zksync-js

Validate ethers and viem adapter parity for zksync-js when core or adapter behavior changes. Detect mismatches, enforce documented exceptions, and protect core-to-adapter contract consistency.

Enforce zksync-js public API safety when diffs touch package exports, typesVersions, entrypoint barrels, or exported core types. Validate checklist, classify compatibility impact, and require docs/changelog alignment.

Use this skill when changing ABI sources/registry, contract clients/wrappers, calldata construction, contract method calls, event/log decoding, or any SDK behavior directly derived from ABI definitions. Do not use this skill for unrelated utilities, docs formatting, CI/release config, or non-contract refactors.

Determine and enforce the correct zksync-js verification loops (fast, adapter e2e, docs) based on changed files, PR completion state, and CI failure context.
