Baoyu Image Cards

Generates infographic image card series with 12 visual styles, 8 layouts, and 3 color palettes. Breaks content into 1-10 cartoon-style image cards optimized...

Security Scan

The skill appears to implement an image-card generator as described, but its runtime instructions require writing preference and prompt files to the user's project/home directories and enforce a blocking first-time setup even though the metadata declares no config paths — this mismatch and the mandatory filesystem writes warrant caution.

Purpose & Capability

The described purpose (generate image card series) aligns with the instructions (styles, palettes, image backend selection). However, the skill metadata declares no required config paths or environment variables, while the SKILL.md and references explicitly require creating and persisting an EXTEND.md in .baoyu-skills/ or ~/.baoyu-skills/ and writing prompt files under prompts/. That discrepancy between declared requirements and actual file writes is notable.

Instruction Scope

Runtime instructions mandate a blocking first-time setup (must complete before any other steps), require creating EXTEND.md saved to project or user home, and require writing each image prompt to prompts/ before invoking any image backend. These steps cause persistent writes of user content and preferences and could store potentially sensitive prompt/user-provided content. There are no instructions to sanitize or prompt for explicit filesystem permission beyond the setup flow; the skill does not contact external endpoints or request secrets.

Install Mechanism

No install spec and no code files — instruction-only skill. This minimizes supply-chain risk because nothing is downloaded or executed locally beyond the agent following the SKILL.md prose.

Credentials

The skill requests no environment variables or credentials (consistent with no external APIs). Still, it expects to read/write preference/config files in project or home directories and to create prompt files; these filesystem actions are not declared in the metadata (no required config paths listed), an inconsistency that reduces transparency about what the skill will access.

Persistence & Privilege

Although not marked always:true, the skill requests persistent presence via writing EXTEND.md (user or project scope) and storing prompts and outline files. The mandatory blocking setup that must complete before other steps increases the chance of unwanted persistent changes. The skill does not request other skills' configs, but it will create and reuse files in the user's filesystem.

What to consider before installing

What to consider before installing: - The skill is instruction-only and does not download code or ask for API keys, which reduces remote-execution risk. However, it will create and persist files on disk: an EXTEND.md preference file (either in the project at .baoyu-skills/baoyu-xhs-images/ or in the user's home at ~/.baoyu-skills/baoyu-xhs-images/) and per-image prompt files under a prompts/ folder. Decide whether you are comfortable with the skill writing configuration and prompt content to those locations. - The SKILL.md enforces a blocking first-time setup flow that must complete before other operations; this means the agent will prompt to save preferences and then immediately write files. If you want to review what it would write first, avoid auto-confirm flags like --yes and answer setup prompts cautiously. - Prompts saved to disk may contain sensitive or private data (e.g., proprietary copy, user-supplied details). If that is a concern, run the skill in a sandboxed workspace or inspect the written files after setup and before generating images, or modify the save location to a project-limited directory rather than your home directory. - The metadata does not declare these config paths or filesystem actions; that mismatch could be an oversight but reduces transparency. Ask the skill author (or check the repository) whether you can opt out of persistent saving or change the default save location. - If you need stronger assurance, request that the skill be updated to: (1) explicitly declare required config paths in metadata, (2) make the initial setup optional (not blocking), and (3) prompt for explicit write permission with the exact paths before creating files. These changes would raise confidence in the skill's behavior.

Image Card Series Generator

Break down complex content into eye-catching image card series with multiple style options.

User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
2. 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.
3. 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:

1. Current-request override — if the user names a specific backend in the current message, use it.
2. Saved preference — if EXTEND.md sets preferred_image_backend to a backend available right now, use it.
3. Auto-select (when the preference is auto, unset, or the pinned backend isn't available):
   • If the current runtime exposes a native image tool (e.g., Codex imagegen, Hermes image_generate), use it. Runtime-native tools are preferred by default — agents that know their own tool inventory should surface the native one here.
   • Otherwise, if exactly one non-native backend is installed (e.g., baoyu-imagine), use it.
   • Otherwise (multiple non-native backends with no runtime-native tool), ask the user once — batch with any other initial questions.
4. If none are available, tell the user and ask how to proceed.

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 file is the reproducibility record and lets you switch backends without regenerating prompts.

Concrete tool names (imagegen, image_generate, baoyu-imagine) above are examples — substitute the local equivalents under the same rule.

Confirmation Policy

Default behavior: confirm before generation.

• Treat explicit skill invocation, a file path, matched signals/presets, and EXTEND.md defaults as recommendation inputs only. None of them authorizes skipping confirmation.
• Do not start Step 3 until the user completes Step 2.
• Skip confirmation only when the current request explicitly says to do so, for example: --yes, "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 strategy / style / layout / palette / count / backend in the next user-facing update before generating.

Language

Respond in the user's language across questions, progress, errors, and completion summary. Keep technical tokens (style names, file paths, code) in English.

Options

Option	Description
--style <name>	Visual style (see Styles below)
--layout <name>	Information layout (see Layouts below)
--palette <name>	Color override: macaron / warm / neon
--preset <name>	Style + layout + optional palette shorthand (see Presets below; per-preset prompt fragments in references/style-presets.md)
--ref <files...>	Reference images applied to image 1 as the series anchor
--yes	Non-interactive: skip all confirmations, use EXTEND.md or built-in defaults, auto-confirm recommended plan (Path A)

Dimensions

Three independent knobs combine freely:

Dimension	Controls	Options
Style	Visual aesthetics (lines, decorations, rendering)	12 styles (see Styles below)
Layout	Information structure (density, arrangement)	8 layouts (see Layouts below)
Palette (optional)	Color override, replaces the style's default colors	macaron / warm / neon (see Palettes below)

Example: --style notion --layout dense makes an intellectual knowledge card; add --palette macaron to soften the colors without changing notion's rendering rules. A --preset is a shorthand for style + layout (+ optional palette).

Palette behavior: no --palette → style's built-in colors; --palette <name> → overrides colors only, rendering rules unchanged. Some styles declare a default_palette (e.g., sketch-notes defaults to macaron).

Outline Strategies

Three differentiated approaches — each produces a structurally different outline. The workflow recommends one; Path C generates all three and lets the user choose.

Strategy	Concept	Best for	Structure
A — Story-Driven	Personal experience as the thread, emotional resonance first	Reviews, personal shares, transformation	Hook → Problem → Discovery → Experience → Conclusion
B — Information-Dense	Value-first, efficient information delivery	Tutorials, comparisons, checklists	Core conclusion → Info card → Pros/Cons → Recommendation
C — Visual-First	Visual impact as core, minimal text	High-aesthetic products, lifestyle, mood content	Hero image → Detail shots → Lifestyle scene → CTA

Reference Images

User-supplied refs are separate from the internal "image-1 as anchor" chain (Step 3) — they layer on top of it.

Intake: via --ref <files...> or paths pasted in conversation.

• File path → copy to refs/NN-ref-{slug}.{ext}
• Pasted with no path → ask for the path, or extract style traits as a text fallback

Usage modes (per reference):

Usage	Effect
direct	Pass the file to the backend (typically on image 1 only, so the anchor propagates through the chain)
style	Extract style traits and append to every card's prompt body
palette	Extract hex colors and append to every card's prompt body

Record refs in each affected card's prompt frontmatter:

references:
  - ref_id: 01
    filename: 01-ref-brand.png
    usage: direct

At generation time: verify files exist. Image 1 with usage: direct + backend that accepts refs → pass via the backend's ref parameter (becomes the chain anchor). Images 2+ keep using image-1 as --ref per Step 3 — do NOT re-stack user refs on top (avoids conflicting signals). For style/palette, embed extracted traits in every prompt.

File Layout

image-cards/{topic-slug}/
├── source-{slug}.{ext}
├── analysis.md
├── outline-strategy-{a,b,c}.md    # Path C only
├── outline.md
├── prompts/NN-{type}-{slug}.md
├── NN-{type}-{slug}.png
└── refs/                          # only if --ref used

Slug: 2-4 words, kebab-case. "AI 工具推荐" → ai-tools-recommend. On collision, append -YYYYMMDD-HHMMSS.

Backup rule (applies throughout): before overwriting any file — source, outline, prompt, image — rename the existing one to <name>-backup-YYYYMMDD-HHMMSS.<ext>. This protects user edits.

Workflow

- [ ] Step 0: Load EXTEND.md ⛔ BLOCKING (interactive only)
- [ ] Step 1: Analyze content → analysis.md
- [ ] Step 2: Smart Confirm ⚠️ REQUIRED (Path A / B / C)
- [ ] Step 3: Generate images
- [ ] Step 4: Completion report

Step 0: Load EXTEND.md ⛔ BLOCKING

Check these paths in order; first hit wins:

Path	Scope
.baoyu-skills/baoyu-image-cards/EXTEND.md	Project
${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-image-cards/EXTEND.md	XDG
$HOME/.baoyu-skills/baoyu-image-cards/EXTEND.md	User home

• Found → read, parse, print a summary (style / layout / watermark / language), continue.
• Not found + interactive → run first-time setup (see references/config/first-time-setup.md) and save before anything else. Do NOT analyze content or ask style questions until preferences exist — this keeps first-run behavior predictable.
• Not found + --yes → skip setup, use built-in defaults (no watermark, style/layout auto-selected, language from content). Do not prompt, do not create EXTEND.md.

EXTEND.md keys: watermark, preferred style/layout, custom style definitions, language preference. Schema: references/config/preferences-schema.md.

Step 1: Analyze Content → analysis.md

1. Save the source (backup rule applies if source.md exists).
2. Run the deep analysis in references/workflows/analysis-framework.md: content type, hook potential, audience, engagement signals, visual opportunity map, swipe flow.
3. Detect source language, pick recommended image count (2-10).
4. Auto-recommend strategy + style + layout + palette using the Auto-Selection table above.
5. Write everything to analysis.md.

Step 2: Smart Confirm ⚠️ REQUIRED

Hard gate: this step is mandatory per the Confirmation Policy — Step 3 cannot start until the user confirms here (or explicitly opts out with --yes / equivalent wording in the current request).

Goal: present the auto-recommended plan and let the user confirm or adjust. Skip this step entirely under --yes — proceed with Path A using the analysis and any CLI overrides.

Display summary before asking:

  风格：[style] · 布局：[layout] · 配色：[palette or 默认] · 预设：[preset]
  图片：[N]张（封面+[N-2]内容+结尾）
  元素：[background] / [decorations] / [emphasis]

Then ask one question — three paths. Verbatim option copy: references/confirmation.md.

Path A — Quick confirm (trust auto-recommendation): generate a single outline using the recommended strategy + style → save to outline.md → Step 3.

Path B — Customize: ask five questions (strategy/style, layout, palette, count, optional notes) with the recommendation pre-filled — blanks keep the recommendation. Generate one outline with the user's choices → outline.md → Step 3. See references/confirmation.md.

Path C — Detailed mode: two sub-confirmations.

• Step 2a — Content understanding: ask selling points (multi-select), audience, style preference (authentic / professional / aesthetic / auto), optional context. Update analysis.md.
• Step 2b — Three outline variants: generate outline-strategy-a.md, outline-strategy-b.md, outline-strategy-c.md. Each MUST have a different structure AND a different recommended style — include style_reason in the frontmatter. Page-count heuristic: A ~4-6, B ~3-5, C ~3-4. Template: references/workflows/outline-template.md; frontmatter example in references/confirmation.md.
• Step 2c — Selection: ask three questions (outline A/B/C/Combined, style, visual elements). Save selected/merged outline to outline.md → Step 3.

Step 3: Generate Images

With confirmed outline + style + layout + palette:

Visual consistency — image-1 anchor chain: character / mascot / color rendering drifts between calls unless you anchor them. Generate image 1 (cover) first WITHOUT --ref, then pass image 1 as --ref to every subsequent image. This is the single most important consistency trick for this skill — don't skip it even if the backend also supports a session ID.

For each image (cover, content, ending):

1. Write the full prompt to prompts/NN-{type}-{slug}.md in the user's preferred language (backup rule applies).
2. Generate:
   • Image 1: no --ref (establishes the anchor).
   • Images 2+: add --ref <path-to-image-01.png>.
   • Backup rule applies to the PNG files.
3. Report progress after each image.

Watermark (if enabled in EXTEND.md): append to the generation prompt:

Include a subtle watermark "[content]" positioned at [position].
The watermark should be legible but not distracting.

See references/config/watermark-guide.md.

Backend selection: per the Image Generation Tools rule at the top — use whatever is available, ask once if multiple, before any generation. Under --yes, use the EXTEND.md preference and fall back to the first available backend. Prompt files MUST exist before invoking any backend.

Session ID (if the backend supports --sessionId): use cards-{topic-slug}-{timestamp} for every image; combined with the ref chain this gives maximum consistency.

Edit	Update prompts/NN-{type}-{slug}.md first, then regenerate with the same session ID
Add	Specify position, create prompt, generate, renumber subsequent files NN+1, update outline
Delete	Remove files, renumber subsequent NN-1, update outline

Always update the prompt file before regenerating — it's the source of truth and makes changes reproducible.

Notes

• Auto-retry once on generation failure before reporting an error.
• For sensitive public figures, use stylized cartoon alternatives.
• Smart Confirm (Step 2) is required; Detailed mode adds a second confirmation (2a + 2c).

Changing Preferences

EXTEND.md lives at the first matching path listed in Step 0. 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-image-cards 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-imagine — pin to the baoyu-imagine skill.
  • preferred_image_backend: ask — confirm backend every run.
  • preferred_style: notion, preferred_layout: dense, preferred_palette: macaron, language: zh.
  • watermark.enabled: true + watermark.content: "@handle" — add a watermark.
