The OpenRewrite `MigrateToJSpecify` recipe\nautomates the common cases (javax, Jakarta, JetBrains, Micrometer, Micronaut); the rest are a short\nmanual mapping. See [references/annotation-migration.md](references/annotation-migration.md).\n\n## Incremental adoption for large codebases\n\nFlipping every package to `@NullMarked` at once is impractical on a large or legacy codebase.\n`@NullUnmarked` lets you enforce NullAway on a growing perimeter while the rest stays untouched.\nBecause the build above enables `OnlyNullMarked` mode, packages without `@NullMarked` are simply\nignored — so adoption is driven purely by adding markers, one package at a time. Strategies,\nprogress tracking, common NullAway errors, and redundant null-guard removal are in\n[references/incremental-adoption.md](references/incremental-adoption.md).\n\n## Kotlin interop (optional)\n\nIf the project also has Kotlin sources, the Kotlin compiler (K2) reads JSpecify annotations on Java\nAPIs and surfaces accurate nullability instead of platform types. See\n[references/kotlin-interop.md](references/kotlin-interop.md).\n","tagline":"Use this skill when asked to perform any of the following actions in a Java project: - To add jspecify support - To prevent NullPointerExceptions - To better handle Nullability This skill will add jspecify dependency, configure Maven or Gradle build to automatically use jspecify ","category":"research","tags":["agent-skill"],"author":"sivaprasadreddy","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"sivaprasadreddy/sivalabs-agent-skills","creatorName":"sivaprasadreddy","creatorUrl":"https://github.com/sivaprasadreddy","sourceUrl":"https://github.com/sivaprasadreddy/sivalabs-agent-skills/tree/main/skills/jspecify","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/sivaprasadreddy-jspecify-skill#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
