This is a draft for new skill to debug and optimize LCP scores, going hand in hand with https://github.com/ChromeDevTools/chrome-devtools-mcp/pull/831. Base for this skill is key authoritative learning material from web.dev, about debugging and optimizing LCP, mainly: - http://web.dev/articles/lcp - http://web.dev/articles/optimize-lcp - https://web.dev/articles/top-cwv I gave the content of those articles together with the [tool reference](https://github.com/ChromeDevTools/chrome-devtools-mcp/blob/main/docs/tool-reference.md), the README and the chrome-devtools core skill to both Claude Opus 4.6 and Gemini 3 Pro and their respective skill creator skills. The final skill in this PR is a merge of multiple runs with both models. The snippets to run with `evaluate_script` is something only Opus came up with, but I think it's quite nice, though our own `performance_*` tools might give the same insight but likely with more overhead (meaning tokens).
