technical-doc-creatorCreate HTML technical documentation with code blocks, API workflows, system architecture diagrams, and syntax highlighting.
Technical Doc Creator is an agent skill from mhattingpete/claude-skills-marketplace. Create HTML technical documentation with code blocks, API workflows, system architecture diagrams, and syntax highlighting. Use when users request technical documentation, API docs, API references, code examples, or developer documentation.
Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `references/design_patterns.md` and `references/svg_library.md`).
It sits in Development, covering Technical documentation and Diagrams. The repository describes itself as: Claude Code Skills for software engineering workflows - Git automation, testing, and code review. The licence is Apache-2.0.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit b5b34bc. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are html).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Technical Doc Creator loads about 604 tokens when it runs, and up to ~7.7k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 127 words of instructions outside code blocks.
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.
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.

Technical Doc Creator fits situations like: users request technical documentation; developer documentation.
Run `npx skills add mhattingpete/claude-skills-marketplace --skill technical-doc-creator -a claude-code`. Or copy the skill folder (visual-documentation-plugin/skills/technical-doc-creator in mhattingpete/claude-skills-marketplace) into .claude/skills/technical-doc-creator in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mhattingpete/claude-skills-marketplace --skill technical-doc-creator -a codex`. Or copy the skill folder (visual-documentation-plugin/skills/technical-doc-creator in mhattingpete/claude-skills-marketplace) into .agents/skills/technical-doc-creator in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mhattingpete/claude-skills-marketplace --skill technical-doc-creator -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/technical-doc-creator, .gemini/skills/technical-doc-creator, .github/skills/technical-doc-creator and .opencode/skills/technical-doc-creator in your project.
SKILL.md names no scripts, command-line tools or credentials: Technical Doc Creator is instructions for the agent only. Our summary lists: Node.js.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Technical Doc Creator is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 604 tokens (SKILL.md is roughly 2.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 7.1k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Technical Doc Creator: Diagram Design (cathrynlavery/diagram-design, 47k stars), Draw.io Diagram Studio (Agents365-ai/drawio-skill, 10k stars), Dark Architecture Diagram Builder (Cocoon-AI/architecture-diagram-generator, 7.4k stars) and Pretty Mermaid Renderer (imxv/Pretty-mermaid-skills, 1.5k stars).
