GSAP: Timelines

Prerequisites: a JavaScript project with the `gsap` npm package installed (`npm install gsap` — all plugins are free since Webflow's acquisition, no membership or auth token needed) Install "GSAP: Timelines" for me. Give my agent the official GSAP timeline reference — position parameter, labels, nesting, playback controls Repository: https://github.com/greensock/gsap-skills/blob/main/skills/gsap-timeline/SKILL.md 1. Fetch the SKILL.md file for the greensock-gsap-timeline skill from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md 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 into the agent's skills directory, in a folder named "greensock-gsap-timeline". 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. `npm install gsap`). 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. Never ask me to paste secrets in chat — credentials go through the secure vault or environment variables. If anything looks off, stop and ask me.
