Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

`calculate_tax_credit`	Calculate an auditable tax-credit scenario. credit is 45Q, 45V, 45Y, 48E, or 45X. facts must contain the explicit credit-specific eligibility facts; missing facts return indeterminate. This is not tax or filing advice. Price: $2.00 per call after 10 free calls/day. Pay at /x402/taxcredit-engine/calculate_tax_credit with Base USDC, cash-fund payment_ref through escrow_checkout + confirm_escrow_funding, or use /seats.
`describe_agent`	Return fleet-standard capabilities, version, and pricing.
`get_rule_pack`	Return the bundled rules and official source metadata for one credit.
`list_rule_packs`	List supported credits and the current bundled rule-pack digest.
`verify_tax_credit_result`	Verify an engine result's audit_sha256. Pass the prior result object as JSON; any changed amount, fact, rule step, or source digest fails.

Schemas: list_tools.
