Buttondown Connector for Muse

Prerequisites: A Buttondown API key (Settings > API), kept in your Muse's secure vault (never paste secrets here). Note: email-create drafts by default — sending to the whole list (--send) always needs your explicit confirmation; subscriber-add also needs confirmation. Reading needs none. Buttondown has a free plan. No GitHub account needed unless listed here. Install "Buttondown Connector for Muse" for me. A Muse agent skill that reads and writes your Buttondown newsletter: list subscribers and emails, add subscribers, create email drafts. Repository: https://github.com/bluman1/muse-connectors/tree/main/connectors/buttondown 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "buttondown". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. save my Buttondown API key in the vault). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
