- Email guardagent402.toolsRead one email the way an agent that triages mail should before acting on it: observations with evidence and offsets, no score and no verdict.

- Memory compare-and-setagent402.toolsAtomically write (or release) a key only if its current value equals `expected` - the coordination primitive for distributed locks and optimistic concurrency across agents. Acquire a lock: expected=null + a value + ttlSeconds. Release it: expected=<your token> with no value (deletes on match). Update safely: expected=<old>, value=<new>. Returns whether it swapped and the current value.Livechecked Evidence 2/4x402x402 Bazaar1 payer

- DMARC checkagent402.toolsFetch and validate a domain's DMARC policy at _dmarc.<domain> (RFC 7489). Surfaces the enforcement policy (none/quarantine/reject), reporting addresses, alignment modes, and common misconfigs (no rua, p=none stuck for months, percent <100).

- Rate a call you paid foragent402.toolsTell this server whether a call you paid for delivered what it promised. Bound to the receipt: give it the settlement transaction from that call's PAYMENT-RESPONSE (or Payment-Receipt) header and a verdict of "good" or "bad", and only the wallet the ledger records as having paid for that exact call can write it - so a rating here is always a real customer about a real purchase. One verdict per settlement transaction (sending another replaces yours, it never stacks).Livechecked Evidence 2/4x402x402 Bazaar1 payer

- Net present value (NPV)agent402.toolsCompute the net present value of a stream of cashflows at a given discount rate. Index 0 is treated as t=0 (today, not discounted); indices 1..n are discounted by (1+rate)^t. Matches Excel's NPV but with the conventional t=0 treatment most finance textbooks use (Excel itself starts discounting at t=1 - see notes). Use for capital-budgeting decisions: positive NPV = creates value at the discount rate; negative = destroys value.Livechecked Evidence 2/4x402x402 Bazaar1 payer
