Anthropic has introduced Claude Tag for Slack, enabling the model to act as a proactive colleague that joins discussions, handles tasks in sequence, posts results in threads, operates in ambient mode and schedules its own reminders. Internally the company now generates 65 percent of its code with the tool while administrators retain token caps to manage spending.
The system independently plans its daily workload and dispatches alerts to the appropriate colleagues while running without constant supervision.
To avoid runaway expenses, workspace admins set a ceiling on the number of tokens Claude may consume before the model begins declining further requests.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
Anthropic launched Claude Opus 5.5 on September 22, 2026 as the first model in its Claude 5.5 family, claiming it matches Claude Fable 5.1 performance while running 40% cheaper and 30% faster than Opus 5.
