Description

closes CON-4252

This pull request adds comprehensive documentation for integrating and automating project management workflows with Linear and Notion using the Continue CLI and their respective MCPs. It introduces two new step-by-step guides—one for Linear and one for Notion—covering setup, example workflows, security best practices, and advanced integrations. The guides are now referenced in the documentation index and overview.

New Integration Guides:

• Linear MCP + Continue Guide:

  • Provides a detailed cookbook (linear-continue-cookbook.mdx) for automating issue creation, sprint planning, and project management in Linear using natural language prompts and the Continue CLI.
  • Covers both quick-start (pre-built agent) and manual setup, with example prompts, advanced multi-tool workflows, and security recommendations.

• Notion MCP + Continue Guide:

  • Adds a full cookbook (notion-continue-cookbook.mdx) for automating documentation, task management, and project workflows in Notion via Continue CLI and MCP.
  • Includes setup instructions, quick-start and manual options, example prompts, advanced workflows, and security best practices.

Documentation Index Updates:

• Adds both new guides to the documentation JSON index for discoverability.
• Updates the overview page to include links and descriptions for the new Linear and Notion cookbooks.
