Integration documentation generator

generate-docs.ts compiles the per-service integration pages under apps/docs/content/docs/en/integrations/ from the block/tool/trigger registry in apps/sim. The ontology it encodes: everything is a block, and an integration is one block that has Actions and, optionally, a Trigger.

Golden rule: the generated .mdx files are derived artifacts, not the source of truth. Do not hand-edit them — your changes are overwritten on the next run. The only editable region is the MANUAL-CONTENT block (see below). To change what a page says, edit the TypeScript in apps/sim and regenerate.

Where an integration lives canonically

For a service like Gmail, three TS sources define it:

Source	What it is	What it feeds in the page
apps/sim/blocks/blocks/<service>.ts	The block: type, name, category (tools for integrations), bgColor, config sub-blocks, tools.access (which actions it exposes), an optional triggers capability, outputs	Header / BlockInfoCard, Usage Instructions, and which actions + trigger appear
apps/sim/tools/<service>/*.ts	Each action's params + outputs	Every ### <action> → #### Input / #### Output under ## Actions
apps/sim/triggers/<provider>/	The trigger's config fields + outputs	The ## Triggers section
apps/sim/components/icons.tsx	The brand glyph	The page icon

The block references actions by id in tools.access; the generator looks each one up in apps/sim/tools/.

What the generator does

Run with cd apps/sim && bun run generate-docs (or bun run scripts/generate-docs.ts from the repo root). One pass (generateAllBlockDocs):

1. Copies icons apps/sim/components/icons.tsx → apps/docs/components/icons.tsx and builds apps/docs/components/ui/icon-mapping.ts.
2. Block pass — for each integration block (category: 'tools', plus the memory / knowledge / table exceptions), writes integrations/<service>.mdx: BlockInfoCard + Usage Instructions + ## Actions.
3. Trigger pass (generateAllTriggerDocs) — reads apps/sim/triggers/<provider>/ and appends a ## Triggers section to that service's page, or writes a standalone page for trigger-only services.
4. Writes integrations/meta.json and regenerates the landing page's integrations.json.

Hand-written pages it never touches

Core block pages (blocks/*), the native trigger pages (triggers/{start,schedule,webhook,rss,table}), the integrations overview (integrations/index.mdx), and the service-account pages are fully hand-written. The generator skips them via HANDWRITTEN_INTEGRATION_DOCS, HANDWRITTEN_TRIGGER_DOCS, and SKIP_TRIGGER_PROVIDERS. Add a page name to those sets if you hand-author a page the generator would otherwise produce.

Manual content (the one editable region)

Each generated page may carry hand-written prose inside marker comments. The generator preserves anything between the markers and overwrites everything else, so this survives every regeneration:

{/* MANUAL-CONTENT-START:intro */}
[AgentMail](https://agentmail.to/) is an API-first email platform…
{/* MANUAL-CONTENT-END */}

Supported section names: intro (after the BlockInfoCard — the most common), usage, configuration, outputs, notes. The merge is by marker name (extractManualContent + mergeWithManualContent), so a section is re-inserted at the matching spot in the freshly generated structure.

If you move the output folder, reseed manual content from the old location first — the generator only preserves markers it finds in the existing output file, so a fresh folder starts with none.

Practical: to change…

• An action's params/outputs, a trigger, or to add a service → edit apps/sim/{blocks,tools,triggers} and re-run the generator.
• A page's prose intro → edit its MANUAL-CONTENT:intro block directly; it survives regen.
• The overview / service-account / core-block / native-trigger pages → hand-edit freely.

Gotchas

• Never hand-edit apps/docs/components/icons.tsx — step 1 overwrites it from the sim app. Components that need an icon the sim app lacks should define it locally or use @sim/emcn/icons (see components/workflow-preview/block-icons.tsx).
• The generator is the source of truth for integrations/ and its meta.json; manual edits there are transient.

CI

The generator runs in CI on pushes to the main branch and commits the regenerated docs back. Keep block/tool/trigger metadata accurate in apps/sim and the docs follow.
