Documentation Authoring Master
Expert guidance for creating structured, high-quality documentation across all types of technical and business documents.
- Leverage native parallel subagent dispatch and 200k+ context windows where available.
Activation Conditions
Use symptom -> action triggers: when one matches, apply this skill and verify with the protocol below.
Trigger Conditions:
- User mentions writing documentation: "write a doc", "draft a proposal", "create a spec", "write up"
- User mentions specific doc types: "PRD", "design doc", "decision doc", "RFC"
- User asks to "create an implementation plan", "document requirements", "plan a feature"
- Creating technical specifications or business requirements
- Starting a new product or feature development cycle
- Translating vague ideas into concrete technical specifications
- Stakeholders need unified "source of truth" for project scope
Part 2: Context Gathering
Initial Questions
Start by asking for meta-context about the document:
What type of document is this?
- Technical spec, decision doc, proposal, RFC, PRD, knowledge base
Who's the primary audience?
- Developers, executives, stakeholders, end-users? Understanding affects tone and depth
What's the desired impact when someone reads this?
- Make a decision, implement a feature, understand a concept?
Is there a template or specific format to follow?
- Company templates, industry standards, regulatory requirements
Any other constraints or context to know?
- Deadlines, sensitive information, existing related documents
Inform them they can answer in shorthand or dump information however works best for them.
Template Handling
If user provides a template:
- Analyze structure and requirements
- Adapt co-authoring workflow to template format
- Ensure all required sections are covered
If user mentions editing an existing document:
- Fetch the existing document
- Understand current state and gaps
- Plan revisions strategically
Part 3: Refinement & Structure
Collaborative Building
Process:
- Brainstorm each section together - let ideas flow without judgment
- Organize and refine - structure ideas into coherent sections
- Edit for clarity - improve readability and flow
- Add professional polish - formatting, consistency, tone
Guiding Principles:
- Active voice: Use direct, clear language
- Show, don't just tell: Use examples and scenarios
- Progressive disclosure: Start with overview, then dive deeper
- Visual aids: Include diagrams, tables, and examples where helpful
Section-by-Section Approach
Work through document methodically:
## Recommended Section Structure
### 1. Executive Summary (for decision-makers)
- What is this about?
- Why does it matter?
- What are we recommending/deciding?
### 2. Background & Context (for implementers)
- What led us here?
- What problem are we solving?
- What constraints exist?
### 3. Requirements/Objectives
- What must we achieve?
- What are success criteria?
- What are non-goals?
### 4. Proposed Solution/Design
- What are we proposing?
- How does it work?
- What are alternatives considered?
### 5. Implementation Plan
- How do we build this?
- What are the steps?
- Who needs to do what?
### 6. Risks & Considerations
- What could go wrong?
- How do we mitigate?
- What decisions are still needed?
Part 4: Reader Testing
The Fresh Eye Test
Before finalizing, put yourself in the reader's shoes:
Test Questions:
- Can I understand the goal without knowing context?
- Are technical terms explained or linked?
- Is there a logical flow from problem to solution?
- Would a skeptical reader be convinced?
- Is action clear - what should I do next?
Blind Spot Detection
Common issues to catch:
- Context assumptions: "We already discussed this" but wasn't documented
- Missing alternatives: Only one option presented (shows lack of thoroughness)
- Unanswered questions: Reader left with "what about X?"
- Unclear responsibilities: Who needs to do what is vague
- Missing examples: Abstract concepts without concrete illustration
Part 5: Product Requirements Document (PRD)
PRD Structure
When users specifically request PRDs or feature planning, use this structure:
# [Feature/Product Name] - PRD
## Executive Summary
**Goal**: [What problem are we solving?]
**Impact**: [Why does this matter now?]
**Success Metrics**: [How will we know it worked?]
## Background
**Current State**: [What's the situation today?]
**Problem Statement**: [What pain points exist?]
**Constraints**: [Budget, timeline, tech stack limitations?]
## Requirements
### Functional Requirements
- User stories with acceptance criteria
- Core features and capabilities
- Integration requirements
### Non-Functional Requirements
- Performance requirements
- Security requirements
- Compliance and regulatory needs
### User Stories
As a [persona], I want to [action], So that [benefit].
**Acceptance Criteria**:
- [ ] [Specific, measurable criterion]
- [ ] [Another criterion]
Proposed Solution
Architecture Overview
[High-level system architecture or approach]
Technical Specifications
[API contracts, data models, interfaces]
UI/UX Requirements
[Wireframes or flow descriptions if applicable]
Implementation Plan
Phases
| Phase | Tasks | Owners | Timeline |
|---|---|---|---|
| Phase 1 | |||
| Phase 2 |

- Other teams or systems
- Third-party libraries
Risk Analysis
| Risk | Impact | Probability | Mitigation |
|---|---|---|---|
| [Risk] | High/Med/Low | High/Med/Low | [Mitigation] |
Alternatives Considered
| Option | Pros | Cons | Why Not Chosen |
|---|---|---|---|
| Alt 1 |
Success Criteria
Quantitative
- [Measurable metric: e.g., "reduce load time by 50%"]
- [Another metric]
Qualitative
- [User feedback threshold]
- [Stakeholder alignment]
Open Questions
- [Decision still needed]
- [Information to gather]
### PRD Creation Workflow
**Phase 1: Discovery (The Interview)**
Before writing a single line, you **MUST** interrogate user to fill knowledge gaps. Do not assume context.
**Ask about:**
- **The Core Problem**: Why are we building this now?
- **Success Metrics**: How do we know it worked?
- **Constraints**: Budget, tech stack, or deadline?
- **Stakeholders**: Who needs to approve? Who will use?
**Phase 2: Analysis & Scoping**
Synthesize user input. Identify dependencies and hidden complexities.
- **Map out User Flow**
- **Define Non-Goals** to protect timeline
**Phase 3: Technical Drafting**
Generate document using strict structure above.

## Part 6: Common Document Types
### Implementation Plans
**Purpose**: Guide building process with clear phases, responsibilities, and timeline.
**Structure:**
- **Overview**: What are we building and why?
- **Phases**: Break into logical chunks with dependencies
- **Tasks**: Trackable, specific implementation items
- **Timeline**: Realistic dates with buffers
- **Dependencies**: What must happen before what?
### Design Docs
**Purpose**: Document technical decisions and architecture.
**Structure:**
- **Problem Statement**: What problem are we solving?
- **Alternatives**: What did we consider?
- **Decision**: What did we choose and why?
- **Implications**: What does this mean for the system?
- **Risks**: What could go wrong?
### Decision Records
**Purpose**: Capture important decisions for future reference.
**Template:**
```markdown
### Decision - [DATE]
**Decision**: [What was decided]
**Context**: [Situation and driving data]
**Options**: [Alternatives with pros/cons]
**Rationale**: [Why selected option is superior]
**Impact**: [Anticipated consequences]
**Review**: [Reassessment conditions/trigger]
Knowledge Base Articles
Purpose: Reusable reference material, not project-specific docs.
Structure:
- Quick Reference: TL;DR summary at top
- Problem: What question does this answer?
- Solution: How do you solve it?
- Examples: Concrete, runnable examples
- Common Pitfalls: What mistakes do people make?
- Related Topics: Links to related info
Part 7: Best Practices
For All Documentation
✅ DO:
- Use active voice and clear language
- Structure information progressively (simple to complex)
- Include examples and concrete scenarios
- Define terms before using them
- Add diagrams for complex systems
- Maintain consistent formatting and style
❌ DON'T:
- Write without clear audience in mind
- Mix jargon without explanation
- Skip alternatives or trade-offs analysis
- Assume readers have context they don't
- Create long paragraphs without breaks
For Technical Docs
- Include code snippets that actually run
- Link to external references for deeper dives
- Use standard terminology when possible
- Version specific code/commands (e.g., "for node v16+")
For Business/Stakeholder Docs
- Start with executive summary
- Use business impact metrics
- Hide unnecessary technical detail
- Include clear next steps or approvals needed
- Highlight risks and mitigations prominently
Part 8: Action Documentation Format
Use this format for tracking implementation work and decisions:
[TYPE] - [ACTION] - [TIMESTAMP]
Objective: [Goal being accomplished]
Context: [Current state, requirements, reference to prior steps]
Decision: [Approach chosen and rationale]
Execution: [Steps taken with parameters and commands]
Output: [Complete results, logs, metrics]
Validation: [Success verification and results]
Next: [Continuation plan to next action]
Part 9: Summary Formats
Streamlined Action Log (for changelogs)
[TYPE][TIMESTAMP] Goal: [X] → Action: [Y] → Result: [Z] → Next: [W]
Quick Summary (for updates)
What: [Brief description] Why: [Context/rationale] How: [Approach taken] Status: [Current state] Next: [Upcoming step]
Documentation Stack Reference
Inherit the shared stack from documentation-patterns: source-of-truth discovery, audience framing, structure selection, verification, and freshness checks. Keep this skill focused on drafting and refinement instead of restating the full stack.
Cross-Client Portability
This skill is written to stay usable across GitHub Copilot, Claude Code, and Codex.
- GitHub Copilot: keep the folder in a Copilot-visible skill path or wrap the workflow in project instructions when folder discovery is unavailable.
- Claude Code: keep the folder in a local skills directory or a compatible plugin source.
- Codex: install or sync the folder into
$CODEX_HOME/skills/documentation-authoringand restart Codex after major changes.
MCP Availability And Fallback
Preferred MCP Server: None required
- Fallback prompt: "Use the Documentation Authoring Master skill without MCP. Rely on its local instructions, bundled resources, standard shell or editor tools, and direct verification. Show the evidence used before concluding."
- Do not claim an MCP operation was used when the active host does not expose it.
- Treat local files, tests, rendered outputs, logs, or screenshots as the fallback evidence path.
Anti-Patterns
- Writing for the author instead of the reader: It bakes in unstated context and leaves the actual audience unsure what to do next.
- Skipping concrete examples or commands: Abstract guidance is easy to approve and hard to apply correctly.
- Letting links, screenshots, or versions drift: Polished formatting does not help if the instructions are no longer true.
Verification Protocol
Before claiming "skill applied successfully":
- Pass/fail: The Documentation Authoring output identifies audience, purpose, source of truth, and freshness requirements.
- Pass/fail: Shared documentation-stack guidance is referenced instead of duplicating another documentation skill.
- Pass/fail: Claims, links, commands, examples, and screenshots are verified or explicitly marked unverified.
- Pressure-test scenario: Apply the skill to a doc request with a stale command, missing owner, and conflicting audience.
- Success metric: Zero undocumented assumptions; every reader-facing claim is sourced or scoped.
