What it does

• Self-healing client identity. Derives the OpenCode CLI wire identity at the current release commit SHA and updates automatically when upstream tightens the gate.
• Live catalog discovery. Reads models.opencode.ai/api.json (and /v1/models) to expose only active free-tier models (cost.input === 0, non-deprecated) and reject retired or paid model IDs locally with a clear error.
• Dual-protocol support. Routes requests to /inference/openai/v1/chat/completions or /inference/openai/v1/responses based on catalog metadata and automatic protocol-mismatch detection.
• Reasoning-aware token budgeting. Applies an additive token floor (max(requested, 1024) + 4096) for reasoning models (determined from catalog reasoning: true metadata) so short prompts do not return empty content with finish_reason: "length"
• Reasoning stream normalization. Emits thinking tokens under reasoning_content for both streaming SSE and non-streaming JSON responses, and forwards client tool calls with automatic name de-collision (read -> read_client upstream, restored t
