What it does

Eisland Dev Update Docs is an agent skill from JNTMTMTM/eIsland. Update or create documentation in the eIsland VuePress docs site (web/eisland-web-docs). Use this skill whenever the user asks to update docs, add documentation, write a doc article, document a feature, update the tech stack docs, update plugin docs, update command docs, or any task involving files under web/eisland-web-docs/src/. This skill ensures all documentation follows the project's AGENTS.md constraints, uses correct admonition syntax, maintains consistent style with existing articles, and properly updates…

Its SKILL.md is about 1.4k 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 Agent Workflows, covering Static sites and blogs, Technical documentation and Agent instruction files. The repository describes itself as: eIsland - A sleek, Apple Dynamic Island inspired floating widget for Windows, built with Electron. The licence is GPL-3.0.

When your agent uses it

  • The user asks to update docs
  • Add documentation
  • Write a doc article
  • Document a feature

Example prompts

  • “/eisland-dev-update-docs”

Workflow steps

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

  1. Language: All documentation content must be written in English. No Chinese text allowed.
  2. Admonitions: Every documentation file MUST use admonition syntax. Each file should include at least one admonition block (:::tip, :::info…
  3. Sidebar: Do NOT register README.md files in the sidebar. VuePress automatically uses each subdirectory's README.md as the category index…
  4. Frontmatter: Every doc file must have YAML frontmatter with title and icon fields.
  5. Test Statistics: When documenting test coverage, use accurate numbers from the latest test run: 125 test files, 2068 tests. Update these…

What it can do on your machine

Read from SKILL.md and the folder at commit 411adb9. 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

    No URLs in SKILL.md.

    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

Eisland Dev Update Docs loads about 1.4k tokens when it runs. Until then it costs about 144 tokens; SKILL.md has 391 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~144
When it runs · the whole SKILL.md, loaded when a task matches
~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.

description
Update or create documentation in the eIsland VuePress docs site (web/eisland-web-docs). Use this skill whenever the user asks to update docs, add documentation, write a doc article, document a feature, update the tech stack docs, update plugin docs, update command docs, or any task involving files under web/eisland-web-docs/src/. This skill ensures all documentation follows the project's AGENTS.md constraints, uses correct admonition syntax, maintains consistent style with existing articles, and properly updates sidebar.ts and README.md indexes.

Update Docs

This skill guides documentation updates for the eIsland VuePress docs site located at web/eisland-web-docs/.

Core Rules

These rules come from the project's AGENTS.md and must be followed strictly:

  1. Language: All documentation content must be written in English. No Chinese text allowed.
  2. Admonitions: Every documentation file MUST use admonition syntax. Each file should include at least one admonition block (:::tip, :::info, :::note, :::important, :::warning, :::danger, or :::details). Use a variety of admonition types — do not rely on a single type.
  3. Sidebar: Do NOT register README.md files in the sidebar. VuePress automatically uses each subdirectory's README.md as the category index page.
  4. Frontmatter: Every doc file must have YAML frontmatter with title and icon fields.
  5. Test Statistics: When documenting test coverage, use accurate numbers from the latest test run: 125 test files, 2068 tests. Update these numbers when new test results show different counts.

Adding New Documentation

Follow these steps in order:

  1. Place the file in the appropriate subdirectory under web/eisland-web-docs/src/
  2. Add the file path to src/.vuepress/sidebar.ts under the correct group
  3. Add a link to the file in the subdirectory's README.md
  4. If creating a new subdirectory, create a README.md index for it

File Template

Every new documentation file must follow this template:

markdown
---
title: Document Title
icon: icon-name
---

# Document Title

:::info
This document covers [brief description of what this document explains]. For related information, see [Related Document](related-doc.md).
:::

## Section Heading

Content here with tables, code blocks, and admonitions.

:::tip
Helpful tips and best practices.
:::

:::warning

:::

Style Guide

Tables

Use tables for structured data — commands, configurations, comparisons, file listings:

markdown
| Command | Script | Description |
|---------|--------|-------------|
| `npm run build` | `vite build` | Build for production |
Code Blocks

Always specify the language:

markdown
```bash
npm run build
```

```typescript
const x: string = "hello";
```

```json
{ "key": "value" }
```
Show full SKILL.md (160 more words)Show less
Admonition Types

Use the right admonition for the right context:

TypeUse For
:::infoDocument introduction, general explanations
:::tipBest practices, helpful shortcuts
:::noteSupplementary information, side notes
:::importantKey information users must be aware of
:::warningCautions, potential issues, breaking changes
:::dangerCritical security notes, destructive operations
:::detailsCollapsible sections, long code references
Cross-References

Link to other documents using relative paths:

markdown
See [Frontend Setup](/developer/environment-setup/frontend-setup.md) for details.
Section Pattern for Command/Plugin Docs

For documents that describe commands or plugins, follow this pattern:

markdown
## Feature Name

**Brief description** of what this feature does.

### Build / Usage

| Command | Script | Description |
|---------|--------|-------------|
| `npm run build` | `...` | Build description |

### Test

| Command | Script | Description |
|---------|--------|-------------|
| `npm test` | `vitest run` | Run all tests |

### Source Files

| File | Responsibility |
|------|---------------|
| `src/file.ts` | What this file does |

Workflow

When updating documentation:

  1. Read the existing file (if updating) or the target directory's README.md (if creating new)
  2. Read web/eisland-web-docs/AGENTS.md for constraints
  3. Read 1-2 existing articles in the same directory for style reference
  4. Write or update the content following the style guide above
  5. Update sidebar.ts if adding a new file
  6. Update the parent README.md if adding a new file
  7. Verify all admonition blocks are properly closed
  8. Verify no Chinese text is present in the content
