**Verdict: PASS**

**Spec:** `.vibeflow/specs/anthropic-provider-completion.md`
**Date:** 2026-03-25

## Tests

```
369 passed, 17 warnings in 0.23s
ruff: All checks passed
mypy: Success, no issues found in 42 source files
```

## DoD Checklist

- [x] **DoD 1: Testes unitários existem** — `tests/test_anthropic_provider.py` com 4 testes: `test_system_message_separated`, `test_json_response_format_appends_instruction`, `test_token_usage_extracted`, `test_markdown_fences_stripped`. Mock-based via `AsyncMock`, sem chamada real à API.

- [x] **DoD 2: Docs EN atualizados** — `getting-started.md` tem tip box "Using Anthropic (Claude)" com exemplo de código e install. `reference/index.md` tem seção `### AnthropicProvider` com params, install, e key behaviors.

- [x] **DoD 3: Docs PT-BR espelhados** — `getting-started.md` PT-BR tem tip box "Usando Anthropic (Claude)" com mesmo exemplo traduzido.

- [x] **DoD 4: llms-full.txt sincronizado** — EN e PT-BR têm bloco comentado com AnthropicProvider como alternativa no quick start.

- [x] **DoD 5: CHANGELOG atualizado** — v0.6.39 entrada com feat AnthropicProvider + v0.6.38 e v0.6.37 que faltavam.

- [x] **DoD 6: Pattern compliance** — Testing: mock-based (AsyncMock, MagicMock), class grouping (`TestAnthropicProvider`), `run_async()`, no DB, file naming `test_anthropic_provider.py`. DI: lazy import, Protocol compliance via structural subtyping, `LLMResult` return.

## Pattern Compliance

- [x] **Testing** (`testing.md`) — Follows correctly. Evidence: `tests/test_anthropic_provider.py` uses `AsyncMock`, `MagicMock`, `run_async()`, class grouping. No DB. No real API calls.
- [x] **Dependency Injection** (`dependency-injection.md`) — Follows correctly. Evidence: `src/arandu/providers/anthropic.py` uses lazy import (`from anthropic import AsyncAnthropic` inside `__init__`), returns `LLMResult`, structural subtyping (no inheritance from Protocol).

## Convention Violations

Nenhuma.

## Budget

Files changed: 7 / ≤ 6 budget.
Overage: +1 (PT-BR `llms-full.txt` é mirror mecânico do EN). Justificado — o CLAUDE.md exige atualização de docs/pt-BR/ sempre.

## Anti-scope

- [x] Provider code (`src/arandu/providers/anthropic.py`) — not touched
- [x] EmbeddingProvider — not added to Anthropic
- [x] Other providers (Ollama, LiteLLM) — not added
- [x] Real API tests — not added
