cover

cover is a command for coding agents from geo-mena/distill. It costs 21 tokens per session (1,384 once invoked), scanned A, original, MIT.

A command that creates a 1600×500 SVG banner for a project's README, with a title, subtitle, and three pieces of project information.

In plain words
What is it for?
Use it to make a project introduction banner containing the project name, a short description, and details such as its scope, runtime, or output.
Why use it?
It removes the work of measuring and styling a README cover to match the specified article-like design.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

cover 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Load the distill-design skill, then produce a 1600×500 SVG cover banner for the project named in $@.

Workflow:

  1. Read plugins/distill-design/SKILL.md decision tree row "Cover banner for a project README" — it lists every measurement. Then read the canonical reference at plugins/distill-design/resources/covers/distill-design-system.svg and the article-hero source at plugins/distill-design/ui_kits/article/Chrome.tsx (ArticleHeader component).
  2. From $@, extract: project name (h1), one-sentence subtitle, and three byline cells (default labels: SCOPE, VALIDATED, OUTPUT — but adapt to the project; e.g. for a library it might be SURFACE, RUNTIME, SHIPS WITH). If the user only gave a name, ask one clarifying question for the subtitle and 3-cell content.
  3. Write a single self-contained SVG with viewBox="0 0 1600 500", paper background #fdfdfd, and an embedded <style> block mirroring distill-design-system.svg exactly — same class names, same sizes.

Layout (from the canonical reference; do not deviate):

  • Background: <rect width="1600" height="500" fill="#fdfdfd"/>.
  • Left column (eyebrow + h1 + subtitle + hairline + 3-col byline grid):
    • Eyebrow: x=96 y=140, class eyebrowfont-size: 12px; font-weight: 500; letter-spacing: 1.44px; fill: #6a6a6a;. Content: uppercase 2-token tagline ending in the project name's domain.
    • h1: x=96 y=200, class h1font-size: 56px; font-weight: 700; letter-spacing: -0.84px; fill: #000;. (Pure #000 is allowed here — h1 is the only place.)
    • Subtitle: x=96 y=255, class subfont-size: 22px; font-style: italic; fill: #4a4a4a;.
    • Hairline rule: <line x1="96" y1="296" x2="960" y2="296" stroke="#e8e8e4" stroke-width="1"/>.
    • 3-col byline grid: cells at x=96 / x=384 / x=672, label at y=320 (class meta-label, 10px uppercase 0.1em fill #6a6a6a), value at y=346 (class meta-value, 14px fill #2a2a2a), italic affiliation at y=367 (class meta-aff, 13px italic fill #6a6a6a).
  • Right column (FiLM-style fan-out diagram):
    • Caption "prompt" (or context-appropriate noun) at x=1070 y=160, class stack-label, text-anchor middle.
    • Input TensorVector: 4 stacked salmon cells, x=1056, widths 28, alternating shades from the Primitives.tsx salmon palette (#fdecea, #f8c2bb, #f5a39b, #fbd9d4), stroke #c44a3f.
    • Arrow input → block: solid #666 1.5px from (1098,240) to (1158,240), with a triangular #666 arrowhead.
    • "Design system"-style block: 70×160 rounded rect at (1170,170), fill #fbd9d4, stroke #c44a3f, with a vertical-rl label rotated -90° centered in the block (class vlabel, 13px medium fill #2a2a2a).
    • Fork stem: solid line (1240,240) → (1280,240).
    • 3 orthogonal branches (90° bends, never diagonal): stem at x=1280 forks to top (y=175), mid (y=240), bottom (y=305), each ending at x=1322 with a triangular arrowhead.
    • 3 output blocks at x=1334, width=120, height=40, rx=4, fill #fdecea, stroke #c44a3f. Labels via class out-label (14px medium #2a2a2a), text-anchor middle, centered in each block. Use 3 nouns describing the project's output surface.
    • "n artifacts"-style mini-label below the bottom block, class stack-label.
    • PointerGlyph end-stop: orange-yellow circle #f5b942 with white pointing-hand path (copy from distill-design-system.svg), translated to anchor the right edge near the mid output.

Hard constraints (non-negotiable):

  • English only.
  • No emoji.
  • No year literals anywhere in the cover (2017–2021 is in the canonical reference because the canonical IS the system itself; for any other project, omit dates entirely or use timeless qualifiers).
  • No marketing superlatives in the subtitle. State what the project does in plain terms.
  • Pure #000 is allowed on h1 only. Body labels stay #2a2a2a / #4a4a4a / #6a6a6a.
  • Strokes #666 1.5px rounded caps. No gradients, no shadows.
  • Output is a single self-contained SVG — embedded <style>, no external font, no external <use href>.

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.

cover is a command published in the GitHub repository geo-mena/distill (2 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 1,384 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
