+# Document Skills
+
+## The problem
+
+Users keep asking coding agents for document deliverables — a Word report, a PDF handout, a slide
+deck, a data workbook — and get unreliable results: ZIP files rewritten by hand and corrupted,
+spreadsheets where formulas were typed as text, slide decks that no viewer opens, PDFs that are a
+stack of screenshots instead of text. Office and PDF documents are container formats with strict
+internal contracts, and an agent without format knowledge breaks them silently.
+
+This Plugin installs four namespaced workbench Skills — `document-skills-docx`,
+`document-skills-pdf`, `document-skills-pptx`, and `document-skills-xlsx` — that route each task
+to the right standard tool (python-docx, python-pptx, openpyxl, pypdf, ReportLab, PyMuPDF),
+enforce the container contracts (valid ZIP, correct content types, calculated dimensions), and
+verify output before it is handed back. The namespaced IDs avoid overriding host-provided Skills
+with generic names such as `docx`, `pdf`, `pptx`, or `xlsx`.
+
+## Try it
+
+```text
+Use the document-skills plugin: open sales-2024.xlsx, add a sheet "Summary" with per-region
+totals computed by formula, a bar chart of the top 5 products, and currency formatting.
+```
+
+Expected result: the agent loads the workbook with openpyxl, inspects sheet names, headers, and
+dtypes, writes `SUMIF`/`COUNTIF` formulas (not pasted values), adds a native `BarChart` anchored
+to the new sheet, applies number formats, and reports the cell ranges it changed.
+
+```text
+Use the document-skills plugin: create a PDF one-pager "Q3 launch checklist" from this outline
+with a title block and a two-column checklist that fits exactly one A4 page.
+```
+
+Expected result: the agent generates the page with ReportLab flowables on an A4 canvas, measures
+the checklist blocks, and confirms with pypdf that the output is exactly 1 page with extractable
+text — not a screenshot.
+
+## What the Skills do
+
+Shared spine (all four Skills follow it):
+
+1. Classify the request as **create**, **read**, **edit**, or **review**.
+2. Check tool availability first and report missing dependencies instead of improvising.
+3. Follow format-specific rules (packages below).
+4. Run the post-generation verification checklist; fix and re-verify until it passes.
+5. Report the output path, the page/sheet/slide inventory, and any remaining caveats.
+
+Per format:
+
+- **document-skills-docx** — create with python-docx from a heading outline; use python-docx first
+  for routine structural edits (paragraphs, tables, images, styles, and text runs), and reserve
+  direct OOXML surgery for fields, tracked changes, or package features python-docx cannot express;
+  extract text with python-docx or `pandoc -t markdown`; postcheck with python-docx re-open and
+  `soffice --headless --convert-to` PDF smoke test when LibreOffice is present. Depth references:
+  CJK typography (east-asian font slots, 字号 table, char-based indents, GB/T 9704 page geometry)
+  and scene patterns (academic paper, resume, official document, contract).
+- **document-skills-xlsx** — openpyxl for reading, editing, styling, and native charts; formulas as
+  formulas, never as pasted results; `data_only=True` only for reading cached values; date/number
+  formats applied explicitly; recalculation contract documented (openpyxl writes formulas, the
+  Skill sets `fullCalcOnLoad` so even manual-calc workbooks recalculate when a viewer opens them).
+  Depth references: conditional formatting rules, structured tables, and honest pivot-style
+  aggregation (openpyxl cannot create pivot tables; the reference gives the formula-sheet,
+  frozen-values, and user-template routes).
+- **document-skills-pptx** — python-pptx to build decks (7 common slide patterns: title, agenda,
+  bullet, two image+text, table, chart, quote/closing); edit only named, existing shapes, never
+  blind rewriting of the whole XML; text measured against shape width with font-size reduction
+  rules; presentation-level verification via `python-pptx` re-open plus a rendered PDF smoke test
+  when LibreOffice is available.
+- **document-skills-pdf** — creation prefers ReportLab (real, selectable text with flowable
+  structure) over HTML-to-print paths; extraction (text, coordinates, tables, images) and
+  rasterization use PyMuPDF, while pypdf is reserved for page-level transforms such as split,
+  merge, rotate, watermark, encryption, and forms; an explicit one-tool-per-job table prevents
+  accidental API mixing. Note: ReportLab output is not tagged PDF/UA — when the user needs an
+  accessible (screen-reader-ready) PDF, the PDF Skill says to report that limitation honestly
+  instead of claiming accessibility.
+
+## Verification-first output
+
+Every Skill ends with the same rule: do not hand back a file you have not re-opened. The checklists
+are specific (re-open the archive, confirm the sheet count and formula presence, confirm the slide
+count, confirm page count and text extraction) and the Skills require reporting what was verified
+versus what was assumed.
+
+The [`tests/`](tests/) directory ships one runnable fixture script per format covering the
+snippets with the worst silent-failure modes (PDF AcroForm clone-and-fill, watermark write,
+encrypted extraction, CMYK conversion, soft masks; PPTX run-preserving edits, table-cell locating,
+actual content extraction, grouped shapes, script-aware per-master themes; XLSX dialect sniffing,
+array formulas, streamed extension checks, structural-reference audits; DOCX bounded package review,
+content controls, per-run glyph checks, guarded replacement, and a LibreOffice-rendered numbering
+restart). Each script is self-contained and exits non-zero on failure.
+
+These heavyweight integration fixtures are intentionally not part of the repository-wide
+`npm run check`. To run the same gate locally from this plugin directory:
+
+```bash
+python -m pip install -r tests/requirements-fixtures.txt
+node --test tests/fixtures.integration.mjs
+```
+
+LibreOffice (`soffice`) must be available for the rendering checks. The path-filtered
+`.github/workflows/document-skills.yml` workflow installs the pinned Python environment and
+LibreOffice, then runs this fixture gate only when the document-skills plugin or its workflow
+changes.
+
+## Requirements
+
+- Python 3.9+ with `python-docx`, `python-pptx`, `openpyxl`, `pypdf`, `reportlab`,
+  `pymupdf` (`pip install python-docx python-pptx openpyxl pypdf reportlab pymupdf`).
+- Optional: LibreOffice (`soffice`) for PDF smoke tests of DOCX/PPTX output; `pandoc` for
+  markdown extraction from DOCX.
+- Works on Windows, macOS, and Linux. All commands are given in cross-platform form; the Skills
+  say how to resolve the skill directory path on each platform.
+
+## Data and network
+
+- No network access. All processing is local file conversion and generation.
+- No credentials required.
+- The Skills only read and write document files the user points at; temporary files go to the
+  system temp directory and are cleaned up.
