Start here. Headline count of everything in a directory that is addressed to an AI agent rather than to you: instruction files, hook commands wired to run automatically, MCP servers the repo declares, and skills/commands/subagents it ships. Use before working in a repo you did not write, or when reviewing a PR that touches agent config.

Every CLAUDE.md, AGENTS.md, .cursorrules and equivalent in the checkout, with size, estimated token cost, and what each one's @import lines pull in — including imports that resolve outside the repo. File contents are never returned; open the paths yourself.

Hook commands declared in the checkout's .claude/settings.json and settings.local.json — shell commands wired to fire on agent events such as tool use, session start or prompt submit. Shows the command, its trigger, and whether the script it references lives inside the repo, outside it, or is missing.

MCP servers declared by the checkout (.mcp.json and equivalents) — the launch command, whether it fetches code from a package registry at start time, filesystem paths it is granted outside the repo, and the NAMES of environment variables it expects. Values are never read.

Skills, slash commands, subagent definitions and plugin markers shipped inside the checkout's .claude/ or .agents/ directories (root, or one to two levels down — monorepos put them per package). These become available to an agent working in this directory. Counts distinct extensions and the markdown files they carry. Names and sizes only — contents are never returned.
