Aquaria Documentation Skill

Expert architect for Aquaria project documentation. Enforces documentation principles, golden rules, folder structure, template compliance, and quality gates across all documentation files.

When to Apply

• User: "create documentation for X" "write docs following project standards" "validate documentation quality"
• Task: New feature docs, API reference, troubleshooting guides, or any documentation task
• Validation: Check if docs follow Aquaria standards before submitting
• Context: Always check AGENTS.md for current framework version and operational context

Non-Negotiable Golden Rules

Documentation Structure

• Hierarchy Principle: Every doc mirrors decision tree: Root (Overview) → Branches (Sections) → Leaves (Examples/Refs)
• Atomicity: Docs update in isolation (one file per topic) but link bidirectionally
• Template Enforcement: ALWAYS copy from /docs/.templates/ before writing

Mandatory Sections (Exact Order)

1. Overview: 1-paragraph purpose + prerequisites + learning outcomes
2. Quickstart: Single copy-pasteable code block (<5 min setup)
3. Deep Dive: Numbered steps + 1-2 edge cases per flow
4. Examples: 2-3 runnable snippets (basic, advanced, real-world)
5. References: Internal links + vetted externals

File Organization

• Naming: Kebab-case files (e.g., user-auth-guide.md)
• Path: /docs/{topic}/{file} (max 3 levels deep)
• TOC: Auto-generate for >500 words via <!-- TOC -->
• Extensions: Local imports MUST include .js extension

Quality Gates (Pre-Commit)

• pnpm run spellcheck passes
• pnpm run linkcheck passes
• Template used correctly
• All 5 mandatory sections present
• Quickstart code is runnable
• Examples have verified outputs

Workflow Decision Tree

Request: Create documentation for [topic]
A. Identify doc type
   - Feature guide → use guide.md template
   - API reference → use api-reference.md template
   - CLI command → use cli-reference.md template
   - Troubleshooting → use troubleshooting.md template
   - Design spec → use design-doc.md template
   - General → use base.md template

B. Copy template
   cp docs/.templates/{template}.md docs/{topic}/{filename}.md

C. Fill mandatory sections
   - Overview: purpose + prerequisites + learning outcomes
   - Quickstart: copy-pasteable code + expected output
   - Deep Dive: numbered steps + edge cases
   - Examples: 2-3 runnable snippets
   - References: internal + external links

D. Validate structure
   - H1 = Title matches filename
   - TOC present for >500 words
   - Heading hierarchy: H1 → H2 → H3
   - All placeholders replaced

E. Quality gates
   - spellcheck passes
   - linkcheck passes
   - Examples verified
   - Internal links resolve

Result: Compliant documentation file

Available Templates

Template	Use Case	Location
base.md	Universal template	docs/.templates/base.md
guide.md	Feature guides, tutorials	docs/.templates/guide.md
api-reference.md	API documentation	docs/.templates/api-reference.md
design-doc.md	Technical specs, ADRs	docs/.templates/design-doc.md
cli-reference.md	CLI tools	docs/.templates/cli-reference.md
troubleshooting.md	Error guides, FAQ	docs/.templates/troubleshooting.md

Folder Structure

docs/
  .templates/                    # Source of truth for all docs
    base.md
    guide.md
    api-reference.md
    design-doc.md
    cli-reference.md
    troubleshooting.md
    README.md                    # Template documentation
  {topic}/                       # Max 3 levels deep
    {file-name}.md               # Kebab-case naming
  README.md                      # Docs index
  DOCUMENTATION_GUIDELINES.md    # Master rules

Code Conventions Integration

TypeScript/Code Style

• Files: kebab-case.ts (e.g., agentic-orchestrator.ts)
• Classes: PascalCase
• Variables/Functions: camelCase
• Constants: UPPER_SNAKE_CASE
• Imports: MUST include .js extension

Path Aliases

• #/* alias prefix maps to packages/aquaria-workflows/src/
• Examples: #/capabilities/*, #/tools/*, #/orchestrator/*

Zod Integration

• Define schemas alongside types: PlanNodeSchema and PlanNode interface
• Use z.infer<typeof Schema> for type inference
• Runtime validation for all inputs

JSDoc Mandatory

All exported symbols require:

• Description
• @param tags
• @returns tags
• @example tags (highly encouraged)

Live Service Context

Critical: Aquaria is now in live production service territory (added 2025-12-30).

Production documentation MUST include:

• Deployment considerations
• Cost implications
• Operational discipline notes
• Safety gates for production changes

Generated Files

DO NOT EDIT - Regenerate with pnpm aquaria codegen:

• Tool Catalogs: packages/aquaria-workflows/src/tools/catalog.{node,browser,edge}.ts
• Capability Catalogs: packages/aquaria-workflows/src/capabilities/capability-catalog.generated.ts
• JSON Schemas: packages/aquaria-schemas/schemas/*.schema.json

Examples

Input: Create documentation for new workflow feature
Output:

1. Copy template: cp docs/.templates/guide.md docs/workflows/new-feature.md
2. Fill sections following Golden Rules
3. Add runnable code examples from examples/workflows/
4. Validate with: pnpm run spellcheck && pnpm run linkcheck

Input: Validate existing documentation
Output: Run quality checklist:

• Template used
• All 5 sections present
• TOC generated for >500 words
• Quickstart is copy-pasteable
• Examples have expected output
• Internal links resolve
• External links vetted
• Spellcheck passes
• Linkcheck passes

Input: Update docs after code change
Output:

1. grep for related terms in codebase
2. Append to docs/CHANGELOG.md in format: ## YYYY-MM-DD - [File]: [1-sentence summary]
3. Update affected documentation sections
4. Validate all quality gates

Quality Gate Commands

# Spell check
pnpm run spellcheck

# Link check
pnpm run linkcheck

# Generate TOC
pnpm run toc

# Validate structure
pnpm run docs:validate
