# Feature planning (interactive)

Load the **`feature-planning-core`** skill (`game-sdlc:feature-planning-core` when installed as a

plugin) and follow it in **interactive mode**: the owner answers every round.

What this mode adds to the core:

## Make answering cheap

- If a multiple-choice question tool is available (such as `AskUserQuestion`), use it: up to four

questions per call, your recommendation as the first option and labelled "(Recommended)". Put

anything longer — the walkthrough, a sketch — in the message before the questions.

- Otherwise write the round as numbered markdown, each with "→ Recommended: …", so the owner can

answer "yes to all except 2".

- Keep each round to the frontier. If a round would run past about six questions, split it by what

the owner cares about most first (what the player sees), then the rest.

- The owner reads the ledger, not the plan. Write every answer into the ledger as it's given, so the

approval at the end is a re-read, not a reconstruction.

## Before asking for approval

1. Show the ledger's decisions table, the walkthrough and the sketches — the three things the owner

will actually judge.

2. For a big plan, report the two-way review in two lines: decisions missing from the plan (and how

they were fixed), and invented decisions found (and the questions they became).

3. Ask for approval of the **ledger** explicitly, as one yes/no question. Anything other than a clear

yes keeps the state at READY FOR APPROVAL.

## After approval

Offer the hand-off from the core skill's last step: record rulings, create the epic with
