flier

flier is a skill for Claude Code from asgeirtj/system_prompts_leaks. It costs 7 tokens per session (525 once invoked), scanned A, original, CC0-1.0.

A guide for designing a print-ready flier as one fixed-size HTML page. The page is meant to print as a single full-bleed sheet, such as letter or A4.

In plain words
What is it for?
Use it to create one-page promotional or informational fliers with controlled print size, margins, layout, and clipping.
Why use it?
It prevents content from reflowing into extra pages or being placed outside the printable page area.

Getting it into your agent

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

flier 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.

What it actually says

Flier

Design a print-ready, single-page flier as one self-contained HTML file: exactly one fixed-size page.

Sheet setup:

  • START by calling copy_starter_component with kind: "doc_page.js", then build the flier as ONE explicitly paginated page: …. The component owns the page box, the desk background that disappears at print, the page break discipline, and all print geometry — do NOT write your own @page rule, body background, or hard-coded paper dimensions, and never add an omelette-owns-print meta. The print dialog must show exactly 1 page.
  • The flier prints as a FIXED full-bleed page box with overflow hidden — letter by default, the user's chosen paper (letter, A4, …) when they export — so content that misses the box is clipped, never reflowed. Design the flier to FILL the page box and fit letter and A4 alike without overlap.
  • The page is full-bleed: the flier owns its own inset — keep a visual margin of at least 4% of the page on every edge, and keep everything inside it.
  • Never viewport units (vh/vw) — they track the window, not the page.

A flier is read at a distance, in passing, in under three seconds:

  • One dominant element — usually a headline under ~6 words — sized so it reads across a room (think 8cqh+), everything else clearly subordinate.
  • The five Ws grouped tight and scannable: what, when, where, cost, and one way to act (QR-sized URL, phone number, or tear-off) — not scattered through prose.
  • Strong flat color blocks and vector shapes over photos and gradients; high contrast; body text in near-black on light stock.
  • Generous whitespace beats more words — cut copy until the hierarchy is unmissable.
  • Optional: a tear-off fringe along the bottom edge (a row of narrow cells with dashed left borders and rotated contact text) when the user wants phone-number slips.

Check the print preview: nothing clipped, nothing spilling to page two, colors that still work in grayscale.

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.
