Skill: Sync mkdocs.yml nav

Parent: AGENTS.md

Keep the nav: section in mkdocs.yml in sync with the files that actually exist under doc/. Run this whenever a new doc is added and needs to appear on https://exelearning.github.io/exelearning/.

---

0. Before you start

Read these two sources in full:

1. mkdocs.yml — current nav and site config.
2. All .md files under doc/ — use Glob with doc/**/*.md.

Do not skip any file. The goal is a nav that references every .md file exactly once.

---

1. Identify gaps

List every .md path returned by the glob. Normalize paths to forward slashes and strip the doc/ prefix (MkDocs paths are relative to docs_dir: doc).

Compare with every path already referenced under nav: in mkdocs.yml.

Report which files are missing from the nav and which nav entries point to files that no longer exist (stale entries). Both must be fixed.

---

2. Assign each doc to a section

Use the table below to decide where each file belongs. When in doubt, read the first two lines of the file for its title and description.

Path prefix / filename	Nav section
index.md	Top level — always first
overview.md	Top level
install.md	Top level
profile-avatars.md	Top level (end users)
deployment.md	Top level
high-availability.md	Top level
deploy/README.md	Top level — label "Deploy: Sample Configs"
architecture.md	Top level — label "Architecture"
conventions.md	Top level — label "Conventions"
development/*.md	Development section
contentv3-format.md	File Formats section — label "Legacy ELP Format"
elpx-format.md	File Formats section — label "ELPX Format" (subsection root)
elpx-format/*.md	File Formats › ELPX Format subsection
elpx-format/idevices/*.md	File Formats › ELPX Format › iDevices sub-subsection
elpx-format/examples/*.md	File Formats › ELPX Format › Examples sub-subsection

Ordering within each section

Top level (in this order):

1. Home (index.md)
2. Overview (overview.md)
3. Install (install.md)
4. Profile Avatars (profile-avatars.md)
5. Deployment (deployment.md)
6. High Availability (high-availability.md)
7. Deploy: Sample Configs (deploy/README.md)
8. Architecture (architecture.md)
9. Conventions (conventions.md)

Development (alphabetical by label, except Environment first): Environment → Version Control → Contributing → Testing → Internationalization → Real Time → Embedding → Profiling → Customization → Styles → Installers → REST API → Authentication

File Formats (Legacy ELP first, then ELPX):

1. Legacy ELP Format (contentv3-format.md)
2. ELPX Format (elpx-format.md) — then subsections in this order:
   • Container & XML group: Container → content.xml → IDs → Metadata → Pages & Blocks
   • iDevices subsection: Catalog → Patterns → config.xml → Snippets
   • Resources group: Themes → Libraries → Assets → Screenshot
   • Pipelines group: Tracking → Export Pipeline → Import Pipeline → Validation
   • AI Generation
   • Examples subsection: Minimal → Multi-page → Full Package Tree

If a new file appears that doesn't match any entry above, add it to the most logical section and note your choice as a comment in your response.

3. Write the updated mkdocs.yml

Preserve everything outside the nav: block exactly as-is (theme, plugins, markdown_extensions, extra, validation, etc.). Only replace the nav: block.

Use 2-space indentation inside nav: (MkDocs convention). Labels must be human-readable title case.

Target structure (expand as needed to include every file):

nav:
  - Home: index.md
  - Overview: overview.md
  - Install: install.md
  - Profile Avatars: profile-avatars.md
  - Deployment: deployment.md
  - High Availability: high-availability.md
  - Deploy\: Sample Configs: deploy/README.md
  - Architecture: architecture.md
  - Conventions: conventions.md
  - Development:
      - Environment: development/environment.md
      - Version Control: development/version-control.md
      - Contributing: development/contributing.md
      - Testing: development/testing.md
      - Internationalization: development/internationalization.md
      - Real Time: development/real-time.md

      - Styles: development/styles.md
      - Installers: development/installers.md
      - REST API: development/rest-api.md
      - Authentication: development/authentication.md
  - File Formats:
      - Legacy ELP Format: contentv3-format.md
      - ELPX Format:
          - Overview: elpx-format.md
          - Container: elpx-format/container.md
          - content.xml: elpx-format/content-xml.md
          - IDs: elpx-format/ids.md
          - Metadata: elpx-format/metadata.md
          - Pages & Blocks: elpx-format/pages-blocks.md
          - iDevices:
              - Catalog: elpx-format/idevices/catalog.md
              - Patterns: elpx-format/idevices/patterns.md
              - config.xml: elpx-format/idevices/config-xml.md
              - Snippets: elpx-format/idevices/snippets.md
          - Themes: elpx-format/themes.md
          - Libraries: elpx-format/libraries.md
          - Assets: elpx-format/assets.md
          - Screenshot: elpx-format/screenshot.md
          - Tracking: elpx-format/tracking-emission.md
          - Export Pipeline: elpx-format/export-pipeline.md
          - Import Pipeline: elpx-format/import-pipeline.md
          - Validation: elpx-format/validation.md
          - AI Generation: elpx-format/ai-generation.md
          - Examples:
              - Minimal content.xml: elpx-format/examples/minimal-content-xml.md
              - Multi-page content.xml: elpx-format/examples/multi-page-content-xml.md
              - Full Package Tree: elpx-format/examples/full-package-tree.md

Important: The colon in Deploy: Sample Configs must be escaped as \: inside a YAML mapping key. Alternatively, quote the key: "Deploy: Sample Configs". Either is correct YAML; prefer the quoted form for readability.

After writing the file, re-read it and confirm the YAML is valid (no duplicate keys, consistent indentation).

4. Report back

Tell the user:

1. Which files were added to the nav (list them).
2. Which entries were removed as stale (list them, if any).
3. Which files, if any, you placed in a section not listed in the table above, and why.
4. Any file you skipped and the reason (e.g., it is a doc/style.css or non-Markdown asset — those should never appear in the nav).

Do not modify any file other than mkdocs.yml.
