Multiple bugs and fixes related to tool/function schemas using top-level combinators (anyOf, allOf, oneOf) that are rejected by OpenAI, Anthropic, and Codex APIs. A recurring concern is the schema sanitizer stripping or corrupting valid properties like dependentRequired while attempting to normalize schemas.

How this cluster was grouped
  • Link evidence (partly structural links): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
  • Members outside that structural core may belong to a different underlying problem.
  • Pairwise link density 0.12: the share of item pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. 1.00 means every pair is linked.
