Review round 1 fixes (1 Critical + 5 Important) on the anthropic
adapter/translator.
- CRITICAL: consecutive role:"tool" messages each became their own
Anthropic user turn. Anthropic requires alternating user/assistant
turns and 400s on two consecutive same-role messages; parallel tool
calls (one assistant message with N tool_calls followed by N
role:"tool" messages) are the standard agentic transcript shape.
anthropicRequestFromOpenAI now accumulates consecutive tool messages
into one Anthropic user turn carrying all of their tool_result
blocks (anthropicToolResultBlock replaces anthropicToolResultMessage).
Added chat_parallel_tool_results fixture.
- Streaming tool_calls[].index passed Anthropic's raw content-block
index through, so a tool_use block after a text block emitted
index:1 instead of the required contiguous 0-based ordinal.
anthropicStreamState now tracks a per-stream tool-call ordinal
counter plus a content-block-index -> ordinal map, populated on
content_block_start and consulted on input_json_delta. Added the
stream_text_then_tool fixture (text block at index 0, tool_use at
index 1) proving the emitted index is 0.
- A system message with array-form content ([{"type":"text",...}])
was silently dropped (only a string content was handled). Added
systemTextFromContentParts: text parts join with "\n"; a non-text
part returns a *translateError instead of being dropped. Added
chat_system_array_content (success) and
chat_system_array_content_error fixtures.
- Malformed JSON on a recognized stream event (message_start,
content_block_start, content_block_delta, message_delta) was
swallowed as (nil, nil), which could silently corrupt a client's
reassembled tool-call arguments. All four now return an error
wrapping errUpstream; forwardStream already propagates that and
withholds the terminal [DONE]. The unrecognized-event-type and
error-event branches are unchanged. Added
TestAnthropicStreamState_MalformedEventReturnsError.
- providerAdapter.injectAuth's doc comment claimed a universal
empty-key no-op; updated to state the per-type divergence
(openai-type: keyless is a no-op; anthropic-type: the constructor
rejects an empty key, so injectAuth is never called with one).
- Added case-insensitive-Content-Type coverage for both adapters'
streaming-vs-JSON gate (previously untested): one subtest each in
provider_openai_test.go / provider_anthropic_test.go using a fake
upstream that sends "Text/Event-Stream; charset=utf-8", asserting
the streaming path (not the JSON fallback) is taken.
Gate: go test ./... -count=1 and -race both green; gofmt, go vet,
fieldalignment, golangci-lint (incl. gosec), govulncheck all clean.
