Use this skill as the explicit orchestration layer for broad Rust architecture and product engineering work. For ordinary local Rust edits, use rust-expert or a specialist skill instead.
Invocation Rule
Do not invoke this skill implicitly for normal Rust questions, compiler errors, single-crate fixes, broad architecture wording, or isolated CLI/TUI/Tauri/service work. Invoke only when the user explicitly names rust-mega-eng for broad, cross-cutting Rust architecture and execution planning.
Operating Model
- Map the product surface: libraries, binaries, services, desktop apps, terminal UI, deployment targets, public APIs, and release obligations.
- Identify canonical ownership: crate boundaries, app/service boundaries, shared domain types, generated code, test fixtures, config, docs, and CI gates.
- Choose leverage first: mature crates, official frameworks, platform conventions, and repo-native workflows before custom infrastructure.
- Split delivery into reviewable lanes: architecture/design, code movement, behavior changes, test hardening, release/distribution, and docs.
- Keep a decision ledger for major choices, with explicit tradeoffs and verification evidence.

Verification
For broad Rust work, define a validation ladder early:
cargo fmt --all --check
cargo clippy --all-targets --all-features -- -D warnings
cargo test --all-targets --all-features
cargo nextest run --all-targets --all-features
cargo deny check
cargo audit
cargo semver-checks check-release
Run only gates that are relevant and available, but report any skipped gate with the reason.
