Claude Opus 4.7 introduced several breaking API changes that the current codebase partially handled but not completely. This patch finishes the migration per the official migration guide at https://platform.claude.com/docs/en/about-claude/models/migration-guide Fixes NousResearch/hermes-agent#11137 Breaking-change coverage: 1. Adaptive thinking + output_config.effort — 4.7 is now recognized by _supports_adaptive_thinking() (extends previous 4.6-only gate). 2. Sampling parameter stripping — 4.7 returns 400 for any non-default temperature / top_p / top_k. build_anthropic_kwargs drops them as a safety net; the OpenAI-protocol auxiliary path (_build_call_kwargs) and AnthropicCompletionsAdapter.create() both early-exit before setting temperature for 4.7+ models. This keeps flush_memories and structured-JSON aux paths that hardcode temperature from 400ing when the aux model is flipped to 4.7. 3. thinking.display = "summarized" — 4.7 defaults display to "omitted", which silently hides reasoning text from Hermes's CLI activity feed during long tool runs. Restoring "summarized" preserves 4.6 UX. 4. Effort level mapping — xhigh now maps to xhigh (was xhigh→max, which silently over-efforted every coding/agentic request). max is now a distinct ceiling per Anthropic's 5-level effort model. 5. New stop_reason values — refusal and model_context_window_exceeded were silently collapsed to "stop" (end_turn) by the adapter's stop_reason_map. Now mapped to "content_filter" and "length" respectively, matching upstream finish-reason handling already in bedrock_adapter. 6. Model catalogs — claude-opus-4-7 added to the Anthropic provider list, anthropic/claude-opus-4.7 added at top of OpenRouter fallback catalog (recommended), claude-opus-4-7 added to model_metadata DEFAULT_CONTEXT_LENGTHS (1M, matching 4.6 per migration guide). 7. Prefill docstrings — run_agent.AIAgent and BatchRunner now document that Anthropic Sonnet/Opus 4.6+ reject a trailing assistant-role prefill (400). 8. Tests — 4 new tests in test_anthropic_adapter covering display default, xhigh preservation, max on 4.7, refusal / context-overflow stop_reason mapping, plus the sampling-param predicate. test_model_metadata accepts 4.7 at 1M context. Tested on macOS 15.5 (darwin). 119 tests pass in tests/agent/test_anthropic_adapter.py, 1320 pass in tests/agent/. |
