The non-interactive branch of maybeInstallCloudflareSkillsGlobally used logger.log (stdout) to print the Cloudflare agent skills banner. This contaminated the output of commands like `wrangler deploy --json | jq`, causing jq to fail with a parse error because the banner prefixed the JSON. Changed to logger.warn so the banner goes to stderr, leaving stdout clean for structured output consumers. Fixes cloudflare#14036.

There was a problem hiding this comment.
The general preference is that when we are in JSON output mode we do not render any such logs, rather than sending them to stderr.

The log has entirely been removed in #14162 so this PR is no longer applicable, sorry @matingathani 😓 |

Thanks @dario-piotrowicz — makes sense to close since #14162 removes the log entirely. Closing. |

Fixes #14036.
maybeInstallCloudflareSkillsGloballyusedlogger.log(stdout) for the non-interactive informational banner. When users pipe wrangler output (e.g.wrangler deploy --json | jq), the banner prefixes the JSON and causesjqto fail:The root cause: the non-interactive branch (
!isInteractive() && !ci.isCI) is exactly the shape of a scripted invocation from an operator shell. The banner is informational — it belongs on stderr like every other non-data message.Fix:
logger.log→logger.warnin the non-interactive branch ofmaybeInstallCloudflareSkillsGlobally.logger.warnroutes toconsole.warn(stderr), leaving stdout clean for JSON consumers. The interactive install path (line ~133) keepslogger.logsince that targets a TTY user.
