Token Report

Purpose

Display a compact token usage report showing per-subagent breakdown with context utilization, health status, and duration. Essential for understanding session resource consumption at a glance.

When to Use

• Quick health check during any session
• Periodic monitoring during long-running orchestration
• After subagent completion to check overall consumption
• Before deciding whether to decompose remaining work
• Post-task retrospectives on efficiency

Step 1: Check for Pre-Computed Results (MANDATORY)

CRITICAL: This skill requires hook-based pre-computation. Check context for:

PRE-COMPUTED TOKEN REPORT:

If PRE-COMPUTED TOKEN REPORT is found:

Output the table EXACTLY as provided. Do NOT modify alignment or recalculate values.

Example pre-computed output:

╭───────────────────┬────────────────────────────────┬──────────┬──────────────────┬────────────╮
│ Type              │ Description                    │ Tokens   │ Context          │ Duration   │
├───────────────────┼────────────────────────────────┼──────────┼──────────────────┼────────────┤
│ Explore           │ Explore codebase               │ 68.4k    │ 34%              │ 1m 7s      │
│ general-purpose   │ Implement fix                  │ 90.0k    │ 45% ⚠️            │ 43s        │
│ general-purpose   │ Refactor module                │ 170.0k   │ 85% 🚨            │ 3m 12s     │
├───────────────────┼────────────────────────────────┼──────────┼──────────────────┼────────────┤
│                   │ TOTAL                          │ 328.4k   │ -                │ 5m 2s      │
╰───────────────────┴────────────────────────────────┴──────────┴──────────────────┴────────────╯

If PRE-COMPUTED TOKEN REPORT is NOT found:

FAIL immediately with this message:

ERROR: Pre-computed token report not found.

The hook precompute-token-report.sh should have provided the table data.
Do NOT attempt manual computation - the alignment requires deterministic
Python-based calculation.

Possible causes:
1. Session file not found
2. No subagent data in session
3. Hook execution failed

Try running /cat:token-report again or check session status.

Do NOT proceed to manual extraction or table building.

Table Format Reference

The pre-computed table uses these specifications:

Column widths (fixed):

Column	Width	Content
Type	17	Subagent type (truncated with ...)
Description	30	Task description (truncated with ...)
Tokens	8	Formatted count (68.4k, 1.5M)
Context	16	Percentage with emoji indicator
Duration	10	Formatted time (1m 7s)

Context indicators (INSIDE column):

Context %	Display	Meaning
< 40%	"34%"	Healthy - plenty of headroom
>= 40% and < 80%	"45% ⚠️"	Warning - above soft target
>= 80%	"85% 🚨"	Critical - approaching limit

Box characters:

• Top: ╭─┬─╮
• Divider: ├─┼─┤
• Bottom: ╰─┴─╯
• Sides: │

Verification Checklist

Before outputting the table, verify:

• Pre-computed results found in context
• Table copied exactly (no modifications)
• All box characters preserved
• Emoji indicators inside Context column
• No additional computation performed

Anti-Patterns

Never attempt manual table construction

# BAD - Manual jq extraction and formatting
jq -s '...' "$SESSION_FILE"
# Then manually building table rows

# GOOD - Use pre-computed results only
# Output exactly what the hook provided

Never modify pre-computed alignment

# BAD - "Fixing" spacing or alignment
│ Type           │  # Wrong - modified padding

# GOOD - Copy exactly as provided
│ Type              │  # Correct - preserved padding
