A guided assistant for Brazil’s IRPF personal income-tax return, the annual declaration submitted to Receita Federal. It checks whether you need to file, reviews the pre-filled return, and helps examine income, deductions, assets, refunds, and possible audit issues.

Use it to prepare an IRPF declaration, review a pre-filled return, check deductions and assets, estimate tax or a refund, and examine issues related to capital gains, stock trades, or the tax net.

Tax returns can contain missing or incorrect information, and the filing requirements depend on several types of income, assets, and transactions. This walks through the relevant questions and flags items to verify in the official program.

Origin original No closer match found in the catalogue.

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	$0.00063	$0.01882
Opus 5	$0.00032	$0.00941
Sonnet 5	$0.00013	$0.00376
Haiku 4.5	$0.00006	$0.00188

Measured 12d ago against content hash 343600442907, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

irpf-brasil 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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/calcular_imposto.py, scripts/dbk_parser.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

ETAPA 2 — Pré-preenchida

Perguntar:

"Você acessou a declaração pré-preenchida no Portal e-CAC ou app Meu Imposto de Renda? Se sim, o que já veio preenchido? Me informe os dados e vou avaliar se estão corretos, se falta algo ou se há algo que você pode adicionar."

Ao receber os dados pré-preenchidos:

Verificar se rendimentos batem com holerites/informes
Alertar sobre deduções que podem estar faltando
Identificar bens não declarados

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
