Infographic Generator
Two dimensions: layout (information structure) × style (visual aesthetics). Freely combine any layout with any style.
User Input Tools
When this skill prompts the user, follow this tool-selection rule (priority order):
- Prefer built-in user-input tools exposed by the current agent runtime — e.g.,
AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
- Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
- Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.
Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.
Image Generation Tools
When this skill needs to render an image, resolve the backend in this order:
- Current-request override — if the user names a specific backend in the current message, use it.
- Saved preference — if
EXTEND.md sets preferred_image_backend to a backend available right now, use it.
- Auto-select (when the preference is
auto, unset, or the pinned backend isn't available):
- Codex (
imagegen) — first, inspect your available-skills / tool inventory. If a skill named imagegen is listed, you are running inside Codex and MUST use it: invoke via the Skill tool with skill: "imagegen", passing the saved prompt file's content (plus output path and aspect ratio per Codex imagegen's own args). Codex imagegen is the official raster backend in that runtime and outranks any non-native skill (e.g., baoyu-image-gen) unless the user has explicitly pinned a different preferred_image_backend.
- Codex via
codex exec () — if the current runtime exposes no native skill but the CLI is on with an active , route through (preferred), or — if baoyu-image-gen is unavailable — invoke the bundled wrapper directly. Details, parameters, and the runtime-discovery procedure live in — load that file only when this branch is selected.
- If none are available, tell the user and ask how to proceed.
⛔ Never substitute SVG, HTML, canvas, or other code-based rendering for raster image generation. Codex imagegen's own description says it should be used "when the output should be a bitmap asset rather than repo-native code or vector." If you cannot resolve a raster backend via step 3, fall through to step 4 and ask the user — do not silently emit SVG, write inline <svg> markup, or produce HTML/CSS art as a substitute. This applies even if the article/section seems "diagram-like": the consumer skill calling this rule has already decided that a raster image is what it needs.
⛔ Never repair rendered text by painting over a generated bitmap. Do not use ImageMagick, Pillow, Canvas, SVG, HTML/CSS, OCR scripts, or any other programmatic overlay to cover, rewrite, erase, stroke, or replace labels, headings, callouts, data values, or any other text inside an already generated infographic. If text is wrong or unclear, regenerate from a corrected prompt, switch to a layout with less on-image text, or ask the user which imperfect candidate to keep.
Setting preferred_image_backend: ask forces the step-3 prompt every run regardless of available backends. Users change the pinned backend via the ## Changing Preferences section below.
Prompt file requirement (hard): write each image's full, final prompt to a standalone file under prompts/ (naming: NN-{type}-[slug].md) BEFORE invoking any backend. The backend receives the prompt file (or its content); the file is the reproducibility record and lets you switch backends without regenerating prompts.
Concrete tool names (imagegen, GenerateImage, image_generate, baoyu-image-gen) above are examples — substitute the local equivalents under the same rule.
Reference Images
Users may supply reference images to guide style, palette, composition, or subject.
Intake: Accept via --ref <files...> or when the user provides file paths / pastes images in conversation.
- File path(s) → copy to
refs/NN-ref-{slug}.{ext} alongside the output
- Pasted image with no path → ask the user for the path (per the User Input Tools rule above), or extract style traits verbally as a text fallback
- No reference → skip this section
Usage modes (per reference):
| Usage | Effect |
|---|
direct | Pass the file to the backend as a reference image |
style | Extract style traits (line treatment, texture, mood) and append to the prompt body |
palette | Extract hex colors from the image and append to the prompt body |
Record in prompts/infographic.md frontmatter when refs exist:
references:
- ref_id: 01
filename: 01-ref-brand.png
usage: direct
At generation time:
- Verify each referenced file exists on disk
- If
usage: direct AND the chosen backend accepts reference images (e.g., baoyu-image-gen via --ref) → pass the file via the backend's ref parameter
- Otherwise → embed extracted
style/palette traits in the prompt text
Confirmation Policy
Default behavior: confirm before generation.
- Treat explicit skill invocation, a file path, a matched keyword shortcut,
EXTEND.md defaults, and the documented default combination as recommendation inputs only. None of them authorizes skipping confirmation.
- Do not start Step 5 or Step 6 until the user confirms the combination/aspect/language/backend choices.
- Skip confirmation only when the current request explicitly says to do so, for example:
--no-confirm, "直接生成", "不用确认", "跳过确认", "按默认出图", or equivalent wording.
- If confirmation is skipped explicitly, state the assumed combination/aspect/language/backend in the next user-facing update before generating.

Keyword Shortcuts
When the user's input contains these keywords, use the mapped layout as the leading Step 3 recommendation and promote the listed styles to the top of the Step 3 list. Skip content-based layout inference for matched keywords. Append any Prompt Notes to the Step 5 prompt.
| User Keyword | Layout | Recommended Styles | Default Aspect | Prompt Notes |
|---|
| 高密度信息大图 / high-density-info | dense-modules | morandi-journal, pop-laboratory, retro-pop-grid, retro-popup-pop | portrait | — |
| 信息图 / infographic | bento-grid | craft-handmade |
Output Structure

Core Principles
- Preserve source data faithfully—no summarization or rephrasing (but strip any credentials, API keys, tokens, or secrets before including in outputs)
- Define learning objectives before structuring content
- Structure for visual communication (headlines, labels, visual elements)
Workflow
Step 1: Setup & Analyze
1.1 Load Preferences (EXTEND.md)
Check EXTEND.md in priority order — the first one found wins:
| Priority | Path | Scope |
|---|
| 1 | .baoyu-skills/baoyu-infographic/EXTEND.md | Project |
| 2 | ${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-infographic/EXTEND.md | XDG |
| 3 | $HOME/.baoyu-skills/baoyu-infographic/EXTEND.md | User home |
| Result | Action |
|---|
| Found | Read, parse, display a one-line summary |
| Not found | Ask the user with AskUserQuestion (see references/config/first-time-setup.md) |
EXTEND.md supports: preferred layout/style, default aspect ratio, language preference, preferred image backend, custom style definitions.
Schema: references/config/preferences-schema.md
1.2 Analyze Content → analysis.md
- Save source content (file path or paste →
source.md)
- Backup rule: If
source.md exists, rename to source-backup-YYYYMMDD-HHMMSS.md
- Analyze: topic, data type, complexity, tone, audience
- Detect source language and user language
- Extract design instructions from user input
- Save analysis
- Backup rule: If
analysis.md exists, rename to analysis-backup-YYYYMMDD-HHMMSS.md
See references/analysis-framework.md for detailed format.
Step 2: Generate Structured Content → structured-content.md
Transform content into infographic structure:
- Title and learning objectives
- Sections with: key concept, content (verbatim), visual element, text labels
- Data points (all statistics/quotes copied exactly)
- Design instructions from user
Rules: Markdown only. No new information. Preserve data faithfully. Strip any credentials or secrets from output.
See references/structured-content-template.md for detailed format.
Step 3: Recommend Combinations
3.1 Check Keyword Shortcuts first: If user input matches a keyword from the Keyword Shortcuts table, use the associated layout as the leading recommendation and prioritize associated styles as top recommendations. Skip content-based layout inference.
3.2 Otherwise, recommend 3-5 layout×style combinations based on:
- Data structure → matching layout
- Content tone → matching style
- Audience expectations
- User design instructions
Step 4: Confirm Options
Hard gate: this step is mandatory per the Confirmation Policy — Steps 5–6 cannot start until the user confirms here (or explicitly opts out with --no-confirm / equivalent in the current request).
Ask the user to confirm the questions below following the User Input Tools rule at the top of this file (batch into one call if the runtime supports multiple questions; otherwise ask one at a time in priority order).
| Priority | Question | When | Options |
|---|
| 1 | Combination | Always | 3+ layout×style combos with rationale |
| 2 | Aspect | Always | Named presets (landscape/portrait/square) or custom W:H ratio (e.g., 3:4, 4:3, 2.35:1) |
| 3 | Language | Only if source ≠ user language | Language for text content |
| 4 | Image Backend | Only if step 3 of the ## Image Generation Tools rule needs to ask (no runtime-native tool AND multiple non-native backends, OR preferred_image_backend: ask) | Available backends |
Step 5: Generate Prompt → prompts/infographic.md
Backup rule: If prompts/infographic.md exists, rename to prompts/infographic-backup-YYYYMMDD-HHMMSS.md
Combine:
- Layout definition from
references/layouts/<layout>.md
- Style definition from
references/styles/<style>.md
- Base template from
references/base-prompt.md
- Structured content from Step 2
- All text in confirmed language
Aspect ratio resolution for {{ASPECT_RATIO}}:
- Named presets → ratio string: landscape→
16:9, portrait→9:16, square→1:1
- Custom W:H ratios → use as-is (e.g.,
3:4, 4:3, 2.35:1)
Step 6: Generate Image
- Resolve the backend per the
## Image Generation Tools rule at the top of this file.
- Ensure the full final prompt is persisted at
prompts/infographic.md (already written in Step 5) BEFORE invoking the backend — the file is the reproducibility record.
- Check for existing file: Before generating, check if
infographic.png exists
- If exists: Rename to
infographic-backup-YYYYMMDD-HHMMSS.png
- Call the chosen backend with the prompt file and output path.
codex-imagegen invocation: when the rule resolves to codex-imagegen, see references/codex-imagegen.md for the invocation contract (preferred baoyu-image-gen --provider codex-cli path, runtime wrapper discovery, parameter notes, stdout schema, batch semantics).
- On failure, auto-retry once
Text correction policy:
- If labels, headings, callouts, data values, or any other rendered text is misspelled, garbled, hard to read, or visually weak, do not patch the bitmap with code.
- For text-correction regenerations, write a new prompt file and a new output path so the flawed candidate is preserved for comparison.
- Post-processing is limited to crop, resize, compression, or format conversion that does not alter text or the main composition.
Step 7: Output Summary
Report: topic, layout, style, aspect, language, image backend, output path, files created.

Changing Preferences
EXTEND.md lives at the first matching path in Step 1.1. Three ways to change it:
- Edit directly — open EXTEND.md and change fields. Full schema:
references/config/preferences-schema.md.
- Reconfigure interactively — delete EXTEND.md (or ask "reconfigure baoyu-infographic preferences" / "重新配置"). The next run re-triggers first-time setup.
- Common one-line edits:
preferred_image_backend: auto — default; runtime-native tool wins, falls back to the only installed backend, asks only if multiple non-native are present.preferred_image_backend: codex-imagegen — pin to Codex's built-in.preferred_image_backend: baoyu-image-gen — pin to the baoyu-image-gen skill.preferred_image_backend: ask — confirm backend every run.preferred_layout: dense-modules, preferred_style: morandi-journal, preferred_aspect: portrait, — shift the Step-3 recommendations and Step-4 defaults (per , these never bypass Step 4).
