doc-reader skillA
doc-reader is agent-read markdown (skill) from hkuds/vibe-trading: Read any common document/data file — PDF, Word (.docx), Excel (.xlsx/.xls), PowerPoint (.pptx), images (OCR), CSV/TSV, plain text, JSON/YAML/TOML, HTML/XML, and most source-code files. Use the `read_document` tool..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.
What the file says
# Universal Document Reader ## Purpose Return extracted text from any supported file in a single unified JSON envelope. The tool dispatches by file extension — you always call the same tool regardless of format. ### Supported formats | Category | Extensions | Notes | |---|---|---| | PDF | `.pdf` | Text pages extracted in ms; scanned/image pages fall back to OCR | | Word | `.docx` | Paragraphs + table cells | | Excel | `.xlsx`, `.xls` | All sheets, first 100 rows per sheet as preview | | PowerPoint | `.pptx` | Slide text content | | Images | `.png/.jpg/.jpeg/.gif/.bmp/.webp/.tiff` | OCR only | | CSV / TSV | `.csv`, `.tsv` | Raw text with encoding fallback | | Plain text | `.txt/.md/.log/.rst` | Encoding fallback | | Config | `.json/.yaml/.yml/.toml/.ini/.cfg/.env` | Raw text | | Markup | `.html/.htm/.xml` | Raw text (no HTML stripping) | | Source code | `.py/.js/.ts/.tsx/.go/.rs/.java/.cpp/.c/.sql/.sh/...` | Raw text | | Unknown extension | anything else | Best-effort read as UTF-8/GBK text | **Blocked** (rejected at `/upload`): executables (`.exe/.dll/.so/...`) and archives (`.zip/.tar/...`). Ask the user to unpack archives locally first. ## Usage …
Read the whole file at its exact version.
How to install
mdr add hkuds/vibe-trading/doc-reader@git:20260715.a45b024mdr add hkuds/vibe-trading/doc-reader@sha256:01fd83063ac5aefcPin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
