Decidealot

Your hardware. Local decision models. Run Laya and Von through TypeSafe-compatible HTTP or MCP.

At startup Decidealot downloads and verifies both local model bundles. It then loads only the model selected by a request, unloads it after the configured idle period, and returns typed choice, score, and noul answers with model probabilities. It exposes the TypeSafe HTTP API and MCP Streamable HTTP from the same local container.

Quick start

You need Docker. This starts the CPU image on loopback, stores downloaded model files in one narrow host directory, and gives the container no capabilities or writable root filesystem.

model_directory="$HOME/.local/share/decidealot/models"
runtime_uid=$(id -u)
runtime_gid=$(id -g)
mkdir --parents "$model_directory"

docker run --detach --name decidealot --init --restart unless-stopped \
  --user "$runtime_uid:$runtime_gid" \
  --read-only --cap-drop ALL --security-opt no-new-privileges:true \
  --pids-limit 512 --memory 8g --cpus 4 \
  --tmpfs /tmp:rw,noexec,nosuid,size=128m \
  --tmpfs /var/run:rw,noexec,nosuid,size=8m \
  --log-driver json-file --log-opt max-size=10m --log-opt max-file=5 \
  --mount type=bind,source="$model_directory",target=/models \
  --publish 127.0.0.1:8080:8080 \
  psyb0t/decidealot:v0.4.0

Check the service, then ask Laya to make one typed decision:

curl --fail http://127.0.0.1:8080/health

curl --fail http://127.0.0.1:8080/v1/systemone \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "laya",
    "state": "A proposed action would permanently delete protected data.",
    "questions": {
      "handling": {
        "type": "choice",
        "instructions": "Choose the required handling for this action.",
        "criteria": {
          "allow": "The action is reversible and does not affect protected data.",
          "require_review": "The action is irreversible or affects protected data."
        }
      }
    }
  }'

The first service startup downloads both pinned model bundles and can take several minutes. Wait for /health before sending a decision. Later service starts reuse the same host directory. The response includes answers.handling.choice and a probability per choice key. Your caller chooses what to do with that decision, for example only allowing allow when its probability meets your own threshold.

Use the API

Send the state to judge and a bounded question. Decidealot returns typed results with probabilities.

choice questions need named criteria. score questions need an ordered criteria array whose position is the score. noul questions return a probability between zero and one. The API guide has the request rules, response shape, validation failures, aliases, authentication, and lifecycle behavior.

Use MCP

The same container serves MCP Streamable HTTP at http://127.0.0.1:8080/mcp. The system_one tool takes the same model, state, and questions fields as POST /v1/systemone. list_models returns the live catalog. unload_models releases local model memory.

Point an MCP client at that exact URL. Its configuration format varies, but the connection values are always equivalent to this:

{
  "mcpServers": {
    "decidealot": {
      "url": "http://127.0.0.1:8080/mcp",
      "headers": {
        "Authorization": "Bearer your-token-here"
      }
    }
  }
}

Omit the Authorization header only when DECIDEALOT_API_KEY is empty. The MCP tools return structured output matching the HTTP result bodies, so an agent can inspect probabilities before it chooses the next action. A client that only supports local stdio can use the optional OpenClaw bridge described in Agent integrations. The API guide has tool inputs, output shapes, session behavior, and failure behavior.

Pick a model

Every request must name a selector. GET /v1/models returns the same catalog at runtime.

What differs

Laya is one model family with three checkpoints. Its automatic selectors choose English or multilingual checkpoints from the input script and a language heuristic. Use laya-multilingual for known non-English short Latin-script messages. laya-typed-decisions targets repeated structured decision work.

Von is a separate English-only decision model for short questions with clear criteria. Both models take the same TypeSafe state and questions shape and return typed choice, score, and noul answers with probabilities. Your application applies the threshold and action that follow.

Decidealot keeps one provider resident. Moving between Laya selectors stays in the Laya provider. Moving between Laya and Von waits for active work, releases the old provider and its Torch memory, then starts the other one.

Set DECIDEALOT_PROVIDER_IDLE_UNLOAD_SECONDS to choose when an idle provider releases its model and Torch memory.

Configuration

Pass configuration with --env-file or your container manager. The image uses fixed internal ports. Docker port publishing controls where the service is reachable.

The container always stores bundles under /models. Its only model storage setting is the host directory mounted there. Keep the loopback bind for one-host use. Before putting Decidealot behind a proxy, tunnel, or public address, set DECIDEALOT_API_KEY to a real secret and require Authorization: Bearer <your-key> from every caller.

CUDA

psyb0t/decidealot:v0.4.0-cuda uses CUDA 12.6 and needs a compatible NVIDIA driver, NVIDIA Container Toolkit, and --gpus all. CUDA images are amd64-only. The CPU image is the right default unless inference speed and model memory justify the GPU setup.

model_directory="${model_directory:-$HOME/.local/share/decidealot/models}"
runtime_uid=$(id -u)
runtime_gid=$(id -g)
mkdir --parents "$model_directory"

docker run --detach --name decidealot --init --restart unless-stopped \
  --user "$runtime_uid:$runtime_gid" \
  --gpus all --read-only --cap-drop ALL --security-opt no-new-privileges:true \
  --pids-limit 512 --memory 8g --cpus 4 \
  --tmpfs /tmp:rw,noexec,nosuid,size=128m \
  --tmpfs /var/run:rw,noexec,nosuid,size=8m \
  --tmpfs /var/cache:rw,exec,nosuid,nodev,size=512m,uid=$runtime_uid,gid=$runtime_gid,mode=0755 \
  --log-driver json-file --log-opt max-size=10m --log-opt max-file=5 \
  --mount type=bind,source="$model_directory",target=/models \
  --publish 127.0.0.1:8080:8080 \
  psyb0t/decidealot:v0.4.0-cuda

CUDA needs one writable executable cache because Triton compiles and loads short-lived CUDA helpers there. The rest of the container remains read-only and noexec. Deployment has the complete CPU, CUDA, authentication, persistent-storage, and host-directory recipes.

Model storage and unloading

Mount one narrow host directory at /models. Decidealot creates and manages /models/laya and /models/von inside it. The Docker commands run as your current host UID and GID, so a directory you create yourself is writable without an image-specific chown. The image falls back to non-root 1000:1000 only when no runtime user is supplied.

Unload the loaded runtime when you are done with it:

curl --fail --request POST http://127.0.0.1:8080/v1/models/unload

Only one provider can be loaded, but the endpoint reports both providers so the result is clear. Unload terminates the provider process, so it releases model weights, Torch allocations, worker threads, and the CUDA context. A later request starts it again.

Agent integrations

Install the Decidealot skill from the psyb0t marketplace after the release that contains it. The skill tells an agent how to deploy the Docker image, choose Laya or Von, submit TypeSafe decisions, read probabilities, use direct MCP, and use the stdio bridge only when its client needs one.

claude plugin marketplace add psyb0t/agents
claude plugin install decidealot@psyb0t

codex plugin marketplace add psyb0t/agents
codex plugin add decidealot@psyb0t

OpenClaw can install the skill or its stdio bridge. The bridge forwards stdio traffic to a Decidealot container you already run.

openclaw skills install @psyb0t/decidealot
openclaw plugins install clawhub:@psyb0t/decidealot
