# SessionStart(startup|resume) hook: title the session "<host>-<project>"
# (e.g. "ratio-rulesets", "velox-work") so remote sessions are identifiable
# in the claude.ai/code and mobile session lists instead of auto-generated
# names.
#
# Project = basename of the git toplevel when cwd is inside a repo (a session
# started in a subdirectory still names the project), else basename of cwd.
#
# Only fires when the session has no title yet: a /rename, an earlier run, or
# any other titling must not be clobbered on resume. The harness ignores
# sessionTitle on clear/compact sources, so the settings matcher restricts to
# startup|resume.
#
# Wire in settings.json:
#
# "SessionStart": [
# { "matcher": "startup|resume",
# "hooks": [ { "type": "command",
# "command": "~/.claude/hooks/session-title.sh" } ] }
# ]
