Invoke this skill to post or comment on Reddit (r/HeliumNetwork) about Helium Release Proposals. This is the Reddit posting skill — it creates new announcement threads and adds update comments to existing ones. ALWAYS invoke for: "post it", "announce it", "let people know", "send a reminder", "notify the community" when the context involves an HRP, release, vote, or feature. ALWAYS invoke when the user says "the vote is live", "voting is open", "vote went live", "multisig signed" — these mean it's time to post the vote-live reminder on Reddit. These phrases default to Reddit unless the user explicitly says Twitter, email, or blog. ALWAYS invoke when the user mentions Reddit, subreddit, r/HeliumNetwork, or "the thread" alongside any HRP or release content. ALWAYS invoke when someone wants to communicate a release, vote reminder, or feature update to the Helium community without naming a specific platform — Reddit is the default community channel. DO NOT invoke for: drafting blog posts, sending emails, posting on Twitter/X, reviewing PRs, creating release files, or just looking up a reddit-post-id.
