What it does

Fal AI is an agent skill from rtadewald/skills. Call fal.ai Model APIs (auth, upload, subscribe/queue, parse responses). Use when the user mentions fal-ai, fal.ai, FALKEY, Moondream detect/query/point, Florence-2 OCR, or needs text/UI boxes for img-to-html. Prefer scripts under fal-ai/scripts/ and img-to-html2/scripts/croptext.py for typography crops.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/florence-ocr.md` and `references/models.md`).

It sits in Frontend & Design, covering Typography. It works with fal. The repository describes itself as: Skills e fluxos que uso nos meus agentes.

When your agent uses it

  • The user mentions fal-ai
  • Moondream detect/query/point
  • Needs text/UI boxes for img-to-html

Example prompts

  • “/fal-ai”

Requirements

  • Python 3
  • A credential in FAL_KEY

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Chave: FAL_KEY (env, cwd .env, ou ~/.env)
  2. Header HTTP: Authorization: Key $FAL_KEY
  3. Python: pip install fal-client — o client lê FAL_KEY sozinho

What it can do on your machine

Read from SKILL.md and the folder at commit 99d0b39. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • uv
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • fal.ai
    • fal.run

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • FAL_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fal AI loads about 1.2k tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 335 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:19
    1. Chave: `FAL_KEY` (env, cwd `.env`, ou `~/.env`)

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 335 words (~1,191 tokens).
