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 | $0.00112 | $0.01848 |
| Opus 5 | $0.00056 | $0.00924 |
| Sonnet 5 | $0.00022 | $0.00370 |
| Haiku 4.5 | $0.00011 | $0.00185 |
Grade A, and why
figjam-diagram-builder 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 7d 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.

FigJam Diagram Builder (FMCP Safe Mode)
Overview
Bu skill, FMCP ile FigJam üzerinde programatik diyagram üretirken iki kritik problemi çözer:
- Tool result boyutunun büyüyerek oturumu kırması
- Çok adımlı üretimde context şişmesi ve kararsız yerleşim
Skill, her adıma kısa ve güvenli dönüş zorunluluğu getirir; node/connector pozisyonlarını saklamak yerine yeniden hesaplar.
Prerequisites
- F-MCP Bridge plugin açık ve bağlı olmalı
- Hedef FigJam dosyası Figma Desktop'ta açık olmalı
- Kullanıcıdan şema tipi alınmalı (swimlane, flowchart, karar ağacı vb.)
F-MCP skill koordinasyonu
- Süreç/diyagram odaklıdır; token veya kod üretim döngüsüyle zorunlu sıra yoktur. Ürün ekranı ve implementasyon için implement-design veya ai-handoff-export ayrı akıştır; tuval DS düzeltmesi için apply-figma-design-system / audit-figma-design-system.
Required Workflow
Step 1: Plugin Bağlantısını Doğrula
figma_get_status()
figma_list_connected_files()
pluginConnected=falseise kullanıcıdan plugin'i ilgili FigJam dosyasında yeniden çalıştırmasını iste.- Port uyuşmazlığında plugin portunu
bridgePortile eşleştir.
Step 2: Güvenli execute kuralları
figma_execute dönüşü her zaman kısa olmalı:
- Kısa durum string'i:
"OK: 12 node, 14 connector" - Kısa hata string'i:
"HATA: ..."(maksimum ~200 karakter) - Küçük JSON:
{"count": 12, "x": 3500, "y": 100}
Asla büyük node listesi, currentPage.children, büyük JSON veya pluginData dump döndürme.
Timeout: Varsayılan 5000ms. Çok node oluşturma işlemlerinde timeout parametresini artır (maks 30000ms). Bkz. "Common Issues" bölümü.
FigJam Font Kuralı
createShapeWithText() varsayılan fontu "Inter Medium"'dir. Shape text düzenlemeden ÖNCE:
await figma.loadFontAsync({ family: "Inter", style: "Medium" });
"Inter Regular" yüklemek YETMEZ — FigJam shape'leri "Medium" kullanır. Alternatif olarak mevcut fontu dinamik kontrol et:
await figma.loadFontAsync(shape.text.fontName);
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.

figjam-diagram-builder is a skill published in the GitHub repository atezer/FMCP (9 stars, last pushed 1mo ago), licensed MIT. It adds 112 tokens to every session and 1,848 once invoked, about $0.0006 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.
