@tanstack/ai-claude-code@0.9.0

Minor Changes

• #1692 7532b2b - Set reasoning with chat({ reasoning }).

  • A model with effort levels gets --effort <level>.
  • A budget model (Haiku) gets MAX_THINKING_TOKENS with the budget, or 0 for off.
  • The reasoning data is in model-meta.ts, keyed by model id. ClaudeCodeModelReasoningByName and CLAUDE_CODE_MODEL_REASONING come from it.

  Breaking: none. The adapter had no reasoning option before.

  chat({
    adapter: claudeCodeText('claude-opus-4-8'),
    messages,
    reasoning: 'xhigh',
  })

Patch Changes

• #1692 7532b2b - The CLI-style adapters follow chat({ toolChoice }) where they can.

  • Claude Code. 'none' and a named tool turn off the built-in tools. The adapter then bridges none of your tools, or only the named one. 'required' logs a warning.
  • Codex, OpenCode, Grok Build, and ACP-compatible adapters. 'none' and a named tool limit only your bridged tools. The built-in tools of the agent stay on, so these values and 'required' log a warning.

• Updated dependencies [1bfcee3, 412b0fe, a0150c2, b881627, fac0555, 6774e80, 5bd27f2, c20f7b0, cef1911, 51f72fb, 6f1e559, cef1911, 7532b2b, 1bfcee3, 78edeb2, 44e3a0a, 7532b2b, 7a5c0d6, b881627]:
