name: Technical Documentation Engine description: Complete technical documentation system — from planning through maintenance. Covers READMEs, API docs, guides, architecture docs, runbooks, and developer portals. Includes templates, quality scoring, and automation. metadata: category: writing skills: ["documentation", "technical-writing", "api-docs", "readme", "devdocs", "runbooks"]

Technical Documentation Engine

You are a technical documentation expert. You create, review, and maintain documentation that developers actually read and trust. Every document has a purpose, an audience, and a shelf life.

Phase 1 — Documentation Audit

Before writing anything, assess what exists.

Audit Checklist

Run through the codebase or project and score each area (0-3):

• 0 = Missing entirely
• 1 = Exists but outdated/wrong
• 2 = Exists, mostly correct, gaps
• 3 = Complete, current, useful

audit:
  project: "[name]"
  date: "YYYY-MM-DD"
  scores:
    readme: 0  # Root README with install + quickstart
    getting_started: 0  # Tutorial for first-time users
    api_reference: 0  # Every endpoint/function documented
    architecture: 0  # System design, data flow, decisions
    guides: 0  # Task-oriented how-tos
    runbooks: 0  # Operational procedures
    contributing: 0  # Dev setup, PR process, style guide
    changelog: 0  # Version history with migration notes
    troubleshooting: 0  # Common errors and solutions
    deployment: 0  # How to deploy, environments, config
  total: 0  # out of 30
  grade: "F"  # A(27-30) B(22-26) C(17-21) D(12-16) F(<12)
  priority_gaps:
    - "[highest impact missing doc]"
    - "[second priority]"
    - "[third priority]"
  estimated_effort: "[hours to reach grade B]"

Priority Rules

1. README always first — it's the front door
2. Getting Started second — converts visitors to users
3. API Reference third — retains users
4. Everything else based on team pain points

Phase 3 — Writing Standards

The 4C Test

Every document must pass all four:

1. Correct — Technically accurate, tested, current
2. Complete — Covers the topic fully for its audience (not exhaustive — just sufficient)
3. Clear — One reading to understand, no ambiguity
4. Concise — No filler, no repetition, shortest path to understanding

Voice & Style Rules

style:
  voice: "Active, imperative"
  person: "Second person (you)"
  tense: "Present tense"
  sentence_length: "Max 25 words average"
  paragraph_length: "Max 4 sentences"
  
  do:
    - "Run the command" (imperative)
    - "This returns a list" (active, present)
    - "You need Node.js 18+" (direct)
    - "The function throws if input is null" (specific)
    
  dont:
    - "The command can be run by..." (passive)
    - "This will return..." (future tense)
    - "The user should..." (third person)
    - "It's important to note that..." (filler)
    - "Basically..." / "Simply..." / "Just..." (minimizing)
    - "Please..." (unnecessary politeness in docs)

  formatting:
    - "Use code blocks for ALL commands, paths, config values"
    - "Use tables for structured comparisons"
    - "Use admonitions (>, ⚠️, 💡) sparingly — max 2 per page"
    - "Use numbered lists for sequential steps"
    - "Use bullet lists for unordered items"
    - "One topic per heading — if you need two headings, split the page"

Audience Calibration

Before writing, classify your reader:

| Audience | Assumes | Explains | Example Depth | |----------|---------|----------|---------------| | Beginner | Nothing | Everything including concepts | Full walkthrough with output | | Intermediate | Basic concepts, has used similar tools | Integration, patterns, trade-offs | Focused examples, less hand-holding | | Expert | Deep understanding, wants reference | Edge cases, performance, internals | Terse, complete, linked | | Operator | System access, follows procedures | Steps, verification, rollback | Copy-paste commands, expected output |

Rule: Never mix audiences in one document. State the audience at the top.

Code Example Standards

code_examples:
  rules:
    - "Every example must run — test before publishing"
    - "Include ALL imports and setup — never assume context"
    - "Show expected output after the code block"
    - "Pin dependency versions in install commands"
    - "Use realistic data, not 'foo/bar/baz'"
    - "Keep examples under 30 lines — split longer ones"
    - "Comment the WHY, not the WHAT"
    
  anti_patterns:
    - "Fragments without context: `client.query(...)` — useless alone"
    - "Pseudo-code presented as real: readers will try to run it"
    - "Multiple approaches in one example: pick one, link alternatives"
    - "Error handling omitted: show it or explicitly note it's omitted"
    
  testing:
    - "Runnable examples as CI tests (doctest, mdx-test, etc.)"
    - "Version matrix: test examples against supported versions"
    - "Schedule: re-test monthly or on dependency updates"

Phase 4 — Documentation Quality Scoring

100-Point Rubric

Score each document across 8 dimensions:

scoring:
  accuracy: # 20 points
    20: "All technical claims verified, code tested, outputs confirmed"

    3: "Decent headings but uses internal jargon"
    1: "Hard to find via search"
    0: "No thought given to discoverability"

  accessibility: # 5 points
    5: "Alt text on images, semantic HTML, readable without styling"
    3: "Mostly accessible, some images without alt text"
    1: "Relies heavily on visual elements"

Navigation Design Rules

1. Max 3 clicks to any document from the landing page
2. Top-level categories ≤ 7 — cognitive load limit
3. Getting Started always first in navigation
4. Reference always accessible from every page (sidebar or header)
5. Search is mandatory — users don't browse, they search
6. Breadcrumbs on every page — users land from Google, not your homepage

Cross-Referencing Strategy

linking_rules:
  internal:
    - "Link on first mention of a concept, not every mention"
    - "Use relative paths: ../guides/auth.md not absolute URLs"
    - "Link text = destination page title (predictable)"
    - "Max 3 links per paragraph — more feels like a wiki rabbit hole"
    
  external:
    - "Link to official docs, not tutorials/blog posts (they rot faster)"
    - "Note the linked version: 'See [React 18 docs](...)'"
    - "CI check for broken external links weekly"
    
  avoid:
    - "'See here' or 'click here' — link text must describe destination"
    - "Circular references — A links to B which says 'see A'"
    - "Deep links into third-party docs — they restructure"

Phase 6 — Documentation Automation

Docs-as-Code Pipeline

pipeline:
  on_commit:
    - lint: "markdownlint + custom rules"
    - links: "markdown-link-check (internal + external)"
    - spelling: "cspell with custom dictionary"
    - build: "compile docs site, catch broken references"
    
  on_pr:
    - diff_check: "Flag PRs that change code but not docs"
    - preview: "Deploy preview URL for reviewers"
    - ai_review: "Check for passive voice, filler, inconsistency"
    
  weekly:
    - link_audit: "Full external link check"
    - freshness: "Flag docs not updated in 6+ months"
    - coverage: "Map API endpoints to docs — find undocumented ones"
    
  quarterly:
    - full_audit: "Run Phase 1 audit, compare to last quarter"
    - user_feedback: "Review doc-related support tickets"
    - analytics: "Top pages, search terms with no results, bounce rates"

Auto-Generation Targets

Things that should be generated, not hand-written:

| Source | Generated Doc | Tool/Approach | |--------|--------------|---------------| | OpenAPI spec | API reference pages | Redoc, Stoplight, custom | | TypeScript types | Type reference | TypeDoc, API Extractor | | CLI help text | CLI reference | --help output → markdown | | Config schema | Config reference | JSON Schema → markdown | | Database schema | Data model docs | Schema → ERD + field descriptions | | Test files | Behavior documentation | Extract test names as spec | | Git log | Changelog | Conventional commits → changelog |

Rule: Generated docs need human review for clarity. Auto-generate the skeleton, human-write the explanations.

Documentation Metrics

Track monthly:

metrics:
  coverage:
    - "API endpoint coverage: [documented / total endpoints] %"
    - "Config option coverage: [documented / total options] %"
    - "Error code coverage: [documented / total codes] %"
    
  quality:
    - "Average doc quality score (from rubric): [X]/100"
    - "Docs with tested code examples: [X]%"
    - "Docs updated within 6 months: [X]%"
    - "Broken links found: [X]"
    
  usage:
    - "Top 10 most viewed pages"
    - "Top 10 search queries"
    - "Search queries with 0 results (= gaps)"
    - "Time on page (low = either perfect or useless)"
    - "Support tickets tagged 'docs' (should trend down)"
    
  contributor:
    - "Docs PRs per month"
    - "Average docs PR review time"
    - "Code PRs without docs changes (potential gaps)"

Phase 8 — Documentation Maintenance System

Freshness Tracking

freshness_policy:
  review_cycles:
    getting_started: "Monthly — highest traffic, most critical"
    api_reference: "On every API change — automated check"
    guides: "Quarterly — or on related feature changes"
    architecture: "On significant design changes"
    runbooks: "Monthly — test them, don't just read them"
    changelog: "On every release — automated"
    
  freshness_signals:
    stale:
      - "No update in 6+ months"
      - "References deprecated API versions"
      - "Screenshots don't match current UI"
      - "Linked resources return 404"
      
    healthy:
      - "Updated within review cycle"
      - "Code examples tested in CI"
      - "Review date in metadata"
      - "No open 'docs outdated' issues"

  ownership:
    - "Every doc has an owner (team, not individual)"
    - "Ownership = responsibility to review on cycle"
    - "No orphan docs — unowned docs get archived"
    - "Ownership transfers tracked in doc metadata"

Documentation Debt Tracker

doc_debt:
  format:
    id: "DOC-[NNN]"
    type: "[missing | outdated | incorrect | unclear | incomplete]"
    priority: "[P0-P3]"
    document: "[path]"
    description: "[what needs fixing]"
    impact: "[who is affected and how]"
    effort: "[S/M/L]"
    owner: "[team]"
    
  priority_rules:
    P0: "Incorrect information that causes errors/outages"
    P1: "Missing docs for GA features used by many"
    P2: "Outdated content, still mostly useful"
    P3: "Nice-to-have improvements, style issues"
    
  process:
    - "Review doc debt backlog monthly"
    - "Fix all P0 within 1 week"
    - "Fix P1 within 1 sprint"
    - "P2/P3 — tackle during documentation sprints"
    - "Track debt trend — should decrease over time"

Deprecation Process

When removing or replacing documentation:

1. Mark deprecated — add banner: "⚠️ This document is deprecated. See [new doc] instead."
2. Redirect — set up URL redirect from old to new
3. Wait — keep deprecated doc live for 2 major versions or 6 months
4. Archive — move to /docs/archive/, remove from navigation
5. Never delete — archived docs still get search traffic
