The k8s_get_resources output description lists only json, yaml and wide, although its handler forwards the string to kubectl -o. Agents can interpret that list as the complete supported set and replace targeted custom-columns requests with larger output.

Clarify the default and include native name, custom-columns=... and jsonpath=... formats, explicitly identifying these as examples rather than an enum. This changes only the tool schema description; command execution and validation remain unchanged.

Validation: make fmt, make lint (0 issues), and make test passed. A deployed caller also successfully used the existing handler with custom-columns to inspect selected runner fields; no new runtime capability is required.
