-# Desktop Command Center — CLI Agent Pre-flight Check
+# DifferentWire Standard Preflight Hook
 # =============================================================================
 # Runs on SessionStart. Blocks the session (exit 2) if required coordination
-# services are unavailable. Auto-starts the Dolt SSH tunnel if it's down.
+# services are unavailable. ALL checks are hard blocks.
 #
 # Required services:
-#   1. Dolt SSH tunnel (localhost → Hetzner:3307) — for Beads task tracking
-#   2. MCP Agent Mail (getunfocused.app/mcp/) — for multi-agent coordination
-#
-# Zombie port detection:
-#   If a previous session's SSH tunnel died without closing its socket,
-#   the port stays LISTENING with a dead PID. This hook detects that and
-#   falls back to alternate ports (3308, 3309).
+#   1. Citadel API — task management (HARD BLOCK)
+#   2. Agent Mail  — multi-agent coordination (HARD BLOCK)
 #
 # Exit codes:
-#   0 = all checks passed, session may proceed
-#   2 = BLOCKING — required service unavailable, session must not start
+#   0 = all checks passed
+#   2 = BLOCKING — required service unavailable
+#
+# Projects copy this to .claude/hooks/preflight.sh and customize PROJECT_DIR.
