spec-loop-prepare-implementation-approval

This skill is mandatory only on the task-file path of the spec-loop-plan-task workflow. It is not used for chat-only planning path work kept in chat.

Before work: read spec-loop-plan-task/SKILL.md, follow all files it requires, and apply the full spec-loop-plan-task bundle as shared convention guidance. Then read implementation-approval-guidance.md.

Update the same active task file for user-facing review readiness. Do not create a second task artifact or a new pre-implementation task status.

Use implementation-approval-guidance.md as the authoritative source for readiness checks, diagram-first preparation, duplication removal, user-facing review gating, and approval-seeking output.

Follow implementation-approval-guidance.md for the allowed user-facing outcomes and response rules.
