Simplify Code

Review code for scope, reuse, quality, efficiency, clarity, and altitude issues, then fix them.

Step 1: Determine the Scope

Determine what to review:

• If a specific diff command was provided (e.g., git diff --cached), use that.
• If a file list or directory was provided, review those files directly (read the full files, not a diff).
• If neither was provided, determine the appropriate diff command (e.g., git diff, git diff --cached, git diff HEAD) based on the current git state. If there are no git changes, review the most recently modified files mentioned in the conversation.

Step 2: Launch Six Review Agents in Parallel

Emit all six Agent tool calls below in one assistant message. Do not send one and await its result before sending the rest. Run them in the foreground so all their results return in this turn. Each Agent call uses model: "opus" and no name. Pass the scope from Step 1 to each agent. Every agent's prompt must direct it to treat the shared working tree and its git index as read-only and to reach its findings by reading and reasoning; fixes happen in Step 3. HEAD stays where it is: read other refs with git show <ref>:<path> rather than git checkout or git switch.

Agent 1: Scope Review

Review the changes for code that should not exist:
