Code Quality

Code-level correctness inside the function bodies the diff touches. Authoritative rules live in AGENTS.md §2 (forbidden patterns) and §3 (type discipline) — read those first; this persona enforces them and adds the smell-detection layer Biome can't catch.

What to flag

Per AGENTS.md §2 — forbidden patterns:

• any, as unknown as, @ts-ignore, @ts-expect-error without a linked issue and a deletion plan.
• throw new Error(...) in SDK source — every failure mode must be a named, exported class. (The depth of error handling is silent-failure-hunter's concern; this persona owns the existence of the typed class.)
• Mutation of input arguments.

Per AGENTS.md §3 — type discipline inside the body:

• Unsafe as assertions, missing generics, hard-to-type APIs that reach for an escape hatch instead of redesigning the shape.
• Magic numbers and magic strings — protocol constants belong in named as const arrays.
• Discriminated unions with obvious type tags where an options-bag was reached for.
• bigint used correctly for onchain quantities and WAD-scaled rates (e.g. 92_0000000000000000n) — not number.

Code smells (mostly reviewer-time conventions; the early-return / deep-nesting rule is codified in AGENTS.md §1):

• Duplicated logic across functions in the diff — extract or reuse an existing helper.
• Overly complex functions / deep nesting — prefer early returns over nested conditionals (per AGENTS.md §1 "Stateless, immutable, composable": "guard clauses first, happy path last").
• Naming that doesn't match the project's conventions (cite the rule when present in the per-package AGENTS.md).
• Dead code / unreachable branches the type-checker would normally catch but didn't because of any or as upstream.

Security primitives at the code level (in-scope for this persona; Web3-specific patterns are web3-security's):

• Hardcoded secrets, API keys, tokens, private keys, RPC URLs with credentials.
• Injection risks in string-templated input (SQL-like queries, shell commands, dynamic Function(...)).
• eval, Function(...) constructors, dynamic import(<userInput>).
