name	ppt-slide-planner
description	Plan precise slide-by-slide PPT structures from a topic, text content, requirements, or uploaded-material summaries, and prepare a file-generator-ready PPTX payload for downstream generation. Use when the user asks for PPT planning, PowerPoint outline, slide planning, page-by-page PPT requirements, presentation storyboard, report deck structure, pitch deck outline, training deck plan, proposal slides, project report slides, business review slides, or when the user asks to first create a precise outline before generating a PPT file. This skill is the planning and layout layer, not the PPTX file generator.
when_to_use	Use this skill when the user wants a PowerPoint/PPTX deck planned from a topic, notes, copied text, summarized source material, or agent-prepared outline; use it for presentation planning, slide-by-slide content design, page splitting, layout selection, brand styling, media placeholder planning, and preparing structured requirements for the file-generator skill.

PPT Slide Planner Skill

Use this skill to turn a user's topic, text content, requirements, or source-material summary into a strict per-slide construction plan. This skill plans the PPT only; the actual editable PPTX file is produced by the separate file-generator skill.

This skill must not call PPTX generation tools, render PPTX files by itself, implement fallback renderers, or bypass file-generator. When the user asks for a PPT file, first produce the planning output and then route that output to the file-generator skill, which owns generate_pptx.

Workflow

1. Determine whether the user provided enough context: topic, audience, use case, slide count or duration, style or brand requirements, and source content.
2. If the topic, source content, audience, or use case is too unclear to produce a reliable deck, call request_user_input before planning. For slide count, style, and layout preferences, make conservative defaults when the content is otherwise clear and state the assumptions.
3. Read deck-brief.md and produce a concise internal deck brief.
4. Read slide-plan-contract.md and create a slide-by-slide plan. Every slide must have exact title text, body text, page objective, layout, element list, and media placeholder requirements.
5. Read slide-layout-contract.md and select a concrete layout for each slide.
6. Read media-placeholder-contract.md when the deck needs image, chart, diagram, or video placeholder areas.
7. Read pptx-payload-contract.md and convert the slide plan into one complete strict JSON object that can be passed later as file-generator/generate_pptx.presentation.
8. Read quality-check.md and self-check every slide before handoff. If any text element may overflow, increase h, reduce text, add line breaks, or split the content before preparing the payload.
9. Before handoff, verify presentation starts with {, ends with }, contains only strict JSON, has balanced braces/brackets, closes the slides array, and contains no Markdown fences, comments, prose, trailing commas, or unquoted visible text.
10. Return or hand off the strict slide plan and PPTX payload to the file-generator skill when file output is required. Do not call generate_pptx from this skill.
11. In the final answer, briefly mention that the PPT plan is ready for file generation and list any important assumptions. Do not paste the full presentation JSON unless the user explicitly asks for it.

Clarification Workflow

When a blocking decision is missing or ambiguous, call request_user_input instead of writing a plain clarification message. Do not stop for every optional preference.

Ask about:

• Presentation topic when the topic is not clear.
• Audience or use case when the intended communication goal is unclear.
• Slide count or presentation duration only when the user explicitly requires a controlled length and the target size is unclear. Otherwise choose a compact slide count from the content volume and state the assumption.
• Style, template, or brand only when the user requires a specific template or corporate brand but does not provide enough brand rules. Otherwise use a neutral business style and state the assumption.
• Whether image, chart, diagram, or video placeholders are needed when the content implies visual materials.

After calling request_user_input, stop the turn and wait for the user's answer. Do not start PPTX file generation in the same turn.

References

Read references only when needed, but always read pptx-payload-contract.md and quality-check.md before preparing a file-generator handoff payload.

Task	Read reference
Build the deck brief from topic, audience, source content, and requirements	deck-brief.md
Create strict per-slide plans with exact text and element requirements	slide-plan-contract.md
Choose concrete slide layouts and coordinates	slide-layout-contract.md
Reserve image, chart, diagram, or video placeholder areas	media-placeholder-contract.md
Convert the slide plan into file-generator generate_pptx.presentation JSON	pptx-payload-contract.md
Validate text density, overlap, bounds, style consistency, and output readiness	quality-check.md

Output Contract

Before handing off to file-generator, internally prepare:

• deck_brief: theme, audience, scenario, slide count, style, language, brand rules, and source constraints.
• slide_plan: one object per slide with exact title, objective, layout, elements, text, coordinates, style, and placeholder descriptions.
• pptx_payload: valid strict file-generator/generate_pptx.presentation JSON string.

The downstream file-generator/generate_pptx call must pass:

• presentation: strict JSON string with layout, language, default_style, and slides.
• filename: concise ASCII filename without extension.
• title: optional title hint.
• lifecycle: persistent unless the user asks for temporary output.

Constraints

• Do not call generate_pptx from this skill. Each slide must have a strict slide plan first, then the payload is handed to file-generator.
• Do not generate PPTX files directly from this skill. Always hand the final strict presentation JSON to the file-generator skill.
• Do not implement or assume a fallback PPTX renderer in the planning skill. If file generation infrastructure is unavailable, report that file generation must be retried through file-generator after the dependency is available.
• Do not invent facts, metrics, product claims, customer names, or conclusions not provided or clearly implied.
• Do not use unsupported PPTX features: animations, transitions, speaker notes, comments, slide masters, theme inheritance, real charts, embedded media, external images, or editing existing PPTX files.
• If image, chart, diagram, or video content is requested, create a visible placeholder using shape and text; do not claim the media is embedded.
• Do not pass Markdown, HTML, comments, prose, partial objects, or unquoted text as presentation; pass strict valid PPTX JSON only.
• Do not put raw multi-line text inside JSON string values. Encode line breaks as \n.
• Do not use trailing commas or single quotes in JSON.
• Do not prepare a truncated or partially closed JSON object. Balance {}, [], close slides, and keep the final non-space character as }.
• Keep generated PPTX JSON compact. Prefer under 10,000 characters, no more than 8 slides, and no more than 10 elements per slide unless the user explicitly requires more.
• If downstream file generation reports unexpected EOF, rebuild a shorter complete JSON payload from the slide plan before handing off again.
• Split dense content into more slides. Do not shrink text until it becomes unreadable.
• Do not prepare a handoff payload with a body text element over 10 estimated wrapped lines or over 0.75 * h.
• Do not prepare a handoff payload with a normal body text element above 4.0 inches estimated height unless the user explicitly requested a dense appendix slide.
• Never prepare a single body text element above 4.5 inches estimated height; split it into continuation slides.
• For near-full-height body boxes such as h=5.0 or h=5.3, do not increase height after a fit failure. Split the text.
• For local text boxes in two-column, comparison-card, visual-placeholder, process-step, sidebar, or any body box with w < 7.0 or h < 4.2, keep estimated height at or below min(2.8, h * 0.70).
• For small cards with h <= 3.5, keep estimated height at or below h * 0.65; do not fix overflow by only increasing the local box height.
• For narrow columns with w <= 5.8, use at most 3 bullets or about 90 Chinese characters / 220 English characters per text element.
• If downstream file generation reports text does not fit, split the reported slide/element into continuation slides before handing off a new payload.
• For title_body body boxes at h=5.3, overflow must be fixed by splitting the slide, not by increasing height.
• Do not use small title boxes for long titles. A 36-44 pt title that may wrap to two lines needs at least h=1.6; a one-line title needs at least h=0.85.
• For every title/text element, reserve height from text length and font size before handoff; set h to at least estimated_height * 1.25.
• Do not prepare a handoff payload when estimated text height is within 0.2 inches of h; increase h by at least 0.3 inches or shorten/split text first.
• Do not use h < 1.15 for 16-24 pt subtitle, label, or metadata text unless it is one short line with estimate under 0.65.
• Never rely on the renderer to shrink overflowing text.
• Keep readable text and tables within slide bounds and non-overlapping.
• Use consistent font, colors, title hierarchy, and spacing across the deck.
• If the user's requirements exceed current PPTX support, state the limitation and prepare the closest supported editable static deck only when it still satisfies the request.
