AI Coding Skills for Scala

Browse the best AI coding skills for Scala in 2026, Scala 3 syntax, Cats Effect / ZIO IO patterns, Akka actors, ScalaTest / MUnit tests, and sbt builds. Works with every major AI coding tool.

Short answer

The best AI coding skills for Scala are skills-hub's `code-review`, `unit-test` (ScalaTest + MUnit), `api-scaffold` (http4s / ZIO HTTP / Akka HTTP), `db-schema` (Slick / Doobie), and `secure`. Portable across Claude Code, Cursor, Codex CLI, Copilot, and Cline.

Scala 3 + Cats Effect / ZIO is the dominant production stack in 2026, with Akka still common in larger enterprises. The skills below detect your Scala stack (Scala 3 syntax, given/using, extension methods, opaque types) and emit idiomatic effect-typed code, not the Java-in-Scala-syntax patterns the model learned from old samples.

  16. 16authoring-github-workflows

    Author and review GitHub Actions workflow YAML safely so syntactically-valid YAML can't ship a workflow that GitHub Actions refuses to run. USE FOR: editing, adding, or reviewing any file under .github/workflows/, writing run-name/name/if/env/run values that contain ${{ }} expressions, diagnosing a run that fails with 'This run likely failed because of a workflow file issue' and no jobs starting, deciding when a workflow scalar must be quoted, validating workflows with actionlint. DO NOT USE FOR: authoring application YAML unrelated to GitHub Actions, Azure Pipelines, GitLab CI, or non-workflow YAML. SCOPE: this skill covers *syntactic/structural* correctness of workflow YAML (quoting, parsing, actionlint); for *semantic and functional* workflow design (what a workflow should do, agentic-workflow behavior), see .github/agents/agentic-workflows.agent.md — the two are complementary. INVOKES: actionlint (downloaded pinned binary) plus git/grep for inspection.

Frequently asked questions

Do AI skills know Scala 3 syntax?

Yes, modern skills default to Scala 3 (significant indentation OR braces, given/using, enum, opaque types, extension methods, .nn for null safety) and detect Scala 2 fallback when project pins it.

Can AI write Cats Effect / ZIO code?

Yes. The api-scaffold skill detects which effect type the project uses and emits properly typed IO/ZIO with Resource for acquisition, Fiber for concurrency, and Ref/Deferred for shared state.

What's the best AI tool for Scala?

IntelliJ with the Scala plugin is the deepest IDE option. Claude Code's JetBrains plugin gets that depth; Cursor with Metals is the best VS Code-shaped experience.

Do AI skills handle Akka actor patterns?

Yes, the api-scaffold skill emits Behavior[Message] with proper supervision strategies, ActorContext, and timer scheduling. It also flags Akka classic patterns when found and proposes typed Akka migrations.
