NEAR (wallet-sdk-core granular skill)

Granular skill for NearWalletProvider — the low-level NEAR wallet for backend / Node / non-React flows. Source-of-truth reference lives in the parent broad skill's knowledge tree; this file is the focused workflow only.

Step 1 — Clarify with user before coding

1. New code or v1 → v2 port? New → § Integration. Port v1 → § Migration (almost always a no-op here).
2. Private-key or browser-extension config? NEAR discriminates by field presence (no type): PK = { rpcUrl, accountId, privateKey } where privateKey is the full 'ed25519:…' string; browser-extension = { wallet: NearConnector } (from @hot-labs/near-connect). Mutually exclusive — pick one.
3. Finality vs speed? defaults.waitUntil is 'FINAL' by default — lower ('EXECUTED') for faster scripts with the usual revert caveats.

Integration workflow (new v2 code)

1. ../integration/knowledge/ai-rules.md — DO / DON'T (read first).
2. ../integration/knowledge/architecture.md — BaseWalletProvider, dual-config discriminants, shallow defaults merge, library-exports.
3. ../integration/knowledge/features/near.md — full config union, NearWalletDefaults, methods (getRawTransaction / signAndSubmitTxn), gotchas.
4. Setup recipe → ../integration/knowledge/recipes/setup-private-key.md or ../integration/knowledge/recipes/setup-browser-extension.md; then ../integration/knowledge/recipes/sign-and-broadcast.md, ../integration/knowledge/recipes/defaults-and-overrides.md.
5. Lookups → ../integration/knowledge/reference/provider-classes.md, interfaces.md, chain-support.md.
