What is docx-generator?

A document generator that creates Microsoft Word DOCX files from Markdown or structured data. DOCX is the file format used by Microsoft Word, and OOXML is the internal document standard it must follow.

Use it to produce Word documents from Markdown or a structured document tree, with a specified output path when needed.

It turns text or structured content into a Word file while following the required file format rules. This avoids relying on a manually assembled or invalid DOCX package.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 38 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 10,943 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.10943
Opus 5.5	$0.00015	$0.04377
Sonnet 5.5	$0.00008	$0.02189
Haiku 4.5	$0.00004	$0.01094

Security

Grade A, and why

docx-generator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 553 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CODE SKILL — VERBATIM REQUIRED This skill targets a formal specification (OOXML). Adaptation is prohibited per C2-A Rule 3.

CRITICAL: Execution Constraints

The code below is the SOLE IMPLEMENTATION — it MUST NOT be replaced, simplified, or reimplemented.

Prohibited deviations:

Do NOT write your own crc32() — use ONLY the one in Runnable Entry Point
Do NOT write your own ZipStream class — use ONLY the one in Runnable Entry Point
Do NOT skip any OOXML file from the 10-file baseline
Do NOT use compression (method 8 / DEFLATE) — STORE mode only
Do NOT assemble document body XML manually outside markdownToDocxBody() or astToDocxBody()

Correct Invocation Pattern

Copy the complete script from ## Runnable Entry Point below
Replace ONLY {{input}}, {{output}}, {{mode}} with actual values
Execute as a single jsexec call with NO modifications

Argument Details

Arg	Type	Required	Default	Description
`input`	`string`	yes	—	Markdown string or structured AST
`output`	`string`	no	`/generated_document.docx`	Output .docx file path
`mode`	`string`	no	`markdown`	Input mode: `markdown`
