When Slack API Failed His Agent, Codex Fell Back to Computer Use — and It Worked
Yuchenj_UW · x · 2026-09-16
Developer Yuchen Jin shares a telling anecdote: Slack's API is painfully slow and rate-limited, clearly not built for agents. He asked Codex/Astra to search a huge Slack channel; with his auth broken, the model skipped the API entirely and used computer use instead — scrolling through Slack quickly and finding exactly what was needed. "The era of AI operating computers is finally here," he writes, highlighting how legacy SaaS APIs are lagging behind the agent ecosystem.
