 Inspect active loop state, progress, and failure signals.
 
+This slash command can only run after the current session dequeues it. If you
+need to inspect a wedged or sibling session, run the packaged CLI from another
+terminal:
+
+```bash
+npx --package ecc-universal ecc loop-status --json
+```
+
+The CLI scans local Claude transcript JSONL files under
+`~/.claude/projects/**` and reports stale `ScheduleWakeup` calls or `Bash`
+tool calls that have no matching `tool_result`.

+## Cross-Session CLI
+
+- `ecc loop-status --json` emits machine-readable status for recent local
+  Claude transcripts.
+- `ecc loop-status --transcript <session.jsonl>` inspects one transcript
+  directly.
+- `ecc loop-status --bash-timeout-seconds 1800` adjusts the stale Bash
+  threshold.
+
 ## Watch Mode
 
 When `--watch` is present, refresh status periodically and surface state changes.
