dsh-jev
A DeepSeek Harness plugin that gives any DSH agent a native Jev capability.
Jev is TypeSafe's System One model. It returns typed noul, choice, and score answers. It does not generate chat or code. This plugin registers jev_ask so the session LLM, Code mode, and other DSH agents can call Jev the same way they call bash.
Install
Build once, then add the package to a profile.
pnpm install
pnpm run build
dsh plugin --profile web add /absolute/path/to/dsh-jev
From GitHub after you allow the prepare build:
dsh plugin --profile web add github:noetion/dsh-jev
Set TYPESAFE_API_KEY in the process environment, or store that same name in DSH credentials. The plugin reads the key on every call. It does not put the secret in cordis.yml.
Use
Ask the agent to call jev_ask, or invoke the bundled jev skill. One call can mix question types over the same state.
{
"state": "Help! My payouts have been failing for 3 days.",
"questions": {
"is_urgent": {
"type": "noul",
"instructions": "Does this convey urgency?"
},
"department": {
"type": "choice",
"instructions": "Which team should handle this?",
"criteria": {
"billing": "Payments, invoicing, refunds",
"technical": "Bugs, outages, integrations",
"sales": "Pricing, upgrades, new accounts"
}
}
}
}
The tool result is the TypeSafe JSON. Your agent branches on answers.<id>.noul, .choice, .score, and .confidence.
Configure
Optional cordis.yml fields on the jev row:
model, default jev-latestendpoint, default https://api.typesafe.ai/v1/systemoneapiKeyEnv, default TYPESAFE_API_KEY
Develop
pnpm install
pnpm run check
pnpm run check typechecks, runs the mock HTTP tests, and builds the bundle.
Live TypeSafe proof, with a key in the environment:
pnpm run live
Install-and-load proof against a throwaway DSH_HOME:
pnpm run verify-boot
@deepseek-ai/dsh-tools is pinned to 0.1.5-rc.2 (the next dist-tag). npm latest is a stale 0.0.1-rc.1. Do not replace the pin with an untagged install.
Why this is not an LLM adapter
An LLM adapter must stream text and tool-call chunks. Jev answers typed questions. Wiring it as a chat provider would be a lie. The native DSH seam for Jev is a tool plus, when the profile has ctx.skills, a bundled skill.
