Can it help prevent security leaks?

Yes, it scans for public properties and missing JsonSerializable implementations that might accidentally expose sensitive data like password hashes or API tokens in JSON responses.

Does it work with Doctrine and other ORMs?

Specifically, it targets common ORM pitfalls such as proxy object serialization, lazy-loading triggers, and bidirectional relationship circularities common in Doctrine and Eloquent.

How does this skill improve PHP API performance?

It identifies 'silent' performance killers like N+1 queries triggered during the serialization phase and suggests replacing full entity hydration with faster scalar results or DTOs.

What kind of output does the skill provide?

It provides a detailed report including the severity of the issue, the exact file location, the performance impact, and a specific code fix to optimize the serialization logic.

API 开发

Analyzes PHP code to detect and resolve serialization performance bottlenecks, N+1 queries, and sensitive data exposure.

The check-serialization skill is a specialized diagnostic tool for PHP developers using Claude Code to audit their applications for inefficient data handling. It scans codebases for critical serialization issues such as N+1 query triggers during JSON encoding, massive object hydration overhead, and circular references that lead to runtime errors. By identifying missing JsonSerializable implementations and problematic binary data handling, it helps developers implement high-performance DTO patterns and secure API responses, ultimately reducing memory usage and response latency.
