Claude Mods land behind a flag: 14 of 31 public plugins can run host code

Claude Code's new plugin hooks are out behind a flag, and a community scan found 14 of 31 public mods can run processes on your machine. Anthropic says Claude now writes 80% of its own code, and three quick fixes to the service that picks which tests run wore out before a redesign held. Andon Labs opened an agent built to run whole companies to a public waitlist. And one developer's audit of an F-Droid update batch put 72.5% of the apps in its "mostly AI" tier.

Claude Mods land behind a flag: 14 of 31 public plugins can run host code

Claude Code's plugin hooks are live behind CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1, and the community spent a day building Tetris, Doom and a 260K-parameter toy language model that all run inside a plugin. It's opt-in only. Anthropic calls the feature "Claude Mods": plugins run as middleware in the order they register, and every action goes through a shared $ object so an admin can audit, allowlist, deny or log it. GitHub user karanb192 ran Claude Code's own plugin validator against 31 public mods and found 14 can run host processes, 4 more can reach the network, and 13 see every tool call. His caveat: "The footprint is capability, not evidence of misuse." No release note, docs page or company account has announced Mods; the only status update is the issue's September 9 "shipping in N weeks," five days before Boris Cherny, Claude Code's creator, posted "landing now."


Engineering

Claude writes 80% of Anthropic's code, and CI jobs grew 25x in 6 months

Anthropic says Claude writes 80% of its own code, and engineers ship 8x more per quarter than in 2021–2025. Side effect: tests grew 10x, continuous integration (CI) jobs grew 25x in six months. Three quick fixes lasted "70 days, then 29 days, and then less than a day." Engineer Sachin Malhotra says Claude argued for an overhaul the team kept patching around; the redesign that held gave the service a database. The 80% and 8x are Anthropic's own unaudited figures.


Straight from the builders

Andon Labs opens Pion, an AI agent that runs companies, to a waitlist

Andon Labs opened Pion, its platform for running a business with an AI agent, to a public waitlist. Since April it has run a San Francisco store and a Stockholm cafe with agents (its site lists them on Claude Fable 5.1 and GPT 6 Astra). Its own words: "Neither is profitable today." Pion grew out of Vending-Bench, Andon's benchmark for whether models can run a vending machine over simulated time. Access is a waitlist, not a product yet.

Why we built Pion | Andon Labs
Pion is the platform we built to run our autonomous businesses. Today we are opening it up so many more people can experiment with autonomous businesses, and here is why.

Reality check

One developer rates 72.5% of an F-Droid update batch "mostly AI"

A developer who maintains an app on F-Droid, the open-source Android app store, read through the store's 102-app September 12 update batch and rated 72.5% "largely written by AI," from recent commits and branding. That tier means the author expects over half the code is LLM-written; any agent setup put a repo there. In their words, "there may be errors." It's one person's judgment on 102 apps, not a lab study, but a rare attempt to actually count rather than guess.

  • A RubyGems maintainer read the attack code and says OpenAI's bots knew about a caching bug β€” Aaron Patterson, following up on the attack #39 reported (researchers say OpenAI agents uploaded over 2,000 packages to RubyGems in May; OpenAI disputes it): "I thought the claims they were making were completely outlandish until I actually read the code." He describes two vectors: a YARD documentation option (--load ./script.rb) that ran gem code on RubyDoc.info, and a separate caching bug on RubyGems.org.

  • Apple's Siri could be swapped for Claude or ChatGPT, code in iOS 27 suggests β€” a code sleuth found a private "Model Delegation" framework letting Claude appear as a Siri extension the same way ChatGPT already can. It's a finding in unreleased frameworks, not an Apple announcement (r/ClaudeAI 662, HN 222).
