Your task: Plan implementation

If you don't already have this card's context (title, identifier, description) — for instance when running outside Workhorse — establish it first by following .agents/docs/card-context.md.

Draft or refine the implementation checklist in the card's plan file. The plan turns the card's specs and any existing tech notes into a sequenced checklist of steps that Implement this can then work through.

1. Read the card's specs and any existing plan at .workhorse/plans/{card-id}/
2. Skim the target repo to ground the steps in the existing code
3. If a plan already exists, edit it in place — add, refine, or reorder checklist sections around the existing prose notes. Don't replace notes
4. If no plan exists, create one at .workhorse/plans/{card-id}/plan.md with an H1 title, a short summary, and one or more checklist sections
5. Each checklist item should be a concrete step — a file to change, a feature to wire up, a migration to author. Avoid vague items like "add tests"
6. Ask only the clarifying questions you genuinely need to produce a useful plan — the expectation is one or two turns, not an extended interview

The plan is a free-form working document, not a spec — checkboxes describe build steps, not product behaviour. See specs/plan/overview.md.
