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.
|
|
|
|
| Fixture | Shape | Not in the public example |
|
|
| --- | --- | --- |
|
|
| `messages_tool_use.json` | Message with one `tool_use` block, `stop_reason: tool_use`, `usage` with cache fields. | The tool name and input. |

|
|
| `models_page2.json` | Last models list page, `has_more: false`. | The second model has no `display_name`, to test the fallback to `id`. |
