screen-builder

screen-builder is an agent for Claude Code from atezer/FMCP. It costs 91 tokens per session (1,076 once invoked), scanned A, original, MIT.

An agent for creating Figma screens from written ideas, uploaded images, Figma examples, or a request for suggestions. Figma is a tool for designing user interfaces.

In plain words
What is it for?
Use it to design screens in Figma, create alternatives, or draw inspiration from an uploaded image, a website image, or an existing Figma design.
Why use it?
It gives design requests a defined path even when the input is incomplete or starts from a visual reference. The main coordination and review logic is handled by a separate screen-design workflow.

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

screen-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 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.

Screen Builder — Claude Code Thin Delegator

Bu agent sadece Claude Code'a özgü bir wrapper'dır. Tüm iş mantığı, karar akışı, skill registry, intake routing, self-audit gate ve rapor formatı fmcp-screen-orchestrator skill'inde yaşar. Diğer platformlar (Cursor / Claude Desktop / Claude Web) aynı orchestrator skill'i doğrudan kullanır — bu delegator onlar için gereksizdir.

Görev

Adım 0 — Orchestrator Skill'i Yükle

Read("skills/fmcp-screen-orchestrator/SKILL.md")

Essentials bölümü common case için yeterlidir. Advanced bölümüne sadece şu koşullarda in:

  • Intake modu karmaşık (nested benchmark, hybrid image + metin)
    1. self-audit denemesi başarısız
  • Skill evolution ihtiyacı doğdu
  • Non-obvious error (plugin bağlantı kaybı, timeout döngüsü)

Adım 1 — Kullanıcı Talebini Intake Mode'a Eşle

Orchestrator Essentials'ındaki "Karar Akışı" bölümüne bak. Talebi şu modlardan birine ata:

  • text_only — net metin açıklaması
  • figma_benchmark — Figma URL pattern (figma.com/file/...?node-id=)
  • image_uploaded — kullanıcı sohbete görsel eklemiş
  • image_url — HTTP URL ama Figma değil (dribbble/behance/vs)
  • no_idea — kullanıcı "bilmiyorum/bir şey öner/fikrim yok" diyor

Belirsizse önce Read("skills/fmcp-intent-router/SKILL.md") ile netleştir.

Adım 2 — Orchestrator Karar Akışını Uygula

Orchestrator'ın "Karar Akışı" tablosunu takip et. Sub-skill'leri yalnızca karar anında Read et (lazy loading):

  • Intake image/benchmark modunda mı? → Read("skills/inspiration-intake/SKILL.md")
  • figma_execute çağıracak mısın? → Read("skills/figma-canvas-ops/SKILL.md") pre-flight
  • Ana üretim? → Read("skills/generate-figma-screen/SKILL.md")

Sezgisel "belki lazım olur" Read yasak. Gereksiz sub-skill yüklemesi sub-agent context'ini şişirir.

Adım 3 — Self-Audit Gate (Zorunlu)

Teslim öncesi:

figma_validate_screen(nodeId=<wrapper_id>, minScore=80)

minScore=80 her çağrıda explicit. Başarısız → hedefli düzelt → yeniden validate. 3 deneme fail → Advanced bölümünün Error Recovery Matrix'ine in.

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.

It adds 91 tokens to every session and 1,076 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings.

Forger juror seat for a muriel jury. Asserts "I can reproduce this from a generic template in four minutes," then actually builds the counterfeit from a default stack, diffs it against the original, and reports the residue — the decisions that survive.

muriel-pedant

The Pedant jury seat. Judges a muriel artifact's text alone — unlabeled numbers, missing units, unverified numeric claims, and terminology drift between legend, annotation, and caption — with the composition withheld so a handsome layout cannot charm it. Applies the numeric-claim probe list from muriel-critique.md…

The Squinter jury seat. Blurs a muriel artifact with muriel.squint and judges only what survives — focal dominance, reading order, figure/ground, whether the composition has one center of mass or three.

The Stranger jury seat. Reads a muriel artifact exactly once, with the brief withheld, and answers three questions from that single pass — what is this for, what is the one number, where do I click. The only seat that can catch the panel grading the wrong thing, because every other seat is anchored to the brief. Fails…
