+description: "Outline wiki integration for knowledge management and documentation workflows. Use when Opencode needs to interact with Outline for: (1) Creating and editing documents, (2) Searching and retrieving knowledge base content, (3) Managing document collections and hierarchies, (4) Handling document sharing and permissions, (5) Collaborative features like comments. Triggers: 'Outline', 'wiki', 'knowledge base', 'documentation', 'team docs', 'document in Outline', 'search Outline', 'Outline collection'."

+# Outline Wiki Integration
+
+Outline is a team knowledge base and wiki platform. This skill provides guidance for Outline API operations and knowledge management workflows.
+
+## Core Capabilities
+
+### Document Operations
+
+- **Create**: Create new documents with markdown content
+- **Read**: Retrieve document content, metadata, and revisions
+- **Update**: Edit existing documents, update titles and content
+- **Delete**: Remove documents (with appropriate permissions)
+
+### Collection Management
+
+- **Organize**: Structure documents in collections and nested collections
+- **Hierarchies**: Create parent-child relationships
+- **Access Control**: Set permissions at collection level
+
+### Search and Discovery
+
+- **Full-text search**: Find documents by content
+- **Metadata filters**: Search by collection, author, date
+- **Advanced queries**: Combine multiple filters
+
+### Sharing and Permissions
+
+- **Public links**: Generate shareable document URLs
+- **Team access**: Manage member permissions
+- **Guest access**: Control external sharing
+
+### Collaboration
+
+- **Comments**: Add threaded discussions to documents
+- **Revisions**: Track document history and changes
+- **Notifications**: Stay updated on document activity
+
+## Workflows
+
+### Creating a New Document
+
+1. Determine target collection
+2. Create document with title and initial content
+3. Set appropriate permissions
+4. Share with relevant team members if needed
+
+### Searching Knowledge Base
+
+1. Formulate search query
+2. Apply relevant filters (collection, date, author)
+3. Review search results
+4. Retrieve full document content when needed
+
+### Organizing Documents
+
+1. Review existing collection structure
+2. Identify appropriate parent collection
+3. Create or update documents in hierarchy
+4. Update collection metadata if needed
+
+### Document Collaboration
+
+1. Add comments for feedback or discussion
+2. Track revision history for changes
+3. Notify stakeholders when needed
+4. Resolve comments when addressed
+
+## Integration Patterns
+
+### Knowledge Capture
+
+When capturing information from conversations or research:
+- Create document in appropriate collection
+- Use clear, descriptive titles
+- Structure content with headers for readability
+- Add tags for discoverability
+
+### Documentation Updates
+
+When updating existing documentation:
+- Retrieve current document revision
+- Make targeted, minimal changes
+- Add comments explaining significant updates
+- Share updates with relevant stakeholders
+
+### Knowledge Retrieval
+
+When searching for information:
+- Start with broad search terms
+- Refine with collection and metadata filters
+- Review multiple relevant documents
+- Cross-reference linked documents for context
+
+## Common Use Cases
+
+| Use Case | Recommended Approach |
+|----------|---------------------|
+| Project documentation | Create collection per project, organize by phase |
+| Team guidelines | Use dedicated collection, group by topic |
+| Meeting notes | Create documents with templates, tag by team |
+| Knowledge capture | Search before creating, link to related docs |
+| Onboarding resources | Create structured collection with step-by-step guides |
+
+## Best Practices
+
+- **Consistent naming**: Use clear, descriptive titles
+- **Logical organization**: Group related documents in collections
+- **Regular maintenance**: Review and update outdated content
+- **Access control**: Set appropriate permissions for sensitive content
+- **Searchability**: Use tags and metadata effectively
+- **Collaboration**: Use comments for discussions, not content changes
