multik-docs: Скилл для работы с документацией

--- name: multik-docs description: "Write and edit Writerside user documentation pages for the Multik library. Covers all page types: Getting Started, User Guide, and API Reference. Handles page structure, Korro code samples, mk.tree navigation, and cross-references. Use this skill when creating new doc pages, updating existing ones, or when the multik-kdoc skill needs to create/update Writerside topics." --- # Multik User Documentation Write and edit Writerside documentation for the Multik library. Documentation lives in `docs/topics/` and is organized into three categories, each with distinct structure and purpose. ## Documentation Philosophy Before writing, internalize these principles: **From the Diataxis framework** (full reference: `references/diataxis-framework.md`): - Tutorials teach beginners through step-by-step instructions with concrete results - Guides solve specific problems for intermediate users - Reference docs provide precise technical information for lookup - Explanations build deeper understanding for experts **Project doc rules** (full reference: `references/doc-quality-rules.md`): - Be concise — make every token count - Optimize for skimming: bold, lists, headings, code examples - Keep the first-time experience simple, reveal complexity gradually - Ensure docs have many code examples users can copy/paste or run - Cross-link related guides, APIs, and examples - Make content easy for AI to consume as Markdown ## Page Types ### API Reference (`docs/topics/apiDocs/`) — strict templates **Audience:** Experienced users. **Purpose:** Precise technical lookup. API reference pages must look uniform. Three sub-types: - **Single function pages** — one function (possibly overloaded) per page: Signature → Parameters → Returns → Example → optional Pitfalls - **Multi-function pages** — for closely related functions on one page (e.g., `descriptive-statistics.md`): each function gets its own H2 with nested H3 sub-sections and anchor IDs - **Index pages** — group related function pages into navigable tables (e.g., `array-creation.md`, `statistics.md`) Read `references/api-reference-templates.md` for exact structural templates with real examples. ### Free-form pages — no rigid template These pages vary in structure depending on the topic. Instead of following a template, **read 2-3 existing pages of the same type** before writing to match the tone and patterns. **Getting Started** (`docs/topics/gettingStarted/`): Narrative style for beginners. Onboarding, installation, platform setup. May use tabs for Gradle Kotlin/Groovy, bullet lists, multiple Korro imports. Examples: `quickstart.md`, `installation.md`, `engines-of-multik.md`. **User Guide** (`docs/topics/userGuide/`): Task-oriented for intermediate users. Typically opens with `## Overview`, each section is self-contained (brief prose + code example). Examples: `copies-and-views.md`, `indexing-and-slicing.md`, `creating-multidimensional-arrays.md`. **FAQ** (`docs/topics/FAQ.md`): H2 headings for topic groups, H3 headings as questions. Direct answers with code examples, uses **Fix:** and **Workaround:** labels. **Community & Contribution** (`docs/topics/community-and-contribution.md`): Freeform informational page with links, lists, tables. **Landing pages** (`.topic` XML files): Pure XML format for section entry points (e.g., `welcome.topic`, `getting-started.topic`). See `references/writerside-markup.md` for the XML schema. ## Workflow ### Creating a New Page 1. **Determine the page type** based on audience and purpose (see above). 2. **For API Reference:** read `references/api-reference-templates.md` and follow the exact template for the sub-type (only load this file for API Reference pages). **For other pages:** read 2-3 existing pages of the same type to match tone and structure. Look at nearby pages in `mk.tree` for context. 3. **Read source code** — understand the API you're documenting. Check KDoc for descriptions, parameters, edge cases. 4. **Write the page** — API Reference uses strict templates; other pages adapt to their content while following the common elements below. 5. **Create Korro samples** if the page needs executable code examples (see Korro section below). 6. **Update `docs/mk.tree`** to add the page to the navigation (see mk.tree section below). 7. **Add cross-references** — link from existing related pages to the new one, and from the new page to related ones via `<seealso>` and inline links. ### Editing an Existing Page 1. **Read the current page** and understand its structure and content. 2. **Read the source code** for the API being documented to check accuracy. 3. **Make targeted changes** — don't restructure the whole page unless asked. 4. **Update Korro samples** if code examples changed (both the markdown block and the test file). 5. **Check cross-references** — update any pages that link to changed sections. ## Common Page Elements Every markdown page uses these elements in this exact order at the top: ```markdown # Page Title <!---IMPORT samples.docs.category.ClassName--> <web-summary> Two to three sentences for search results and SEO. </web-summary> <card-summary> One to two sentences for card previews. </card-summary> <link-summary> One sentence for inline link hover previews. </link-summary> ``` - `# Title` is always the first line (H1). Exactly one per page. - `<!---IMPORT ...-->` appears only when the page uses Korro samples. Multiple imports are allowed. - The three summary blocks are required on every page, always in web → card → link order. - `web-summary` is the longest, `link-summary` is the shortest. ### Seealso Block Every page ends with a `<seealso>` block for related content: ```xml <seealso style="cards"> <category ref="api-docs"> <a href="page-name.md" summary="Brief description of the linked page."/> </category> </seealso> ``` Or with a title and multiple categories: ```xml <seealso style="cards" title="Next steps"> <category ref="user-guide"> <a href="page.md" summary="Description."/> </category> <category ref="api-docs"> <a href="page.md" summary="Description.">Custom Link Title</a> </category> </seealso> ``` Category refs: `"user-guide"`, `"api-docs"`, `"get-start"`, `"ext"` (external links). ### Cross-References Three patterns, in order of preference: 1. **Auto-titled link:** `[](page-name.md)` — resolves to the page title. Best for inline references. 2. **Custom text link:** `[link text](page-name.md)` — for when the page title doesn't fit the context. 3. **Deep link with anchor:** `[text](page-name.md#anchor-id)` — for linking to specific sections. ### Admonitions ```markdown > Warning text here. > {style="warning"} > Note text here. > {style="note"} > Tip text here. > {style="tip"} ``` When using non-standard Writerside elements (tabs, compare blocks, procedures, topic switchers, etc.), read `references/writerside-markup.md` for syntax reference. Skip this file for pages that only use standard markdown, code blocks, admonitions, and seealso blocks. ## Korro Code Samples Korro is a Gradle plugin that synchronizes code snippets between Writerside markdown and executable Kotlin test files. This ensures documentation examples always compile and produce expected output. ### How It Works **Markdown side** (`docs/topics/{category}/page.md`): ```markdown <!---IMPORT samples.docs.apiDocs.ArrayCreation--> <!---FUN arange_example--> ```kotlin val a = mk.arange<Int>(5) // [0, 1, 2, 3, 4] val b = mk.arange<Int>(2, 10, 3) // [2, 5, 8] ``` <!---END--> ``` **Kotlin side** (`multik-core/src/commonTest/kotlin/samples/docs/{category}/ClassName.kt`): ```kotlin package samples.docs.apiDocs import org.jetbrains.kotlinx.multik.api.* import kotlin.test.Test class ArrayCreation { @Test fun arange_example() { // SampleStart val a = mk.arange<Int>(5) // [0, 1, 2, 3, 4] val b = mk.arange<Int>(2, 10, 3) // [2, 5, 8] // SampleEnd } } ``` ### Key Rules - `<!---FUN name-->` must match the `@Test fun name()` method name exactly - `<!---IMPORT package.ClassName-->` must match the test class fully-qualified name - Code between `// SampleStart` and `// SampleEnd` is what appears in the markdown code block - Assertions (`assertEquals(...)`) go after `// SampleEnd` — they validate but don't appear in docs - Output is shown as comments: single-line with `//`, multi-line with `/* ... */` - Sample files are organized by category: - `samples/docs/apiDocs/` for API Reference pages - `samples/docs/userGuide/` for User Guide pages - `samples/docs/` root for Getting Started and other pages ### Creating a New Sample 1. Check if an existing sample class covers the topic. If so, add a new `@Test fun` method to it. 2. If not, create a new class. Name it in PascalCase matching the topic (e.g., `ShapeManipulation.kt` for `shape-manipulation.md`). 3. Package must match the directory: `samples.docs.apiDocs` or `samples.docs.userGuide`. 4. Add the `<!---IMPORT ...-->` directive at the top of the markdown page. 5. Wrap each code example in `<!---FUN name-->` / `<!---END-->` blocks in the markdown. ### Validation After creating or updating samples, remind the user to run: ```bash ./gradlew :multik-core:jvmTest --tests "samples.docs.*" ``` ## Updating mk.tree The navigation tree is defined in `docs/mk.tree`. When adding a new page: 1. Find the correct parent `<toc-element>` for the page type: - Getting Started: inside `<toc-element toc-title="Getting started" topic="getting-started.topic">` - User Guide: inside `<toc-element topic="user-guide.topic">` - API Reference: inside `<toc-element toc-title="API reference">` 2. Add a `<toc-element topic="your-page.md"/>` at the appropriate position. 3. For sub-pages, nest inside the parent `<toc-element>`. 4. Use `toc-title="Custom Title"` only when the page's H1 isn't suitable for the sidebar. 5. Use `wip="true"` for pages that are not yet complete. Example: ```xml <toc-element topic="array-creation.md"> <toc-element topic="arange.md"/> <toc-element topic="your-new-function.md"/> <!-- ... --> </toc-element> ``` ## Writing Quality Checklist Before finishing any page: - [ ] H1 title is present and descriptive - [ ] All three summary blocks are present (web, card, link) - [ ] Code examples compile and show expected output - [ ] Korro directives match the sample test files (`<!---IMPORT-->` and `<!---FUN-->`) - [ ] Cross-references use correct page filenames - [ ] `<seealso>` block at the end with 2-4 relevant links - [ ] Page added to `mk.tree` in the correct location (for new pages) - [ ] Tone matches the page type (tutorial vs reference vs guide) - [ ] No jargon or idioms without explanation - [ ] Optimized for skimming — short paragraphs, bold key terms, lists, headings
