 The CLI is designed for AI agents that can run shell commands.
 
-Agent skill guides are available at `.claude/SKILL.md`, `.codex/SKILL.md`, `.cursor/SKILL.md`, `.windsurf/SKILL.md`, and `docs/SKILL.md`.
+### Install the DeployHQ skill into your agents
+
+`dhq skills install` detects the AI coding agents on your machine and installs
+the DeployHQ skill into each one's native format, so the agent knows how to
+drive `dhq`. It's also offered automatically during `dhq hello`.
 
 ```bash
-# Install agent plugin (Claude Code, Codex, Cursor, or Windsurf)
-dhq setup claude
+# Detect installed agents and show their skill status
+dhq skills list
+
+# Install for every detected user-scope agent (Claude Code, Cursor, …)
+dhq skills install
+
+# Install for a specific agent (use the name from `dhq skills list`)
+dhq skills install --agent claude-code
+
+# Project-scope agents write into the current repo, so they're opt-in:
+dhq skills install --agent copilot
+```
 
+Twelve agents are supported — Aider, Antigravity, Claude Code, Cline, Codex CLI,
+Continue.dev, Cursor, Gemini CLI, GitHub Copilot, Kiro CLI, OpenCode, and Windsurf.
+**User-scope** agents install into your home directory and are picked up by the
+bare `dhq skills install`; **project-scope** agents write into the current
+repository and require an explicit `--agent` flag so login never mutates a repo
+as a side effect.
+
+`dhq setup <agent>` is a narrower alternative that installs the agent plugin for
+a single tool (Claude Code, Codex, Cursor, or Windsurf), with `--project` for
+project-level installs.
+
+### Other agent helpers
+
+```bash
 # Full command catalog with agent safety metadata
 dhq commands --json
 
 # Agent-optimized workflow
 DEPLOYHQ_AGENT=my-bot dhq deploy -p my-app --json
 ```
 
+Standalone skill guides are also available at `.claude/SKILL.md`,
+`.codex/SKILL.md`, `.cursor/SKILL.md`, `.windsurf/SKILL.md`, and `docs/SKILL.md`.
+
 ### Non-Interactive Mode
 
 Use `--non-interactive` to guarantee the CLI never prompts. Auto-enabled when output is piped.
