Workspace Documentation

Knowledge Capture

Transforms conversations, discussions, and insights into structured documentation in your Notion workspace. Captures knowledge from chat context, formats it appropriately, and saves it to the right location with proper organization and linking.

Quick Start

When asked to save information to Notion:

1. Extract content: Identify key information from conversation context 2. Structure information: Organize into appropriate documentation format 3. Determine location: Use Notion:notion-search to find appropriate wiki page/database 4. Create page: Use Notion:notion-create-pages to save content 5. Make discoverable: Link from relevant hub pages, add to databases, or update wiki navigation so others can find it

Knowledge Capture Workflow

Step 1: Identify content to capture

From conversation context, extract:
- Key concepts and definitions
- Decisions made and rationale
- How-to information and procedures
- Important insights or learnings
- Q&A pairs
- Examples and use cases

Step 2: Determine content type

Classify the knowledge:
- Concept/Definition
- How-to Guide
- Decision Record
- FAQ Entry
- Meeting Summary
- Learning/Post-mortem
- Reference Documentation

Step 3: Structure the content

Format appropriately based on content type:
- Use templates for consistency
- Add clear headings and sections
- Include examples where helpful
- Add relevant metadata
- Link to related pages

Step 4: Determine destination

Where to save:
- Wiki page (general knowledge base)
- Specific project page (project-specific knowledge)
- Documentation database (structured docs)
- FAQ database (questions and answers)
- Decision log (architecture/product decisions)
- Team wiki (team-specific knowledge)

Step 5: Create the page

Use Notion:notion-create-pages:
- Set appropriate title
- Use structured content from template
- Set properties if in database
- Add tags/categories
- Link to related pages

Step 6: Make content discoverable

Link the new page so others can find it:

1. Update hub/index pages:
   - Add link to wiki table of contents page
   - Add link from relevant project page
   - Add link from category/topic page (e.g., "Engineering Docs")

2. If page is in a database:
   - Set appropriate tags/categories
   - Set status (e.g., "Published")
   - Add to relevant views

3. Optionally update parent page:
   - If saved under a project, add to project's "Documentation" section
   - If in team wiki, ensure it's linked from team homepage

Example:
Notion:notion-update-page
page_id: "team-wiki-homepage-id"
command: "insert_content_after"
selection_with_ellipsis: "## How-To Guides..."
new_str: "- <mention-page url='...'>How to Deploy to Production</mention-page>"

This step ensures the knowledge doesn't become "orphaned" - it's properly connected to your workspace's navigation structure.

Content Types

Choose appropriate structure based on content:

Concept: Overview → Definition → Characteristics → Examples → Use Cases → Related How-To: Overview → Prerequisites → Steps (numbered) → Verification → Troubleshooting → Related Decision: Context → Decision → Rationale → Options Considered → Consequences → Implementation FAQ: Short Answer → Detailed Explanation → Examples → When to Use → Related Questions Learning: What Happened → What Went Well → What Didn't → Root Causes → Learnings → Actions

Destination Patterns

General Wiki: Standalone page → add to index → tag → link from related pages

Project Wiki: Child of project page → link from project overview → tag with project name

Documentation Database: Use properties (Title, Type, Category, Tags, Last Updated, Owner)

Decision Log Database: Use properties (Decision, Date, Status, Domain, Deciders, Impact)

FAQ Database: Use properties (Question, Category, Tags, Last Reviewed, Useful Count)

See reference/database-best-practices.md for database selection guide and individual schema files.

Content Extraction from Conversations

Chat Discussion: Key points, conclusions, resources, action items, Q&A

Problem-Solving: Problem statement, approaches tried, solution, why it worked, future considerations

Knowledge Sharing: Concept explained, examples, best practices, common pitfalls, resources

Decision Discussion: Question, options, trade-offs, decision, rationale, next steps

Formatting Best Practices

Structure: Use # (title), ## (sections), ### (subsections) consistently

Writing: Start with overview, use bullets, keep paragraphs short, add examples

Linking: Link related pages, mention people, reference resources, create bidirectional links

Metadata: Include date, author, tags, status

Searchability: Clear titles, natural keywords, common search tags, image alt-text

Indexing and Organization

Wiki Index: Organize by sections (Getting Started, How-To Guides, Reference, FAQs, Decisions) with page links

Category Pages: Create landing pages with overview, doc links, and recent updates

Tagging Strategy: Use consistent tags for technology/tools, topics, audience, and status

Update Management

Create New: Content is substantive (>2 paragraphs), will be referenced multiple times, part of knowledge base, needs independent discovery

Update Existing: Adding to existing topic, correcting info, expanding concept, updating for changes

Versioning: Add update history section for significant changes (date, author, what changed, why)

Best Practices

1. Capture promptly: Document while context is fresh 2. Structure consistently: Use templates for similar content 3. Link extensively: Connect related knowledge 4. Write for discovery: Use searchable titles and tags 5. Include context: Why this matters, when to use 6. Add examples: Concrete examples aid understanding 7. Maintain: Review and update periodically 8. Get feedback: Ask if documentation is helpful

Advanced Features

Documentation databases: See reference/database-best-practices.md for database schema patterns.

Common Issues

"Not sure where to save": Default to general wiki, can move later "Content is fragmentary": Group related fragments into cohesive doc "Already exists": Search first, update existing if appropriate "Too informal": Clean up language while preserving insights

Examples

See examples/ for complete workflows:

• examples/conversation-to-faq.md - FAQ from Q&A
• examples/decision-capture.md - Decision record
• examples/how-to-guide.md - How-to from discussion

You need to kill the existing process before deploying again.\n\n## Detailed Explanation\n\nWhen you deploy the application, it tries to bind to a specific port (e.g., port 3000). If a previous deployment didn't shut down cleanly, that process may still be running and holding the port. This prevents the new deployment from starting.\n\nCommon causes:\n- Previous deployment crashed without cleanup\n- Manual node process started and forgotten\n- PM2 or other process manager didn't restart properly\n- Multiple deployments attempted simultaneously\n\n## Solution\n\n### Option 1: Kill the process using the port\n\n``bash\n# Find and kill process on port 3000\nlsof -ti:3000 | xargs kill -9\n`\n\nReplace 3000 with your application's port number.\n\n### Option 2: If using PM2\n\n`bash\n# Restart the application\npm2 restart app\n\n# Or delete and restart\npm2 delete app\npm2 start app.js --name app\n`\n\n### Option 3: Check all node processes\n\n`bash\n# List all node processes\nps aux | grep node\n\n# Kill specific process by PID\nkill -9 <PID>\n`\n\n## Prevention\n\n1. **Use process managers**: PM2, systemd, or Docker handle cleanup automatically\n2. **Graceful shutdown**: Implement proper shutdown handlers in your app\n3. **Health checks**: Monitor if previous deployment shut down before starting new one\n\n`javascript\n// Graceful shutdown example\nprocess.on('SIGTERM', () => {\n server.close(() => {\n console.log('Server closed');\n process.exit(0);\n });\n});\n`\n\n## Verification\n\nAfter killing the process, verify the port is free:\n\n`bash\nlsof -ti:3000\n# Should return nothing if port is free\n`\n\n## Related Questions\n- <mention-page url=\"...\">How do I check what's using a port?</mention-page>\n- <mention-page url=\"...\">How do I configure the application port?</mention-page>\n- <mention-page url=\"...\">PM2 deployment best practices</mention-page>\n\n## Last Updated\nOctober 14, 2025" }] ```

Content sample:

# Migrate Customer-Facing API to GraphQL

## Context

Our REST API has grown to 50+ endpoints with inconsistent patterns. Frontend and mobile teams request new endpoints frequently, leading to:

- API bloat and maintenance burden
- Over-fetching/under-fetching data
- Slow iteration on client features
- Inconsistent error handling

## Decision

Migrate customer-facing API from REST to GraphQL while maintaining REST for internal services.

## Rationale

**Why GraphQL**:

- Clients fetch exactly what they need (no over/under-fetching)
- Single endpoint, self-documenting schema
- Type safety with code generation
- Better developer experience
- Industry standard for client-facing APIs

## Options Considered

### Option A: Keep REST (Status Quo)

**Pros**: No migration cost, team familiar
**Cons**: Doesn't solve core problems, maintenance keeps growing
**Decision**: Rejected - doesn't address root cause

### Option B: gRPC

**Pros**: Performance, strong typing
**Cons**: Browser support issues, steeper learning curve, not designed for client-facing
**Decision**: Rejected - better for internal services

### Option C: GraphQL

**Pros**: Solves over/under-fetching, great DX, strong ecosystem
**Cons**: Learning curve, caching complexity, migration effort
**Decision**: **Accepted**

## Consequences

**Positive**:

- Faster frontend/mobile development
- Reduced API maintenance burden
- Better type safety and tooling
- Single endpoint simplifies deployment

**Negative**:

- 3-4 month migration timeline
- Team needs training
- Need to solve caching strategy
- Monitoring/debugging patterns different

## Implementation Plan

1. GraphQL server setup (Apollo Server)
2. Schema design workshop
3. Gradual migration (start with new features)
4. Dual-run period (both REST and GraphQL)
5. Deprecate old REST endpoints

**Timeline**: Start Q4 2025, complete Q1 2026
**Owner**: Backend team lead

## Success Metrics

- API response times improve 30%
- Client fetch efficiency (less data transferred)
- Reduced new endpoint requests
- Developer satisfaction scores

5. Make Discoverable

Added link from Architecture Wiki and notified team in Slack.

Key Success Factors

• Captured decision while context fresh
• Documented alternatives considered
• Included both pros and cons
• Clear implementation plan
• Saved to decision log for future reference
• Made discoverable for team

• [ ] All pods healthy in k8s dashboard
• [ ] Error rate < 0.1% in last 10 min
• [ ] Response time p95 < 500ms
• [ ] Test login flow
• [ ] Check Slack #alerts channel

Troubleshooting

Health checks failing → Check pod logs: kubectl logs -f deployment/api -n production

Migration errors → Rollback: Revert tag, migrations auto-rollback

High error rate → Emergency rollback: Previous tag auto-deploys via GitHub Actions

Best Practices

• Deploy during low-traffic hours (2-4am PST)
• Have 2 engineers available
• Monitor for 30 min post-deploy
• Update #engineering Slack with deploy notice

Database Best Practices

General guidance for creating and maintaining knowledge capture databases.

Core Principles

1. Keep It Simple

• Start with core properties
• Add more only when needed
• Don't over-engineer

2. Use Consistent Naming

• Title property for main identifier
• Status for lifecycle tracking
• Tags for flexible categorization
• Owner for accountability

3. Include Metadata

• Created/Updated timestamps
• Owner or maintainer
• Last reviewed dates
• Status indicators

4. Enable Discovery

• Use tags liberally
• Create helpful views
• Link related content
• Use clear titles

5. Plan for Scale

• Consider filters early
• Use relations for connections
• Think about search
• Organize with categories

Creating a Database

Using Notion:notion-create-database

Example for documentation database:

{
  "parent": {"page_id": "wiki-page-id"},
  "title": [{"text": {"content": "Team Documentation"}}],
  "properties": {
    "Type": {
      "select": {
        "options": [
          {"name": "How-To", "color": "blue"},
          {"name": "Concept", "color": "green"},
          {"name": "Reference", "color": "gray"},
          {"name": "FAQ", "color": "yellow"}
        ]
      }
    },
    "Category": {
      "select": {
        "options": [
          {"name": "Engineering", "color": "red"},
          {"name": "Product", "color": "purple"},
          {"name": "Design", "color": "pink"}
        ]
      }
    },
    "Tags": {"multi_select": {"options": []}},
    "Owner": {"people": {}},
    "Status": {
      "select": {
        "options": [
          {"name": "Draft", "color": "gray"},
          {"name": "Final", "color": "green"},
          {"name": "Deprecated", "color": "red"}
        ]
      }
    }
  }
}

Fetching Database Schema

Before creating pages, always fetch database to get schema:

Notion:notion-fetch
id: "database-url-or-id"

This returns the exact property names and types to use.

Database Selection Guide

Tips

1. Start with general documentation database - most flexible 2. Add specialized databases as needs emerge (FAQ, Decisions) 3. Use relations to connect related docs 4. Create views for common use cases 5. Review properties quarterly - remove unused ones 6. Document the schema in database description 7. Train team on property usage and conventions

Decision Log Database (ADR - Architecture Decision Records)

Purpose: Track important decisions with context and rationale.

Schema

Usage

Create decision records with properties:
{
  "Decision": "Use PostgreSQL for Primary Database",
  "Date": "2025-10-15",
  "Status": "Accepted",
  "Domain": "Architecture",
  "Impact": "High",
  "Deciders": [tech_lead, architect],
  "Stakeholders": [eng_team]
}

Content Template

Each decision page should include:

• Context: Why this decision was needed
• Decision: What was decided
• Rationale: Why this option was chosen
• Options Considered: Alternatives and trade-offs
• Consequences: Expected outcomes (positive and negative)
• Implementation: How decision will be executed

Views

Recent Decisions: Sort by Date descending Active Decisions: Filter where Status = "Accepted" By Domain: Group by Domain High Impact: Filter where Impact = "High" Pending: Filter where Status = "Proposed"

Best Practices

1. Document immediately: Record decisions when made, while context is fresh 2. Include alternatives: Show what was considered and why it wasn't chosen 3. Track superseded decisions: Update status when decisions change 4. Link related decisions: Use relations to show dependencies 5. Review periodically: Check if old decisions are still valid

General Documentation Database

Purpose: Store all types of documentation in a searchable, organized database.

Schema

Usage

Create pages with properties:
{
  "Title": "How to Deploy to Production",
