word-read-write

name word-read-write description Create and read Microsoft Word (.docx) documents. Use this skill when you need to generate reports/letters/templates as .docx or extract readable text from existing .docx files. license MIT author AIPOCH Source : https://github.com/aipoch/medical-research-skills When to Use Generate Word reports (e.g., weekly status, audit summaries) from structured data in Node.js. Produce standardized memos/letters/templates with consistent page size, margins, headings, and tables. Export documents that must render reliably across Microsoft Word and Google Docs (tables, shading, widths). Insert images, headers/footers, page numbers, page breaks, and a table of contents programmatically. Extract text from existing .docx files for indexing, review, or conversion to Markdown. Key Features Create .docx documents using the docx (docx-js) library. Explicit page setup (US Letter vs A4), margins, and landscape handling. Style control (default font, overriding built-in Heading styles for TOC compatibility). Proper list generation (bullets/numbering via numbering config, not Unicode characters). Robust table rendering rules (DXA widths, column widths + cell widths, shading, borders, padding). Images with required metadata and transformations. Page breaks, headers/footers, and page numbering. Table of contents generation based on Word heading levels. Read/extract .docx content via Pandoc conversion.

Page sizing (DXA) : Word uses DXA units where 1440 DXA = 1 inch . docx-js defaults to A4 ; for US documents set US Letter explicitly: 12240 x 15840 . With 1" margins, content width is 12240 - 1440 - 1440 = 9360 DXA . Landscape orientation : docx-js swaps width/height internally for landscape. Provide portrait dimensions and set orientation: PageOrientation.LANDSCAPE . Headings and TOC : TOC generation requires paragraphs using HeadingLevel.* . To override built-in heading appearance, use exact style IDs: "Heading1" , "Heading2" , etc. Include outlineLevel (H1 = 0, H2 = 1, ...), otherwise TOC may not pick up headings. Paragraphs vs newlines : Do not embed \n in runs to simulate line breaks; create separate Paragraph elements. Lists : Do not manually insert Unicode bullet characters as plain text. Use numbering.config with LevelFormat.BULLET / LevelFormat.DECIMAL . Numbering continuity depends on reference : same reference continues; different reference restarts. Tables (critical rendering rules) : Always use WidthType.DXA (percent widths can break in Google Docs). Set table width and columnWidths ; the sum of columnWidths must equal table width. Set each cell width to match its corresponding column width (required for consistent rendering). Cell margins are internal padding and do not add to width; they reduce usable content area. For shading, prefer ShadingType.CLEAR to avoid unexpected black backgrounds. Images : ImageRun requires a valid type (e.g., png , jpg ) and altText fields. Page breaks : PageBreak must be inside a Paragraph (or use pageBreakBefore: true ). When Not to Use Do not proceed when required input files, identifiers, parameters, or context are missing — ask the user to provide them first. Do not assume capabilities beyond this skill's declared scope when the user requests external operations or inferences. Do not proceed without user confirmation when overwriting existing results, executing high-cost batch operations, or expanding task scope. Required Inputs Field Required Format/Source Example If Missing User task description Yes Text Research question, writing goal, analysis objective Stop and ask user to provide Primary input material Depends on task Text, file path, ID, table, or literature PMID, PDF, CSV, DOCX, keywords, etc. Specify which material type is missing Output preference No Text Language, format, target journal, template Use skill default format Output Contract Primary output: Structured result or target file aligned with this skill's objective. Optional output: Intermediate check notes, issue list, supplementary suggestions, or generated file paths. Format requirement: Unless the user specifies otherwise, prefer stable, reviewable Markdown or JSON; if the skill's bundled script requires a fixed format, use that format. If partially complete: Must explicitly mark as PARTIAL and state which steps are completed and which remain. Failure Handling Missing critical input: Explicitly state which fields, files, or identifiers are missing and pause. Script, template, or resource execution failure: Report the failing step, likely cause, and recovery suggestions — do not silently degrade. Partial completion only: Return the verified portion first, then list remaining blockers and suggested next steps. User Checkpoints Before executing batch processing, overwriting files, long-running searches, or multi-stage generation, confirm scope and output format with the user. Before proceeding when a key judgment is ambiguous, evidence is insufficient, or the workflow is entering the next stage, confirm with the user. Input Validation This skill accepts requests that match the documented purpose of word-read-write and include enough context to complete the workflow safely. Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond: word-read-write only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill. Quick Validation Check that key scripts, templates, or reference file paths this skill depends on exist. Check that the final output contains the core fields, sections, or files specified for this task. Check that results clearly mark assumptions, limitations, and incomplete items.
