…adapters - Rate-limit WebhookVerifier re-fetch on unknown kid to prevent DoS via forged signatures with random kid values (60s cooldown, configurable) - Extract duplicated tool-lookup-and-execute logic from openai, anthropic, and mcp adapters into shared findAndExecuteTool() in catch-errors.ts - Preserve non-JSON response body context in http.ts error messages instead of silently swallowing parse failures - Wrap identity-linking token endpoint JSON parse in try-catch and include error response body in UCPOAuthError messages for debuggability
- Extract parseResponseBody() in http.ts to read body as text first, preserving raw content for non-JSON error messages instead of losing it to consumed body streams - Fix unsafe `any` return from JSON.parse and res.json() (lint error) - Wrap OAuth metadata res.json() in try-catch in UCPClient.ts to surface clear error when endpoint returns non-JSON - Replace inline import type with top-level import in catch-errors.ts
- Make parseMessages fallback try common field names (content, text, message) before defaulting to 'Unknown error' — handles servers that use non-spec field names - Fix mock server error responses to use spec-correct `content` field and include `code` in messages array - Add scripts/runtime-review.ts: comprehensive runtime integration test covering connect, all adapters, full checkout flow, error handling, webhook verification, idempotency keys, and immutability
…pabilities
Add CatalogCapability (search + getProduct) and CartCapability (create, get,
update, cancel) with full agent tool support and spec-compliant REST paths.
- Catalog uses split capability detection (catalog.search + catalog.lookup)
with extensions pattern matching checkout's fulfillment/discount model
- Cart uses plural /carts paths and POST /carts/{id}/cancel per spec
- Re-export all new SDK v2.0.0 schemas (catalog, cart, amount, error types)
- Agent tools: search_catalog, get_product, create_cart, get_cart, update_cart,
cancel_cart with JSON Schema parameters and execute functions
- 382 tests passing, 91%+ coverage
BREAKING CHANGE: CardPaymentInstrumentSchema removed (replaced by
CardPaymentInstrumentAvailableCardPaymentInstrumentSchema).
TotalTypeEnumSchema removed (no replacement in SDK v2.0.0).
UcpReverseDomainNameSchema renamed to ReverseDomainNameSchema.

- schemas.ts: only import schemas needed for aliases; use direct
`export { ... } from '@omnixhq/ucp-js-sdk'` for pass-throughs
- index.ts: replace 200-line schema listing with `export * from './schemas.js'`
Each schema now appears once instead of three times.
