Carbon Progress bar
Documents determinate and indeterminate progress bars, percentage or ratio helper text, active/success/error states, labels close to the bar, region busy relationships, and guidance to use loading or skeleton alternatives when progress is not measurable or the load is brief.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Agent progress trace | Choose agent progress trace when an agent or automation run has started and users need live status across multiple steps or tools. | The trace belongs to one run ID, reviewed plan version, objective, actor, start time, current state, and final state. | Supports the distinction between measurable progress indicators and richer trace states. |
| Progress bar | Choose progress bar when the system can report a meaningful value toward a bounded operation. | The progress bar appears only after the operation starts and is scoped to the affected file, job, card, dialog, or page region. | Carbon supports progress bars for measurable system operations, labels, helper values, determinate and indeterminate modes, active/success/error states, region busy semantics, and alternatives. |
