+# Triage labels
+
+These labels represent workflow roles rather than subject areas.
+
+| Label | Meaning |
+| --- | --- |
+| `needs-triage` | The request has not yet been classified or evaluated. |
+| `needs-info` | More information or a human decision is required before work can proceed. |
+| `ready-for-agent` | The work is sufficiently specified, unblocked, and suitable for an agent. |
+| `ready-for-human` | The work requires human review, approval, or an action only a human can perform. |
+| `wontfix` | The request has been deliberately declined or will not be implemented. |
+
+Use only the labels that describe the issue's current workflow state.
+
+Remove obsolete workflow labels when the state changes. For example, remove
+`needs-info` when the missing information has been supplied.
+
+Subject-area labels may be added separately, but they must not replace these
+workflow roles.
