ante-sdk-protocol-alignment

# Ante SDK protocol alignment Use this skill when a request changes, reviews, or investigates the protocol boundary between this TypeScript SDK and `AntigmaLabs/ante`. The Rust `crates/protocol-shape/src/msg.rs` definition is authoritative for wire names and payload shapes. Do not infer semantics from variant names alone. ## Establish the protocol delta Run `npm run check:protocol` to compare the checked-out SDK with the current upstream default branch. For a reproducible or offline comparison, run `node scripts/check-protocol-drift.mjs --local <ante-checkout>` or pass an explicit `--ref`. The report fails whenever the daemon has an Op or Evt variant the SDK does not cover. Do not weaken the comparison merely to make a check pass: implement the capability or obtain an explicit decision to leave it unsupported. ## Make an alignment change Read the complete Rust declaration and follow its payload through the SDK before editing. In particular, assess wire serialization in `src/protocol/wire.ts`, public types in `src/types.ts`, state/lifecycle behavior in `src/session/client.ts`, and higher-level `Query` behavior where relevant. For a new event, decide whether it must update session state, resolve/reject a pending operation, emit an `SDKMessage`, or remain intentionally unsupported. For a new operation, define the public API and its payload rather than exposing a name-only escape hatch. Preserve unrelated compatibility behavior and update README/changelog claims when the public API changes. Add focused tests that assert the actual serialized operation or emitted message. Finish with `npm run check` and re-run the protocol check against the intended source ref. Do not commit, push, publish, create an Issue, or change remote automation unless the user explicitly requests it. ## Boundaries This repository intentionally does not run protocol alignment as an unattended GitHub Action: detected drift needs semantic review before an SDK implementation can be proposed. Treat a protocol report as an engineering review input, not permission to generate code automatically.
