The solution might be cancelling my AI subscription
Simon Willison's Weblog14 days agoCommentarySimon Willison relates to David Wilson's reflection on launching more than 16 projects with AI tooling. A request for a quick Claude script can expand into an hour-long project without solving the original problem. Coding agents may produce tested, documented solutions rapidly, but people can maintain only so many projects. The critical skill may be discipline: deciding which ideas deserve continued attention.
Claude Code and Codex Can Have Real-Time Conversation via Git
Hacker News (AI keywords)14 days agoNew ToolThe article introduces Agent Radio, a messaging feature in h5i 0.1.5 for coding agents such as Claude Code and Codex. Instead of relying on an external server, it stores JSONL messages in a Git ref and syncs them through normal push and pull flows. The post includes setup commands, live message watching, PR summary posting, and a short explanation of the i5h protocol.
How we contain Claude across products
Simon Willison's Weblog15 days agoCommentaryAnthropic explains how process sandboxes, VMs, filesystem boundaries, and egress controls limit what Claude agents can access. Claude.ai uses gVisor; local Claude Code uses Seatbelt on macOS and Bubblewrap on Linux; Cowork runs in a full VM. Simon Willison highlights the documentation quality, notes a previously missed file-exfiltration path, and plans to revisit Anthropic's open-source srt tool.
Running Python ASGI Apps in the Browser via Pyodide + a Service Worker
Simon Willison's Weblog15 days agoTutorialSimon Willison demonstrates an experiment for running Python ASGI apps entirely in the browser using Pyodide and a Service Worker. The approach addresses a Datasette Lite limitation: HTML returned through intercepted navigation did not execute script tags, breaking features and plugins. Claude Opus 4.8, used through Claude Code for web, helped explore the implementation. Basic ASGI and Datasette 1.0a31 demos are available.
I Am Retiring from Tech to Live Offline
Simon Willison's Weblog15 days agoEthicsSimon Willison highlights Chad Whitacre’s decision to leave tech and Open Source, framed not as a forum threat but as concrete action. Whitacre describes wanting to become “AI Amish” or “Internet Amish,” moving toward an offline, analog life closer to 1980 than 1780. A previous post about using Claude Code with Opus 4.5 shows how agentic AI felt intoxicating and unsettling enough to push him away from technological accelerationism.

Hacker News (AI keywords)15 days agoCommentaryThe source is a Hacker News AI-keyword item linking to a Mastodon post titled “Rsync 3.4.3 has hundreds of Claude commits.” No original body text is available, so the only reliable claim is that many commits in Rsync 3.4.3 are described as Claude-related. The exact meaning, review process, quality impact, and author’s stance cannot be confirmed from the title alone.
MCP is dead?
Hacker News (AI keywords)16 days agoOpinionQuandri measured MCP tool schemas in its Claude Code setup and found significant context overhead across Linear, Notion, Slack, and Postgres. The post argues MCP can be slower, less reliable, and harder to debug than direct CLI/API usage. It recommends CLI-first workflows and on-demand Skills, while noting MCP still fits services without CLIs, non-developer users, bidirectional communication, and guarded production database access.
CAPTCHAs can still detect AI agents★ 72
Hacker News (AI keywords)16 days agoPaperRoundtable argues that CAPTCHA image recognition is largely solved, but process-level behavior still separates humans from AI agents. Their CogCAPTCHA30 benchmark combines CAPTCHA with cognitive psychology tasks to test not only outputs, but how answers are produced. Results suggest frontier models like Claude, GPT, and Gemini are not necessarily more humanlike than smaller or cognition-trained models.

Claude Opus 4.8: "a modest but tangible improvement"
Simon Willison's Weblog17 days agoReleaseAnthropic shipped Claude Opus 4.8, and Simon Willison highlights the unusually restrained release language: a “modest but tangible improvement.” The model keeps most Opus 4.7 pricing and specs, while evaluations suggest it is more likely to flag uncertainty and less likely to ignore flaws in code it wrote. Developer-relevant changes include mid-conversation system messages and a lower prompt-cache minimum of 1,024 tokens.

Trump loses more control over AI regulation as Illinois passes landmark law★ 74
Ars Technica AI17 days agoRegulationIllinois lawmakers passed a landmark AI accountability bill requiring major frontier AI developers to publish safety frameworks, assess catastrophic risks, report incidents, and undergo third-party audits. OpenAI and Anthropic supported the measure, while industry groups warned that state-level rules could impose subjective compliance duties without national standards. The bill signals that states are continuing to fill the federal AI regulation gap despite Trump’s efforts to limit fragmented state oversight.

How long is Anthropic’s lease with SpaceX? Opinions vary.
TechCrunch AI17 days agoBusinessTechCrunch reports that Elon Musk is publicly recasting xAI’s large Anthropic compute deal as short-term and cancellable. However, SpaceX’s own S-1 filing describes payments continuing through May 2029. The discrepancy raises questions about the deal’s duration, financial commitment, and how AI infrastructure obligations are being presented publicly versus in formal disclosures.
RSI is the new AGI — and it’s just as hard to pin down
TechCrunch AI17 days agoCommentaryTechCrunch reports that recursive self-improvement, or RSI, is becoming a new AI industry fixation, much like AGI. Researchers and startups including Recursive Superintelligence, Auto-Research, AutoScientist, and Disarray are exploring ways for AI systems to automate parts of AI research. But experts caution that AI-assisted research is not the same as fully autonomous self-improvement, especially while models still struggle with long-term self-direction and verification.

I think Anthropic and OpenAI have found product-market fit★ 76
Simon Willison's Weblog18 days agoCommentarySimon Willison says Claude Code/Cowork and OpenAI Codex have changed the economics of frontier AI. Personal subscriptions can still be bargains for heavy users, but enterprise plans are increasingly priced like API token usage. His core claim is that coding agents burn far more tokens, yet deliver enough value to high-paid knowledge workers that companies will pay materially more.
AI tried to bury this politician — now people have actually heard of him★ 72
The Verge AI18 days agoRegulationThe Verge frames New York’s 12th District Democratic primary as a proxy fight over AI regulation. OpenAI-linked backers and an Anthropic-backed PAC are spending on opposite sides of Alex Bores’ congressional run. The irony is that attacks meant to weaken Bores may have made him more visible, turning a local race into a national signal about AI political power.
Claude Code as a Daily Driver: Claude.md, Skills, Subagents, Plugins, and MCPs
Hacker News (AI keywords)18 days agoTutorialBased on the title, the article appears to cover advanced Claude Code workflows rather than casual AI coding use.

Choosing to Stay Human★ 74
One Useful Thing (Mollick)19 days agoCommentaryEthan Mollick warns that frictionless AI use can produce hollow writing, weaken learning, and encourage cognitive surrender. He contrasts poor uses of ChatGPT that shortcut effort with tutor-like AI systems that improve learning by pushing students to think. The core argument is not to reject AI, but to intentionally decide which tasks to offload and which human capabilities to preserve.
