Udit Akhouri releases **ADHD**, an open source (MIT) skill for "parallel divergent ideation" for coding agents: N **isolated** agent calls under deliberately distorted cognitive frames, then a separate critic that scores, clusters, **flags traps**, and deepens the survivors — an **architectural** fix (not a prompt) to LLM premature convergence.
**Boris Cherny** (Creator & Head of Claude Code @Anthropic) publishes a framework table on LinkedIn, **« Steps of AI Adoption »**, mapping an engineering team's adoption of agentic AI across **5 stages (0→4)**, each characterized by an **order of magnitude of agents driven** and a **transformation of the engineer's role**: **0 Gated** (0 agents, locked-down access), **1 Assisted** (~1 agent — "you + one agent", supervised pair programming), **2 Parallel** (~10 agents — **orchestrator**), **3 Supervised autonomy** (~100 agents — **manager of managers**, an org tree), **4 AI-native** (~1,000+ agents — **VP steering by intent**). The table crosses five columns: number of agents, *what it looks like*, *the bottleneck*, *the products that help*, *the guardrails*. **Central thesis**: consuming more tokens does not move you up a level — advancing to the next stage requires **identifying and breaking the next bottleneck** AND **building the next set of guardrails**. Concretely: giving Claude a trustworthy **self-verification loop** (tests + build + lint + e2e on a real environment), enabling **Auto mode** (avoiding blocking permission prompts), making **code review and security review the default**, adopting multi-agent interfaces (Agent view CLI, Desktop, iOS/Android apps, Tag), then `/loop`, `/batch`, `/goal`, **dynamic workflows** and **worktree isolation** for subagents. On steering: usage (dashboard) measures **activity, not return**; the right question is *"would we have spent engineering effort on this anyway? if so, how many manual engineer-hours would it have cost?"* — that's the ROI. The real payoff arrives when **fixing and maintaining happens in the background** and teams focus on *building*. Anthropic sits at **stage 3, heading toward 4**; Boris Cherny states he has personally reached **level 4**.

Article by **Paul Sawers** published on **The New Stack** on **June 16, 2026**, about the **suspension by Anthropic** — *"on the very day it was scheduled to go live"* — of the billing split meant to separate **Agent SDK** usage from Claude subscription limits. **Anthropic's cited message**: *"We're pausing the changes to Claude Agent SDK usage described below. For now, nothing has changed."* **The article's contribution is not the announcement but the surrounding context**, in three circles. **Circle 1 — Anthropic's week**: on June 9, the release of **Fable 5 and Mythos 5**, the first generally available Mythos-class models with hardened cybersecurity safeguards; a few days later, a **US government export control directive** forces Anthropic to **withdraw both models for all its customers worldwide**. The pricing suspension is read as *"a little good news"* in this context. **Circle 2 — collateral damage from the timing**: companies that had already passed the change on to their own customers find themselves caught out; **Conductor**, a multi-agent coding tool built on the Agent SDK, has to issue a denial (*"Anthropic has delayed the subscription updates to Claude plans"*). **Circle 3 — the underlying tension, which extends beyond Anthropic**: a quote from **Boris Cherny** (head of Claude Code) in April, during an earlier restriction, stating that subscriptions *"weren't built for the usage patterns of these third-party tools"* — an admission that **flat-rate plans and open-ended agentic usage don't mix**; **GitHub** settled the matter the same way, removing in June **Copilot**'s flat-rate *premium requests* model in favor of **token-based billing**, despite protests. Added to this, **the same week**, a **proposed class action** was filed in a California federal court, alleging that **Max** tiers fall well short of the usage multipliers advertised for intensive coding sessions. Anthropic does not say when a revised approach will arrive, only that it *"works to update the plan to better support how users build with Claude subscriptions."* **The author's final take**: between government pressure on Fable and Mythos, a planned **IPO**, and **rumored price cuts at OpenAI**, Anthropic is trying to **keep its developer base on its side** — and the suspension is, for now, a means to that end.

Synthesis by Addy Osmani (Google, Chrome/Cloud) of the emerging field of *harness engineering*: the equation `agent = model + harness`, the *ratchet* principle ("every mistake becomes a rule"), the HumanLayer "skill issue" reframe, Terminal Bench evidence (Top 30 → Top 5 from a harness change alone), the layered Claude Code architecture, Anthropic's "harnesses don't shrink, they move" vision, and Harness-as-a-Service (Claude Agent SDK, Codex SDK, OpenAI Agents SDK). Pivot article that consolidates Trivedy, HumanLayer, Anthropic, and Böckeler into a doctrine.
