description: "Use this skill when the user wants a .pptx with smooth cross-slide animation — PowerPoint Morph transitions, Keynote-style continuous motion, shapes that grow / move / rotate as the slide advances. Trigger on: 'morph', 'morph transition', 'smooth transition', 'continuous animation across slides', 'Keynote-style transition', 'animated slide sequence', 'shape continuity across slides'. Output is a single .pptx. This skill is a scene layer on top of officecli-pptx — inherits every pptx v2 rule (visual floor, grid, palettes, connector canon, Delivery Gate 1–5a). DO NOT invoke for a generic deck, pitch deck, or board review without cross-slide motion — route those to officecli-pptx base or officecli-pitch-deck."

OfficeCLI Morph-PPT Skill

**This skill is a scene layer on top of `officecli-pptx`.** Every pptx hard rule — visual delivery floor (title ≥ 36pt / body ≥ 18pt / title ≥ 2× body), 12-column grid on 33.87×19.05cm, canonical palettes, chart-choice decision table, connector canon, shell escape, resident + batch, Delivery Gate 1–5a — is inherited, not re-taught. This file adds only what **Morph** needs on top: cross-slide shape-name binding, Scene Actors vs content prefixing, ghost discipline, `transition=morph` CLI quirks, 52-style visual library lookup, and a morph-specific fresh-eyes Gate 5b extension.

When the pptx base rules cover it, the text here says `→ see pptx v2 §X`. Read `skills/officecli-pptx/SKILL.md` first if you have not.

Setup

If `officecli` is missing:

• **macOS / Linux**: `curl -fsSL https://d.officecli.ai/install.sh | bash`
• **Windows (PowerShell)**: `irm https://d.officecli.ai/install.ps1 | iex`

Verify with `officecli --version` (open a new terminal if PATH hasn't picked up). If install fails, download a binary from https://github.com/iOfficeAI/OfficeCLI/releases.

⚠️ Help-First Rule

**This skill teaches the Morph workflow — when shape names must match, when to ghost, when the CLI auto-prefixes — not every command flag.** When a prop name, enum, or preset is uncertain, consult help BEFORE guessing.

officecli help pptx slide           # authoritative for: transition, advanceTime, advanceClick, background
officecli help pptx shape           # name, preset, x/y/width/height, fill, rotation, opacity, animation
officecli help pptx animation       # preset + trigger + duration values
officecli help pptx <element> --json  # machine-readable schema

Help reflects the installed CLI version. When skill and help disagree, **help wins.** Every `--prop X=` in this file is grep-verified against `officecli help pptx <element>`. Specific confirmations: `transition=morph` is a listed value on `slide`; `advanceTime` / `advanceClick` are valid. **There is NO standalone `transition` element** — `officecli help pptx transition` returns error. Sub-props such as `duration` / `delay` / `easing` for the transition itself are **not exposed on `slide`** — see §Known Issues for the raw-set path if you need them.

Mental Model & Inheritance

**Inherits pptx v2.** You should have read `skills/officecli-pptx/SKILL.md` first. This skill assumes you know how to: add slides + shapes + charts + connectors; address by `@name=` / `@id=`; quote paths; use `batch` heredocs; use `tailEnd=triangle` on flow connectors; run the Delivery Gate 1–5a; attribute `[AGENT-ERROR]` vs `[RENDERER-BUG]` vs `[SKILL gap]`. If any of those are unfamiliar, read pptx v2 first.

**Inherited from pptx v2 (do NOT re-teach):**

• Visual delivery floor — title ≥ 36pt / body ≥ 18pt / title ≥ 2× body, cover-richness, contrast floor, no `\$\t\n` literals, ≤ 1 animation per slide / ≤ 600ms.
• Grid math — 33.87 × 19.05cm, edge margin ≥ 1.27cm, inter-block gap ≥ 0.76cm, ≥ 20% negative space. For N-card grids: `col = (33.87 − 2·margin − (N−1)·gap) / N`.
• Four canonical palettes (Executive navy / Forest & moss / Warm terracotta / Charcoal minimal) — morph decks may pick a different mood from `reference/styles/`, but contrast rules still apply.
• Chart-choice table — column vs bar vs line vs pie vs scatter vs large-text KPI; `> 3 series + > 8 categories` = split.
• Connector canon — `shape=straight|elbow|curve`, `@id=` for from/to (C-P-6), `tailEnd=triangle` on every flow.
• Shell escape 3-layer — `$` single-quoted, heredocs for batch, `<a:br/>` for real newlines.
• Resident mode + batch ≤ 12 ops, `<<'EOF'` single-quoted delimiter.
• Delivery Gate 1-5a (schema, token grep, hyperlink rPr, slide-order, dark-on-dark) — every gate prints OK before declaring done.
• Known Issues C-P-1..7 (hyperlink rPr, chart spPr warning, animation duration readback, animation remove, connector enum, connector `@name=`, chart color renderer normalization).
• Attribution triage — `[AGENT-ERROR]` vs `[RENDERER-BUG]` vs `[SKILL gap]`.

**Morph identity — what this skill owns (delta on top of pptx v2):**

• **Cross-slide shape-name binding.** PowerPoint's Morph engine pairs shapes by **identical `name=`** across adjacent slides and interpolates their position / size / rotation / fill / opacity. No matching name ⇒ no animation, silent fade. This is a workflow discipline, not a CLI feature.
• **Namespace prefixes:** `!!scene-*` (persistent decoration, never ghosted) / `!!actor-*` (content that evolves then exits) / `#sN-*` (per-slide content, ghosted on slide N+1). Plan the names BEFORE you `add`.
• **Ghost position `x=36cm`** (off the right edge of the 33.87cm canvas). Never delete a `!!`-prefixed shape — move it off-canvas so the morph exit animation still plays.
• **`transition=morph` auto-prefix quirk.** The CLI auto-prepends `!!` to every shape on a morph slide, which silently breaks `@name=` path selectors. Use `/slide[N]/shape[K]` index paths after morph is set. See §Known Issues.
• **Adjacent-slide spatial variety.** Displacement ≥ 5cm or rotation ≥ 15° between pairs — otherwise morph interpolates nothing visible.
• **Renderer reality.** Morph renders in PowerPoint 365 / Keynote / WPS. Li
