Google Sheets Skill for Muse

Prerequisites: the gws CLI installed, a Google account with Sheets access, and a one-time OAuth flow (the shared auth SKILL.md is generated by running `gws generate-skills`). No paid API — Google Sheets API free tier. Install "Google Sheets Skill for Muse" for me. Read and write Google Sheets from Muse via the gws CLI: read cell ranges, append rows (single or bulk), create spreadsheets, and full spreadsheets API operations — with dedicated +read (read-only) and +append helper skills. Repository: https://github.com/googleworkspace/cli 1. Locate the gws-sheets skill and its +read and +append helper skills in the repository; fetch their SKILL.md files (and any helper files) into a temporary folder and summarize what each does in one or two sentences. 2. Safety check: review the SKILL.md files 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 the SKILL.md files and their helper files into the agent's skills directory, in a folder named "gws-sheets". 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. install the gws CLI, run `gws generate-skills` for auth, and complete the Google OAuth flow). 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.
