What problem does it solve? It prevents developers from claiming work is done based on incomplete checks by enforcing a strict verification ladder across the tyche monorepo's TypeScript apps and Rust Solana program, including live devnet reconciliation. ## Core Features & Use Cases - Per-package verification ladder: Runs typecheck, test, lint (with --max-warnings=0), and build in order for every touched package, including shared rule packages. - Rust/SBF contract testing via Docker: Executes cargo checks, dual-feature clippy, and single-threaded SBF instruction tests inside a pinned toolchain container. - Live devnet verification: Guides dry-run-then-broadcast settlement, claims, and input seeding with on-chain, API, and audit reconciliation plus idempotency checks. - Use Case: After fixing a settlement bug in apps/worker, use this Skill to run the full ladder, rebuild the SBF program, dry-run the settlement runner, broadcast, and confirm the re-run is a no-op. ## Quick Start Verify my changes to apps/worker and the Solana program correctly before marking anything done.
