Generate Docusaurus Documentation Site

Generate Docusaurus Documentation Site

Transform ADRs and OpenSpec specs (located via the Artifact Path Resolution pattern from references/shared-patterns.md) into a polished documentation website with:

• RFC 2119 keyword highlighting (MUST, SHALL, MAY, etc.)
• ADR cross-reference linking (ADR-0001 becomes a clickable link)
• SPEC cross-reference linking (PREFIX-NNN links to spec requirement anchors)
• Status/Date/Domain badge components
• Requirement box components for spec tables
• Consequence keyword highlighting (Good/Bad/Neutral) in ADRs
• Dark mode support
• Auto-generated sidebars

Supports two modes:

• Scaffold mode: Creates a standalone docs-site/ with its own Docusaurus installation
• Integration mode: Generates a build-time plugin into an existing Docusaurus site

Process

Step 0: Resolve Artifact Paths

Follow the Artifact Path Resolution pattern from references/shared-patterns.md to determine the ADR and spec directories. If $ARGUMENTS contains --module <name>, resolve paths relative to that module; otherwise, in a workspace, aggregate across all modules. The resolved ADR directory is {adr-dir} and spec directory is {spec-dir}.

Cross-module aggregation: When in aggregate mode (no --module, workspace detected), include all modules' artifacts in the docs site. Organize the sidebar navigation by module:

Architecture/
├── api/
│   ├── ADRs/
│   │   ├── ADR-0001: Choose REST over GraphQL
│   │   └── ADR-0002: Choose PostgreSQL
│   └── Specs/
│       └── SPEC-0001: Web Dashboard
├── worker/
│   ├── ADRs/
│   │   └── ADR-0001: Choose Redis for queues
│   └── Specs/
│       └── SPEC-0001: Job Processing
└── Overview (cross-module index page)

Each module's artifacts are transformed independently and placed under a module-named directory in the docs output. The index page lists all modules with artifact counts. When --module is provided, generate docs for that single module only (flat structure, no module subdirectory). When in single-module mode (no workspace), operate normally with the existing flat structure.

Step 1: Pre-flight Checks

• Check if Node.js is installed. If not, tell the user: "Node.js is required to run the docs site. Please install it from https://nodejs.org/ and re-run this command." and stop.
• Check if {adr-dir} has any ADR .md files
• Check if {spec-dir} has any spec directories (containing spec.md). Validate spec pairing per references/shared-patterns.md § "Spec Pairing Validation".
• If NEITHER has content, tell the user: "No ADRs or specs found. Create some first with /sdd:adr or /sdd:spec, then re-run /sdd:docs." and stop.
• If only one has content, proceed but note which is empty (e.g., "No specs found yet -- the docs site will only include ADRs for now.")

Step 2: Detect Existing Docusaurus Site and Upgrade State

2.1: Check for upgrade manifest

Check if .sdd-docs.json exists at the project root.

If .sdd-docs.json exists:

• Read and parse the manifest
• Check if the siteDir referenced in the manifest still exists on disk
  • If siteDir exists → enter Upgrade Mode (Step 3C). Skip Steps 2.2 and 2.3.
  • If siteDir is missing → warn the user: "Found .sdd-docs.json but the site directory {siteDir} no longer exists." Use AskUserQuestion to offer:
    • "Re-scaffold a new docs site" → proceed with Scaffold Mode (Step 3A)
    • "Cancel" → stop

If .sdd-docs.json does NOT exist, continue to Step 2.2.

2.2: Scan for existing Docusaurus sites

Scan the project root for directories containing docusaurus.config.ts or docusaurus.config.js:

find . -maxdepth 2 -name 'docusaurus.config.*' -not -path './docs-site/*' -not -path './node_modules/*' 2>/dev/null

2.3: Choose mode

If an existing docs site directory is detected (docs-site/ exists or an integration site was found in 2.2) but no .sdd-docs.json:

• Warn: "Upgrade tracking unavailable — .sdd-docs.json not found."
• Use AskUserQuestion to offer:
  • "Create manifest from current state" → compute SHA-256 checksums of all managed files in the existing site, write .sdd-docs.json using the current state as baseline, then enter Upgrade Mode (Step 3C)
  • "Continue without upgrade tracking" → proceed to mode selection below
  • "Cancel" → stop

If an existing non-scaffold Docusaurus site is found (from Step 2.2), use AskUserQuestion to let the user choose:

• Option A: "Integrate into {directory}" -- proceed with Integration Mode (Step 3B)
• Option B: "Scaffold a new docs site" -- proceed with Scaffold Mode (Step 3A)

If no existing site is found, proceed directly with Scaffold Mode (Step 3A).

---

Step 3A: Scaffold Mode

Read and follow the plugin's skills/docs/references/scaffold-mode.md for the full scaffold workflow. After completion, proceed to Step 4 below.

---

Step 3B: Integration Mode

Read and follow the plugin's skills/docs/references/integration-mode.md for the full integration workflow. After completion, proceed to Step 4 below.

---

Step 3C: Upgrade Mode

Read and follow the plugin's skills/docs/references/upgrade-mode.md for the full upgrade workflow. This handles manifest-based file management, conflict resolution, and new template detection.

---

Step 4: Create Manifest

Runs after Step 3A or 3B to establish upgrade tracking.

Determine managed files based on mode:

• Scaffold: files in docs-site/scripts/, docs-site/src/components/, docs-site/src/css/, docs-site/src/theme/
• Integration: files in {site}/plugins/sync-spec-docs/, {site}/src/components/design-docs/, {site}/src/css/design-docs.css, {site}/src/theme/MDXComponents.tsx (if created/modified)

Compute SHA-256 checksum for each file (shasum -a 256 {file-path}), then write .sdd-docs.json:

{
  "version": "<plugin version from .claude-plugin/plugin.json>",
  "mode": "scaffold" | "integration",
  "siteDir": "<relative path to site dir>",
  "createdAt": "<ISO 8601>",
  "updatedAt": "<ISO 8601>",
  "files": {
    "<relative-path>": { "checksum": "sha256:<hex-digest>", "managed": true }
  }
}

Tell the user: "Created .sdd-docs.json with {N} tracked files. Future runs of /sdd:docs will detect changes and offer upgrades."

Key Template Files Reference

Scaffold Mode Templates (templates/docusaurus/)

The templates directory contains production-ready versions of all files. The cp -r approach copies everything; you only need to customize docusaurus.config.ts and package.json.

Transform Scripts (scripts/)

• build-docs.js -- Orchestrator that runs all transforms
• transform-adrs.js -- Transforms ADR markdown to .mdx with badges, RFC 2119 keyword highlighting, cross-references
• transform-openspecs.js -- Transforms OpenSpec markdown to .mdx with requirement boxes, domain badges, RFC 2119 highlighting. Generates separate pages for spec.md and design.md within a directory-per-spec structure, with a _category_.json file per spec directory for Docusaurus sidebar configuration (Governing: ADR-0006, SPEC-0004)
• mdx-escape.js -- Escapes MDX v3 unsafe patterns (curly braces, angle brackets) while preserving JSX components
• build-spec-mapping.js -- Scans specs for SPEC ID prefixes and generates mapping JSON
• generate-index.js -- Creates the landing page (index.mdx) with links to ADRs and specs sections with counts

Integration Mode Templates (templates/integration/sync-spec-docs/)

A self-contained Docusaurus plugin with adapted transform scripts.

Plugin Entry

• index.js -- Docusaurus plugin that runs transforms during loadContent() and watches source files via getPathsToWatch()

Transform Scripts (lib/)

• transform-adrs.js -- ADR transforms with parameterized paths
• transform-openspecs.js -- OpenSpec transforms with parameterized paths
• transform-utils.js -- Shared utilities (RFC 2119 keywords, cross-references, link fixing)
• mdx-escape.js -- MDX v3 safety escaping
• build-spec-mapping.js -- Spec ID mapping (returns data instead of writing files)
• generate-index.js -- Index page generation with parameterized paths

Shared: React Components (templates/docusaurus/src/components/)

Used by both modes. In scaffold mode, they live at docs-site/src/components/. In integration mode, they're copied to {site}/src/components/design-docs/.

• StatusBadge.tsx -- Status with emoji (accepted, proposed, draft, etc.)
• DateBadge.tsx -- Date display with calendar emoji
• DomainBadge.tsx -- Domain/category badge
• PriorityBadge.tsx -- P0-P4 priority levels
• SeverityBadge.tsx -- Critical/High/Medium/Low/Info
• RFCLevelBadge.tsx -- Maps RFC 2119 keywords to severity colors
• RequirementBox.tsx -- Bordered container for spec requirements with ID anchors
• Field.tsx / FieldGroup.tsx -- Metadata label-value pairs

Shared: Theme and CSS (templates/docusaurus/src/)

• src/theme/MDXComponents.tsx -- Registers all custom components for use in MDX
• src/css/custom.css -- All badge, keyword, component, and dark mode styles

Rules

• Always read templates from the plugin directory, don't recreate from memory
• Configure the Docusaurus site for the current project (title, URLs, etc.)
• The transform scripts must work with the project's actual directory structure
• Don't include OpenAPI plugin config unless the project has an OpenAPI spec
• Keep spec-emojis.json and spec-mapping.json as generated files (populated by build-spec-mapping.js)
• In integration mode, NEVER overwrite the existing site's docusaurus.config.ts wholesale -- only add the plugin entry and CSS import
• In integration mode, ALWAYS namespace components under design-docs/ to avoid collisions with existing components
• In integration mode, generated files go to {site}/docs/architecture/ -- this directory is gitignored and regenerated on every build
• Always create .sdd-docs.json after a fresh scaffold or integration install (Step 4)
• Never delete or skip manifest creation -- it is required for upgrade tracking
• During upgrades (Step 3C), always ask before overwriting user-modified files
• The manifest files object uses project-root-relative paths as keys
• Checksum format is always sha256:<hex-digest> (lowercase hex)
• When creating a manifest from an existing site (Step 2.3 "Create manifest from current state"), set all files to managed: true and use their current checksums as the baseline
• In workspace aggregate mode, MUST organize docs navigation by module with per-module subdirectories (Governing: ADR-0016, SPEC-0014 REQ "Cross-Module Aggregation")
• In workspace aggregate mode, MUST generate a cross-module index page listing all modules with artifact counts
• In workspace aggregate mode, transform scripts run per-module with output directed to module-named subdirectories
• When --module is provided, generate docs for that single module only using flat structure
