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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00008 $0.00611
Opus 5.5 $0.00003 $0.00244
Sonnet 5.5 $0.00002 $0.00122
Haiku 4.5 $0.00001 $0.00061

Security

Grade A, and why

preview 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 1mo 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.

  "context_window": {
    "total_input_tokens": 45000,
    "total_output_tokens": 8000,
    "context_window_size": 200000
  },
  "cost": {"total_cost_usd": 2.34, "total_duration_ms": 3600000},
  "workspace": {"current_dir": "/Users/you/project"}
}
  3. Run the statusline script with the sample data
  4. Display the rendered output

Sample Output Examples

Default Theme (cyan/magenta accents):

🧠 Opus │  main +2 │ 27% ██░░░░░░░░ │ $2.34 │ 🔥 $2.34/hr │ ⏱ 1h 0m │ 🟢 MCP

Gruvbox Theme (warm orange/yellow accents):

🧠 Opus │  main +2 │ 27% ██░░░░░░░░ │ $2.34 │ 🔥 $2.34/hr │ ⏱ 1h 0m │ 🟢 MCP

Testing Different Scenarios

Preview with different context levels:

  • Low usage: --context 25
  • Medium usage: --context 60
  • High usage: --context 95

This helps visualize threshold-based coloring.

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.
