调研方向

Start from test/declared-decimals.test.ts (commit 26875a5) to see how a 402 that declares extra.decimals: 18 is checked against the pins through dryRun, createAgentPay and agentSafeGuard. Build the shared mock route with startMockServer from @deepfirstsearch/agent-pay/testing, then add one test each in integrations/ai-sdk, integrations/langchain, integrations/agentkit and integrations/mcp. Done means each CI job is green and every test asserts the same over_cap result with zero signatures.

描述

enhancement good first issue

test/declared-decimals.test.ts (added in 26875a5) checks that a 402 declaring extra.decimals: 18 can't make a large USDC amount slip past the pins, through dryRun, createAgentPay and agentSafeGuard. The same guarantee should also hold through the framework integrations, which are where most agents actually call us.

What: a small shared fixture (a mock route that declares its own decimals) reused by one test in each of integrations/ai-sdk, integrations/langchain, integrations/agentkit and integrations/mcp: the paid tool refuses the oversized amount and signs nothing.

Done when: each integration has the test, green in its CI job, and the assertion is the same across all four (over_cap / amount above the pin, zero signatures). Reuse startMockServer from @deepfirstsearch/agent-pay/testing; no new dependency.
