# Passive event recorder. Writes one JSON line per event to
|
|
# .cheat-cache/usage.jsonl in the project root. Never blocks (async fire-and-forget).
|
|
#
|
|
# Used by /cheat-status to compute:
|
|
# - "distance since last bump" (count of cheat-predict invocations after last_bump_at)
|
|
# - skill invocation frequency
|
|
# - tool failure patterns
|
|
#
|
|
# Usage: log-event.sh <event_type>
|
|
# <event_type> ∈ {tool_use, user_prompt, session_start, session_end}
|
|
#
|
|
# Reads from stdin: Claude Code's hook payload JSON
|
|
# Output: appends one line to .cheat-cache/usage.jsonl
