+# set-wezterm-profile.sh — SessionStart hook: emit WezTerm theme escape sequence
+#
+# Derives the profile name from CLAUDE_CONFIG_DIR (e.g. ~/.claude-octopus → octopus)
+# and emits a SetUserVar escape sequence so WezTerm fires its user-var-changed
+# event and applies the matching theme from wezterm.lua.
+#
+# Hook subprocesses have no controlling terminal, so the escape sequence is
+# written to the pts device found by walking up the process tree.
+# Safe in non-WezTerm terminals (escape sequence is silently ignored).
+#
+# Usage (settings.json):
+#   "SessionStart": [{ "hooks": [{ "type": "command",
+#     "command": "~/.claude/hooks/set-wezterm-profile.sh" }] }]
