stop coding agents from weakening tests
Addy Osmani describes human-approved completion criteria and hooks that block test edits during implementation. Separate reviews check for weakened assertions, while recurring mistakes become shared hooks or tests.

Codex raises Sol’s default context to 500K tokens
GPT-6.1 Sol now defaults to 500K tokens in Codex and ChatGPT Work, up from 272K, to reduce compactions. OpenAI says subscriptions avoid long-context fees, and users can override the default up to 1M tokens.
