Weights & Biases

Operate Weights & Biases through your OOMOL-connected account. This skill calls the wandb connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

Assume the user has already installed the oo CLI, signed in, and connected Weights & Biases. Do not run oo auth login or open the connection URL proactively — just run the action. Fall back to First-time setup only when a command actually fails with an auth or connection error.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

oo connector schema "wandb" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

oo connector run "wandb" --action "<action_name>" --data '<json>' --json

--data takes a JSON object string or @path/to/file.json; omit it to send {}.
The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action’s live schema with oo connector schema to get its authoritative input fields.

get_artifact_details — Get metadata, lineage, and optionally files for a W&B artifact version.
get_run_history — Retrieve sampled time-series metric history for a W&B run.
infer_trace_schema — Sample classic Weave traces to discover field paths, types, and frequent values. [write]

query_wandb — Run a read-only GraphQL query against W&B experiment data with bounded pagination.
query_weave_traces — Query classic Weave traces with filters, ordering, selected columns, cost data, feedback, and detail-level controls.
resolve_trace_roots — Resolve the root spans for a batch of classic Weave trace IDs.
search_docs — Search the official W&B documentation for relevant guidance and examples.
summarize_evaluation — Aggregate classic Weave evaluation results for a project or named evaluation.

Safety

Untagged actions are reads (get / list / search) — safe to run directly.
Actions tagged [write] change Weights & Biases state — confirm the exact payload and effect with the user before running.
Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux

irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell

Not signed in / authentication error — sign in to your OOMOL account once:
```
oo auth login
```
scope_missing / credential_expired / app_not_ready / app_not_found — Weights & Biases is not connected, or the connection expired or lacks a scope. Connect once (auth type: API key) at:
```
https://console.oomol.com/app-connections?provider=wandb
```
HTTP 402 / OOMOL_INSUFFICIENT_CREDIT — billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.
