Session Status

Reports current Claude Code session elapsed time.

Mechanism

A SessionStart hook writes $(date +%s) to ~/.claude/session-env/<session_id>/session-tracker. The session ID is stable across compaction, so the timestamp survives context resets. The hook outputs CLAUDE_SESSION_FILE=<path> — use that path in the command below.

UserPromptSubmit and Stop hooks append P <ts> / S <ts> lines to events.log in the same directory. Active vs idle time is derived from those events: any gap between a Stop and the next UserPromptSubmit longer than SESSION_IDLE_THRESHOLD_SECONDS (default 300) counts as idle.

Usage

Run this to get session elapsed time (replace $CLAUDE_SESSION_FILE with the path from the SessionStart hook output):

start=$(cat "$CLAUDE_SESSION_FILE" 2>/dev/null)
if [ -n "$start" ]; then
  now=$(date +%s)
  elapsed=$((now - start))

  # Idle: sum gaps between Stop and next UserPromptSubmit that exceed threshold.
  THRESHOLD="${SESSION_IDLE_THRESHOLD_SECONDS:-300}"
  EVENTS="$(dirname "$CLAUDE_SESSION_FILE")/events.log"
  idle=0
  if [ -f "$EVENTS" ]; then
    idle=$(awk -v th="$THRESHOLD" -v now="$now" '
      { kind=$1; ts=$2+0 }
      kind=="S" { last=ts; have=1; next }
      kind=="P" && have { g=ts-last; if (g>th) i+=g; have=0 }
      END { if (have) { g=now-last; if (g>th) i+=g } printf "%d", i+0 }
    ' "$EVENTS")
  fi
  [ "$idle" -gt "$elapsed" ] && idle="$elapsed"
  active=$((elapsed - idle))

  fmt() { h=$(( $1 / 3600 )); m=$(( ($1 % 3600) / 60 )); [ "$h" -gt 0 ] && printf '%dh %dm' "$h" "$m" || printf '%dm' "$m"; }
  started=$(date -r "$start" "+%H:%M" 2>/dev/null || date -d "@$start" "+%H:%M" 2>/dev/null)
  echo "Session: $(fmt "$elapsed") (active: $(fmt "$active"), idle: $(fmt "$idle"), started at ${started})"
else
  echo "Session file not found - hook may not be configured"
fi

Daily Total (additional)

After showing the live session, also report today's accumulated total by summing duration_seconds from $HOME/.claude/session-env/history.jsonl for entries whose start_ts falls on today's local date, and adding the current live elapsed:

HISTORY="$HOME/.claude/session-env/history.jsonl"
today_past=0
if [ -f "$HISTORY" ]; then
  today=$(date +%Y-%m-%d)
  today_past=$(jq -s --arg today "$today" '
    map(select((.start_ts | strflocaltime("%Y-%m-%d")) == $today))
    | map(.duration_seconds) | add // 0
  ' "$HISTORY")
fi
total_today=$((today_past + elapsed))
th=$((total_today / 3600))
tm=$(((total_today % 3600) / 60))
if [ $th -gt 0 ]; then
  echo "Today: ${th}h ${tm}m (across finished + current sessions)"
else
  echo "Today: ${tm}m (across finished + current sessions)"
fi

Current Issue (additional)

If the session is associated with an issue, include one extra line. Resolution order mirrors the SessionEnd hook:

1. "$(dirname "$CLAUDE_SESSION_FILE")/issue-tag" exists → Current issue: <KEY>.
2. Else, if cwd is a git repo and the current branch matches [A-Z][A-Z0-9_]+-[0-9]+ → Current issue: <KEY> (from branch).
3. Else, omit the line entirely.

TAG_FILE="$(dirname "$CLAUDE_SESSION_FILE")/issue-tag"
if [ -f "$TAG_FILE" ]; then
  issue=$(head -n1 "$TAG_FILE" | tr -d '[:space:]')
  [ -n "$issue" ] && echo "Current issue: $issue"
elif command -v git >/dev/null 2>&1; then
  br=$(git branch --show-current 2>/dev/null || true)
  m=$(printf '%s\n' "$br" | grep -oE '[A-Z][A-Z0-9_]+-[0-9]+' | head -n1 || true)
  [ -n "$m" ] && echo "Current issue: $m (from branch)"
fi

Output Format

Display to user:

Session: 2h 15m (active: 1h 50m, idle: 25m, started at 14:30)
Today: 5h 42m (across finished + current sessions)
Current issue: LIN-456

Idle threshold is configurable via the SESSION_IDLE_THRESHOLD_SECONDS env var (default 300 = 5 minutes).

If the current session file is missing, inform: session tracking hook not configured. If only the history file is missing, still show the live session and skip the Today line (or show it equal to the live elapsed).

To reset the live timer, tell the user they can use /session-tracker:reset-session or ask naturally. To see a full worklog, suggest /session-tracker:session-history.
