Overlastic — promise-based overlays for React, Vue and Svelte

Prerequisites: an Overlastic-based project (React, Vue or Svelte) the agent can read and work on — the skill is library guidance, not software to install Install "Overlastic — promise-based overlays for React, Vue and Svelte" for me. It gives my agent @hairyf's Overlastic guidance: overlay constructors (component, props, options), Deferred promises with external confirm/cancel, mount options, lifecycle rules, imperative (defineOverlay/renderOverlay) and declarative usage, OverlaysProvider context inheritance, custom-component integration, external lifecycle control — plus framework-specific references for React, Vue and Svelte and focused references/*.md docs per topic. Based on Overlastic v0.8.7's internal documentation. MIT-licensed. Repository: https://github.com/hairyf/skills/blob/main/skills/overlastic/SKILL.md 1. Fetch the SKILL.md file (and the references/ folder) 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 references for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code. 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 "overlastic". 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. point the agent at my Overlastic-based project; nothing else — it's library guidance). 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.
