Update API Documentation

This skill guides you through updating the API reference documentation from the production OpenAPI specification.

Overview

The API documentation is generated from an OpenAPI spec using docusaurus-plugin-openapi-docs. The workflow involves:

1. Downloading the latest openapi.json from production
2. Replacing the local spec file
3. Regenerating the API documentation pages

File Locations

Purpose	Path
OpenAPI spec (source)	docs/docs/reference/openapi.json
Generated API docs	docs/docs/reference/api/*.api.mdx
Generated sidebar	docs/docs/reference/api/sidebar.ts
Docusaurus config	docs/docusaurus.config.ts

Steps

1. Run the update script

The wrapper script at docs/scripts/update-api-docs.sh downloads the OpenAPI spec, replaces the local file, and regenerates the docs in one step.

cd docs

# Default — fetch from production (live cloud API)
pnpm update-api-docs

# Explicit live cloud API
pnpm update-api-docs:live

# From a locally running API (http://localhost/api/openapi.json)
pnpm update-api-docs:local

# From an explicit local file
pnpm update-api-docs:file /path/to/openapi.json

The script writes the spec to docs/docs/reference/openapi.json and then runs npm run clean-api-docs -- agenta followed by npm run gen-api-docs -- agenta. The agenta argument refers to the OpenAPI config ID defined in docusaurus.config.ts.

2. Install dependencies (if needed)

If this is a fresh clone or dependencies haven’t been installed:

cd docs
npm install

This generates:

• Individual .api.mdx files for each endpoint
• .tag.mdx files for API categories
• sidebar.ts for navigation

5. Verify the changes

Optionally, start the dev server to preview:

cd docs
npm run start

Then visit http://localhost:5000/docs/reference/api to verify the API docs render correctly.

Commit Guidelines

When committing these changes:

1. First commit - API docs update:

   docs(api): update OpenAPI spec from production

2. Include all changed files:

   • docs/docs/reference/openapi.json
   • docs/docs/reference/api/*.api.mdx
   • docs/docs/reference/api/*.tag.mdx
   • docs/docs/reference/api/sidebar.ts

Troubleshooting

”missing required argument ‘id’” error

The clean and generate commands require the config ID. Use:

npm run clean-api-docs -- agenta
npm run gen-api-docs -- agenta

“docusaurus: not found” error

Run npm install in the docs/ directory first.

Deprecation warning about onBrokenMarkdownLinks

This is a known warning and can be safely ignored. It will be addressed in a future Docusaurus v4 migration.
