description: "Session clock-time AND token/cost analyzer. Reads the foundry plugin's timings.jsonl and invocations.jsonl logs (written by task-log.js) for wall-time, plus Claude Code transcripts (~/.claude/projects/**, main-loop + subagent files) for token usage and USD cost, and merges both into one per-session and per-skill report — local-tool vs subagent-spawn vs Skill vs AskUserQuestion idle vs main-loop reasoning residual time, and main-loop vs subagent spend by model tier. Useful for answering \"why did /oss:resolve run 30 minutes?\", \"what did this session cost?\", or \"which skill burns the most tokens?\". Pure log/transcript read — no instrumentation, no skill edits, no LLM calls. TRIGGER when: user asks where wall-clock time OR tokens/cost go during a skill/session, why a skill is slow or expensive, what dominates total runtime or spend, or wants a per-skill rollup over a recent window; phrases: \"where does time go\", \"why so slow\", \"what did this cost\", \"token spend\", \"why so expensive\", \"profile last session\", \"clock breakdown\", \"session timing\", \"which skill burns tokens\". SKIP: per-line Python perf (use foundry:perf-optimizer); known failure or hang (use /foundry:investigate); a real billing statement (prices are public list rates, not effective plan rates)."

<objective>

Bucket session **clock time** from `~/.claude/logs/{timings,invocations}.jsonl` into:

1. **Local tools** — Bash/Read/Edit/Write/Grep/Glob and other main-process tools 2. **Agent / subagent spawns** — Task/Agent calls (sync + background) 3. **Skill** — `tool=Skill` wall durations 4. **AskUserQuestion idle** — human-wait, separate column, excluded from compute total 5. **Main-loop reasoning (residual)** — session wall minus buckets above

...and bucket session **tokens/cost** from Claude Code transcripts (`~/.claude/projects/**`, main-loop + subagent files) into:

6. **Sessions ranked by cost** (window mode) — main $ vs subagent $ vs total $ per session, plus a per-command rollup; or **one session's deep-dive** (`--session-id`) — cost by main/sidechain × model tier, agent roster, top cache-rebuild calls, cold-start share

Outputs a markdown report at `.reports/profile/<UTC-timestamp>/report.md` plus a `.temp/output-profile-...md` copy: per-session clock table, per-skill clock rollup, top-N longest single calls, plus a `## Tokens & cost` section scoped to the same window / `--session-id`.

NOT for: per-line Python perf (use `foundry:perf-optimizer`); known failure diagnosis (use `/foundry:investigate`); a real billing statement (prices are public list rates, not effective plan rates).

</objective>

<inputs>

• **`--since DURATION`** (default `24h`) — window: `NNs|NNm|NNh|NNd`
• **`--session-id ID`** — optional; restrict to one session
• **`--top-n N`** (default `5`) — slowest single calls to list

If $ARGUMENTS empty, default window is 24h.

</inputs>

<workflow>

**Task tracking**: TaskCreate two tasks up front — 1 "Run analyzers + render report" (Steps 1–3), 2 "Step 4b: Print report header" (Step 4). Mark each `in_progress` before its first tool call; 1 completed once `report.md` exists, 2 completed right after the header and path are printed, before the executive summary.

Step 1: Parse args + create run dir

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
# timeout: 5000
SINCE="24h"
SESSION_ID=""
TOP_N="5"
for tok in $ARGUMENTS; do
  case "$tok" in
    --since=*)      SINCE="${tok#--since=}" ;;
    --since)        next_is_since=1 ;;
    --session-id=*) SESSION_ID="${tok#--session-id=}" ;;
    --top-n=*)      TOP_N="${tok#--top-n=}" ;;
    *)
      if [ "${next_is_since:-0}" = "1" ]; then SINCE="$tok"; next_is_since=0; fi
      ;;
  esac
done
STAMP="$(date -u +%Y-%m-%dT%H-%M-%SZ)"
REPORT_DIR=".reports/profile/$STAMP"
mkdir -p "$REPORT_DIR"
{
  echo "REPORT_DIR=$REPORT_DIR"
  echo "SINCE=$SINCE"
  echo "SESSION_ID=$SESSION_ID"
  echo "TOP_N=$TOP_N"
} | tee "${TMPDIR:-/tmp}/foundry-profile-state-${CSID}"

Values persisted to `${TMPDIR:-/tmp}/foundry-profile-state-${CSID}`; Steps 2–3 re-source it (bash state does not persist across Bash calls, and `REPORT_DIR` carries a per-shell timestamp that cannot be re-derived).

Step 2: Run analyzers — clock time, then tokens/cost

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
# timeout: 60000
. "${TMPDIR:-/tmp}/foundry-profile-state-${CSID}" 2>/dev/null   # reload REPORT_DIR/SINCE/SESSION_ID/TOP_N (fresh shell)
OPT_SID=""
[ -n "$SESSION_ID" ] && OPT_SID="--session-id $SESSION_ID"
python "${CLAUDE_PLUGIN_ROOT:-plugins/cc_foundry}/bin/timing_analyzer.py" \
    --since "$SINCE" \
    --top-n "$TOP_N" \
    --output "$REPORT_DIR/report.md" \
    $OPT_SID 2>"$REPORT_DIR/warnings.log"
echo "time_exit=$?"

`OPT_SID` left unquoted so empty expands to nothing (no flag). Exit code 1 → no sessions in window — surface that and stop; nothing in Step 2b can rescue a missing clock report, since `enforce-profile-header.js` keys on `report.md` specifically.

Step 2b: Run analyzer — tokens/cost (best-effort, appended)

export CSID="${CLAUDE_CODE_SESSION_ID:-$PPID}"
# timeout: 60000
. "${TMPDIR:-/tmp}/foundry-profile-state-${CSID}" 2>/dev/null   # reload REPORT_DIR/SINCE/SESSION_ID/TOP_N (fresh shell)
OPT_SID=""
[ -n "$SESSION_ID" ] && OPT_SID="--session-id $SESSION_ID"
python "${CLAUDE_PLUGIN_ROOT:-plugins/cc_foundry}/bin/cost_analyzer.py" \
    --since "$SINCE" \
    --top-n "$TOP_N" \
    --output "$REPORT_DIR/cost.md" \
    $OPT_SID 2>>"$REPORT_DIR/warnings.log"
COST_EXIT=$?
if [ "$COST_EXIT" -eq 0 ] && [ -s "$REPORT_DIR/report.md" ]; then
  printf '\n' >> "$REPORT_DIR/report.md"
  cat "$REPORT_DIR/cost.md" >> "$REPORT_DIR/report.md"
fi
echo "cost_exit=$COST_EXIT"
