AC pdf-to-text
Extract plain text from PDF documents using the MinerU API. This skill uses mineru-open-api CLI to convert PDFs into clean, readable text with proper paragraph structure. Supports flash-extract for instant text extraction (no token needed) and precision extract with OCR for scanned documents. Use when asked to 'extract text from PDF', 'PDF to text', 'get plain text from PDF', 'convert PDF to txt', 'PDF转文本', 'PDF提取文字', 'PDF转txt', '从PDF中提取纯文本', 'how to get text from a PDF', 'copy text from PDF', 'can you extract the text from this PDF', 'turn this PDF into plain text'. Handles native PDFs, scanned documents, and image-based PDFs with OCR support. Ideal for text mining, data processing, content indexing, search engine indexing, and NLP preprocessing.
As a process C 53/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

- 0Failures and branches. Linear process with no failure handling

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
