fal-workflow-json

fal-workflow-json is a skill for Claude Code from mertagralii/fal.ai-butler. It costs 78 tokens per session (571 once invoked), scanned A, original, MIT.

A guide to describing fal.ai workflows as JSON, a text format commonly used to represent structured data. It covers workflow nodes, model selection, references between nodes, and validation.

In plain words
What is it for?
Use it to search for suitable models, inspect their input schemas, build workflow nodes, reference earlier outputs, check documentation, and validate workflow files without running models.
Why use it?
It helps prevent workflows from using the wrong model inputs, invalid references, or unsupported structure before they are shown to a user.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: $skill-name invocation.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

fal-workflow-json 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 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.

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.

What it actually says

fal workflow JSON

fal'ın workflow tanım biçimi ve model seçimi. contents.nodes altındaki düğümler, run/display tipleri, app alanı ve $düğüm-id.alan referans sözdizimi.

Referanslar

  • references/schema.md — şemanın tam tanımı, kampanya girdileri, doğrulanan kural listesi, bilinen import belirsizliği
  • references/model-selection.md — modaliteye göre model arama, şemadan eleme, tutarlılık kuralı

Kullanılan fal MCP araçları

Araç Ne için
search_models Modaliteye göre aday model bulmak
get_model_schema Adayın girdi alanlarını ve kısıtlarını okumak
get_pricing Fiyat — katalogda yok, ayrı araçla alınır
recommend_model Belirsizlikte aday daraltmak
search_docs Şema belirsizse fal dokümanına bakmak

run_model, submit_job ve upload_file kullanılmaz — plugin hiç para harcamaz. Bu agent'ların araç listesinde zaten yoklar.

Değişmez kural

Üretilen her workflow.json, kullanıcıya verilmeden önce doğrulayıcıdan geçer:

node "${CLAUDE_PLUGIN_ROOT}/scripts/validate-workflow.mjs" ".fal-butler/campaigns/<slug>/workflow.json" --catalog ".fal-butler/cache/models.json"

Katalog dosyası lib/cache.mjs tarafından models anahtarıyla yazılır ve { fetchedAt, data } zarfı taşır; doğrulayıcı zarfı kendisi açar. Katalog henüz yoksa --catalog bayrağını at — endpoint kontrolü atlanır, yapı ve referans kontrolü yine çalışır.

Çıkış kodu 0 değilse dosya kullanıcıya verilmez — hatalar düzeltilip tekrar doğrulanır. Hatalı JSON'u teslim etmek, hatayı fal'ın import ekranında öğrenmek demektir.

Files

What ships with it

2 files 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.

Changes

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.
