StatusLine hook that captures token telemetry from Claude Code CLI

#!/bin/bash
# Status Line hook for capturing token usage from Claude Code CLI
# Posts FULL JSON data to konsole for raw capture and telemetry aggregation

# Read JSON input from stdin
input=$(cat)

# Extract key fields for display
MODEL=$(echo "$input" | jq -r '.model.display_name // "unknown"')
SESSION_ID=$(echo "$input" | jq -r '.session_id // ""')
CONTEXT_SIZE=$(echo "$input" | jq -r '.context_window.context_window_size // 200000')
CURRENT_INPUT=$(echo "$input" | jq -r '.context_window.current_usage.input_tokens // 0')
CURRENT_OUTPUT=$(echo "$input" | jq -r '.context_window.current_usage.output_tokens // 0')
TOTAL_INPUT=$(echo "$input" | jq -r '.context_window.total_input_tokens // 0')
TOTAL_OUTPUT=$(echo "$input" | jq -r '.context_window.total_output_tokens // 0')
TOTAL_COST=$(echo "$input" | jq -r '.cost.total_cost_usd // 0')

# Calculate usage percentage
PERCENT_USED=0
if [ "$CONTEXT_SIZE" -gt 0 ]; then
  PERCENT_USED=$(( (CURRENT_INPUT + CURRENT_OUTPUT) * 100 / CONTEXT_SIZE ))
fi

# Post FULL JSON to konsole if we have meaningful data
if [ "$CURRENT_INPUT" -gt 0 ] || [ "$CURRENT_OUTPUT" -gt 0 ]; then
  # Fire and forget - don't block the status line
  (echo "$input" | jq -c '. + {receivedAt: ...}' | \
    curl -s -X POST "http://localhost:8020/statusline" \
      -H "Content-Type: application/json" \
      -d @- > /dev/null 2>&1 &)
fi

# Output status line display
printf "[%s] %d%% | $%.4f | %dK in/%dK out" ...

How it works

Trigger	Runs every ~300ms during active Claude turns
Input	Full JSON from Claude Code CLI on stdin
Action	POSTs to `localhost:8020/statusline` (konsole)
Output	Formatted status: `[Opus] 45% \| $0.0234 \| 15K in/4K out`
Storage	Raw JSONL at `/konnectvol/konsole/data/statusline-raw.jsonl`
