Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.01628 |
| Opus 5 | $0.00034 | $0.00814 |
| Sonnet 5 | $0.00013 | $0.00326 |
| Haiku 4.5 | $0.00007 | $0.00163 |
Grade A, and why
compose-preview-design-board scanned grade A with 1 finding 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Compose Preview — Design Board
Assemble the PNGs produced by compose-preview into a single, self-contained
HTML design board — categories, groups, captions, and layout — so a set of
renders travels as one coherent brief instead of loose screenshots. The board
is built for import into Claude Design (and similar design tools).
This skill assumes the compose-preview skill is installed — it owns the
renderer, CLI, and Gradle plugin that produce the PNGs this skill arranges.
Check first with compose-preview --version; if it's missing, ask the user to
run the bootstrap installer (which covers the compose-preview skills):
curl -fsSL https://raw.githubusercontent.com/yschimke/skills/main/scripts/install.sh \
| bash
Source
This skill is maintained at
github.com/yschimke/skills under
skills/compose-preview-design-board/. To check for updates, compare the
installed copy against main (e.g. git ls-remote https://github.com/yschimke/skills HEAD). The renderer and CLI that produce
the input PNGs ship from
github.com/yschimke/compose-ai-tools.
When to use this skill
- You have a set of rendered
@PreviewPNGs and want to hand them to a designer or to Claude Design as a structured brief — grouped by feature/screen, with captions and intent notes — not a flat folder of images. - You want one portable artifact (a single HTML file, images inlined) that can be opened in a browser, served from a branch / GitHub Pages, or dropped into a design tool.
For rendering the previews, see the compose-preview skill. For reviewing a UI PR by diffing base vs head renders, see compose-preview-review. This skill is the export/presentation step that sits on top of those.
Workflow
-
Render previews. Use the compose-preview CLI to produce PNGs and the manifest of what was rendered:
compose-preview show --module <m> --json > /tmp/<m>-show.json
What ships with it
1 file 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.
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.
