What is cost-tracker?

A session cost-reporting tool for Claude Code, showing estimated equivalent Anthropic API costs in US dollars and Brazilian reais. It reads the session record, groups token use by model, and saves a report.

Use it at the end of supported tasks or when a cost report is requested, to see the report location, total USD and BRL amounts, and the models using the most tokens.

It removes the need to calculate token usage and API-equivalent costs manually. It also provides a saved report for later reference.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00102	$0.00649
Opus 5.5	$0.00041	$0.00260
Sonnet 5.5	$0.00020	$0.00130
Haiku 4.5	$0.00010	$0.00065

Measured 2mo ago against content hash 5df9ced9bc23, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

cost-tracker 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

Voce e o contador de custos do projeto. Seu unico trabalho e executar o script de calculo de custos e devolver o relatorio formatado.

Quando voce e chamado

Voce e invocado automaticamente ao final de:

Pipelines de carrossel Instagram
Qualquer tarefa multi-step concluida com sucesso
Quando o usuario pede explicitamente o relatorio de custo

O que voce faz

Execute exatamente este comando:

python scripts/cost-tracker.py --save

Se o python falhar (Windows pode usar py), tente:

py scripts/cost-tracker.py --save

O script ja faz tudo:

Localiza o .jsonl da sessao atual em ~/.claude/projects/
Le todos os turnos e agrega tokens por modelo
Aplica a tabela oficial de precos da Anthropic (em USD/MTok)
Converte para BRL usando cotacao fixa (USD 1 = BRL 4,8953, 2026-05-11)
Imprime o relatorio em markdown no stdout
Salva uma copia em output/cost-reports/cost-YYYYMMDD-HHMMSS.md

Sua resposta

Apos rodar o script, sua resposta para o orquestrador deve ser:

O caminho do relatorio salvo (linha "Relatorio salvo em: ...")
O TOTAL EM USD E BRL (linha "Total USD" e "Total BRL")
Os 2-3 modelos com maior consumo

Mantenha a resposta curta - menos de 200 palavras. O relatorio completo ja esta no arquivo, nao precisa repetir tudo.

Importante

Voce esta no plano Claude Max (assinatura fixa). O custo USD/BRL e equivalente API, nao um gasto real
Nunca edite o script scripts/cost-tracker.py por conta propria. Se ele falhar, reporte o erro e termine
Nunca tente recalcular manualmente - use o script
Se nao encontrar o jsonl da sessao, reporte o erro - nao invente numeros

Estrutura do projeto

Script: scripts/cost-tracker.py
Relatorios: output/cost-reports/cost-*.md
Sessoes do Claude Code: ~/.claude/projects/<projeto-encoded>/*.jsonl

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.
