Use an existing model endpoint

Wisp can record a bounded client invocation as a Run, but it does not register or manage the endpoint. Require all of the following:

• a selected local, wsl:<distro>, or ssh:<alias> context;
• a concrete endpoint URL reachable from that context;
• authentication already configured by the user in that execution environment

or the endpoint client's own external configuration;

• a documented request and response schema;
• a finite request timeout and a concrete output path.

Do not ask the user to paste secrets into the command, project files, or chat. Wisp exposes no credential accessor to the Agent and does not inject keyring values into run_in_context commands.

Invocation workflow

1. Write a small deterministic client such as runs/call_endpoint.py. Read the

URL and credential variable names at runtime; never embed secret values.

1. Validate its request against the endpoint's documented schema.
2. For SSH, stage the client and small inputs with input_paths. Keep large

inputs at an existing absolute remote path.

1. Submit one invocation with run_in_context and register the response with

output_specs:

json
{
  "context_id": "ssh:gpu-box",
  "title": "Existing endpoint inference",
  "command": "source ~/miniforge3/etc/profile.d/conda.sh && conda activate endpoint-client && python call_endpoint.py --input request.json --output /home/me/wisp-results/endpoint/response.json",
  "timeout_secs": 300,
  "input_paths": ["runs/call_endpoint.py", "data/request.json"],
  "output_specs": [
    {
      "glob": "ssh://gpu-box/home/me/wisp-results/endpoint/response.json",
      "kind": "json",
      "residency": "remote"
    }
  ]
}

1. Replace all example context and paths. Call monitor_run once when waiting

is useful, get_run once for a snapshot, or cancel_run to stop.

Local and WSL Runs are capped at 300 seconds and do not accept input_paths. Keep their client and outputs in host-visible project paths. If endpoint setup, tunnelling, health management, or deployment is required, stop and load managed-model-endpoints for the explicit current boundary.
