officecli

name	officecli
description	Create, analyze, proofread, and modify Office documents (.docx, .xlsx, .pptx) using the officecli CLI tool. First read the complete builtin://officecli/SKILL.md to get skillToken; this SKILL.md read does not require skillToken. Calls without the correct skillToken will fail and must be retried.

officecli

AI-friendly CLI for .docx, .xlsx, .pptx. Single binary, no dependencies, no Office installation needed.

IMPORTANT: How to Use This Tool

This is a dedicated built-in tool named officecli. You MUST follow these rules:

1. Do NOT use shell_command to run officecli commands. The gateway will block any attempt to run officecli through shell_command. Always use this officecli tool directly.

2. Executing commands (skillToken required):

   • Every exec value MUST start with the officecli prefix.
   • You MUST include the skillToken returned from reading this skill.
   • Example: officecli({"exec": "officecli create report.docx", "skillToken": "<token>"})

3. The exec field always requires the officecli command prefix. Do NOT omit it.

   • Correct: "exec": "officecli help"
   • Correct: "exec": "officecli create file.docx"
   • Wrong: "exec": "help"
   • Wrong: "exec": "create file.docx"

4. Command snippets in this skill are CLI syntax. When this skill shows officecli ... in a code block, execute that command by putting the full line in the built-in tool's exec field with the required skillToken.

Prerequisites

The officecli binary must be installed and available in PATH before this tool can be enabled. Use officecli --version to verify. If not installed, enable it via the admin UI or install manually from https://github.com/iOfficeAI/OfficeCLI/releases.

Strategy

L1 (read) -> L2 (DOM edit) -> L3 (raw XML). Always prefer higher layers. Add --json for structured output.

Before document work, check Specialized Skills near the bottom of this file. Generic decks, pitch decks, Morph decks, academic papers, financial models, and dashboards need their own officecli load_skill <name> rules before creating or heavily editing the artifact. The base skill explains commands; the specialized skill explains document quality.

---

Help System (IMPORTANT)

When unsure about property names, value formats, or command syntax, ALWAYS run help instead of guessing. One help query beats guess-fail-retry loops.

officecli help is equivalent to officecli --help, and officecli <cmd> --help is equivalent to officecli help <cmd>.

Gateway execution examples:

officecli({"exec": "officecli help", "skillToken": "<token>"})
officecli({"exec": "officecli help docx", "skillToken": "<token>"})
officecli({"exec": "officecli help docx paragraph", "skillToken": "<token>"})
officecli({"exec": "officecli help docx set paragraph", "skillToken": "<token>"})
officecli({"exec": "officecli help pptx shape --json", "skillToken": "<token>"})

CLI syntax examples:

officecli help                                  # All commands + global options + schema entry points
officecli help docx                             # List all docx elements
officecli help docx paragraph                   # Full schema: properties, aliases, examples, readbacks
officecli help docx set paragraph               # Verb-filtered: only props usable with `set`
officecli help docx paragraph --json            # Structured schema (machine-readable)

Format aliases: word -> docx, excel -> xlsx, ppt/powerpoint -> pptx. Verbs: add, set, get, query, remove.

---

Resident Mode

Every command auto-starts a resident on first access when available, with a short idle timeout, so file-lock conflicts are automatically avoided. Explicit open/close is still recommended for longer sessions:

officecli({"exec": "officecli open report.pptx", "skillToken": "<token>"})
officecli({"exec": "officecli set report.pptx ...", "skillToken": "<token>"})
officecli({"exec": "officecli close report.pptx", "skillToken": "<token>"})

officecli open report.docx       # explicitly keep in memory
officecli set report.docx ...    # no file I/O overhead
officecli close report.docx      # save and release

Opt out of auto-start with OFFICECLI_NO_AUTO_RESIDENT=1.

---

Quick Start

PPT:

officecli({"exec": "officecli create slides.pptx", "skillToken": "<token>"})
officecli({"exec": "officecli add slides.pptx / --type slide --prop title=\"Q4 Report\" --prop background=1A1A2E", "skillToken": "<token>"})
officecli({"exec": "officecli add slides.pptx '/slide[1]' --type shape --prop text=\"Revenue grew 25%\" --prop x=2cm --prop y=5cm --prop font=Arial --prop size=24 --prop color=FFFFFF", "skillToken": "<token>"})

Word:

officecli({"exec": "officecli create report.docx", "skillToken": "<token>"})
officecli({"exec": "officecli add report.docx /body --type paragraph --prop text=\"Executive Summary\" --prop style=Heading1", "skillToken": "<token>"})
officecli({"exec": "officecli add report.docx /body --type paragraph --prop text=\"Revenue increased by 25% year-over-year.\"", "skillToken": "<token>"})

Excel:

officecli({"exec": "officecli create data.xlsx", "skillToken": "<token>"})
officecli({"exec": "officecli set data.xlsx /Sheet1/A1 --prop value=\"Name\" --prop bold=true", "skillToken": "<token>"})
officecli({"exec": "officecli set data.xlsx /Sheet1/A2 --prop value=\"Alice\"", "skillToken": "<token>"})

---

PowerPoint Quality Workflow

For .pptx, first load exactly one matching specialized skill:

officecli({"exec": "officecli load_skill pptx", "skillToken": "<token>"})

Then follow the rules it prints. At minimum:

• Set explicit geometry on every non-placeholder shape: x, y, w/width, h/height.
• Set explicit typography on text shapes: font, size, color, and alignment where supported.
• Use one idea per slide. Split dense bullet slides instead of shrinking text.
• Every content slide should include a non-text visual: shape system, picture, chart, icon, table, or diagram.
• Add speaker notes on content slides with --type notes when generating a real deck.
• Verify after generation with view outline, view stats --json, view issues --json, and a rendered preview (view html or view screenshot).
• Treat text overflow and off-slide geometry as blocking issues. Fix them before declaring the file done.

Common failure mode: creating only a title and one default text box per slide produces a valid PowerPoint file, but not a designed presentation. Default text boxes start at x=0cm y=0cm and 10cm x 5cm; they usually look unplaced and can overlap or overflow.

---

REQUIRED: WPS Compatibility Fix

OfficeCLI writes <Application>OfficeCLI/x.x.x</Application> into docProps/app.xml when creating files. WPS Office does not recognize this application identifier and will refuse to open the file ("format not recognized").

After every officecli create, you MUST run this cleanup step:

officecli raw-set <file> docProps/app.xml --xpath "//ap:Application" --action delete

Example full flow:

officecli({"exec": "officecli create report.docx", "skillToken": "<token>"})
officecli({"exec": "officecli raw-set report.docx docProps/app.xml --xpath \"//ap:Application\" --action delete", "skillToken": "<token>"})

This applies to all formats (.docx, .xlsx, .pptx). Do NOT skip this step.

---

L1: Create, Read & Inspect

officecli create <file>               # Create blank .docx/.xlsx/.pptx (type from extension)
officecli view <file> <mode>          # outline | stats | issues | text | annotated | html
officecli get <file> <path> --depth N # Get a node and its children [--json]
officecli query <file> <selector>     # CSS-like query
officecli validate <file>             # Validate against OpenXML schema

view modes

Mode	Description	Useful flags
outline	Document structure
stats	Statistics (pages, words, shapes)
issues	Formatting/content/structure problems	--type format|content|structure, --limit N
text	Plain text extraction	--start N --end N, --max-lines N
annotated	Text with formatting annotations
html	Static HTML snapshot, same renderer as watch, no server needed	--browser, --page N (docx), --start N --end N (pptx)
screenshot / svg / pdf / forms	PNG via headless browser / SVG (pptx slide) / PDF via exporter plugin / form-fields JSON via format-handler plugin	-o, --screenshot-width/-height, pptx --grid N

Use view html for one-shot snapshots (CI artifacts, archival, diffing); use watch when you need live refresh or browser-side click-to-select.

Useful render checks:

officecli view <file> html -o preview.html
officecli view <file> screenshot -o slide.png
officecli view <file> issues --json

get

Any XML path via element localName. Use --depth N to expand children. Add --json for structured output. Default text output is grep-friendly: path (type) "text" key=val key=val ...

officecli get report.docx '/body/p[3]' --depth 2 --json
officecli get slides.pptx '/slide[1]' --depth 1          # list all shapes on slide 1
officecli get data.xlsx '/Sheet1/B2' --json

Stable ID Addressing

Elements with stable IDs return @attr=value paths instead of positional indices. Prefer these in multi-step workflows because positional indices shift on insert/delete, while stable IDs do not.

/slide[1]/shape[@id=550950021]                    # PPT shape
/slide[1]/table[@id=1388430425]/tr[1]/tc[2]       # PPT table
/body/p[@paraId=1A2B3C4D]                         # Word paragraph
/comments/comment[@commentId=1]                    # Word comment

PPT also accepts @name= (for example shape[@name=Title 1]), with morph !! prefix awareness. Elements without stable IDs (slide, run, tr/tc, row) fall back to positional indices.

query

CSS-like selectors: [attr=value], [attr!=value], [attr~=text], [attr>=value], [attr<=value], :contains("text"), :empty, :has(formula), :no-alt.

officecli query report.docx 'paragraph[style=Normal] > run[font!=Arial]'
officecli query slides.pptx 'shape[fill=FF0000]'

---

Watch & Interactive Selection

Live HTML preview that auto-refreshes on every file change. Browsers can click, shift-click, or box-drag to select shapes; the CLI can read the current browser selection and act on it.

officecli watch <file> [--port N]      # Start preview server (default port 26315)
officecli unwatch <file>               # Stop
officecli goto <file> <path>           # Scroll watching browser(s) to element (docx: p / table / tr / tc)

Open the printed http://localhost:N URL. Click to select; shift/cmd/ctrl-click to multi-select; drag from empty space to box-select. PPT/Word use blue outline; Excel uses native-style green selection (double-click cell to edit inline; drag a chart to reposition).

get <file> selected - read what the user clicked

officecli get <file> selected [--json]

Returns DocumentNodes for whatever is currently selected. Empty result if nothing selected. Exit code is nonzero if no watch is running.

# User clicks shapes in the browser, then asks "make these red"
PATHS=$(officecli get deck.pptx selected --json | jq -r '.data.Results[].path')
for p in $PATHS; do officecli set deck.pptx "$p" --prop fill=FF0000; done

Key properties

• Selection survives file edits. Paths use stable @id= form.
• All connected browsers share one selection. Last-write-wins.
• Same-file single-watch. A given file can have only one watch process at a time.
• Group shapes select as a whole. Drilling into individual children of a group is not supported in v1.
• Coverage: .pptx shapes/pictures/tables/charts/connectors/groups; .docx top-level paragraphs and tables. Inherited layout/master decorations and Word nested elements (table cells, run-level) are not addressable. .xlsx does not emit data-path; mark/selection on xlsx always resolve stale=true.

Marks - edit proposals waiting for review

Use mark when changes need human review BEFORE they hit the file. Marks live in the watch process only; a separate set pipeline applies accepted ones. For one-shot changes use set directly; for permanent file annotations use add --type comment (Word native).

officecli mark <file> <path> [--prop find=... color=... note=... tofix=... regex=true] [--json]
officecli unmark <file> [--path <p> | --all] [--json]
officecli get-marks <file> [--json]

Props: find (literal or regex when regex=true; raw form find='r"[abc]"'), color (hex / rgb(...) / 22 named whitelist), note, tofix (drives apply pipeline). Path must be data-path format from watch HTML; see subskills for full pipeline.

---

L2: DOM Operations

set - modify properties

officecli set <file> <path> --prop key=value [--prop ...]

Any XML attribute is settable via element path (found via get --depth N), even attributes not currently present. Without find=, set applies format to the entire element.

Value formats:

Type	Format	Examples
Colors	Hex (with/without #), named, RGB, theme	FF0000, #FF0000, red, rgb(255,0,0), accent1..accent6
Spacing	Unit-qualified	12pt, 0.5cm, 1.5x, 150%
Dimensions	EMU or suffixed	914400, 2.54cm, 1in, 72pt, 96px

Dotted-attr aliases are accepted on shape/run/paragraph/table/row/cell/section/styles, for example --prop font.color=red --prop font.bold=true --prop font.size=14pt. Run officecli help <fmt> <element> for the full list.

find - format or replace matched text

Use find= with set to target specific text for formatting or replacement. Format props are separate --prop flags; do not nest them.

# Format matched text (auto-splits runs)
officecli set doc.docx '/body/p[1]' --prop find=weather --prop bold=true --prop color=red

# Regex matching
officecli set doc.docx '/body/p[1]' --prop 'find=\d+%' --prop regex=true --prop color=red

# Replace text (use `/` for whole-document scope)
officecli set doc.docx / --prop find=draft --prop replace=final

# PPT: same syntax, different paths
officecli set slides.pptx / --prop find=draft --prop replace=final

Path controls search scope: / = whole document, /body/p[1] or /slide[N]/shape[M] = specific element, /header[1] / /footer[1] = headers/footers.

Notes:

• Case-sensitive by default. Case-insensitive: --prop 'find=(?i)error' --prop regex=true.
• Matches work across run boundaries.
• No match = silent success. --json includes "matched": N.
• Excel: only find + replace is supported; find + format props are not.

add - add elements or clone

officecli add <file> <parent> --type <type> [--prop ...]
officecli add <file> <parent> --type <type> --after <path> [--prop ...]   # insert after anchor
officecli add <file> <parent> --type <type> --before <path> [--prop ...]  # insert before anchor
officecli add <file> <parent> --type <type> --index N [--prop ...]        # 0-based position (legacy)
officecli add <file> <parent> --from <path>                               # clone existing element

--after, --before, and --index are mutually exclusive. No position flag means append to end.

Element types (with aliases):

Format	Types
pptx	slide (incl. hidden), shape (font.latin/ea/cs, direction=rtl, underline.color, effective.X+effective.X.src; arrow alias for rightArrow; slideMaster/slideLayout typed add/set/remove), picture (SVG, brightness/contrast/glow/shadow, rotation, link, tooltip), chart (direction=rtl, pieOfPie, barOfPie, axisLine/gridline per-attr setters, animation+chartBuild=byCategory|bySeries, line dropLines/hiLowLines/upDownBars, anchor=x,y,w,h shorthand), table (cell direction=rtl, fill/background, built-in PowerPoint style catalogue, /col[C] get + swap/copyFrom, row/col Move/CopyFrom), row (tr), connector (from/to accept @name=, startshape/endshape SetByPath), group (link, tooltip, deep walk by get/query/add/remove), video/audio (loop, autoStart alias), equation, notes (direction=rtl, lang), comment (legacy + modern p188 threaded round-trip), animation (15 emphasis + 16 exit presets, multi-effect chains, motion-path presets, repeat/restart/autoReverse, chart animations), transition (12 p15 presets + morph/p14), paragraph (para), run, zoom, ole (preview=, full dump round-trip via add-part+raw-set), placeholder (phType=...), model3d (rotation=ax,ay,az; full dump round-trip), smartart (dump round-trip via add-part).
docx	paragraph (direction/font.latin/ea/cs, bold.cs/italic.cs/size.cs, lang.latin/ea/cs, wordWrap, framePr.*, tabs shorthand), run (lang slots, direction, underline.color, position half-pts, revision.type=ins|del|format|moveFrom|moveTo + revision.action=accept|reject with .author/.date, /revision[@author=X] selector for filtered accept/reject), table (direction=rtl, hMerge, virtual column ops: add/remove/move/copyfrom on /body/tbl[N]/col), row (tr), cell (td), image, header/footer (direction), section (pageNumFmt full enum, direction=rtl, rtlGutter, pgBorders=box), bookmark, comment, footnote, endnote, formfield, sdt, chart, equation, field (28 types), hyperlink, style (direction, indents, pbdr, lineSpacing on Add/Set), toc, watermark, break, ole, num/abstractNum/lvl, tab, textbox/shape (full Add+Get; geometry, fill, line, wrap, alt, anchor). docDefaults.rtl, autoHyphenation, get / exposes locale + /comments /footnotes /endnotes. create --minimal for raw OOXML scaffolding.
xlsx	sheet (visible/hidden/veryHidden, print margins, printTitleRows/Cols, rightToLeft sheetView, cascade-aware rename), row (c{N}= cell-content shorthand; add accepts --from /Sheet/col[L]; formula-ref rewrite on insert), col (formula-ref rewrite, named-range follow on move), cell (type=richtext+runs, merge=range/sweep, direction=rtl, phonetic; --shift left|up on remove, shift=right|down on add; formula auto-detect; OFFSET/INDIRECT in calc), chart (per-axis RTL/title, anchor=x,y,w,h, pareto), image (SVG), comment (direction=rtl), table (listobject), namedrange (definedname, volatile, [@name=X]; formula-body inlined at parse), pivottable (cache CoW + cross-pivot sharing, labelFilter, topN, fillDownLabels, calculatedField), sparkline, validation, autofilter, shape, textbox, CF (databar/colorscale/iconset/formulacf/cellIs/topN/aboveAverage), ole, csv. Query supports merge/mergedrange. Workbook: password. Shape selector enumerates leaves inside grpSp.

Pivot tables (xlsx)

officecli add data.xlsx /Sheet1 --type pivottable \
  --prop source="Sheet1!A1:E100" --prop rows=Region,Category \
  --prop cols=Year --prop values="Sales:sum,Qty:count" \
  --prop grandTotals=rows --prop subtotals=off --prop sort=asc

Key props: rows, cols, values (Field:func[:showDataAs]), filters, source, position, layout (compact/outline/tabular), repeatLabels, blankRows, aggregate, showDataAs (percent_of_total/row/col, running_total), grandTotals, subtotals, sort. Aggregators: sum, count, average, max, min, product, stdDev, stdDevp, var, varp, countNums. Date columns auto-group. Run officecli help xlsx pivottable for full schema.

Document-level properties (all formats)

officecli set doc.docx / --prop docDefaults.font=Arial --prop docDefaults.fontSize=11pt
officecli set doc.docx / --prop protection=forms --prop evenAndOddHeaders=true
officecli set data.xlsx / --prop calc.mode=manual --prop calc.refMode=r1c1
officecli set slides.pptx / --prop defaultFont=Arial --prop show.loop=true --prop print.what=handouts

Run officecli help <format> / for all document-level properties (docDefaults, docGrid, CJK spacing, calc, print, show, theme, extended).

Sort (xlsx)

officecli set data.xlsx /Sheet1 --prop sort="C desc" --prop sortHeader=true
officecli set data.xlsx '/Sheet1/A1:D100' --prop sort="A asc" --prop sortHeader=true

Format: COL DIR[, COL DIR ...]. Rejects ranges with merged cells or formulas. Sidecar metadata (hyperlinks, comments, conditional formatting, drawings) follows rows automatically.

Text-anchored insert (--after find:X / --before find:X)

Locate an insertion point by text match within a paragraph. Inline types (run, picture, hyperlink) insert within the paragraph; block types (table, paragraph) auto-split it. PPT only supports inline.

# Word: inline run after matched text
officecli add doc.docx '/body/p[1]' --type run --after find:weather --prop text=" (sunny)"

# Word: block table after matched text (auto-splits paragraph)
officecli add doc.docx '/body/p[1]' --type table --after "find:First sentence." --prop rows=2 --prop cols=2

Clone

officecli add <file> / --from '/slide[1]' copies with all cross-part relationships.

move, swap, remove

officecli move <file> <path> [--to <parent>] [--index N] [--after <path>] [--before <path>]
officecli swap <file> <path1> <path2>
officecli remove <file> '/body/p[4]'

When using --after or --before, --to can be omitted because the target container is inferred from the anchor.

batch - multiple operations in one save cycle

Continues on error by default and returns exit 1 if any item fails. Use --stop-on-error to abort on the first failure. --force is the docx-protection bypass.

officecli dump <file> [<path>] emits a replayable batch JSON for round-trip. .docx has full coverage; .pptx covers text/tables/pictures/charts/notes/theme plus OLE/3D/video/audio/SmartArt/morph/p15 transitions via raw-set passthrough. Path defaults to / (whole document); pass a subtree path (/body, /body/p[N], /body/tbl[N], /theme, /settings, /numbering, /styles) to scope the dump. officecli refresh <file.docx> recalculates TOC page numbers / PAGE / cross-references after replay. officecli plugins list extends support to .doc, .hwpx, and .pdf export.

echo '[
  {"command":"set","path":"/Sheet1/A1","props":{"value":"Name","bold":"true"}},
  {"command":"set","path":"/Sheet1/B1","props":{"value":"Score","bold":"true"}}
]' | officecli batch data.xlsx --json

officecli batch data.xlsx --commands '[{"op":"set","path":"/Sheet1/A1","props":{"value":"Done"}}]' --json
officecli batch data.xlsx --input updates.json --force --json

Supports: add, set, get, query, remove, move, swap, view, raw, raw-set, validate. Fields: command (or op), path, parent, type, from, to, index, after, before, props, selector, mode, depth, part, xpath, action, xml.

---

L3: Raw XML

Use when L2 cannot express what you need. No xmlns declarations needed; prefixes are auto-registered.

officecli raw <file> <part>                          # view raw XML
officecli raw-set <file> <part> --xpath "..." --action replace --xml '<w:p>...</w:p>'
officecli add-part <file> <parent>                   # create new document part (returns rId)

raw-set actions: append, prepend, insertbefore, insertafter, replace, remove, delete, setattr. The project WPS cleanup flow uses delete for docProps/app.xml; when in doubt, run officecli help <format> raw for available parts and action names.

---

Common Pitfalls

Pitfall	Correct Approach
Using shell_command for officecli	Use this officecli tool directly
Omitting officecli prefix in exec	Always write "exec": "officecli ..."
--name "foo"	Use --prop name="foo"; all attributes go through --prop
Unquoted [N] paths in zsh/bash	Always quote: '/slide[1]' or "/slide[1]"
PPT shape[1] for content	shape[1] is typically the title placeholder. Use shape[2]+ for content shapes
/shape[myname]	Name indexing not supported. Use numeric index or @name= (PPT only)
Guessing property names	Run officecli help <format> <element> to see exact names
Modifying an open file	Close the file in Office/WPS first
\n in shell strings	Use \\n for newlines in --prop text="..."; use batch JSON for real newline characters
$ in shell text	--prop text="$15M" strips $15. Use single quotes: --prop text='$15M', or heredoc batch
Bullet-only PPT slides	Load pptx skill and create explicit layout, visuals, typography, and notes
Default PPT text box placement	Set x, y, width, height, font size, and colors explicitly

---

Specialized Skills

officecli load_skill <name> prints extra rules for a specific artifact type. Load one specialized skill per artifact before creating or substantially editing it.

Loading rule:

• Pick the most specific match in "When to use"; if none fits, load the format default (word / pptx / excel).
• Scenes already contain the format default's rules. Load one skill per artifact; never stack multiple specialized skills for the same artifact.
• Loaded rules persist across turns; do not re-load each reply.
• Two distinct artifacts require two separate loads.

Word (.docx)

Name	When to use
word	Reports, letters, memos, proposals, generic documents
academic-paper	Journal / conference / thesis: APA / Chicago / IEEE / MLA citations, equations, SEQ + PAGEREF cross-refs, multi-column journal layout, bibliography. NOT for business reports or letters (route those to word)

PowerPoint (.pptx)

Name	When to use
pptx	Generic decks: board reviews, sales decks, all-hands, product launches
pitch-deck	Fundraising only: seed / Series A-C / SAFE / convertible / strategic raise. NOT for sales / product / board decks (route those to pptx)
morph-ppt	Cinematic Morph-animated presentations. NOT for static decks (route those to pptx)
morph-ppt-3d	3D Morph: GLB models, camera moves, depth. NOT for 2D-only Morph (route those to morph-ppt)

Excel (.xlsx)

Name	When to use
excel	Generic workbooks, formulas, pivots, trackers
financial-model	Financial models, scenarios, projections. NOT for general data analysis (route those to excel)
data-dashboard	CSV/tabular data -> KPI / analytics / executive dashboards with charts and sparklines. NOT for raw data tracking (route those to excel)

Example: a fundraising deck task -> officecli load_skill pitch-deck -> use the printed rules.

---

Notes

• Paths are 1-based (XPath convention): '/body/p[3]' = third paragraph.
• --index is 0-based (array convention): --index 0 = first position.
• Excel exception: for add --type row and add --type col, --index N is 1-based (matches OOXML RowIndex / column letter index). --index 5 inserts at row 5 / column 5.
• After modifications, verify with validate and/or view issues.
• When unsure, run officecli help <format> <element> instead of guessing.

---

Companion Tools

The officecli skill only owns .docx / .xlsx / .pptx documents. Any secondary files (Markdown notes, JSON dumps from officecli view --json, unit fixtures, extracted plain text) must go through the other bundled skills:

• Persist or rewrite secondary files with multi_edit_file so the gateway has a reviewable diff and path allowlist enforcement; do not use shell_command redirection, Set-Content, or here-documents for that.
• Inspect the current contents of those files with read_file so output is line-numbered and size-capped; do not use shell_command with cat, Get-Content, type, sed, head, or tail.
• Never wrap an officecli invocation inside shell_command. The gateway rejects that path. Call this officecli tool directly.
