# Builds a structured JSON notification payload for warp://cli-agent.

# Usage: source this file, then call build_payload with event-specific fields.
5+
#
6+
# Example:
7+
# source "$(dirname "${BASH_SOURCE[0]}")/build-payload.sh"
8+
# BODY=$(build_payload "$INPUT" "stop" \
9+
# --arg query "$QUERY" \
10+
# --arg response "$RESPONSE" \
11+
# --arg transcript_path "$TRANSCRIPT_PATH")
12+
#
13+
# The function extracts common fields (session_id, cwd, project) from the
14+
# hook's stdin JSON (passed as $1), then merges any extra jq args you pass.
