Project install by default; add -g for ~/.claude/skills/.

GitHub CLI

$ gh skill install spiriMirror/libuipc document --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

What it does

Document is an agent skill from spiriMirror/libuipc. Documentation style guide and rules for creating documentation

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content. The repository describes itself as: A Modern Python and C++20 Library of Unified Incremental Potential Contact. The licence is Apache-2.0.

When your agent uses it

Writing & Content work in your project

Example prompts

“/document”

Requirements

Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 9c748a7. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
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:
- cmake.org
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Document loads about 930 tokens when it runs. Until then it costs about 18 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~18
When it runs · the whole SKILL.md, loaded when a task matches: ~930

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.

description: Documentation style guide and rules for creating documentation

Document Rules

Documentation style varies by type. Follow these principles for consistency.

Specification Documents (`docs/specification/`)

Purpose: Formal mathematical reference for constitutions, geometries, and core concepts.

Rules:

Use LaTeX math ($$ for display, $ for inline) extensively
Define all variables after formulas
Prefer math over code examples
Structure: Definition → State Variables → Formulations → Energy Functions
Use numbered sections: ## #12 Hookean Spring
Reference academic papers when applicable
Include parameter ranges: "$100MPa \le \kappa \le 100GPa$"
Explain notation: "where $|\cdot|_F$ is the Frobenius norm"
Cross-reference: [link text](./file.md)
Include diagrams (SVG): ![Description](./media/figure.svg)

Example:

markdown

# Hookean Spring

**Hookean Spring** is a constitutive model for simulating linear elastic springs.

## #12 Hookean Spring

$$
E = \frac{\kappa}{2} \epsilon^2 = \frac{\kappa}{2} \left(\frac{L - L_0}{L_0}\right)^2
$$

where:
- $\kappa$ is the spring constant
- $L_0$ is the rest length

Tutorial Documents (`docs/tutorial/`)

Purpose: User-friendly guides with code examples.

Rules:

Always provide both C++ and Python using tabs:

markdown

=== "C++"
    \`\`\`cpp
    // code
    \`\`\`
=== "Python"
    \`\`\`python
    # code
    \`\`\`

Include complete, runnable examples with imports
Start high-level, progress to details
Use diagrams: ![description](./media/file.svg)
Include step-by-step workflows
Use tables for structured data

Example:

markdown

=== "C++"
    \`\`\`cpp
    using namespace uipc::core;
    Scene scene;
    \`\`\`
=== "Python"
    \`\`\`python
    from uipc.core import *
    scene = Scene()
    \`\`\`

Reference Documents (`docs/specification/*_uid.md`)

Purpose: Technical reference for identifiers and ranges.

Rules:

Define identifier ranges clearly
Distinguish official vs. user-defined ranges
List all official identifiers
Cross-reference to detailed specs

Example:

markdown

# Constitution UID

64-bit unsigned integer. Official range: $[0, 2^{32}-1]$. User-defined: $[2^{32}, 2^{64}-1]$.

Build/Install Documents (`docs/build_install/`)

Purpose: Step-by-step build instructions.

Rules:

Use prerequisites table with versions and links
Number steps clearly
Include verification commands
Use shell tags: shell, bash, powershell
Show copy-pasteable commands

Example:

markdown

| Name | Version | Usage | Import |
|------|---------|-------|--------|
| [CMake](https://cmake.org/) | >=3.26 | build system | system install |

\`\`\`shell
git clone https://github.com/microsoft/vcpkg.git
\`\`\`

General Rules

Math: $$ for display, $ for inline. Define variables after formulas. Use bold for vectors: $\mathbf{x}$
Code: Appropriate language tags. Complete, runnable examples. C++/Python tabs in tutorials
Links: Relative paths [text](./file.md). Link to related docs and external resources
Media: Store in media/ subdirectories. Use SVG. Reference: ![Description](./media/file.svg)
Tables: Markdown tables with headers for structured data
Headers: # title, ## sections, ### subsections

Checklist

Formulas use LaTeX, variables defined
Code examples complete and runnable
Cross-references use relative paths
Images exist and are referenced
Tables formatted correctly
Document type principles followed
No ambiguity in technical descriptions

Questions about Document

What does Document do?

Documentation style guide and rules for creating documentation. Document is an agent skill from spiriMirror/libuipc.

When should I use Document?

Document fits situations like: writing & Content work in your project.

How do I install Document in Claude Code?

Run `npx skills add spiriMirror/libuipc --skill document -a claude-code`. Or copy the skill folder (.cursor/skills/document in spiriMirror/libuipc) into .claude/skills/document in your project. Claude Code loads it when a task matches its description.

How do I install Document in Codex?

Run `npx skills add spiriMirror/libuipc --skill document -a codex`. Or copy the skill folder (.cursor/skills/document in spiriMirror/libuipc) into .agents/skills/document in your project. Codex loads it when a task matches its description.

Can I use Document in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add spiriMirror/libuipc --skill document -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/document, .gemini/skills/document, .github/skills/document and .opencode/skills/document in your project.

What does Document need to run?

SKILL.md names no scripts, command-line tools or credentials: Document is instructions for the agent only. Our summary lists: Python 3.

Does Document access the network?

SKILL.md names 2 domains. In commands or code: cmake.org and github.com; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.

Is Document safe to install?

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.

What licence does Document use?

Document 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.

How many tokens does Document use?

About 930 tokens (SKILL.md is roughly 3.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Document?

Skills that share tags, products or a category with Document: Humanizer (Azure-Samples/interview-coach-agent-framework, 172 stars), Avoid AI Writing (conorbronsdon/avoid-ai-writing, 4.9k stars), JavaScript Concept Fact Checker (leonardomso/33-js-concepts, 67k stars) and User-Facing Text Cleanup (guillaumemeyer/watermarks-remover, 23k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Document?

spiriMirror (a GitHub organization) maintains it in spiriMirror/libuipc, which has 335 GitHub stars. The repository holds 16 skills in this directory. The repository was last updated on October 3, 2026.
