description	Deliberate a feature or change in three locked rounds — functional requirements, then UI design with wireframes, then extras/quirks/out-of-the-box ideas. Each round asks the user clarifying questions via AskUserQuestion before proceeding. New functional scope at any point cascade-restarts the new piece through all three rounds and merges it into the locked plan. Use when the user invokes `/plan`, when the user is in plan mode and asks for a design/spec/feature breakdown, or when a non-trivial change needs structured deliberation before implementation.

/plan — Three-Round Locked Deliberation

A feature plan has three layers: what it does, how it looks, and the delightful extras. Cross-talk between them produces sloppy plans. This skill enforces a strict order: lock functional, then lock UI, then add extras. New functional scope discovered at any point cascades back through all three rounds for that new piece only, then merges into the locked plan.

Activation

Activate when any of:

• The user invokes /plan (with or without extra context).
• The user is in plan mode and asks for a design, spec, breakdown, or feature plan.
• A non-trivial change request would benefit from structured deliberation (multi-component features, UX-sensitive work, anything spanning >2 files).

Pre-flight: plan mode gate

Before Round 1, verify plan mode is active. If not:

This skill is meant to run in plan mode (read-only deliberation). Enter plan mode (Shift+Tab cycles to it) and re-invoke /plan <your context>.

Then stop. Do not proceed in edit/full-auto modes — the deliberation contract assumes no files will be touched mid-plan.

State you must track

Maintain these in your head (or in scratch) across the whole skill:

• LockedFunctional — bullet list of functional requirements confirmed so far.
• LockedUI — bullet list of UI decisions confirmed so far (with wireframe sketches).
• LockedExtras — list of delightful extras confirmed.
• CurrentRound — 1 (Functional), 2 (UI), or 3 (Extras).
• PendingNewPieces — queue of new functional requirements detected mid-flight that need their own cascade.

When a cascade fires, you snapshot CurrentRound, run the cascade for the new piece, merge results back into the Locked* sets, then resume from the snapshotted round.

Round 1 — Functional Requirements

Silently deliberate on what the user asked for. Pull out:

• Core capabilities the feature must have.
• Boundaries (what it does not do).
• Inputs, outputs, edge cases that change behavior.
• Ambiguities where multiple interpretations exist.

Then call AskUserQuestion with 1–4 questions that resolve the meaningful ambiguities. Each option should describe a concrete interpretation with its trade-off. Avoid asking the user to write prose — frame everything as concrete choices.

Tool reference: AskUserQuestion

Use AskUserQuestion(questions) to gather structured choices during Round 1, Round 2, Round 3, and any cascade. questions is an array of question objects:

• id: stable snake_case identifier.
• title: short user-facing label.
• text: the actual question.
• multiSelect: optional boolean for menus like LockedExtras.
• allowOther: optional boolean that permits an "Other" selection.
• allowAnnotation: optional boolean that permits free-text annotation alongside a selected option.
• options: array of { id, label, tradeoffs, description?, preview? }.

The return value is keyed by question id and contains selectedOptionIds, optional otherText, and optional annotations / freeText. Treat selected option ids as the locked choice. Treat otherText as a new option authored by the user; if it changes behavior, update LockedFunctional and trigger the Cascade rule. Treat annotations as refinements to the selected option; if an annotation adds behavior rather than clarifying wording or presentation, it also cascades.

When the user responds:

• Treat selected options as additions to LockedFunctional.
• If the user's free-text (the "Other" reply or annotation) adds new scope → see Cascade rule below.
• If the user only clarifies an existing item → update LockedFunctional and proceed.

Once questions are answered, do not ask for explicit confirmation. Silently move to Round 2.

Round 2 — UI Design

Now deliberate on how the feature presents to the user. Generate 1–3 candidate UI directions. Round 2 candidates may be full-layout wireframes when the whole surface is up for decision, or component-level candidates when only one area is ambiguous. Be explicit which level each candidate represents.

Call AskUserQuestion with options that carry markdown wireframe previews in the preview field. Wireframes are ASCII boxes:

┌─────────────────────────────────┐
│  Header  ·  filter ▾  ·  +new   │
├─────────────────────────────────┤
│ ▣ item                     ⋯    │
│ ▢ item                     ⋯    │
│ ▢ item                     ⋯    │
└─────────────────────────────────┘

Keep each preview readable in a chat-width column (~70 chars). Show real labels, real density, real affordances — not lorem ipsum.

Cover the meaningful axes (layout type, hierarchy of actions, empty/loading/error states, dense vs roomy) in at most 4 questions total. Don't waste a question on a decision that has one obvious answer.

When the user responds:

• Selected wireframes/options → LockedUI.
• If candidates were component-level, merge the selected components into LockedUI as integration decisions. The Final output still needs one composed/merged inline wireframe derived from LockedFunctional, LockedUI, and any selected LockedExtras.
• Free-text that implies new functional behavior (e.g. "add export button" implies an export flow) → see Cascade rule.
• Pure UI refinements stay in Round 2.

Silently proceed to Round 3.

Round 3 — Extras, Quirks, Out-of-the-Box

Now generate 4–8 candidate ideas the user didn't ask for but might love: micro-interactions, keyboard shortcuts, empty-state delight, power-user features, animations, accessibility wins, surprise affordances, anti-aesthetics-of-AI touches (favor warmth and specificity over generic monochrome polish).

Call AskUserQuestion with multiSelect: true for the menu of extras. Each option's description should be one sentence explaining the idea and one sentence on the cost/benefit.

Selected items → LockedExtras.

If the user adds a new functional idea in free-text → Cascade rule.

Cascade rule (the core contract)

A new functional requirement is any input — from the user OR self-detected from your own proposals — that adds, removes, or changes scope of the feature. Not a UI refinement. Not an extras pick. New behavior the system must perform.

When detected:

1. Snapshot the current round.
2. Queue the new piece in PendingNewPieces with a one-line description.
3. Announce briefly: "New functional piece detected: . Cascading it through R1→R2→R3 before resuming Round ."
4. Run a focused mini-cascade for that piece only:
   • R1 for new piece: AskUserQuestion scoped to just the new piece's functional ambiguities.
   • R2 for new piece: AskUserQuestion with wireframes scoped to just how this new piece integrates into the already-locked UI (do NOT redesign locked layouts — show how the new piece slots in).
   • R3 for new piece: AskUserQuestion with extras for this piece only.
5. Merge the results into the appropriate Locked* sets.
6. Resume from the snapshotted round.

Multiple cascades may stack. Process them depth-first; never lose the snapshot.

Self-detecting new functional scope

Before sending a UI option or an extra, ask yourself silently: does this option require behavior that isn't already in LockedFunctional? If yes, you have a choice:

• Drop the option (cleanest).
• Or, if it's genuinely a great idea, fire the cascade yourself before sending it. Don't sneak new functional scope into UI/extras questions.

Final output

After Round 3 completes with no pending cascades:

1. Print a tight consolidated plan in chat with three sections:
   • Functional — bulleted LockedFunctional.
   • UI — bulleted LockedUI with one inline wireframe of the final composed layout.
   • Extras — bulleted LockedExtras. Keep total under ~50 lines. No filler.
2. Call ExitPlanMode to formally request approval.

Tool reference: ExitPlanMode

Use ExitPlanMode(): void immediately after the Final output. It has no parameters and returns no value. Calling it signals that LockedFunctional, LockedUI, and LockedExtras are complete, including the final composed wireframe, and asks the user to approve leaving plan mode. Do not call it before all pending cascades are processed.

Anti-patterns (do not do)

• Asking the user to "describe what they want" in prose. Always frame as concrete options.
• Sending more than 4 questions in a single AskUserQuestion call (tool max).
• Slipping new functional behavior into UI or Extras rounds without cascading.
• Asking explicit "lock in? yes/no" questions between rounds — proceed silently unless interrupted.
• Re-litigating LockedFunctional during R2 or R3 unless a cascade explicitly opens that piece.
• Generic AI aesthetics in wireframes — no font-mono aesthetic apologies, no centered-everything, no purple gradients in mocked copy. Be specific and warm.
• Long preamble. The user invoked /plan; jump to Round 1.

Minimal example flow

User: /plan a markdown note app with tags

You: silent deliberation → AskUserQuestion (R1):

• Q1: "How should tags be created?" (inline #tag parsing / explicit tag field / both)
• Q2: "Search scope when filtering by tag?" (notes containing tag / notes tagged-only / both modes)
• Q3: "Multi-user or single-user?"

User selects + adds "and they sync to iCloud" (new functional scope).

You: "New piece detected: iCloud sync. Cascading." → R1-for-sync: conflict resolution? offline-first? → R2-for-sync: sync-status indicator placement? → R3-for-sync: optimistic UI? merge-conflict modal? Merge → resume Round 1.

… and so on through R2 and R3 of the main plan, then ExitPlanMode.
