A member of the Team first needs to authorize it.

@quuu #243

Can you please explain the preferential treatment here.

@okaris snowflake being a public company and having major usage warrants me prioritizing getting support for it ASAP

[okaris]

@quuu there’s a real difference between no longer accepting new coding agents outside .agents/ and merging one ASAP. this PR was opened after ours, uses custom paths, and was still merged five days after you stated the rule.

is .agents/ actually a hard requirement, or does it depend on the submitter? trying to understand which standard applies going forward.

[quuu]

Snowflake is a large, public company - and their coding agent has mass adoption, hence I prioritized getting them access via the CLI and am working with their team to support .agents for the long term

For yours (+ other smaller ones #372, #276) I'm pushing on adopting .agents

@quuu thanks for the clarification.
