Greptile Summary

This PR adds a Google Chat integration with OAuth, enabling two operations: Send Message (post to a space with optional thread key) and List Spaces (enumerate spaces the user is a member of). The OAuth provider is correctly registered in auth.ts and oauth.ts under the existing Google provider group, tools are registered in both the tool and block registries, and scope descriptions for the two new Chat scopes are added to the OAuth required modal.

Tools, block config, icon, and documentation all follow established patterns for Google integrations
OAuth registration correctly reuses GOOGLE_CLIENT_ID/GOOGLE_CLIENT_SECRET, consistent with other Google services
pageToken is fully implemented in list_spaces.ts (correctly appended to the API request URL) but is not wired through the block config — inputs, subBlocks, and the params function for list_spaces all omit it, making pagination non-functional at the block level despite the block advertising nextPageToken as an output

Confidence Score: 4/5

Safe to merge after fixing pageToken wiring — current code silently drops pagination tokens making list_spaces pagination non-functional

One P1 defect: the block config for list_spaces omits pageToken from inputs, subBlocks, and the params function, so the block's own nextPageToken output can never be used for subsequent page fetches. All other integration components (tools, OAuth registration, icon, docs) are correctly implemented and follow established patterns.

pageToken not wired through for list_spaces pagination

The pageToken parameter is defined in GoogleChatListSpacesParams and correctly forwarded to the Google API in list_spaces.ts, but it is silently dropped at the block level — it is absent from inputs, subBlocks, and the params return for the list_spaces case.

The block already outputs nextPageToken, but there is no corresponding input to feed that token back into a subsequent call, making pagination non-functional through the block.

Add pageToken to the returned params:

Suggested change

case 'list_spaces':

return {

oauthCredential,

pageSize: rest.pageSize ? Number(rest.pageSize) : undefined,

filter: rest.filter,

}

case 'list_spaces':

return {

oauthCredential,

pageSize: rest.pageSize ? Number(rest.pageSize) : undefined,

pageToken: rest.pageToken,

filter: rest.filter,

}

Also add pageToken to the inputs object:

pageToken: { type: 'string', description: 'Token for fetching the next page of results' },

And add a subBlock (in advanced mode) so users can wire a previous call's nextPageToken output into this field:

{ id: 'pageToken', title: 'Page Token', type: 'short-input', placeholder: 'Token from previous list_spaces call', condition: { field: 'operation', value: 'list_spaces' }, mode: 'advanced', },
