cost-today is a command for Claude Code from hoangsonww/Claude-Code-Agent-Monitor. It costs 16 tokens per session (315 once invoked), scanned A, original, MIT.

A quick cost summary from the Agent Monitor pricing engine, including total spend and a breakdown by model. A model is the AI system that processes the request.

In plain words
What is it for?
Checking total cost, comparing model costs, and reviewing input, output, cache-read, and cache-write token counts.
Why use it?

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-today scanned grade A with 1 finding 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 12d 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.

What it actually says

Print a quick cost snapshot from the Agent Monitor dashboard pricing engine.

The user's scope is $ARGUMENTS (default today if empty; accepts today or week).

Fetch the fleet-wide cost breakdown:

curl -s http://localhost:4820/api/pricing/cost

This returns { total_cost, breakdown: [{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] }.

Then print, concisely:

  1. Total costtotal_cost as USD to 4 decimal places, labeled with the scope ($ARGUMENTS).
  2. Per-model one-liners — one line per entry in breakdown, sorted by cost descending: <model> — $<cost to 4dp> (in <input_tokens>, out <output_tokens>, cacheR <cache_read_tokens>, cacheW <cache_write_tokens>)

Keep token counts with thousands separators. No tables, no preamble — just the total and the per-model lines.

Note: the endpoint returns lifetime totals; if the user asked for today or week and the data is not scoped, say so in one line rather than fabricating a windowed number. If the dashboard is unreachable, tell the user to start it with npm start from the repo root.

Changes

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.
