Pre-merge checks

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title 'Update index.md' is vague and generic, using a non-descriptive verb without conveying the meaningful change (adding documentation navigation entry).	Consider a more specific title like 'Add model-support page to documentation navigation' to clearly communicate the primary change.

Create the missing markdown file docs/about/model-support.md before merging.

The toctree entry about/model-support references a file that does not exist in the repository. The file docs/about/model-support.md must be created to complete this documentation update and prevent build failures.

🤖 Prompt for AI Agents

In docs/index.md around line 174 the toctree references "about/model-support"
but the file docs/about/model-support.md is missing; create
docs/about/model-support.md (matching the toctree path) and add the appropriate
markdown content or a placeholder with a title (e.g., "# Model Support") and any
required front-matter or section headings, commit the new file, and ensure the
path and filename match the toctree entry exactly so the docs build succeeds.
