At a glance
Extracts text from images and PDFs, including invoices, receipts, ID cards and tables, with plain text, JSON or Markdown output and a choice of OCR providers.
- Pulling structured fields out of an invoice or receipt PDF
- SKILL.md covers ocr_recognize, ocr_providers, PDF support and Multi-page PDF response, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Converting a photographed table into Markdown
What it does
The skill wraps the ocr_recognize tool, called through the tai command line. It takes a file path or URL for an image or PDF and can use either a vision-language model or a traditional OCR service such as Baidu, Google, Azure or PaddleOCR, choosing one automatically when you do not name a provider.
Options control the recognition type (general by default, with presets such as table and invoice), the output format (text, JSON with coordinates and fields, or Markdown), accurate or standard mode, a language hint and a PDF page range. A custom prompt can steer vision-language recognition only; traditional OCR ignores it.
When your agent uses it
- Pulling structured fields out of an invoice or receipt PDF
- Converting a photographed table into Markdown
- Reading text from ID cards, bank cards or business licenses
- Recognizing handwritten documents or a page range of a scanned PDF
Example prompts
- “Run OCR on ./scans/invoice.pdf and return the fields as JSON.”
- “Extract the table in table.png as Markdown.”
- “Read pages 1-5 of report.pdf and give me the text in Markdown.”
- “Use the Baidu provider to recognize the Chinese text in doc.png.”
Requirements
- The tai command line tool
- An OCR provider or LLM connector set up for it
What it can do on your machine
Read from SKILL.md and the folder at commit 0b6ee5f. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Yao OCR Tools loads about 1.6k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 508 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 508 words (~1,635 tokens).
“Two tools for optical character recognition, supporting both VLM-OCR (vision language models) and traditional OCR APIs (Baidu, Google, Azure, PaddleOCR).”
