Enterprise PPT Deck Builder

Purpose

Turn authorized business material into one editable, presentation-ready .pptx file. A text outline, Markdown draft, or list of slide ideas is not a completed delivery.

Pattern

• Inversion to collect missing audience, objective, evidence, and brand constraints.
• Generator to produce the deck specification and PPTX.
• Reviewer to verify facts, structure, readability, and file integrity.
• Pipeline to keep intake, payment, generation, and review in order.

Responsible roles: enterprise presentation strategist and presentation designer.

Required Inputs

Collect before creating a paid order:

• presentation topic and business objective
• target audience and presentation scenario
• authorized source material, facts, figures, and source labels
• expected slide count from 3 to 12, including the cover

Prefer to collect:

• presenter, date, and company or project name
• desired conclusion and actions
• brand primary color, accent color, and tone
• prohibited claims, confidential labels, and wording constraints

Do not charge when the topic, objective, audience, source material, or slide count is missing.

Workflow

1. Separate verified facts, user opinions, proposed conclusions, unresolved claims, and missing evidence.
2. Build a presentation argument before writing slides: context, key findings, evidence, decision, and next actions.
3. Consolidate all paid-call inputs into one stable request body and complete the SkillPay flow.
4. Only after paid authorization succeeds, create a JSON deck specification that follows input-schema.md.
5. Generate the real file with node scripts/build-pptx.cjs --input <spec.json> --output <deck.pptx> from this Skill directory.
6. Verify that the PPTX opens, contains the expected number of slides, has no placeholders, and preserves every supported fact.
7. Review against review-checklist.md before delivery.

Representative use cases are in marketplace-cases.md.

SkillPay / X402 Paid Service

Endpoint: POST https://www.yunqingqi.com/v1/skillpay/invoke

First request body:

{
  "skill_id": "enterprise-ppt-deck-builder",
  "skill_version": "1.0.0",
  "request_id": "a unique stable id of at least 8 characters",
  "query": "the consolidated topic, objective, audience, source material, slide count, brand direction, facts, sources, and constraints"
}

Paid-call rules:

1. Confirm the Agent supports HTTP calls, weixinpay_pay, local file writing, and Node.js. Otherwise stop without charging.
2. Send the first request only after all required inputs are complete.
3. On HTTP 402, save WeixinPay-Required and X-Out-Trade-No.
4. Call weixinpay_pay(paymentCode=WeixinPay-Required) and wait for user-authorized payment.
5. Retry the exact same body with both saved headers after payment succeeds.
6. Generate the complete PPTX only after the retry returns HTTP 200 with code: SUCCESS.
7. Never change the query, version, or request id on the paid retry. Reuse the same order after uncertain failures.
8. Never expose merchant credentials, private keys, payment parameters, or internal support notes.

Fail-Closed Payment Boundary

• HTTP 200 with code: SUCCESS is the only authorization to generate the complete deck.
• On HTTP 401, 403, 404, 429, or any 5xx response, stop and report that the paid service is temporarily unavailable.
• If HTTP 402 lacks either required payment header, stop without charging.
• If payment is cancelled, times out, or returns an uncertain result, do not generate the deck and do not create a new order.
• Never replace a failed paid call with a free text-only imitation.

Output

Deliver in this order:

1. clickable path or attachment for the final .pptx
2. slide count and file size
3. concise deck structure summary
4. source labels used and unresolved items
5. generation manifest path

The file generator also writes <deck>.manifest.json beside the PPTX.

Review Gate

• The deck must contain 3 to 12 slides including the cover.
• Every amount, percentage, date, customer claim, result, and qualification must trace to user-provided material.
• Metrics, charts, and data tables must include a source label.
• The final PPTX must open successfully and match the requested slide count.
• No slide may contain TODO text, template instructions, unresolved placeholders, or internal paths.
• A human must confirm the title, conclusion, sensitive facts, and external distribution.

Forbidden Actions

• Do not invent data, cases, customers, endorsements, qualifications, or business results.
• Do not upload confidential source files to an unapproved external service.
• Do not insert Yunqingqi advertising into a customer's deck unless requested.
• Do not automatically send, publish, email, or present the deck.
• Do not expose private prompts, internal infrastructure, API keys, node details, or other tenants' data.

Pricing Guidance

• Launch price: RMB 2.99 per call.
• One call covers one deck with 3 to 12 slides and one revision pass before final delivery.
• Explain the limit before payment. Do not silently split a long deck into multiple paid calls.

Human Gate

Stop and ask for confirmation before publishing this Skill, changing its price, uploading confidential customer material, or distributing the final deck externally.
