feat(flint): add Flint integration with agent task tools, block, and docs by waleedlatif1 · Pull Request #5641 · simstudioai/sim

waleedlatif1 · 2026-07-13T19:07:50Z

Summary

Add Flint integration (Agent Tasks API): flint_create_task (prompt tasks), flint_generate_pages (template-based page generation, 1-10 pages), flint_get_task (status + created/modified/deleted pages)
Bearer API-key auth against https://app.tryflint.com/api/v1; items JSON parsed/validated at execution time so block references survive serialization
New Flint block with operation dropdown, conditional fields, advanced-mode publish/callback options, wand config for the pages JSON, and 8 BlockMeta templates + 3 skills
FlintIcon (monochrome, currentColor for bare/theme-safe rendering), registered in tool/block registries and icon mappings, generated docs page
No file upload/download endpoints exist in the Flint API, so no file-handling plumbing is needed

Manual Description

Flint is an AI website builder — this integration lets workflows drive its background agent over the Agent Tasks API (two endpoints: POST /agent/tasks, GET /agent/tasks/{taskId}).

To exercise it manually:

Drop the Flint block on the canvas and paste a Flint API key (ak_..., from Flint team settings).
Create Task: enter a Site ID and a prompt like "Add a new About page with a team section" — returns taskId with status running.
Generate Pages: enter the Site ID, a template page slug (e.g. /case-studies/template), and a JSON array of 1-10 {targetPageSlug, context} items (the wand can generate it) — returns a taskId.
Get Task: poll with the returned taskId until status is completed (exposes pagesCreated/pagesModified/pagesDeleted with preview/edit/published URLs) or failed (exposes errorMessage).
Advanced mode adds a Publish on Completion switch and a webhook Callback URL for both create operations.

Type of Change

New feature

PR Summary

Medium Risk
Workflows can trigger live site changes and optional auto-publish via a third-party API using stored API keys; scope is limited to a new integration following existing tool/block patterns with input validation.

Overview
Adds a Flint integration so workflows can drive Flint’s Agent Tasks API (Bearer API key against https://app.tryflint.com/api/v1).

Three new tools cover the task lifecycle: create task from a natural-language prompt, generate pages (1–10 items from a template slug, with JSON parse/validation at execution time), and get task (status plus created/modified/deleted page URLs). A new Flint canvas block wires those operations with conditional fields, advanced publish / callback options, and coercePublish so an explicit false is not dropped. Catalog surfaces get FlintIcon, block/tool registry entries, integrations.json, docs (flint.mdx), and BlockMeta templates/skills.

Greptile Summary

This PR adds a Flint integration for running and polling background agent tasks. The main changes are:

New Flint block with create, generate pages, and get task operations.
New Flint tools for Agent Tasks API requests and response shaping.
Flint icon, registry, integration metadata, and docs entries.
Runtime validation for generated page items.

Confidence Score: 5/5

This looks safe to merge.

No blocking issues found in the changed code.

Greptile Summary

This PR adds Flint as a new Sim integration. The main changes are:

New Flint block with create, generate pages, and get task operations.
New Flint tool configs for the Agent Tasks API.
Flint icon, registry entries, integration metadata, and docs page.
Runtime JSON parsing for generated page items.

Confidence Score: 4/5

The Flint publish mapping needs a fix before merging.

Registry, icon, API-key visibility, and JSON item handling follow the established integration patterns.
The block can omit an explicit publish opt-out before the request reaches Flint.
That can make live publishing depend on Flint's default instead of the user's switch value.

apps/sim/blocks/blocks/flint.ts

Security Review

The publish option can be omitted when a user explicitly turns publishing off, which may allow live Flint site changes if the API default publishes.

Important Files Changed

Filename	Overview
apps/sim/blocks/blocks/flint.ts	Adds the Flint block, UI fields, tool mapping, metadata templates, and skills; the publish mapping drops explicit false values.
apps/sim/tools/flint/create_task.ts	Adds the create task ToolConfig with bearer auth, POST body construction, and task-created output mapping.
apps/sim/tools/flint/generate_pages.ts	Adds the generate pages ToolConfig with item parsing, validation, and request body construction.
apps/sim/tools/flint/get_task.ts	Adds the task polling ToolConfig and normalizes returned page arrays into nullable page objects.
apps/sim/tools/flint/utils.ts	Adds shared Flint API URL, bearer headers, and user-only API key parameter metadata.
apps/sim/tools/registry.ts	Registers the three Flint tools under matching snake_case IDs.
apps/sim/blocks/registry-maps.ts	Registers the Flint block and metadata in the block registries.
apps/sim/components/icons.tsx	Adds the Sim Flint icon with currentColor fills.
apps/docs/components/icons.tsx	Adds the docs Flint icon with currentColor fills.
apps/docs/content/docs/en/integrations/flint.mdx	Adds the Flint integration documentation page.

Off publish switch still omits field
Medium Severity
coercePublish returns undefined when Publish on Completion was never toggled, so publish is omitted from the Flint request. The switch still renders off via Boolean(null/undefined), so the UI looks unpublished while Flint can apply its server default. Basic-mode runs never show the switch, so they always hit that omit path.
