dsh-llm-motomoto

A DeepSeek Harness bundle that adds MotoMoto to the model selector through the built-in llm-pi-ai adapter, plus a status card in Settings - Plugins modelled on the AgentRouter bundle.

The relay is Codex-only

Probing settled three facts, and the bundle is built around them:

Probe	Result
POST /v1/chat/completions (any User-Agent)	Hangs — the path is not wired
POST /v1/responses + harness User-Agent	Rejected: bad_response_status_code / openai_error
POST /v1/responses + Codex CLI User-Agent	Streams: response.created ...

So the route speaks api: openai-responses, and the runtime half fences globalThis.fetch to give relay requests the Codex client identity:

• User-Agent is rewritten to the Codex CLI value (default codex_cli_rs/0.46.0 (Windows 10.0.26200; x86_64) WindowsTerminal) — the harness's own attribution header cannot be suppressed any other way: the pi-ai adapter strips configured headers colliding with it before appending its own.
• originator: codex_cli_rs is added, matching the official client.
• Request-body fields the Codex backend rejects are deleted from JSON bodies (default strip list: max_output_tokens — the official client never sends it, and the backend answers 400 Unsupported parameter otherwise). The list is the stripBodyParams setting: the next upstream complaint is a settings edit, not a release.
• Requests to every other host pass through untouched; unloading the plugin restores the replaced fetch.

An upstream server_is_overloaded / 502 Upstream service temporarily unavailable is the relay's OpenAI pool being briefly busy — retry.

How the layers compose

dsh-settings resolves the llm-pi-ai section as mergeLayers(base, user): this bundle's patch is the base, the llm-pi-ai: section of ~/.dsh/settings.yaml merges over it — objects merge per key, arrays replace wholesale. A route you edit in the models settings page therefore wins field by field, while a fresh install still serves the default route before any user configuration exists.

The default route:

• Base URL: https://motomoto.lol/v1 (OpenAI Responses API)
• Model: gpt-5.6-terra (text input; low/medium/high reasoning efforts)
• Credential reference: MOTOMOTO_API_KEY
• Context window: 262,144

Route compat notes: the Responses protocol takes only supportsDeveloperRole, supportsStrictMode, supportsLongCacheRetention — completions-only keys (thinkingFormat, supportsReasoningEffort, chatTemplateKwargs, ...) on the same route crash the whole adapter at load.

Where to look after installing

1. Model picker — the MotoMoto group.
2. Settings - Plugins — the "MotoMoto" status card, reporting the live route (group, endpoint, credential reference, models).

Security notice

The API key is never stored in this package. Provide it as the MOTOMOTO_API_KEY credential.
