Anchor 1.0+ ships Rust + LiteSVM tests as the default scaffold from `anchor init`. Remove the older TypeScript test guidance (node:test via tsx, @solana/kit, @solana/web3.js, Codama clients for tests, .rpc()). Document the bare anchor init test pattern, the two scaffold fixes needed (package_manager = "npm", drop ts-mocha/mocha/chai from package.json), and the optional solana-kite ergonomic layer used by quiknode-labs/solana-program-examples.
…t rule Anchor wraps the test step; running `anchor test` runs the full pipeline (build → deploy → cargo test) which is what we actually want to verify green before declaring success. `cargo test` alone misses the build/deploy step. The factual references to what's literally in Anchor.toml's [scripts] section remain as `test = "cargo test"` because that's the actual default config value.
Mike's phrasing: 'Anchor programs (since 1.0.0) use Rust + LiteSVM instead of TypeScript' is clearer than 'Anchor program tests are Rust + LiteSVM' \u2014 it names the version that introduced the change and explicitly contrasts with the prior TS pattern.

Overview
Updates
SKILL.mdto standardize Anchor program testing on Rust + LiteSVM (andanchor test) instead of TypeScript/Mocha-era patterns.Adds detailed guidance for LiteSVM-based integration tests (project init flags, scaffold expectations, post-init fixes like
package_manager = "npm"and removing JS test deps, example test structure, optionalsolana-kitehelpers, and common pitfalls like blockhash reuse/account deserialization), and clarifies TypeScript guidance as offchain-only for Anchor programs.Reviewed by Cursor Bugbot for commit c110b72.
