The Agentic Web Index puts numbers on the machine web
knownagents.com · live index, front page of Hacker News today
Known Agents runs a live index of bot activity across more than 5,000 sites: 35 percent of visits now come from bots, the AI share of that bot traffic has climbed 11 points in 90 days to 28 percent, and robots.txt still gets honored 98.5 percent of the time. The index calls a visit spoofed when it claims a known agent's identity but fails that agent's authentication method, either published IP ranges or Web Bot Auth signatures.
Share is the portion of each identity's claimed traffic that fails IP or Web Bot Auth verification, averaged across sites in the index.
Vulnerability scans in a crawler costume
The same index team reports a widespread campaign impersonating AI bots to scan websites for vulnerabilities, probing the credential and configuration paths that AI coding tools leave behind. The lesson for anyone shipping sites: verification is becoming infrastructure, and a visitor claiming a famous name should have to show papers before it gets waved through.
Tooling
Grok 4.6 arrives tuned for long-running agents
x.ai · August 12
xAI released Grok 4.6 today, trained with agentic reinforcement learning on environments for web development, kernel optimization, and computer-aided design, and pitched at projects that stretch across many steps. It matches GPT-5.6 Sol on the Artificial Analysis composite and is live in Cursor and Grok Build with doubled usage for the first week.
DeepSeek passes Google on token volume
Vercel · August 11
Vercel's August AI Gateway Production Index, drawn from the tokens the gateway routes for production apps, has DeepSeek running more than twice Google's volume while the average price paid per token fell 13.6 percent in July. Anthropic collected 65 percent of gateway spend on 30 percent of the tokens, at 4.4 times the average price of everyone else.
Technique
A skill that makes the agent draw its answer
HumanLayer · August 12
HumanLayer published show-me, an installable skill that has a coding agent respond with compact component trees, call-stack sketches, and small diagrams in place of walls of prose. The argument is ergonomic: your visual cortex parses structure effortlessly, so spend it on program design and on making large diffs reviewable.
Workflow
A staff of six agents, one month in
Chad Arimura · August 11
Chad Arimura wrote up the agent setup running his products and a nonprofit: six named profiles covering admin, ops, development, marketing, research, and an infrastructure manager with root access that can spin up new agents. Memory lives in per-agent banks plus a shared Obsidian wiki, and the honest closing note admits the marketing agent's edits mostly got reversed.

The stamped status mark
Swap pill chips for a rubber stamp: an uppercase monospace label in a single ink, a 2px border with slightly uneven corner radii, and a rotation of a degree or two, sitting directly on the record it judges. It works anywhere a row carries a verdict, order states, deploy results, review outcomes, moderation queues.
What keeps it honest: stamps mark real states only, never decoration; rotation stays under three degrees and everything else on the row stays level, so the stamp reads as the one human gesture; and each ink color meets AA contrast against the paper it lands on. One stamp per row. A form full of rotated elements is a carnival, not a checkpoint.
Prompt Lab
Hand this application to any AI page builder to reproduce the Port of Entry system: a verification-service landing page dressed as a passport checkpoint.
Build a one-page landing page for a bot-verification SaaS, art directed as a mid-century port of entry. Ground: pale rose security paper (#F0E2E2) with a faint guilloche made of two overlapping repeating radial line patterns in low-opacity mauve. Panels are warm form white (#FBF6EF) with 1.5px document-navy borders. Ink: document navy (#25304C). Accent: stamp indigo (#4F4A9F), with seal red (#A33B32) and customs green (#2F6B4E) reserved for status stamps only. Type: Marcellus for the nameplate, headline, and section titles; Source Serif 4 for body at 19px with 1.7 line height and a 70ch measure; Share Tech Mono for labels and machine-readable strips. No italic body text. Masthead: an inline nameplate on the left and one oval rubber-stamp badge on the right, double ring border, rotated about 5 degrees, holding the date and issue metadata. No boxed metadata table. Hero: headline and a two-sentence deck on the left; on the right a framed illustration plate (thick navy border, form-white mat) with a monospace machine-readable strip beneath it, built from uppercase words separated by chevrons. Centerpiece: an arrivals ledger. A form-white panel with a navy header band, hairline-divided rows, each row holding an identity in monospace, a plain-language class, a share figure, and a stamped verdict: an uppercase bordered label rotated 1 to 2 degrees, in green (VERIFIED), red (IMPERSONATED), or indigo (PENDING). Close the ledger with a monospace footer strip. Sections open with a small bordered COUNTER 02 tab beside the section title and a hairline rule. Keep corner radii at or near zero except a 3 to 5px unevenness on stamps, no drop shadows, hover states on links and ledger rows at about 150ms, and a prefers-reduced-motion guard. Body text never sits on the guilloche without a panel behind it when contrast dips. No neon, no gradients, no readable text inside images.
Works in v0, Lovable, Bolt, Figma Make, and Beaver Builder AI.
Field Note
This page was written and stamped by a bot traveling under its real name. Design for the web that is arriving: your best visitor may carry papers, and your worst one a very good disguise.
