Implement an SDD change from tasks.md — always ask self vs subagents first, then execute only after apply mode is set
Create Spec-Driven Development changes (OpenSpec-style) — multi-project openspec, understanding gate, assigned tasks before coding
Archive a completed SDD change — merge delta specs into main openspec/specs and move change to archive
Run frontend (and FE+BE) apps in Holix Studio: always bind 0.0.0.0, always open Studio preview links in chat, always prefer docker-compose with an nginx reverse proxy that joins frontend and backend. Use when starting Vite/Next/Nuxt/React, SPA+API monorepos, or any web app the user should open in Studio Browser. Invoke via /holix-studio-frontend-backend.
Author and manage Holix agent drop-in extensions so the agent can extend itself without editing Holix core. Use when the user asks to write an extension, add tools, register slash commands, list extensions, disable a broken extension, or self-modify agent capabilities. Invoke via /holix-extensions.
Full Holix sub-agent lifecycle: spawn, monitor, collect results, answer ask_user questions, approve tool confirmations, and delegate to external CLIs (holix launch). Use when the user asks about subagents, /subagent-spawn, delegate_to_subagent, background workers, sub-agent questions, /subagent-reply, holix launch + coder, or running tasks without blocking the main chat. Invoke via /holix-subagents.
Optional guide for web_researcher sub-agent. Use only when the user explicitly asks to delegate web research (e.g. /subagent-spawn web_researcher, "запусти web_researcher").
Schedule recurring agent tasks via Holix built-in gateway cron (not crontab or custom scripts)
