Flipbook Docs and Writing
This skill covers the Flipbook documentation estate, publication workflow, house style and conventions, and templates for creating new docs pages and skills. Use this when maintaining the site, writing new docs, enforcing prose rules, or helping new contributors author documentation.
Documentation Estate Map
The Flipbook docs have three layers, each with distinct purpose and audience:
Layer 1: Docusaurus Site (User-Facing)
Location: docs/ directory at repo root.
Build system: Docusaurus 3.6.1 (verified 2026-07-01 in docs/package.json). Config in docs/docusaurus.config.ts, sidebars in docs/sidebars.ts.
Deployment: docs.yml workflow builds on PR and release; deploys to flipbook-labs.github.io/flipbook on release or manual dispatch. Build runs npm ci + npm run build in docs/ directory.
Content root: docs/docs/ with sections:
intro.md — product intro and features.install.md — setup instructions.creating-stories/ — user guide: writing stories, controls, typechecking, story format (MDX with embedded code samples).frameworks/ — per-framework integration (React, Roact, Fusion, etc., auto-discovered).contributing/ — contributor onboarding and release workflow (auto-discovered).migration-guides/ — for users migrating from UI Labs, Hoarcekat, etc.
Code samples: Live in workspace/code-samples/ and are embedded in docs via raw-loader Webpack imports or Docusaurus remark plugin. Samples are real, working code; if source changes, docs automatically reflect it. Never hardcode examples — pull them live.
Verification command: lute run serve-docs (verified in .lute/serve-docs.luau) runs npm install + npm start in docs/ to start local dev server; browser opens automatically.
Layer 2: Obsidian Vault (Institutional Knowledge — Pending Merge)
Status: Branch flipbook-docs (unmerged as of 2026-07-01) contains comprehensive Obsidian vault at docs/obsidian-vault/ with 8,500+ lines across engineering, product, usage, and concepts.
Staleness check: Branch is current (merged main 2026-06-28, 3 days old); no conflicting API changes; vault is production-ready for publication.
Structure (from the vault on the flipbook-docs branch, as of 2026-07-01 — browse with git ls-tree -r --name-only flipbook-docs -- docs/obsidian-vault):
engineering/ — architecture decisions, build pipeline, module loader design, story controls revamp, changewrite workflow, telemetry strategy.product/ — roadmap, northstars, product vision, UX ideas.usage/ — user guides complementing public docs (story format, controls, component library).concepts/ — story, storybook, module-loader, and renderer concepts (bridge between user and engineer).contributing/ — maintainer onboarding, testing architecture, CI flow.drafts/ — pending work (docs overhaul plan, research notes, stale proposals).
Publication pathway: Vault is build-excluded from public site now; remark plugin docs/site/src/remark/obsidian.mjs and sidebar builder docs/site/src/sidebar/obsidian.mjs are configured to ingest it. To publish: merge flipbook-docs to main, run lute run serve-docs, deploy via docs.yml.
Pre-merge checklist (from docs overhaul plan):
- W1: Strip notion-id + linter-yaml-title-alias metadata; keep aliases only when distinct from H1.
- W2: Fix engineering MOC (delete tech-1.md stub, rebuild engineering/index.md).
- W3: Convert Obsidian Bases to static Markdown tables.
- W4: Normalize index notes to intro + blurbed-bullet-list format.
- Validate all wikilinks resolve; check code sample paths in workspace/code-samples/.
Layer 3: Agent Skills and Runbooks
Location: .agents/skills/ — canonical, vendor-neutral home for agent-facing procedures, maintainer playbooks, and reference. Routed via the Project Skills index in AGENTS.md; conventions in .agents/skills/README.md.
Audience: Sonnet-class model, zero-context mid-level engineer.
Each skill has: frontmatter (name, description, type: process | knowledge), when-not-to-use section, provenance/verification commands, date-stamped volatile facts. New/renamed skills must update the AGENTS.md index in the same commit.
One home per fact: Docs layer owns user-facing knowledge; skills layer owns agent/maintainer procedures. Cross-reference by repo-relative path instead of restating (e.g., "For user story format, see docs/docs/creating-stories/story-format.mdx").
House Style and Conventions
Prose Rules
Unwrapped lines: Each paragraph or bullet list is one long line. No hard line breaks mid-sentence. Prettier enforces this for markdown.
Avoid rule-of-three: Don't use rhetorical tricolon constructions ("A, B, and C") for emphasis. List items or numbered steps are fine; rhetorical emphasis via three-item parallelism is discouraged.
Jargon on first use: Define every term on first mention. Example: "Darklua is a Luau-to-Roblox-require transpiler that rewrites string imports (@pkg/Charm) to property-access requires during build."
Comments describe the present: In source code, comments explain why the code is written this way now — for a reader who has never seen a prior version. Never write comments that narrate a refactor (e.g., "This used to be inline" or "Where did all the logic go? It moved to X"). See AGENTS.md for full doctrine.
Markdown Formatting
Tool: Prettier (verified in lute run lint which runs npx prettier --check "**/*.md" and can auto-fix via npx --yes prettier --write "**/*.md").
Frontmatter: Docusaurus pages use YAML frontmatter. Minimal example:
---
sidebar_position: 1
---
Standard keys: sidebar_position (sort order in category), id (for stable URLs), title (defaults to H1; rarely needed). Obsidian vault also uses aliases (alternate names, only when distinct from H1).
One H1 per page. Never use multiple top-level headings.
Code blocks: Use Docusaurus CodeBlock component for embedded examples (MDX), or ```lua fenced blocks in markdown. For Obsidian, use ```code-sample fenced blocks with workspace-relative paths (e.g., ```code-sample workspace/code-samples/src/React/ReactButton.luau#L4-L13 `).
Tables: Use Markdown pipe tables; static, never Obsidian Bases. Example:
| Control Type | Supported | Notes |
|---|---|---|
| Boolean | Yes | — |
| Color | Yes | Requires Color3 |
See also blocks: Use > [!seealso] callout blocks (Obsidian standard) at the bottom of pages to link related docs.
Wikilinks: Obsidian vault uses [[path/to/page]]; public site uses standard Markdown [link text](/docs/path/to/page).
Pull Request Descriptions
A PR body exists to orient the human who has to review an ever-growing diff. Its job is to inform and orient — explain what the change does and why it exists — not to catalog every line. The file-change view already owns the granular detail; the body should let a reviewer feel informed before they open a single file. This covers how to write the body; for the surrounding workflow (version gating, CI gates, review discipline) see flipbook-change-control.
Follow the repo template. .github/pull_request_template.md defines the sections: Problem (why the change is needed), Solution (what it does and any non-obvious decisions), Testing (how it was verified), and Notes for reviewers (tradeoffs, risks, follow-ups). Fill each in; don't invent a custom structure.
Lead with prose, keep code sparse. Name things in sentences rather than wrapping every identifier in backticks — a body where half the nouns are inline code is unscannable, and the reader's eye snags on each one. Reserve inline code for things that genuinely read as code: a file path, an alias, a command, a version string. If a paragraph carries more backticks than commas, rewrite it as prose plus a table.
Push granular detail into tables and lists. A "what changed" table grouped by area (not one row per file) and a verification table mapping each check to its result carry dense facts far better than a paragraph studded with identifiers. Group and summarize; the reviewer drops into the diff when they want the per-file specifics.
Keep the altitude high. Explain intent and the decisions a reviewer couldn't infer from the diff; let the mechanical parts speak for themselves. A reader should finish the body knowing why the PR exists, what it changes at a high level, and what to watch for — then reach for the files for anything finer.
For a worked example of this style on a dependency-bump PR, see #608.
Local Workflow
Running Docs Locally
Command: lute run serve-docs (verified .lute/serve-docs.luau).
This command:
- Runs
npm install in docs/ to fetch Docusaurus and plugins.
- Runs
npm start to start dev server.
- Opens browser automatically to
http://localhost:3000/flipbook/.
Auto-reloads on markdown edits. Press Ctrl+C to stop.
Linting and Formatting
All together: lute run lint (verified in AGENTS.md, runs Selene + StyLua + Prettier).
Markdown only: npx --yes prettier --write "**/*.md" (fixes line wrapping and formatting).
Type check: lute run analyze (checks Luau; not directly docs-related but affects code samples).
Templates
New Docusaurus Page Template
Create a new .mdx file under docs/docs/ with this skeleton:
---
sidebar_position: 1
---
# Page Title
One-sentence intro describing what the reader will learn.
## Section 1
Paragraph with inline `code`, links to other docs (`[link text](/docs/path)`), and
bullet lists when helpful.
- First item
- Second item
- Third item
## Section 2
Docusaurus supports MDX, so you can embed React components. For code samples, use
the CodeBlock component:
```lua
-- Example code from workspace/code-samples
Subsection
Use :::tip, :::warning, :::info, :::danger for callout boxes.
:::tip
This is a helpful tip for users.
:::
:::warning
This is something to be careful about.
:::

**Frontmatter notes:**
- `sidebar_position` determines sort order within the category (lower numbers come first).
- Omit `title` unless it differs from the H1.
- Most pages don't need `id` (Docusaurus infers it from filename).
### New Skill Template
Create a new SKILL.md under `.agents/skills/<skill-name>/` with this skeleton:
```markdown
---
name: skill-name
description: "Brief trigger-rich description stating exactly when this skill should load. Use when: [specific cases]. Covers: [main topics]."
type: process | knowledge (pick one; see .agents/skills/README.md for the filing rule)
---
# Skill Title
One-sentence statement of what this skill does and who uses it.
## When not to use
Link to related skills in the library that handle adjacent work. Example: "For telemetry implementation, see flipbook-config-and-flags. For release automation, see flipbook-release-and-operations."
## Section 1: Major Topic
Body content with clear examples, copy-pasteable commands, and explanations.
**Verified command:** (command that can be run to validate a claim)
```bash
lute run build --channel dev
Unverified note: (if you cannot verify a claim, label it explicitly)
This feature is marked as "not yet started" in the 2026 roadmap.
Section 2: Another Topic
More structured content with tables, checklists, or runbooks where they help.
Provenance and Maintenance
Date stamped: as of 2026-07-01.
Re-verify these claims when this skill next loads:
lute run serve-docs behavior: run and confirm dev server starts- Docusaurus config: check
docs/docusaurus.config.ts for layout changes
- Branch status: confirm
flipbook-docs has not been merged or archived
**Frontmatter rules:**
- `name`: slug (kebab-case, matches directory name).
- `description`: trigger-rich, states exactly when to load; use "Use when:" followed by specific scenarios.
- `type`: `process` (runbook — what to do next) or `knowledge` (reference — how the system is and why); filing rule in `.agents/skills/README.md`.
**Structure:**
1. Title and one-sentence summary.
2. "When not to use" section linking siblings.
3. Main body (numbered sections, tables, checklists).
4. "Provenance and Maintenance" footer with date stamp and re-verification commands.
**Audience:** Imperative runbook voice; copy-pasteable commands; every tool/flag/path verified before stating.
## Code Sample Extraction System
**How it works:** Docs reference real Luau from `workspace/code-samples/` using Docusaurus remark plugin and Obsidian plugin.
**Syntax (Obsidian vault):**
workspace/code-samples/src/React/ReactButton.luau#L4-L13
**Syntax (Docusaurus MDX):**
```mdx
import ReactButton from "!!raw-loader!@site/../workspace/code-samples/src/React/ReactButton.luau";
<CodeBlock language="lua" title="ReactButton.luau">
{ReactButton}
</CodeBlock>
Benefits:
- Examples never drift from source.
- If code changes, docs automatically reflect it.
- Single source of truth for all sample code.
Workflow: Add sample code to workspace/code-samples/ directory, then reference it from docs.

Common Patterns
Linking Between Pages
Docusaurus (user-facing): Use root-relative paths with /docs/ prefix:
See [Writing Stories](/docs/creating-stories/writing-stories) for the full guide.
Obsidian (vault): Use wikilinks:
See [[creating-stories/writing-stories]] for the full guide.
Embedding Code Samples
When the sample is short (< 10 lines): Inline the code in a fenced block.
When the sample is long or lives in the repo: Reference via code-sample or raw-loader so it auto-updates if source changes.
Callout Boxes
Docusaurus and Obsidian both support callout syntax:
:::tip
Helpful information for users.
:::
:::warning
Something to be careful about.
:::
:::danger
Critical warning.
:::
:::info
General information.
:::
Or Obsidian callout syntax:
> [!tip]
> Helpful information
Sidebars and Navigation
Docusaurus sidebar structure is in docs/sidebars.ts. Add new pages by:
- Create
.mdx file under appropriate section in docs/docs/.
- Add path to sidebars config (or use
autogenerated to auto-discover).
- Set
sidebar_position in frontmatter to control sort order.
Example sidebar entry:
{
type: 'category',
label: 'Stories',
collapsed: false,
items: [
'creating-stories/writing-stories',
'creating-stories/controls',
]
}

Re-verify these claims when this skill next loads:
- Docusaurus version and config: check
docs/package.json and docs/docusaurus.config.ts for breaking changes.
- Serve-docs command: run
lute run serve-docs and confirm dev server starts and auto-reloads on markdown edits.
- Branch status: confirm
flipbook-docs branch status (merged, archived, or still pending).
- Sidebar structure: check
docs/sidebars.ts to ensure sections match current documentation tree.
- Prettier markdown enforcement: run
lute run lint to confirm markdown formatting is checked.
