Add internal/ai/llm/anthropic, an llm.Provider over plain net/http:
- POST {base}/v1/messages and GET {base}/v1/models with x-api-key and
anthropic-version 2023-06-01. An empty key, a non-positive
Config.MaxTokens and a base URL that is not absolute http(s), or that
carries userinfo, a query or a fragment, are construction errors.
- System text goes in the top-level system field. A Request with a
Schema becomes one tool whose input_schema is the schema, forced by
tool_choice; Response.JSON is that tool's input. Otherwise the text
blocks are Response.Text. Usage and stop_reason are parsed.
- ListModels follows has_more/after_id pages; Verify fetches one page
with limit=1.
- 401/403 map to ErrAuth, 429 and 529 to ErrRateLimited with
Retry-After, 408 and deadlines to ErrTimeout, other statuses to
ErrProvider with a redacted excerpt.
- Errors carry the OpenAI adapter's redaction chain, so no Error(),
Unwrap layer, errors.As target or %#v output holds the key.
Contract tests replay sanitized fixtures adapted from Anthropic's public
Messages API docs over httptest, covering tool-forced JSON, text, each
error mapping and key redaction with the keys x-api-key, anthropic,
HTTP, rate, a one-letter key and a URL-escaped key.

Anthropic adapter fixtures
These are the Messages API response bodies the contract tests in
anthropic_test.go replay. They are not live captures. Product AI is
tested with fakes, and live vendor calls are opt-in and never use
credentials, so no request was sent to Anthropic to make them. Each fixture
is a sanitized adaptation of the response shapes in Anthropic's public API
documentation:
- Messages: https://docs.anthropic.com/en/api/messages
- Tool use, including
tool_choice{type: tool}: https://docs.anthropic.com/en/docs/build-with-claude/tool-use - List models: https://docs.anthropic.com/en/api/models-list
- Errors: https://docs.anthropic.com/en/api/errors
Sanitizing:
- IDs, request IDs, timestamps and token counts are illustrative values in the documented format, not values from a real account.
- Message content and tool input are replaced with MealQuest dinner text.
- No real credential appears anywhere.
{{KEY}}is a placeholder the tests replace with a fake key, to prove the adapter redacts a key echoed back in a vendor body.
Below, not in the public example marks fields or values that were added for a test case and do not come from the documented example.
