OfficeCLI Word-Form Skill

This skill is INDEPENDENT, not a scene layer on docx. A form's payload — <w:sdt> controls, <w:ffData> legacy fields, <w:fldChar> mail-merge, documentProtection — is a distinct element class from docx's paragraph/heading/style primitives. Its QA is different too: docx's Delivery Gate cares about visual layout and live PAGE fields, this skill's cares about data plumbing (protection enforced / alias+tag / items injected / name ≤ 20 / no underscore anti-pattern). Reverse handoff: if the user's document has no fillable fields (report, letter, memo, thesis, proposal), route to officecli-docx or a docx scene skill — don't use this one.

BEFORE YOU START (CRITICAL)

If officecli is not installed:

macOS / Linux

if ! command -v officecli >/dev/null 2>&1; then
    curl -fsSL https://d.officecli.ai/install.sh | bash
fi

Windows (PowerShell)

if (-not (Get-Command officecli -ErrorAction SilentlyContinue)) {
    irm https://d.officecli.ai/install.ps1 | iex
}

Verify: officecli --version

If officecli is still not found after first install, open a new terminal and run the verify command again.

If the install command above fails (e.g. blocked by security policy, no network access, or insufficient permissions), install manually — download the binary for your platform from https://github.com/iOfficeAI/OfficeCLI/releases — then re-run the verify command.

Help-First Rule

This skill teaches what a real form needs, not every CLI flag. When a prop / alias / enum is uncertain, consult help BEFORE guessing: officecli help docx [element] [--json] (e.g. sdt, formfield, field). Help is pinned to the installed CLI version and is authoritative — when this skill and help disagree, help wins (the prop set on sdt in particular has grown over time; trust help docx sdt, not a hardcoded list).

Mental Model & Inheritance

A Word form is a .docx plus four OpenXML payload layers plain-docx skills do not touch: <w:sdt> content controls (types: text / richtext / dropdown / combobox / date / picture / group), <w:ffData> legacy FormField (still the only way to get a real checkbox — SDT type=checkbox is not implemented), <w:fldChar> complex fields (MERGEFIELD, REF, PAGEREF, SEQ, IF — template-time, not user-fill), and documentProtection (the lock that makes non-field text read-only in Word — and, on the CLI, protection=forms locks non-field content edits (those need --force or raw-set) but still allows form-field (SDT) edits, which is the point of forms protection).

No inheritance from docx v2. docx's Delivery Gate (cover-fill %, live-PAGE check) does NOT apply — form QA is view forms + query sdt alias+tag + protectionEnforced.

Reverse handoff to docx. Route back to officecli-docx for reports / letters / memos / thesis / pitch decks / any document with no editable fields. Use this skill when the document's purpose is data capture or template merge.

Shell & Execution Discipline

One command at a time. Read output before the next. OfficeCLI is incremental — every add / set / remove immediately mutates the file. All recipes below use FILE=form.docx as a shell variable.

Three shell-escape layers:

1. Quote every path with [N] — zsh/bash glob-expand brackets. officecli get "$FILE" /body/sdt[1] fails with no matches found. Correct: officecli get "$FILE" '/body/sdt[1]'.
2. Single-quote any prop containing $ — "Total: $50,000" becomes "Total: ,000" after $50 variable expansion. Correct: 'Total: $50,000'.
3. --after find:<text> uses outer single quotes, never inner double quotes — --after find:"Client Signature:" makes the quotes part of the search string; match fails. Correct: --after 'find:Client Signature:'.

WARNING: UNSUPPORTED (exit 2) is a silently-wrong element. The CLI created the element without the rejected prop (exit 2 = ran with caveats; only when every prop is refused does --json report success: false). Any UNSUPPORTED in your build log means a prop name the current CLI does not accept on that element — stop, check help docx <element> for the right prop name (most SDT props such as items/format/lock ARE accepted now; maxlength is not), fix the command, and re-run. Do not ship on top.

protection=forms is the LAST structural command. Once it is set, protection=forms locks non-field content (those edits need --force or raw-set) but still allows form-field (SDT) edits — which is the point of forms protection. A non-field content edit (e.g. set /body/p[N] --prop text=) is refused (ERROR: Document is protected … use --force); a form-field edit (e.g. set /body/sdt[N] --prop text= / --prop alias=) succeeds (exit 0). Use Query("editable") to find fillable fields. So finish all non-field (static layout) edits first, then lock; if you must edit static content afterward, pass --force (or temporarily clear protection, edit, re-lock).

--after find: micro-playbook

--after find:<text> matches the first occurrence. Bad anchor = wrong insertion location, expensive to debug. Three rules:

1. Anchor must be globally unique. In bilingual contracts "甲方签字" matches both parties — use a unique phrase like "甲方签字（Service Provider）" or full English title.
2. After insert, /body/p[last()] is unreliable — the find insertion changes <w:body> child order. To continue operating on the new paragraph, read its real paraId: officecli query "$FILE" paragraph --json | jq -r '.data.results[-1].format.paraId'.
3. Chinese + full-width parens （） match literally in find, but when unsure, officecli view "$FILE" text | grep -n "锚点" first to confirm the exact bytes in the file.

# Trap: first-match hits 甲方 only, 乙方 missed
officecli add "$FILE" /body --type sdt --after 'find:签字'

# Fix: two signatories, two unique anchors
officecli add "$FILE" /body --type sdt --prop alias=Party_A_Name --prop tag=party_a \
  --after 'find:甲方签字（Service Provider）'
PID_A=$(officecli query "$FILE" paragraph --json | jq -r '.data.results[-1].format.paraId')
officecli add "$FILE" "/body/p[@paraId='$PID_A']" --type sdt --prop alias=Party_A_Title --prop tag=party_a_title

Inline SDT via --after find: is added as a child of the matched paragraph, not as a new paragraph — use this when label + SDT must share a line.

What makes a real form (identity)

A real fillable form requires structured fields + document protection.

Do not simulate fields with underscores. 姓名：_______________ produces zero structured data and leaks past every verification. Always use --type sdt or --type formfield.

Checkbox is formfield, NOT SDT. --type sdt --prop type=checkbox exits 1 (SDT type 'checkbox' is not implemented). Every checkbox in every recipe uses --type formfield --prop type=checkbox.

MERGEFIELD is a separate track. view forms lists SDT + formfield only; query field lists complex fields only. Two disjoint inventories; both valid in one file.

Requirements for Outputs (hard floor)

Every form must satisfy these — Delivery Gate enforces each as an executable check.

1. protection=forms enforced (get $FILE / → protectionEnforced=True).
2. Every SDT has both alias + tag.
3. Every dropdown/combobox has non-empty items=... in view forms.
4. Every date SDT shows the intended format=....
5. Every locked SDT shows lock=sdtLocked / contentLocked / sdtContentLocked as intended.
6. Zero WARNING: UNSUPPORTED in build log.
7. Zero type=checkbox on any SDT.
8. Every formfield name ≤ 20 characters.
9. Zero underscore-line / blank-line placeholders.
10. Field types match user intent (short text / paragraph / fixed list / list+custom / date / boolean).

Three Paths (core decision)

SDT props are first-class on add — confirm the current set with officecli help docx sdt. Today that includes type, tag, alias, text, items, format, lock, placeholder/placeholderText, date.* and the SDT types text / richtext / dropdown / combobox / date / group / picture. So most forms are pure add — no raw-set, no Word template. Two paths remain only for the genuinely-unreachable cases. Pick the path before writing a single command.

Path A — Pure CLI (the default for almost everything)

Use when: any text / richtext / dropdown / combobox / date / picture / group SDT — including its options, date format, and lock. Pass the props straight on add; verify each persists with get '/body/sdt[N]' --json.

# dropdown WITH its options and a non-default date format, in one add each — no raw-set:
officecli add "$FILE" /body --type sdt \
  --prop type=dropdown --prop alias="Department" --prop tag=dept \
  --prop items="Engineering,Finance,HR"
officecli add "$FILE" /body --type sdt \
  --prop type=date --prop alias="Start Date" --prop tag=start \
  --prop format="yyyy年MM月dd日"
# lock works on add AND set:
officecli add "$FILE" /body --type sdt --prop type=text --prop tag=full_name \
  --prop alias="Full Name" --prop text="Enter full name" --prop lock=sdtLocked
# protection comes last, once all fields exist:
# officecli set "$FILE" / --prop protection=forms

Path B — CLI + raw-set bridge (only an attribute help does NOT expose)

Use when: you need an SDT attribute that help docx sdt does not list (e.g. a <w:listItem> whose w:value must differ from its display text, or a sdtPr child with no --prop). raw-set is OfficeCLI's universal OpenXML fallback — officecli --help lists it as a top-level command. For ordinary dropdowns use --prop items= (Path A); raw-set here is the exception, not the rule.

# Display text ≠ stored value — not expressible via items=, so inject the listItems directly:
officecli add "$FILE" /body --type sdt --prop type=dropdown --prop alias="Department" --prop tag=dept
officecli raw-set "$FILE" /document \
  --xpath "//w:sdt[w:sdtPr/w:tag/@w:val='dept']/w:sdtPr/w:dropDownList" \
  --action append \
  --xml '<w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="Engineering" w:value="ENG"/><w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="Finance" w:value="FIN"/>'

Path C — Word template (only what no API reaches)

Use when: a real SDT checkbox (type=checkbox still exits 1 — use a legacy FormField instead, see §Legacy FormField), a placeholderDocPart prompt-text part, or custom richtext appearance / cross-part nesting beyond --prop reach. Picture and grouped SDTs are NO LONGER here — they add fine via Path A.

# One-time in Word: Developer tab → Insert Content Control → Save as template.docx
cp templates/onboarding_with_signature.docx "$FILE"
officecli open "$FILE"
officecli view "$FILE" forms                 # inspect embedded controls + paths
officecli set "$FILE" '/body/sdt[@sdtId=3]' --prop text="Jane Smith"
officecli set "$FILE" / --prop protection=forms

Decision table

Quick Start — Path A + FormField (minimal intake form)

Two SDT text fields, one checkbox, protection. Paste and adapt; this is the smallest form worth shipping.

FILE=intake.docx
officecli close "$FILE" 2>/dev/null; rm -f "$FILE"   # preflight: clear stale resident / prior file (cold-start after CLI upgrade commonly leaks a resident)
officecli create "$FILE"
officecli open "$FILE"

officecli set "$FILE" / --prop title="Employee Onboarding Intake" \
  --prop docDefaults.font="Calibri" --prop docDefaults.fontSize="12pt"

officecli add "$FILE" /body --type paragraph \
  --prop text="Employee Onboarding Intake" --prop style=Heading1 \
  --prop size=20 --prop bold=true --prop spaceAfter=18pt

officecli add "$FILE" /body --type paragraph \
  --prop text="Full Name:" --prop size=11 --prop bold=true --prop spaceAfter=4pt
officecli add "$FILE" /body --type sdt --prop type=text \
  --prop alias="Full Name" --prop tag=full_name --prop text="Enter full name"

officecli add "$FILE" /body --type paragraph \
  --prop text="Start Date:" --prop size=11 --prop bold=true --prop spaceAfter=4pt
officecli add "$FILE" /body --type sdt --prop type=date \
  --prop alias="Start Date" --prop tag=start_date

officecli add "$FILE" /body --type paragraph \
  --prop text="Read and agree to employee handbook" --prop size=11 --prop spaceAfter=4pt
officecli add "$FILE" /body --type formfield \
  --prop type=checkbox --prop name=agree_handbook --prop checked=false

officecli set "$FILE" '/body/sdt[1]' --prop lock=sdtlocked
officecli set "$FILE" '/body/sdt[2]' --prop lock=sdtlocked
officecli set "$FILE" / --prop protection=forms
officecli close "$FILE"
officecli view "$FILE" forms

Path B — raw-set recipes

Three recipes cover almost every complex-attr need on SDT forms.

B1 — Dropdown items (append)

# Skeleton (Path A)
officecli add "$FILE" /body --type sdt --prop type=dropdown \
  --prop alias="Department" --prop tag=dept

# Inject items
officecli raw-set "$FILE" /document \
  --xpath "//w:sdt[w:sdtPr/w:tag/@w:val='dept']/w:sdtPr/w:dropDownList" \
  --action append \
  --xml '<w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="Engineering" w:value="Engineering"/><w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="Finance" w:value="Finance"/><w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="HR" w:value="HR"/>'

# Verify
officecli get "$FILE" '/body/sdt[1]'   # expect: type=dropdown items=Engineering,Finance,HR

Template. Swap <TAG> / <LABEL> / <VALUE> only. xmlns:w=... is required on every root <w:listItem> — raw-set does not inherit namespace prefixes. Chain multiple <w:listItem>s in one call; option order is preserved.

B2 — Combobox items (same as B1, different xpath tail)

officecli add "$FILE" /body --type sdt --prop type=combobox \
  --prop alias="Current Medication" --prop tag=current_med

officecli raw-set "$FILE" /document \
  --xpath "//w:sdt[w:sdtPr/w:tag/@w:val='current_med']/w:sdtPr/w:comboBox" \
  --action append \
  --xml '<w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="Antihypertensives" w:value="Antihypertensives"/><w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="Insulin" w:value="Insulin"/><w:listItem xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" w:displayText="Other (specify)" w:value="Other"/>'

Only difference from B1: w:comboBox vs w:dropDownList in the xpath tail. Combobox lets the user type custom input; dropdown does not.

B3 — Date format (setattr)

officecli add "$FILE" /body --type sdt --prop type=date \
  --prop alias="Contract Start Date" --prop tag=contract_start

# Chinese: yyyy年MM月dd日
officecli raw-set "$FILE" /document \
  --xpath "//w:sdt[w:sdtPr/w:tag/@w:val='contract_start']/w:sdtPr/w:date/w:dateFormat" \
  --action setattr \
  --xml "w:val=yyyy年MM月dd日"

# US:    w:val=MM/dd/yyyy
# ISO:   w:val=yyyy-MM-dd  (already the default)
# Long:  w:val="MMMM d, yyyy"

officecli get "$FILE" '/body/sdt[N]'   # expect: type=date format=yyyy年MM月dd日

setattr replaces one attribute — do not quote the value inside --xml. Only w:val is touched; the <w:dateFormat> wrapper is preserved.

raw-set actions & errors

Path C — Word template workflow

For fields CLI cannot express (signature picture SDT, real SDT checkbox, placeholderDocPart prompt text, grouped SDTs, custom richtext styling), build the skeleton once in Word, then fill via CLI.

One-time in Word: File → Options → Customise Ribbon → Developer. Developer tab → Insert Picture / Check Box / Grouping Content Control → right-click → Properties → set Title (alias) + Tag. Save as template.docx.

Fill via CLI:

cp templates/onboarding_with_signature.docx "$FILE"
officecli open "$FILE"
officecli view "$FILE" forms                                    # see /body/... paths + sdtId values
officecli set "$FILE" '/body/sdt[@sdtId=3]' --prop text="Jane Smith"
officecli set "$FILE" / --prop protection=forms
officecli close "$FILE"

MERGEFIELD (data-driven track)

help docx field declares a fieldType enum of ~30 values including mergefield, ref, pageref, seq, if — all CLI-expressible with their typed props. MERGEFIELD coexists with SDT in the same file but is reported by query field only; view forms does NOT list MERGEFIELDs (they are not user-fillable).

Canonical MERGEFIELD:

officecli add "$FILE" /body --type paragraph --prop text="Dear "
officecli add "$FILE" '/body/p[1]' --type field --prop fieldType=mergefield --prop name=CustomerName
officecli add "$FILE" '/body/p[1]' --type run --prop text=", "
officecli add "$FILE" '/body/p[1]' --type field --prop fieldType=mergefield --prop name=CompanyName
# Readback: "Dear «CustomerName», «CompanyName»"

Element-type shortcut (equivalent): officecli add "$FILE" '/body/p[1]' --type mergefield --prop name=CustomerName.

Common field patterns

IF conditional (CLI-expressible)

officecli add "$FILE" /body --type paragraph --prop text=""
officecli add "$FILE" '/body/p[last()]' --type field --prop fieldType=if \
  --prop expression='{ MERGEFIELD Gender } = "Male"' \
  --prop trueText="Mr." --prop falseText="Ms."
officecli add "$FILE" '/body/p[last()]' --type run --prop text=" "
officecli add "$FILE" '/body/p[last()]' --type field --prop fieldType=mergefield --prop name=LastName
# Merge-time result: "Mr. «LastName»" or "Ms. «LastName»"

Nested wrappers like { IF { MERGEFIELD X } = "Y" { REF bm } "fallback" } are not expressible via --prop chaining — drop to raw-set a hand-crafted <w:fldChar> / <w:instrText> fragment, or build once in a Word template (Path C).

Readback. query $FILE field lists /field[N] + instruction + fieldType. view $FILE forms does NOT list MERGEFIELDs (only SDT + formfield) — they are template-time, not end-user fillable. get $FILE '/body/p[1]' renders the guillemet-wrapped field name.

Legacy FormField

Use FormField when you need a real checkbox. For text/dropdown, prefer SDT.

help docx formfield: type (text/checkbox/check/dropdown), name (required, ≤ 20 chars — OpenXML schema MaxLength; add passes longer but validate rejects), text (text only, alias value), checked (checkbox only).

# CHECKBOX — the only real checkbox (SDT type=checkbox is not implemented)
officecli add "$FILE" /body --type formfield --prop type=checkbox \
  --prop name=agree_terms --prop checked=false

# TEXT formfield
officecli add "$FILE" /body --type formfield --prop type=text \
  --prop name=emp_name --prop text="Enter name"

# DROPDOWN formfield — items NOT settable via CLI; use Word template or SDT Path B
officecli add "$FILE" /body --type formfield --prop type=dropdown --prop name=dept_select

# Read / modify by name (stable) or 1-based index
officecli get "$FILE" '/formfield[agree_terms]'
officecli set "$FILE" '/formfield[agree_terms]' --prop checked=true
officecli set "$FILE" '/formfield[emp_name]' --prop text="Jane Smith"
officecli set "$FILE" '/formfield[dept_select]' --prop text="Engineering"

FormField paths (/formfield[N] or /formfield[<name>]) are separate from SDT paths (/body/sdt[N]). Both coexist; protection=forms covers both.

Scale. Tested with 50+ checkboxes in a single document — no practical cap on formfield count; build and validate remain clean. name ≤ 20 chars (K13) is the only hard constraint.

Renderer note — formfield checkbox [RENDERER-BUG]. LibreOffice's PDF export occasionally renders the formfield checkbox as ☐☐ (doubled box). Word and WPS render a single clickable box (toggles ☑). This is a LibreOffice renderer quirk, not a skill or document quality issue — see K19. Do not attempt workarounds in the form; if an evaluator screenshots a LibreOffice-generated PDF and sees `☐
