feat(slack_app): request files:read scope so the bot can download attachments - #73568
Merged
Conversation
…achments Without files:read, Slack answers the url_private download with an HTTP 200 HTML interstitial instead of the file bytes. The attachment download path rejects that HTML and skips the file, so image and file attachments never reach the agent. Add files:read to SlackIntegrationScopeInReview so it is requested in DEV and local DEBUG installs (where the Slack app manifest can list in-review scopes), without tripping invalid_scope on US/EU Cloud until Slack approves it.

Problem
Mentioning the bot with an image or file attached fails: it replies that the attachment "failed to download from Slack." The install never requests
files:read, so the bot token can't read files. Slack returns an HTML interstitial instead of the bytes, the download path rejects it, and the attachment is skipped.Changes
Add
files:readtoSlackIntegrationScopeInReview(infrontend/src/types.ts) and regenerate the schema. In-review scopes are only requested in DEV/DEBUG, so this avoidsinvalid_scopeon Cloud until Slack approves the public app.Note
Also requires adding
files:readto the DEV Slack app manifest and reconnecting the integration to grant it.🤖 Agent context
Autonomy: Human-driven (agent-assisted)
Vojta reported the bug and asked me (Claude) to investigate and open this PR.
