bid-reader（投标阅读器）

bid-reader Skill

Overview

A lightweight skill to extract readable text from bid and tender documents in PDF, Word (.docx), and Excel (.xlsx/.xls) formats. It can be invoked from the OpenClaw UI or other agents to quickly pull the full textual content of a file for analysis, search, or summarisation.

Usage

bid-read <file-path>

• <file-path> should be an absolute or workspace‑relative path to a document.
• The skill prints the extracted plain‑text to stdout, which OpenClaw captures and returns to the caller.

Example

bid-read /home/zhenxing/投标文件/招投标项目1/13.上海联通/投标文件.pdf

The command returns the full text of the PDF, ready for further processing (e.g., keyword search, summarisation).

Installation

Copy the skill folder into your workspace under skills/bid-reader. Install required Python packages:

pip install -r $(pwd)/skills/bid-reader/requirements.txt

The skill is then available as an agent command.

Implementation Details

• PDF: Uses pdfplumber to extract text page‑by‑page.
• Word: Uses python-docx to read paragraphs.
• Excel: Uses pandas (with openpyxl/xlrd) to read all sheets and concatenate cell values.

Limitations

• Only .pdf, .docx, .xlsx, and .xls are supported. Other formats will be ignored.
• Large files may take a few seconds to process.
• Tables are flattened into whitespace‑separated rows; complex formatting is not preserved.

Future Enhancements

• Add OCR fallback for scanned PDFs (e.g., via pytesseract).
• Support selective page or sheet extraction.
• Provide a JSON output mode with structural metadata.
