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/Stop and PreToolUse/PostToolUse hooks append events to events.log: P <ts> (prompt), T <ts> <tool> / D <ts> <tool> (tool start/done), S <ts> (stop). Active (working) time is computed additively by the shared awk that SessionStart deploys to $HOME/.claude/session-env/active-time.awk: each prompt → stop bracket counts in full, plus up to grace seconds of reading after each Stop (SESSION_IDLE_THRESHOLD_SECONDS, default 120). A session parked while you work elsewhere stops accruing after the grace, so the number reflects real attention rather than wall-clock. Wall-clock elapsed is reported as secondary context.

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=$((now - start))                       # wall-clock (secondary)
  grace="${SESSION_IDLE_THRESHOLD_SECONDS:-120}"
  EVENTS="$(dirname "$CLAUDE_SESSION_FILE")/events.log"
  AWKLIB="$HOME/.claude/session-env/active-time.awk"

  active="$elapsed"                              # fallback when awk/events absent
  if [ -f "$EVENTS" ] && [ -f "$AWKLIB" ]; then
    active=$(awk -v grace="$grace" -v t_end="$now" -f "$AWKLIB" "$EVENTS")
    case "$active" in ''|*[!0-9]*) active="$elapsed" ;; esac
  fi
  [ "$active" -gt "$elapsed" ] && active="$elapsed"
  idle=$((elapsed - active))

  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 "Trabalho: $(fmt "$active") · sessão aberta há $(fmt "$elapsed") (idle $(fmt "$idle"), desde ${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 active (working) seconds from $HOME/.claude/session-env/history.jsonl for entries whose start_ts falls on today's local date, and adding the current live active time:

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")) == $today))
    | map(.active_seconds // 0) | add // 0
  ' "$HISTORY")
fi
total_today=$((today_past + active))
th=$((total_today / 3600))
tm=$(((total_today % 3600) / 60))
if [ $th -gt 0 ]; then
  echo "Trabalho hoje: ${th}h ${tm}m (sessões concluídas + atual)"
else
  echo "Trabalho hoje: ${tm}m (sessões concluídas + atual)"
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:

Trabalho: 1h 50m · sessão aberta há 2h 15m (idle 25m, desde 14:30)
Trabalho hoje: 5h 42m (sessões concluídas + atual)
Current issue: LIN-456

The reading grace after each Stop is configurable via SESSION_IDLE_THRESHOLD_SECONDS (default 120 = 2 minutes). Active time is the headline; wall-clock ("aberta há…") is shown as context only.

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 Trabalho hoje line (or show it equal to the live active).

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.
