@cradler/dsh-plugin

Cradler Router as a provider inside DeepSeek Harness (dsh).

One API key, and Claude, GPT, Gemini, DeepSeek and Grok all show up in the dsh model picker. The model list is read live from your account, so a model added to Router appears in dsh without touching this plugin.

Install

Install into the profile you boot (dsh plugin forwards its arguments to pnpm in that profile's directory, and --profile is required):

dsh plugin --profile web add @cradler/dsh-plugin
export CRADLER_ROUTER_KEY="sk-cr-…"   # get one at https://cradler.ai/dashboard/router

Then add it to that profile's patch layer — $DSH_HOME/cordis.patch.yml for every profile, or the profile's own layer for just one:

- id: cradler-router
  name: '@cradler/dsh-plugin'

Boot dsh and pick cradler as the provider. The key is read from the environment by default, so no secret needs to be written into a config file.

Configuration

Every field has a default; the entry above needs no config: block at all.

- id: cradler-router
  name: '@cradler/dsh-plugin'
  config:
    provider: cradler

Without a key the plugin logs where to get one and registers nothing, rather than failing the harness at boot.

What it does

Registers one LlmAdapter on ctx.llm. Requests go to Router's OpenAI chat endpoint, which carries the whole catalog — including Claude and Gemini, whose native protocols dsh custom providers cannot express.

The adapter honors the harness streaming contract:

• usage is emitted immediately before the terminal finish, and nothing follows it
• block indices are allocated in first-seen order and reused across deltas
• tool-call arguments stay raw JSON strings, streamed as argumentsDelta
• token counts are disjoint — cache reads and cache writes are split out of the prompt total
• options.signal cancels in flight
• unsupported input (images) raises LlmError('UNSUPPORTED') instead of being dropped
• every request carries attributionHeaders()

Text and tool calls are supported. Image input is not: this provider advertises text-only modality and refuses image blocks rather than silently discarding them.

Alternative: no plugin

A plain custom provider works too, since Router speaks the OpenAI protocol:

llm-pi-ai:
  providers:
    cradler:
      apiKeyEnv: CRADLER_ROUTER_KEY
      api: openai-completions
      baseURL: https://router.cradler.ai/v1
      models:
        - id: claude-sonnet-4-6
        - id: gpt-5.5

npx @cradler/router-setup <key> writes that block for you, along with configs for Claude Code, Codex, Gemini CLI and others. The plugin adds a live model list and first-class provider identity on top.

Development

pnpm install
pnpm build
pnpm test        # contract tests over the chunk protocol
