  • Calls curl; reaches jstodocx.com; needs JSTODOCX_API_KEY

What it does

Jstodocx API is an agent skill from aiskillstore/marketplace. Generate Microsoft Word DOCX files through the jstodocx.com API. Use when Codex needs to create or download .docx files from basic HTML, JavaScript source text, or controlled document template fields; when a user asks for HTML to DOCX, JS source to Word, or template-based DOCX generation via an API; or when integrating a lightweight Cloudflare Worker DOCX conversion endpoint into scripts, tests, or agent workflows.

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/api.md` and `skill-report.json`).

It sits in Documents & Office, covering Word documents. It works with Microsoft Word, JavaScript, python-docx and Cloudflare Workers. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Codex needs to create
  • Download .docx files from basic HTML
  • JavaScript source text
  • Controlled document template fields

Example prompts

  • “/jstodocx-api”

Requirements

  • A credential in JSTODOCX_API_KEY

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Choose one mode
  2. Send POST https://jstodocx.com/api/v1/docx with content-type: application/json.
  3. If the endpoint returns 401, ask the user for an API key or use the browser-local website instead. Do not guess credentials.
  4. Save the binary response to a .docx file.
  5. Verify the result when possible by checking the response content-type, filename, and ZIP magic bytes PK.

What it can do on your machine

Read from SKILL.md and the folder at commit 755bc35. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • jstodocx.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • JSTODOCX_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Jstodocx API loads about 683 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 236 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~683
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 236 words (~683 tokens).

“Use the jstodocx.com API to create Word .docx files from controlled inputs. The API is useful for agents that need a downloadable DOCX without installing document-generation dependencies locally.”
