🎯 Use case
This file lives under “utils/”, which covers cross-cutting helpers (shell, tempfiles, settings, messages, process input, …). On the API surface it exposes ModelConfig, CLAUDE_3_7_SONNET_CONFIG, CLAUDE_3_5_V2_SONNET_CONFIG, CLAUDE_3_5_HAIKU_CONFIG, and CLAUDE_HAIKU_4_5_CONFIG (and more) — mainly types, interfaces, or factory objects. It composes internal code from model and providers (relative imports). What the file header says: @[MODEL LAUNCH]: Add a new CLAUDE_*_CONFIG constant here. Double check the correct model strings here since the pattern may change.
Generated from folder role, exports, dependency roots, and inline comments — not hand-reviewed for every path.
