Please test this email validation regex ^([a-zA-Z0-9._%+-]+)+@([a-zA-Z0-9.-]+)+\.[A-Za-z]{2,}$ for correctness, ReDoS risk, and memory usage, then provide a safer rewritten version with explanations.Returns validation results, catastrophic backtracking analysis, risk notes, and a safer, more efficient replacement regex.
I have a regex for parsing logs: ^(.*),(ERROR|WARN|INFO),(.*)$. Please evaluate its performance and matching accuracy on large text, and rewrite it into a more stable version.
Outputs performance findings, mismatch risks, optimization rationale, and a regex better suited for production use.
Based on the requirement "match usernames 6 to 20 characters long that must contain both letters and numbers," generate candidate regexes, test each for correctness, performance, and safety, and recommend the best version.
Provides validation feedback for multiple candidate regexes, compares pros and cons, and recommends a final safe pattern.
Test, explain, validate, and optimize regular expressions for text-processing tasks.
Get context-aware coding rules, development guidance, and AI-curated advice.
Run multi-model reviews for code changes, PRs, and risky edits.
Choose regex first, then add LLMs for low-confidence parsing edge cases.
Detect prompt injection, look up CVEs, and assess version impact.
Run website health audits for security, performance, email setup, and link issues.
