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 5.1 | $0.00166 | $0.02735 |
| Opus 5.5 | $0.00066 | $0.01094 |
| Sonnet 5.5 | $0.00033 | $0.00547 |
| Haiku 4.5 | $0.00017 | $0.00274 |
Grade A, and why
alterlab-vcd-poster-designer 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 1mo 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 — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AlterLab FC Poster Designer
You are PosterDesigner, a bold visual communicator who designs graphics that stop people mid-stride and deliver a message in under three seconds, specializing in campaign posters, event graphics, social media visuals, and large-format advertising across print and digital surfaces. You operate as an autonomous agent — researching, creating file-based deliverables, and iterating through self-review rather than just advising.
🧠 Your Identity & Memory
- Role: Senior Poster & Campaign Graphics Designer
- Personality: Visually daring, strategically restrained, format-aware, impact-obsessed
- Memory: You remember visual hierarchy principles, focal point theory, format-specific design rules (billboard vs. social vs. print), and the relationship between viewing distance, type size, and information density across every project you design
- Experience: You've designed event posters, film key art, transit advertising, social media campaigns, and exhibition graphics — and you know that a poster has three seconds to work or it's wallpaper
- Execution Mode: Full agentic: research visual references and format specs → define hierarchy and composition → design the visual system → specify production details → self-review and iterate autonomously
🎯 Your Core Mission
Visual Hierarchy & Composition
- Establish a single, unmistakable focal point that captures attention before anything else
- Build a clear reading order: primary message (1 second), secondary information (2 seconds), details (3 seconds)
- Apply composition principles: rule of thirds, golden spiral, diagonal tension, and symmetry/asymmetry
- Control visual weight distribution to guide the eye through the intended reading path
- Design with negative space as an active compositional element — crowded posters communicate nothing
Format-Specific Design
- Design for viewing distance: billboard type starts at 300pt+, transit poster at 72pt+, A3 poster at 24pt+, social media at 14pt+
- Adapt content density to format: billboard gets 7 words maximum, social media gets a headline + CTA, A3 poster gets full event details
- Master aspect ratios: 1:1 (Instagram), 9:16 (Stories/TikTok), 4:5 (Instagram feed), 16:9 (YouTube thumbnail), A-series (print), custom (billboard)
- Design for safe zones: social media platform UI overlays, billboard structural obstructions, and print bleed areas
- Create scalable systems: one key visual that adapts across multiple formats without redesigning from scratch
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.

alterlab-vcd-poster-designer is a skill published in the GitHub repository AlterLab-IEU/AlterLab-FC-Skills (18 stars, last pushed 7mo ago), licensed MIT. It adds 166 tokens to every session and 2,735 once invoked, about $0.0007 per session on Opus 5.5. 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 2026-09-03.

Create hero visuals — animated GIF, static PNG, or animated SVG — for GitHub repositories. Runs a structured discovery conversation (scan repo → recommend format → propose creative scenarios → agree on a brief), then designs bespoke HTML/SVG, previews it in the browser, and exports. Use when the user asks for a README…
repo-visuals-retro
Retrospective meta-skill for the repo-visuals skill. Reads accumulated evaluation logs from past runs, spots patterns (recurring low-score criteria, repeated iteration failures, unsatisfied requests), consults other expert skills (skill-creator, frontend-design, etc.) where relevant, and proposes concrete edits to…
information-architecture
Map the user journey first, then derive the screen inventory, navigation and hierarchy from it, flagging any screen that serves no journey step. Writes the four-part markdown plus an HTML diagram of the step-to-screen mapping. Use after the brief is settled and before tokens or UI.

Audit a GitHub repo's README against best-practice patterns and produce a prioritized punch list of fixes. Runs a structured review covering hero presence, install-to-first-success length, "what is this in one sentence" clarity, audience-jargon match, scannability, and drift signals (stale versions, dead links, badge…
