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 | $0.06326 | $0.06326 |
| Opus 5.5 | $0.02530 | $0.02530 |
| Sonnet 5.5 | $0.01265 | $0.01265 |
| Haiku 4.5 | $0.00633 | $0.00633 |
Grade A, and why
codesteer-atlas AGENTS.md 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 23d 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.
How it starts
The opening of the file, as written. The whole thing — 305 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Busca de código (MCP codesteer-atlas)
Use as tools do MCP antes de grep, rg, find, glob ou leitura em massa.
| Objetivo | Tool |
|---|---|
| Se orientar num projeto desconhecido (chame primeiro, uma vez) | atlas_brief |
| Pacote da tarefa quando o símbolo/arquivo já é conhecido | atlas_context |
| Onde algo está implementado | atlas_search |
Conectividade, hubs, rationale e impacto (affected) |
atlas_graph |
| Diagnóstico do índice | atlas_status |
| (Re)indexar | atlas_index |
Quando a tarefa já tem um símbolo ou arquivo, chame atlas_context(target, intent) primeiro (edit / debug / review / understand) em vez de encadear atlas_graph + atlas_brief. Use atlas_graph(mode="affected") para o raio de impacto.
atlas_search (2 passos): retorna só metadados por padrão — localize com
path_prefix/language/top_k baixo; depois Read nas linhas ou
include_content=true nos poucos hits relevantes. Não chame atlas_status antes:
se o índice não existir, a própria tool explica como criá-lo.
grep/Read só depois que o Atlas indicar o arquivo: confirmar string ou erro
literal, ler caminho que o usuário já deu, editar, diff, commit, git, CI ou testes.
Fallback se o MCP estiver indisponível, a autenticação falhar, ou o índice estiver
vazio ou desatualizado.
Índice desatualizado: atlas_status com is_stale: true (HEAD indexado diferente
do workspace), reindexar com atlas_index, e só então usar grep/Read como
recorte do momento — reindexar de novo ao fim da sessão.

Frescor e cobertura do índice
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.
