PR Summary

Low Risk
Catalog and comment-only removal with no changes to request paths for remaining models; existing workflows on other Claude IDs are unaffected.

Overview
Removes claude-fable-5 from the Anthropic provider catalog in models.ts, so it no longer appears in pickers or pricing/capability lookups.

In anthropic/core.ts, drops fable-5 from supportsAdaptiveThinking and updates related comments so adaptive-thinking docs no longer mention Fable 5.

Greptile Summary

This chore removes the claude-fable-5 model that was added but is no longer needed — its entry is deleted from the Anthropic provider model list in models.ts, and the related fable-5 branch and TSDoc are cleaned up in anthropic/core.ts.

• Removes the full claude-fable-5 model definition (pricing, capabilities, 1 M token context window, release date 2026-06-09) from the Anthropic provider in models.ts.
• Drops the normalizedModel.includes('fable-5') guard from supportsAdaptiveThinking() and updates the function-level comment in core.ts to match.

Confidence Score: 5/5

Straightforward model-entry removal with no logic changes — safe to merge.

Both touched files are limited to deleting a single model definition and its single detection branch. No logic is restructured, no other models are affected, and the remaining supportsAdaptiveThinking branches are unchanged and correct.

No files require special attention.

Important Files Changed
