 The `aspire agent init` command initializes skill files and MCP (Model Context Protocol) server configuration for your development environment. It presents an interactive multi-step flow to configure AI coding agent support:
 
 1. **Select skill locations** — choose where skill files are installed (Standard `.agents/skills/`, Claude Code `.claude/skills/`, GitHub Skills `.github/skills/`, OpenCode `.opencode/skill/`). The **Standard** location is the only option that defaults as pre-selected.
-2. **Select skills and tools** — choose which skills to install (Aspire skill, Playwright CLI, dotnet-inspect skill). All options are pre-selected by default.
+2. **Select skills and tools** — the available skill catalog is loaded from the Aspire skills bundle manifest, so the list includes all bundle-provided skills (such as `aspire-init`, `aspire-monitoring`, and `aspire-orchestration`) in addition to the CLI-defined skills (`playwright-cli`, `dotnet-inspect`). All catalog skills are pre-selected by default, except one-time workspace-wiring skills (such as `aspireify`) that are omitted from the defaults when running against an existing project.
 3. **Apply selections** — installs the chosen skills into each selected location and sets up the MCP server connection.
 
 The command also removes skill files from any locations that were deselected, keeping your workspace clean.
