What is lieflat-xhs-longform?

A collection of templates and instructions for making readable 3:5 vertical Xiaohongshu (小红书) article images. Xiaohongshu is a Chinese social platform built around visual posts.

It is for creating Chinese-language article cards, product reviews, AI notes, brand essays, and other long-form social images from HTML templates.

It provides a defined structure for turning written material into a continuous reading card instead of an unreadable slide or title cover.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00067	$0.00774
Opus 5	$0.00034	$0.00387
Sonnet 5	$0.00013	$0.00155
Haiku 4.5	$0.00007	$0.00077

Security

Grade A, and why

lieflat-xhs-longform 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.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/audit-assets.mjs, scripts/audit-languages.mjs, scripts/capture-screenshots.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Lieflat XHS Longform

What This Skill Does

Create one vertical Xiaohongshu longform article card. The output is a readable 3:5 image, not a slide deck and not a cover.

Before choosing a style, read:

assets/catalog.json
references/style-understanding.md

Use assets/templates/<template-id>/zh.html as a starter. Copy it into the user's workspace before editing.

Core Rules

Output should read as a continuous article card: title, short subtitle if needed, section heading, body, and compact footer.
Do not make it look like a PPT slide or a cover card.
Default to Chinese visible copy unless the user explicitly requests another language.
Treat xhs-story-field as a low-frequency style. Do not choose it by default for ordinary AI notes, product reviews, technical explainers, listicles, or general article cards. Use it only when the user explicitly asks for Story Field / 故事集, or when the source genuinely needs an archival, cinematic, project-field-report narrative with story-led paragraphs.
Do not mechanically preserve decorative blocks from the demo. Keep only the structures that help the article read better.
Preserve the chosen style's palette, type rhythm, ornaments, and atmosphere.
Do not invent claims, numbers, product facts, or quotes.
Do not mix template systems. If switching from one longform style to another, start again from the new style's starter HTML instead of carrying over the previous template's DOM, class names, layout modules, CSS variables, or decorative blocks.

Canvas And Export

CSS canvas: 600px × 1000px, 3:5.
Default export: 1200px × 2000px PNG with deviceScaleFactor: 2.
Body text baseline: around 22-24px, line-height around 1.7-1.85.
Section headings: around 26-30px.
Inner padding: around 50px, adjusted to the chosen style.

After creating the HTML, run:

node scripts/capture-xhs-card.mjs --html <path-to-html> --out <path-to-card.png>

For a multi-image carousel:

node scripts/capture-xhs-carousel.mjs --html <path-to-html> --out-dir <folder>

What ships with it

23 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
