haylanandClaude-Bot 6f4e736da8 docs(coding-cli-setup): split per-CLI docs into their own files
Move docs/coding-cli-setup.md to docs/coding-cli-setup/ with one file
per CLI (claude-code, kimi-cli, opencode, qwen-code) plus a shared
index.md for the gateway intro, tool-calling risk note, and summary
table.

Also fixes the qwen-code doc: context sizes are per-slot
(LLAMA_CTX_SIZE / LLAMA_PARALLEL), not raw LLAMA_CTX_SIZE (same fix
applied to OpenCode's limit.context); documents the fastModel
classifier provider and its own context math; adds the omniroute-search
MCP server (SearXNG web search) and Auto Mode permissions tuning that
were missing from the original qwen-code section.

OpenCode CLI

← back to overview

Confirmed project: anomalyco/opencode (renamed from sst/opencode — don't confuse with the unrelated opencode-ai/opencode Go TUI). Docs: https://opencode.ai/docs/

Install:

curl -fsSL https://opencode.ai/install | bash

Config (opencode.json, project root or ~/.config/opencode/opencode.json):

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "aiproxy": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "AI proxy (local)",
      "options": {
        "baseURL": "http://<ai-box>:${OMNIROUTE_PORT:-4000}/v1",
        "apiKey": "<opencode-cli virtual key>"
      },
      "models": {
        "qwen3.8-27b-local": {
          "name": "Qwen3.8-27B",
          "limit": { "context": 65536, "output": 8192 }
        }
      }
    }
  }
}

Set limit.context to the per-slot context this stack actually serves — LLAMA_CTX_SIZE / LLAMA_PARALLEL from .env (262144 / 2 = 131072 by default), not raw LLAMA_CTX_SIZE and not a value assumed from the model card: llama.cpp divides --ctx-size across concurrent slots, so each request only gets one slot's share. OpenCode uses this for its own context-management bookkeeping, not the server.

Select the model with aiproxy/qwen3.8-27b-local.

OpenCode-specific risks (on top of the shared Qwen3.8-27B tool-calling risk — see overview):

  • Requires llama.cpp's --jinja flag (already set) — without it, OpenCode's unconditional tool-call scaffolding gets a 500.
  • anomalyco/opencode#20669 (closed as "not planned" — a live, unfixed risk): OpenCode's bash tool crashes if the model omits the optional description field on a tool call; some local backends return finish_reason: tool_calls with an empty array, which can hang the agent loop instead of stopping cleanly.
  • Thinking-mode handling (options.reasoningEffort) is undocumented for models that emit inline <think> tags rather than a native reasoning API field — expect no effect from that config on this model; untested.
