Anthropic is an AI safety and research company working to build reliable, interpretable, and steerable AI systems.
This Privacy Policy explains how we collect, use, disclose, and process your personal data when you use our website, Claude.ai, or other Anthropic products and services (the “Services”).

Claude Pro/Max plans expose a usage API at https://claude.ai/api/oauth/usage that returns two utilization counters:
five_hour.utilization — a rolling 5-hour window (well documented)seven_day.utilization — described as a "weekly" capThe seven_day object also contains a resets_at field. Monitoring this field over ~11 days (June 9–20, 2026) revealed that the "weekly" limit does not reset every 7 days — it resets every 72 hours.
AI coding agents are useful precisely because they can run tools, edit many files, execute tests, install dependencies, and iterate quickly. That same ability makes them risky in YOLO mode: a mistaken command, broad glob, broken script, or overconfident refactor can damage a working tree faster than a human can react.
The goal is not to make agents harmless. The goal is to make common failures recoverable.
Ordinary file deletion should moves files and directories to the trash instead of permanently unlinking them.
That matters a lot when using coding agents, especially in YOLO mode. Agents can
run broad shell commands quickly, expand globs, execute cleanup scripts, or apply
generated commands with more confidence than the situation deserves. A trash-backed
rm does not make destructive work impossible, but it turns many accidental
deletions from irreversible data loss into a recoverable operation.
This document describes CORS (Cross-Origin Resource Sharing) preflight support for all LLM API endpoints used by the agent specs in this project.
CORS is a browser security mechanism that restricts cross-origin HTTP requests. Before making an actual request, browsers send a preflight OPTIONS request to check if the server allows the cross-origin request. The server must respond with appropriate Access-Control-Allow-* headers for the browser to proceed.
The Secret Service API is a D-Bus interface
(org.freedesktop.secrets) implemented by GNOME Keyring. Applications use it to store and retrieve
credentials. Once your desktop session is unlocked (at login), any process running as your user can
talk to this interface without further authentication.
