# ~/.kimi-code/hooks/verify.sh — Stop hook body for Kimi Code CLI.
#
# Fires when the model is about to end its turn. Runs the project's test suite;
# on failure, exits 2 with the summary on stderr, which Kimi appends to context
# and the model keeps working. On success (or no detectable runner) exits 0.
#
# Register in config.toml:
#   [[hooks]]
#   event = "Stop"
#   command = "bash ~/.kimi-code/hooks/verify.sh"
#   timeout = 300
#
# Remember: hooks fail open. If this script crashes or times out the turn ends
# normally. It is a quality loop, not a security barrier — deny rules are that.
