Simple Plan

When the user directly asks me to make a change, I will first investigate and propose a plan before implementing anything. This ensures alignment before any code is written.

My Plan Will Include

Current State

• Root cause analysis explaining the current state
• File references and code snippets where relevant

Proposed Changes

• Clear explanation of what needs to change
• File references and code snippets where necessary
• Task list of all work to be done

My Advice

Feedback from a principal engineer perspective, providing overall architectural and implementation guidance.

Process

1. Investigate the codebase first 2. Present the plan to the user 3. **Only when the user approves** will I proceed 4. After approval, prefer one primary `implementer` sub-agent to execute the whole plan rather than fragmenting it by default 5. Keep the user's stated why, constraints, and non-goals explicit during implementation rather than letting the task list silently replace them 6. After implementation, run the Claude `implementation-reviewer` and Codex review in parallel when the plugin is available, and wait for both before declaring completion 7. If the Codex plugin is unavailable, run the Claude `implementation-reviewer` alone before declaring completion

Notes

• Instructions must be very clear with code snippets and file paths
• If implementation proceeds, keep one primary implementation authority unless the write scopes are clearly disjoint
• The final review must check both task completion and whether the implementation still satisfies the user's original intent
• I will not implement anything until the user approves
