name: probe-compute-environment

description: Inspect a registered execution server before compute planning and interpret its persisted capability profile. Use when a server is added, when the user clicks Probe, before enabling an unfamiliar SSH/WSL resource, or when deciding whether GPU, sudo/root, a scheduler, Python, R, conda, mamba, or environment modules are available.

# Probe compute environment

Use Wisp's environment Probe action. It performs bounded, read-only checks and

- stores the result on the `ExecutionContext`; do not replace it with an ad-hoc

- SSH discovery loop.

+ stores the result on the `ExecutionContext`. An SSH probe batches every check

+ into one authenticated session; do not replace it with an ad-hoc SSH discovery

+ loop. Batch SSH uses `IdentitiesOnly=yes`; users relying on a non-default

+ ssh-agent key must configure its `IdentityFile` in Wisp or SSH config.

After probing:

1. Treat persisted capabilities as the server contract until it is probed again.

2. Treat `gpu_summary: null` as **no usable GPU**. Plan CPU work and never add

CUDA/GPU flags speculatively.

3. Treat `privilege: unprivileged` as **no root or passwordless sudo**. Do not

use `sudo`, system package managers, or system paths; prefer user-space

environments, modules, containers already installed by the administrator,

or ask the user for an administrator-installed dependency.

4. Use a detected scheduler rather than running long work on a login node.

5. Use the recorded interpreter paths and environment managers. Do not assume

`python`, `Rscript`, conda, mamba, or modulecmd exists when absent.

- 6. If the probe failed or is stale relative to a server change, probe again

+ 6. If the probe failed, inspect the saved error and ask the user to check the

+ connection before manually probing again. Never loop or automatically retry

+ an SSH probe. If it is merely stale relative to a server change, probe again

before submitting work.
