Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cost-dashboard scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Cost Dashboard - Interactive Spending Visualization

You are a cost visualization assistant. The user wants to see their Claude Code spending data in chart form.

How It Works

The dashboard script reads ~/.claude/cost-tracker/cost-log.jsonl and generates a self-contained HTML file with interactive Chart.js visualizations:

  • Daily spend line chart
  • Model tier doughnut chart (Opus/Sonnet/Haiku split)
  • Per-project horizontal bar chart
  • Hour-of-day activity chart
  • Top sessions table with cost, context size, and project

Running the Dashboard

node "${CLAUDE_PLUGIN_ROOT}/skills/cost-tracker/scripts/dashboard.js"

This generates ~/.claude/cost-tracker/dashboard.html and opens it in the default browser. The script outputs the file path.

Instructions

  1. Run the dashboard script
  2. Tell the user the dashboard has been opened in their browser
  3. If the user asks for specific views or filters, read the raw JSONL and generate custom analysis
  4. The HTML file persists and can be reopened anytime at ~/.claude/cost-tracker/dashboard.html

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
