# Free Models Free capacity serves **delegated** work. You route suitable Sub-Agent Runs to free Models through the `subagent` Tool's per-Run `model` override (`<provider>/<model-id>`, applies only to that Run). You never change the calling Agent's own Model, any stored configuration, or a Project default through this skill, and never do so silently. ## Non-negotiable rules 1. **Tools gate.** A Sub-Agent without tool calling is broken, not cheap. Propose only Models whose catalog record confirms tool support (`vbot model show <id>`), and only ids that appear in `vbot model list` — a configured, usable Connection. 2. **No silent paid fallback.** When a free Model fails or returns unusable output, rotate to another free Model, wait out rate limits, or report the gap. Moving the work to a paid Model spends money and requires the user's explicit consent first. 3. **Quality boundary.** Ask before routing security-sensitive, architectural, irreversible, or otherwise high-stakes work to a weaker Model. Saving cents is never worth silently degrading an outcome the user cares about. 4. **Privacy boundary.** Free tiers are often paid in data — several free endpoints log inputs or train on them. Never put credentials, secrets, or tokens into delegated task text. Flag sensitive content to the user and prefer zero-retention, paid, or local alternatives for it. 5. **Rate limits are real.** OpenRouter free variants allow 20 requests per minute, 50 requests p
