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.

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 | $0.01198 | $0.01198 |
| Opus 5 | $0.00599 | $0.00599 |
| Sonnet 5 | $0.00240 | $0.00240 |
| Haiku 4.5 | $0.00120 | $0.00120 |
Grade A, and why
poster-maker CLAUDE.md 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 4d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Poster Maker
Project Purpose
A marketing poster generator powered by Claude Code. Creates visually striking posters as single HTML/CSS files, exportable to PNG/PDF. Works for any type of poster — event flyers, product launches, conference talks, DJ gigs, meetups, sale announcements, or anything else.
Project Structure
posters/ HTML poster files (the output)
exports/ Exported PNG/PDF files (gitignored)
assets/ Images, logos, photos for use in posters
scripts/
export.js Playwright PNG/PDF export (auto-detects dimensions)
screenshot.js Playwright preview screenshots (auto-detects dimensions)
dimensions.js Shared body-CSS dimension parsing (px, mm, in)
screenshot-url.js Capture a LIVE URL at device viewports into assets/<slug>/ (GPU forced on for WebGL sites)
frame-screenshot.js Frame a screenshot on a social-ready canvas (screenshot-frame.html is its template)
remove-bg.py Background removal (requires rembg)
.claude/commands/
setup.md /setup — install dependencies and verify setup
new-poster.md /new-poster — generate a poster
export-poster.md /export-poster — export to PNG/PDF
remove-bg.md /remove-bg — remove image background
Commands
/new-poster— main command. Generates a poster from a description. See the command file for full design principles, font pairings, and image handling./export-poster— export a poster to PNG or PDF using Playwright./remove-bg— remove background from an image using rembg (Python). Installs on first use.
Key Rules
- Posters are single HTML files with all CSS inline — the only external references are Google Fonts and images from
assets/. - Body dimensions are the poster size (default 1080x1920) with no scroll/margin.
- Images go in
assets/, organized in subfolders per project (e.g.,assets/deep-frequencies/,assets/nexus-launch/). Referenced via relative paths from poster files (../assets/project-name/photo.jpg). - Always include
@media printwith-webkit-print-color-adjust: exact. - After creating/editing a poster, open it with
open posters/<filename>.html. - Always take a Playwright screenshot after creating/editing a poster:
node scripts/screenshot.js posters/<filename>.html— then read the PNG to visually verify the result before presenting to user. - Iterate with the user until they're happy, then offer export.
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.
