Impl Code Check

Review the recent implementation diff (uncommitted or user-specified scope). Read code. No guessing. If clean, write "none".

Scope

• Target: latest implementation changes. Honor user-specified scope
• Do not fix. Report only. Fix only if user asks

Output (these 4 headings only)

Short bullets. No long quotes, no full file lists. Paths only when needed.

Bug risk

Honest take: is this change bug-prone? One-line why. Concrete risks as bullets.

Dead code

Unused funcs, unreachable branches, stale call paths, leftover config keys. Else "none".

Missing tests

Gaps / tests worth adding. High → low priority. Else "none".

Error handling

Missed nil / timeout / cancel / partial failure. Else "none".

Rules

• Save tokens: no preamble, summary, or praise
• Prefix severity: high / mid / low when it differs
• Code blocks only for decisive snippets (few lines)
• Reply in English unless user asks otherwise
