The Agent Skills Directory

Dependency Management: The skill guides users through updating project dependencies in Maven and Gradle. It transitions projects from the legacy cn.idev.excel group to the official Apache-hosted org.apache.fesod artifacts, which is a standard and expected refactoring process during a software migration.
Refactoring Guardrails: Phase 2x provides explicit "Scope guardrails" designed to prevent accidental regressions. These instructions advise the agent to limit replacements to import statements and static call sites while protecting business literals, headers, and documentation from mechanical rewrites.
Legacy Namespace Support: The skill correctly identifies and handles common legacy namespaces (cn.idev.excel and org.apache.fesod.excel), ensuring that partially migrated projects are correctly aligned with the final org.apache.fesod.sheet structure.
Encoding Safety: Phase 5 includes recommendations for maintaining UTF-8 encoding and handling character mapping issues, which helps prevent corruption of non-ASCII characters in source files during the replacement process.
No Executable Payload: The skill is composed entirely of markdown instructions. It does not include any scripts, executable files, or network-enabled tools, which minimizes the security risk associated with its execution environment.
