Use when indexing contracts deployed by factory contracts at runtime. contractRegister API, dynamic contract config (no address), async registration, and same-block event coverage.

Use when writing or editing event handlers. Handler registration, context API (entity CRUD, getWhere queries, chain, log), spread updates, indexer runtime API, and common pitfalls.

Use when deploying an indexer across multiple chains. Entity ID namespacing to avoid collisions, chain-specific configuration patterns, and the context.chain runtime API.

Use when needing transaction-level data in handlers. Configure field_selection to include transaction fields on events, and access via event.transaction. No native transaction handler — access through event handlers.

Develop Sury with the spec CLI. Use whenever changing Sury core logic (packages/sury/src) — specs snapshot codegen, bundle size, and type-cost metrics that every change must keep or improve — and when adding/editing packages/sury/specs/*.yaml.

Debug and fix failing tests using Wallaby.js MCP tools. Use when investigating test failures, debugging test errors, inspecting runtime values, checking code coverage, or updating snapshots.
