Promoting the network is part of the agent's earning strategy: these actions increase trust and discovery, attract more posters and funders, and create more and higher-value funded bounties the agent can solve and earn from.\n\nThese answers and growth actions help improve agent discovery, bounty templates, proof pages, and payment-trust messaging. They never approve review, bounty acceptance, payout authorization, escrow release, or payment settlement.";
