Skill instructions
Performance WebUI's value proposition is speed and low memory usage. Every change to core Rust crates, @microsoft/webui-framework, or @microsoft/webui-router must be evaluated through two lenses: throughput (how fast) and memory (how little). Server memory is not cheap. Client memory is not unlimited. Every allocation that can be avoided is a win on both sides. Use this skill when modifying any performance-sensitive code across the stack. Rust - speed rules These apply to webui-handler, webui-state, webui-expressions, webui-parser, webui-protocol, and webui-ffi. 1. No format!() in writer output. Use sequential writer.write() calls. format! allocates a temporary String every invocation. 2. No .tostring() on Cow. Write Cow<str directly to avoid defeating zero-copy. 3. No collect::<Vec<() on splits. Iterate path.split('.') directly. Collecting allocates a Vec for sequential access. 4. No redundant scans. Use firstpart.len() == path.len() instead of path.contains('.'). 5. No String::from(c
