# observe-first.sh — Claude Code Hook
# ============================================================================
# Event:    PreToolUse (Write, Edit)
# Purpose:  Reminds agents to call observe() or query() before writing to
#           memory directories (Mind/, Journal/, memory/).
# How:      Checks the file path of Write/Edit operations. If targeting a
#           memory directory, injects a system message reminder.
# Disable:  Delete this file from .claude/hooks/ — no other config needed.
# Part of:  fozikio — portable, no project-specific paths.
# ============================================================================
