## Honesty policy
- Not personalized investment, financial, tax, or legal advice.
- Market-data tools (liquidity, greeks) are analytics — not trade recommendations.
- Banking/tax microservices record ledger events; they do not move real money unless your integration does.
- List prices are starting points; negotiated matches may differ.
- Removed services are not listed. Do not purchase or execute unpublished skill names.
- Coming-soon services are listed for preview — not purchasable or executable yet.
- BYOK outbound requires buyer Instantly/OpenAI keys; platform does not provide shared inboxes.
- Do not publish bearer tokens, QA bypass tokens, or third-party API keys in public repos.
