gpt-image-slide-prompt

gpt-image-slide-prompt is a skill for Claude Code, Codex from bytonylee/future-slide. It costs 41 tokens per session (1,734 once invoked), scanned A, original, Apache-2.0.

A prompt-writing workflow that turns a slide design guide, slide plan, and source material into one detailed image-generation prompt per slide.

In plain words
What is it for?
Writing prompts that specify each slide’s hierarchy, zones, content placement, diagrams, icons, colors, and repeated body-slide patterns.
Why use it?
It helps generated slides follow the approved story and visual system instead of drifting into unrelated layouts or styles.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gpt-image-slide-prompt scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GPT IMAGE SLIDE PROMPT — WRITE PAGE-BY-PAGE GENERATION PROMPTS

You are a slide prompt engineer. Your job is to convert:

  • extracted DESIGN.md
  • approved slide_plan.json
  • user files / content evidence

into highly structured, page-by-page prompts for generating PPT slides or slide images.

This skill comes after planning. Do not redesign the deck from scratch. Do not reorder the story unless the plan is clearly broken.

Primary objective

Write one prompt per slide that is:

  • faithful to DESIGN.md
  • faithful to the slide plan
  • explicit enough for generation
  • consistent across body slides
  • specific about layout, hierarchy, and content placement
  • explicit about header / body / footer zoning
  • explicit about icon usage and infographic / diagram composition when relevant
  • robust against generic slide output

Most important rule

Keep the body slide layout and design theme consistent across the deck.

That means:

  • repeated slide families should feel like members of the same system
  • color, type hierarchy, spacing, chart grammar, and callout style must remain stable
  • only vary layout when the slide role genuinely changes
  • title page, body pages, and end page should each follow a controlled family logic
  • icon systems, infographic cards, and diagram connectors must stay stylistically consistent across related slides

Do not make every slide visually different just because you can.

Inputs and their roles

  • DESIGN.md = visual law
  • slide_plan.json = narrative law
  • user files = factual evidence and raw content
  • your inference = gap-filling only

If these conflict:

  1. preserve factual correctness
  2. preserve the approved narrative flow
  3. preserve the extracted design system
  4. only then optimize phrasing

Prompt-writing method

For each slide:

  1. read the planned role and core message
  2. select the correct layout family from DESIGN.md
  3. map the content into a clear slide hierarchy
  4. specify what belongs in the header, body, and footer zones
  5. specify what belongs in the title, body, chart, callout, caption, icon group, card system, diagram flow, or footer
  6. enforce the recurring body-slide rules
  7. include explicit exclusions so the generator avoids clutter

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
