feat(anthropic): support Claude Fable 5 adaptive thinking#91882
Conversation

Codex review: needs maintainer review before merge. Reviewed June 10, 2026, 4:01 AM ET / 08:01 UTC. Summary PR surface: Source +491, Tests +1006, Docs +11. Total +1508 across 43 files. Reproducibility: yes. The linked report provides API-level failure messages for Fable 5, and current main has no Fable-specific adaptive-thinking path, so the failure mode is source-reproducible even though I did not run a live credential repro here. Review metrics: 2 noteworthy metrics.
Merge readiness Overall follows the weaker of proof and patch quality, so missing proof can cap an otherwise strong patch. Risk before merge

Next step before merge
Security Review detailsBest possible solution: Land this branch after final maintainer review accepts the provider-surface changes and either accepts the test-only Vertex coverage or requests a live Vertex credential proof. Do we have a high-confidence way to reproduce the issue? Yes. The linked report provides API-level failure messages for Fable 5, and current main has no Fable-specific adaptive-thinking path, so the failure mode is source-reproducible even though I did not run a live credential repro here. Is this the best way to solve the issue? Yes, with maintainer review. The PR uses shared provider/model helpers and keeps direct Anthropic, transport, Vertex, replay, and agent reasoning state aligned rather than adding a one-off request patch. AGENTS.md: found and applied where relevant. Codex review notes: model gpt-5.5, reasoning high; reviewed against e3fe6715afb6. Label changesLabel changes:

The re-export at line 6 references resolveClaudeModelIdentity but it was never imported. This was introduced by openclaw#91882 which added the Fable 5 adaptive thinking support and accidentally dropped the import while narrowing the import list.

Summary

Behavior addressed: Claude Fable 5 works through the canonical Anthropic model policy and direct provider path, with shared behavior for Vertex, Bedrock, and Anthropic-compatible deployment aliases.
Real environment tested: AWS Crabbox Linux with a real Anthropic API credential; GCP Crabbox Linux metadata/ADC path; AWS Crabbox Bedrock discovery path.
Exact steps or command run after this patch: built the synced checkout and ran isolated
openclaw agent --local --model anthropic/claude-fable-5 --thinking <level> --jsonturns foroff,minimal,xhigh, andmax; separately loaded the Vertex plugin from an installed-plugin-shaped temporary root and attempted a native Bedrock discovery/agent flow.Evidence after fix: https://crabbox.openclaw.ai/portal/runs/run_902b34e2bb9e
Observed result after fix: all four direct Anthropic calls returned their exact marker; execution metadata reported provider
anthropic, modelclaude-fable-5, terminalstop, and no fallback.What was not tested: authenticated Vertex, Bedrock, and Microsoft Foundry model calls. No valid Vertex service-account scope, Bedrock credential, or Foundry deployment credential exists in the configured environment; the PR records the exact provider-side blockers above rather than substituting mocks.
Release note
Anthropic: add Claude Fable 5 across direct API, Vertex, Bedrock, and Anthropic-compatible deployment aliases, including adaptive-thinking defaults, replay safety, refusal handling, and canonical model metadata.
