Setup guides
Short, sourced answers to the configuration questions people search for most.
Cursor: allow all terminal commands (Run Everything, allowlist, sandbox)
How do I let Cursor's agent run commands without asking?
Claude Code: allow commands without prompts (permission modes and allow rules)
How do I stop Claude Code asking for permission every time?
Codex CLI: approval and sandbox modes (and what --yolo does)
How do I make Codex run commands without asking?
Gemini CLI: YOLO mode, auto_edit and allowing specific shell commands
How do I stop Gemini CLI asking before every tool call?
Cursor Privacy Mode: telemetry, training and data retention
Does Cursor store or train on my code?
Claude Code telemetry and data retention: what is sent and how to turn it off
How do I disable Claude Code telemetry, and how long is my data kept?
Gemini CLI: turn off usage statistics and telemetry
How do I disable Gemini CLI telemetry?
CLAUDE.md: where it goes, how it loads, and how it works with AGENTS.md
Where do I put CLAUDE.md, and does Claude Code read AGENTS.md?
Claude Code hooks: format on save, block risky edits, get notified
How do I run a command automatically when Claude Code edits a file?
Standards, explained briefly
Current versions, governance and when to use each one.
MCP
Current revision 2026-07-28The standard way to connect an agent to tools, data and services. One server works in every MCP client.
A2A
Stable, v1.0.1 (May 2026)Lets independent agents discover each other, delegate tasks and stream results, whoever built them.
SKILL.md
Supported by 45+ agent productsPortable folders of instructions, scripts and references that an agent loads only when a task needs them.
AGENTS.md
Read by 20+ coding agentsA README for coding agents: build steps, test commands and conventions in one file at the repo root.
ACP
40+ agents implement itLets any editor drive any coding agent, the way LSP lets any editor use any language server.
UCP
Shopping spec established; lodging in draft; food comingCommon building blocks for agents to discover products, build carts, check out and handle orders.
