Claude Code 2.1.288 ships a built-in mod called "You should know" — a side agent that watches your main session and speaks up when it notices something you or Claude might miss. It's opt-in, requires telemetry, and represents a specific bet on how to surface the class of problems that slip through when you're not watching the terminal.
Read more →Claude Code 2.1.287 ships mods: in-process TypeScript modules that can intercept, rewrite, and answer agent events before they reach the model. Unlike shell-script hooks, mods run inside the session, keep persistent state, and carry a rich sandbox API covering UI, tool routing, secret redaction, and custom slash commands. OpenAI Codex has had lifecycle hooks for a while — the two approaches reveal different theories about where agent customization should live.
Read more →Meta's new terminal coding agent reads CLAUDE.md and .codex/ skills as project context when its own AGENTS.md file doesn't exist. Any content in those files — internal URLs, API endpoint docs, project constraints — goes to Meta's servers on every call, and to Meta's training data if you're on the contributor tier.
Read more →A developer reverse-engineered Claude Code's client JavaScript and found it silently substitutes Unicode apostrophes in system prompts to fingerprint requests routed through custom API base URLs — encoding domain-list hits and timezone signals in characters visually indistinguishable from ordinary text. The finding raises the usual trust question: should a developer tool that runs in your terminal quietly rewrite what it sends?
Read more →Stanford CS336 shipped a CLAUDE.md file in its assignment repositories that instructs coding agents to act as Socratic tutors rather than solution generators. It is a small thing technically and a significant thing conceptually: domain-specific behavior specification embedded directly in the project.
Read more →Apple Support app v5.13 accidentally shipped two CLAUDE.md instruction files in the app bundle, exposing internal architecture context including a shared UI library called SAComponents and a chat module with three participant roles. Apple pushed v5.13.1 hours later to remove them, but not before the contents circulated.

Two days later, Anthropic briefly moved Claude Code from its $20 Pro plan to its $100 Max plan before reversing under backlash. Both events reflect the same structural problem: per-seat flat-rate billing doesn't work when a single user session can run for hours.
Read more →Anthropic shipped Claude Code Routines in research preview: saved Claude Code configurations that run autonomously on Anthropic-managed cloud infrastructure on a schedule, triggered by an API call, or fired by GitHub events. The pieces have been building toward this — long-horizon sessions, Managed Agents, the advisor tool — and cloud-scheduled unattended execution is the natural next step.
Read more →Anthropic accidentally shipped source maps in their Claude Code npm package, exposing the full client-side source. The analysis that followed is worth reading not for the drama of a leak but for what the code reveals about the product's actual architecture: anti-distillation mechanisms, an "undercover mode" for employee contributions, and an unreleased background agent called KAIROS.
