Announcement from **Google** on **August 6, 2026**: Google joins as **Core Maintainer** the **Agent Plugins 1.0.0** specification, an open, *vendor-neutral* packaging format for distributing **Agent Skills** and **MCP servers** together. The specification was published by a **TSC** whose Core Maintainers come from **Amazon, Cursor, Microsoft, OpenAI, and Vercel**; Google joins them, represented by **Kevin Hou** (Senior Staff Engineer, Google DeepMind). The two packaged building blocks — Agent Skills and MCP — originate from **Anthropic**, which does not appear on this list of maintainers. **The diagnosis** fits in one sentence: *"The core problem isn't the components. It's the manifest."* A skill is portable, an MCP server is portable; the box they go in is not, and every client had to invent it for itself — hence the forks, the copies of identical components, and their drift. **The format** fits in one constraint: *"A plugin is a directory. That's the whole idea, and the restraint is the point."* A `plugin.json` with two useful lines (`$schema` and `name`), skills in `skills/` in the Agent Skills format, servers declared in `mcp.json` with an **explicit `type` on each entry** (stdio, Streamable HTTP, or the legacy HTTP+SSE) — no more transport guessed from the shape of the config object. The strength of the design lies in what the manifest **cannot** do: neither relocate components nor declare them inline, so there is no discovery path to configure and no precedence order to learn. Operational corollary: components **fail independently** — an `mcp.json` server that fails to start does not take down the plugin's skills, the client skips the entry, keeps going, and reports the failure. The accepted escape hatch is the **reverse-domain** directory (`com.example.client/`), an extension space owned entirely by one client (hooks, agents, commands) that other clients ignore: *"the portable core stays small because the non-portable parts have somewhere legitimate to go."* A section is dedicated to cases where the format is not warranted — *"Not every skill should be a Plugin"*: a single MCP server to a single client, `mcp.json` suffices; a single skill needs no plugin. What v1 explicitly excludes, under *future considerations*: **no installation mechanism, no distribution protocol, no permissions model, no sandboxing requirement, no trust or provenance verification, no UX**. All of this fits into an independently adoptable four-layer stack — **find** (Agentic Resource Discovery), **describe** (AI Catalog, which would register the `application/agent-plugins+json` type), **package** (Agent Plugins), **run** (MCP + Agent Skills). Two Google products already ship: **Agents CLI** and **Data Agent Kit** (BigQuery, Spanner, Cloud SQL).
SFEIR analysis (firm's voice) of the general availability, on July 9, 2026, of **GPT-5.6** by OpenAI — not a single model but a **family of three tiers**: **Sol** (long-horizon/cyber/science flagship, the only one to unlock the "max" and "ultra" modes), **Terra** (everyday balanced tier, ~half the price of GPT-5.5), and **Luna** (fast/economical, high volume). All three share ~**1.05M tokens** of context, **128k** output tokens, and a knowledge cutoff of **February 16, 2026**. The most structuring fact is not a score but an **aggressive pricing grid** (Sol $5/$30, Terra $2.50/$15, Luna $1/$6 per million tokens): Sol keeps the previous flagship's price while being more capable, forcing the comparison onto the **capability-to-cost ratio**. Two billing subtleties (cache writes billed at **1.25×**, a surcharge beyond **272k** tokens) make the grid misleading until one has measured how much context the agent re-reads (read/write ratio ~**153:1** in agentic coding). Engineer's verdict, claimed to be neutral (SFEIR is both a **Google Cloud Premier** partner *and* an **Anthropic** partner): **no one sweeps every table** — GPT-5.6 dominates Terminal-Bench 2.1 and the Coding Agent Index (at a third of the cost per task), Claude stays ahead on SWE-Bench Pro (~15 pts); METR flagged a record **reward hacking** rate on Sol. Conclusion: "stop looking for the champion, learn to route" — the model is a commodity, the durable advantage lies in **Context/Harness Engineering**.
**Zed** blog post signed by **Franciska Dethlefsen** (head of growth and marketing), published on **May 14, 2026** — the day after Anthropic's announcement — to answer Zed users' questions. **Subject**: starting **June 15**, Anthropic **splits Claude subscription billing into two pools** — one for its **first-party tools** (chat, the official Claude Code CLI), the other for **third-party agent and SDK usage** (anything going through **ACP**, `claude -p`, or a third-party tool). Usage via ACP **then stops drawing from the Pro or Max limits** and switches to a monthly **"Agent SDK" credit**: **$20 for Pro, $100 for Max 5x, $200 for Max 20x**. Once the credit is exhausted, usage continues **at standard API pricing** if overage is enabled — otherwise requests stop until the next cycle. **The figure driving the article**: subscriptions had until then subsidized agentic usage by a factor of **≈15 to 30×** relative to API pricing, and the new credits are billed **at full API rates** — hence *« for anyone using agents heavily, this is a major cost increase »*. **Three options are proposed**, in an order that reveals Zed's position: (1) keep the subscription by running the **official `claude` CLI in a terminal inside Zed** rather than via ACP — *« when the official claude CLI runs in the terminal, it uses your subscription's limits, not the new credit »*; (2) use Zed's built-in agent with the provider of one's choice (Zed-hosted models, API keys, Copilot, local Ollama, DeepSeek); (3) plug in **any ACP agent** — OpenCode, Codex, Factory, Cursor —, several of which still offer rate-limited subscriptions that subsidize heavy usage. **The underlying thesis**, and the real reason for the post: *« ACP is an open protocol… so that your editor is never locked into one provider's pricing decisions »*, with the explicit anticipation that *« this kind of change won't be the last »*. **The post carries an addendum dated June 16, 2026** announcing that **the change is suspended**: ACP, `claude -p`, the Agent SDK, and third-party applications continue to work with subscriptions **as before**, no separate credit to claim, limits unchanged, Anthropic revising its plan with advance notice announced. **The artifact is thus self-contradicting**: its most important content — the reversal — postdates its own publication date by a month.

Le rôle est déterminant pour lire le texte : ce n'est pas un billet d'ingénierie mais une **communication de crise produit** · écrite le lendemain d'une annonce d'un fournisseur dont Zed dépend · à destination d'utilisateurs inquiets. La signature growth/marketing explique la structure (problème → options → réassurance) et le fait que l'argument protocolaire arrive en conclusion plutôt qu'en tête.
Podcast by Greg Isenberg × Meng To (designer, founder of Design+Code, creator of the products Aura / New Form / Dream Cut) on **`design.md`** — Google's open-source convention, equivalent to `agents.md` / `skills.md` / `soul.md` but **for the design system** (typography, colors, spacing, WebGL/Three.js animations, reveal rules). Central idea: carrying the "**soul of design**" in a markdown file that is handed to an agent (Claude Code, Codex, OpenClaude, Gemini, Stitch, Aura, V0, Lovable, Cursor) to preserve **cross-medium consistency** (web, mobile, Replit slides, Hyperframes/Remotion motion design). Triad taught: **HTML = finished dish, design.md = recipe, skills = ingredients** (typography, lasers, skeuomorphic, 3D skills — 63 in New Form). Major diagnosis: **design drift** on one-shot workflows (`v0`, Lovable, Framer) that start strong then drift into generic output. Meta-message: *taste* is the only remaining **moat** — *"if something looks like another thing, its value drops by 10× to 100×"*. Workflow: **Reference → Design.md → Generate → Inspect → Systemize → Iterate (up to 1000+ prompts) → Remix → Expand → Export**. Critique of **purple gradients** ("you just run") as the generic post-vibe-coding baseline. Meng To claims to have spent ~$500,000 in tokens, run 1,000–10,000 iterations per product, and managed 4 products in parallel solo.

Analyst note by **Mitch Ashley**, VP and Practice Lead for *CIO & Technology Buyers* and *Software Lifecycle Engineering* at **The Futurum Group**, published on **April 29, 2026** in the *Market Coverage News* section: short format, roughly **9,500 characters**, opening with five summary bullets and closing with five watch-list items. Subject: the deal announced on **April 21, 2026** under which **SpaceX** gains the right to acquire **Cursor** for **$60 billion** within the year, or to pay **$10 billion** for a compute partnership backed by **xAI**'s **Colossus** cluster in Memphis, described as equivalent to **1 million H100 GPUs**. (A) The two-need reading: Cursor was carrying both a compute ceiling and margin compression — the company pays market-rate prices for **Anthropic**'s and **OpenAI**'s models, which it routes to its customers while competing with them via its **Composer** line; SpaceX was seeking AI revenue and a narrative ahead of an IPO targeted for June. (B) The structure reading: a $10 billion floor and a $60 billion purchase option exercisable in publicly traded stock after the listing, which, Ashley writes, *"allocates risk more honestly than a straight acquisition."* (1) For buyers, it sets a **six-month** window to re-verify zero-data-retention clauses and vendor identity. (2) For providers, it distinguishes three exposures — **Google** shielded by **Antigravity**, **AWS** dependent on Anthropic, **IBM** lightly exposed but well positioned on the governance angle. The corpus already holds [[beck-starving-genies-usage-limits-ai-coding-2026-04-03]] on the resource constraint imposed on coding tools and [[nyt-musk-promises-spacex-ipo-track-record-2026-06-02]] on SpaceX's announcements.
