What it does

Scanlume OCR API is an agent skill from aiskillstore/marketplace. Use when calling the Scanlume OCR API for screenshots, JPG, PNG, or image-based tables, especially when a task needs base64 data URLs, mode selection between simple and formatted OCR, or table-aware structured output. Tambem use quando for necessario chamar a API OCR do https://www.scanlume.com/ para screenshots, JPG, PNG ou tabelas em imagem.

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/api-contract.md` and `references/output-shapes.md`).

It sits in Documents & Office, covering Structured output and tool calling. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Calling the Scanlume OCR API for screenshots
  • Image-based tables
  • Especially when a task needs base64 data URLs
  • Mode selection between simple and formatted OCR

Example prompts

  • “/scanlume-ocr-api”

Requirements

  • Python 3
  • A credential in SCANLUME_API_KEY

Workflow steps

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

  1. Confirm the input is an image, not a PDF.
  2. Read references/api-contract.md before building the request.
  3. Choose simple only for raw text speed and lower cost.
  4. Choose formatted for headings, multi-block layouts, Markdown, HTML, and tables.
  5. If the user gives a local file path, prefer scripts/scanlume_ocr.py to build the data URL and call the API.
  6. Read references/output-shapes.md before consuming formatted responses, especially table blocks.
  7. State clearly when a request is blocked by public API limits, such as PDF OCR beta access.

What it can do on your machine

Read from SKILL.md and the folder at commit 755bc35. 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:

    • python

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

  • Network

    Links to these hosts (documentation or services it may open):

    • scanlume.com

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

  • Credentials

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

    • SCANLUME_API_KEY

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

Context cost

Scanlume OCR API loads about 1.2k tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 91 tokens; SKILL.md has 631 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
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
~3k

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 passed

The automated check found no risky patterns in SKILL.md.

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 631 words (~1,244 tokens).

“Use this skill when the task is specifically about calling the public OCR API behind https://www.scanlume.com/, not when the user only wants the website UI.”
