Summary

Adds a CaptureKit integration: tools, block, icon and generated docs page. I work on CaptureKit, so this PR comes from the CaptureKit team.

Capture any web page as a PNG, JPEG, WebP image or a PDF, by viewport, full page or CSS selector on 17+ emulated devices; extract a page's metadata, links and Markdown; fetch raw HTML; and get an AI summary of what a website offers.

Operations:

Take Screenshot (capturekit_screenshot): Capture a public web page as a PNG, JPEG, WebP image or a PDF, by viewport, full page or CSS selector, and store it as a file.
Extract Content (capturekit_extract_content): Render a web page and get its title, description, favicon, Open Graph image, internal, external and social links, and optionally its Markdown.
Fetch HTML (capturekit_fetch_html): Fetch the raw HTML of a public page over plain HTTP, without a browser.
Analyze Website (capturekit_analyze_website): Read a website and get an AI summary of its value proposition, business type, key features, categories, use cases, audience and contact details.

Credentials are a CaptureKit API key on the block (AuthMode.ApiKey), sent as the x-api-key header. Every tool is an external ToolConfig.request against the CaptureKit API.

Product update (if relevant)

Marketing, compliance and research teams can archive pages, track competitor pages, and turn websites into clean input for agents. The block appears in the integrations catalog with 7 templates and grounded skills; the docs page is apps/docs/content/docs/integrations/capturekit.mdx.

Type of Change

Bug fix
New feature
Breaking change
Documentation
Other: ___________

Testing

Outputs follow the documented OpenAPI response schemas, and every tool was run against the live CaptureKit API through its request and transformResponse to confirm the mapped outputs; fields that the API documents as nullable are optional outputs.
Local gate on this branch: bun run lint, bun run type-check, bun run check:audits (all 62 audits), bun run apps/sim/scripts/check-block-registry.ts origin/staging, bun run apps/sim/scripts/check-canvas-sentences.ts --block=capturekit, and the existing blocks and tools/request-transport Vitest suites all pass.
Regenerated artifacts are committed: tool metadata, docs, block successors and the docs manifest.
No new unit tests, following the repo's testing guidance; the live run above is the end-to-end check.

          feat(capturekit): add CaptureKit integration

a4961af

Add a CaptureKit block for web page capture and content:
- Take a screenshot of a page as PNG, JPEG, WebP or PDF, full page or by
  CSS selector, on 17+ emulated devices, stored as a file
- Extract a page's metadata, internal, external and social links, and its
  Markdown
- Fetch a page's raw HTML without a browser
- Get an AI summary of what a website offers, its audience and contacts

Outputs follow the documented OpenAPI schemas and were checked against live
responses. Credentials are a CaptureKit API key sent in the x-api-key header.

Confidence Score: 4/5

[Medium impact] The changes affect workflows that choose to use the new CaptureKit integration.

No blocking behavior defect was established, but the two explicit repository requirements must be satisfied before merging.

Findings

Helpers live apart from caller ▶
Public icons lack required docs ▶

Summary

Adds CaptureKit with four API-key-backed operations:

Sim workflows can add CaptureKit and choose one of its four page actions.
CaptureKit returns a page screenshot or PDF as a workflow file.
CaptureKit turns rendered page details into separate workflow outputs.
CaptureKit returns raw page HTML for workflow steps.
CaptureKit turns a website into a summary and structured findings.

Two repository requirements remain: keep single-consumer helpers beside their caller and document the new exported icon functions.

Helpers live apart from caller

Both exported helpers in utils.ts are used only by extract_content.ts. The repository requires helpers with one consumer to stay inline. Move both functions into extract_content.ts and remove this extra module before merging.

Fixed in 7c1ebb8. Both helpers moved into extract_content.ts, their only consumer, and tools/capturekit/utils.ts is removed.

Public icons lack required docs

The new CaptureKitIcon exports here and in apps/docs/components/icons.tsx lack TSDoc. The repository requires TSDoc on exported APIs. Add a short declaration comment above both functions before merging.

          fix(capturekit): address review feedback

7c1ebb8

- Keep the two response mappers in extract_content.ts, their only caller
- Document the CaptureKitIcon export
- Read the operation from the mapper context so agent tools coerce the
  screenshot's numeric inputs too
