 Load and follow strictly:
-- $HOME/.claude/agents/status-reporter.md
+- `$HOME/.claude/agents/status-reporter.md`
 
 Produce the full PROJECT STATUS report for the current working directory.
 
+## Fallback when agent file missing
+
+If `$HOME/.claude/agents/status-reporter.md` is unreachable (deleted, permission denied, broken symlink):
+
+1. Emit: `Status agent missing — restore ~/.claude/agents/status-reporter.md.`
+2. STOP. Do not improvise a manual report — partial snapshots mislead.
