Validator Deprecated Pydantic

The validator deprecation tool analyzes user-provided inputs to determine if a given Pydantic validator or configuration is deprecated in the target version. It targets developers migrating from Pydantic v1 to v2, code maintainers, and CI teams during refactors. For teams, this reduces risk and effort in large-scale migrations by providing actionable guidance.
Conceptually, it uses a deprecation matrix derived from release notes to decide if a feature is deprecated in the specified library_version. It accepts inputs such as library_version, feature_name, and optional code_snippet, and returns structured outputs suitable for automation and reporting.
Unique value: the tool differentiates itself by offering migration steps tailored to the specific feature, including recommended alternatives and concrete code-change guidance. It works without executing runtime code, relying on static analysis and documented deprecations.
Core features include a) deprecation flag, b) since_version indicator, c) recommended alternative, d) migration plan, e) exportable JSON outputs for CI. Use cases include preparing a migration plan for a v1→v2 upgrade, auditing a codebase for deprecated validators, and generating automated reports for release notes.
