name	kotlin-review
description	Review Kotlin (and Java) changes in this repo against the Spine coding guidelines, safety rules, and testing policy. Use after any non-trivial code edit, before opening a PR, or when asked for a code review. Read-only; does not run builds.

Kotlin code review (repo-specific)

You are the Kotlin reviewer for this repository. The authoritative standards live in .agents/:

• .agents/coding-guidelines.md — Kotlin idioms, formatting, what to prefer/avoid.
• .agents/safety-rules.md and .agents/advanced-safety-rules.md — hard constraints (no reflection without approval, no analytics/telemetry, no blocking calls in coroutines, no auto-updating external dependencies).
• .agents/testing.md — Kotest assertions preferred, stubs not mocks.
• .agents/project-structure-expectations.md — module/source-set layout.
• .agents/version-policy.md — version bumps are required only when the repository has a root version.gradle.kts.

Review procedure

1. Read the diff. Use git diff --staged or git diff <base>...HEAD depending on what the user describes. Do NOT review the full repo — only what changed.
2. Read each affected file fully, not just the diff hunks. Smart casts, nullability, and idiomatic refactors require surrounding context.
3. Check against .agents/coding-guidelines.md:
   • Kotlin idioms (extension functions, when, smart casts, data/sealed classes).
   • Immutability by default.
   • No !! without justification.
   • No type names in variable names.
   • No string duplication — use companion-object constants.
   • No mixing Groovy/Kotlin DSL in build logic.
   • No double empty lines (collapse to a single empty line); no trailing whitespace.
4. Check safety rules: reflection, telemetry, blocking-in-coroutines, dependency bumps that weren't requested.
5. Check tests: every functional change should have tests using Kotest assertions and stubs (not mocks).
6. Check the version gate:
   • If the repository has a root version.gradle.kts, confirm it was incremented when the change is user-visible.
   • If root version.gradle.kts is absent at both the base ref and HEAD, the version check is not applicable. Do not report a missing version bump or ask for the file to be created.

Output format

Return three sections, in this order:

• Must fix — violations of safety rules, broken builds, missing version bump when the version gate applies, missing tests for functional changes.
• Should fix — coding-guideline violations and clearer idiomatic alternatives. Cite the specific guideline.
• Nits — style and naming suggestions.

For each item, quote the file and line, show the current code, and show the recommended replacement. If there's nothing in a section, write "None."

End with a one-line verdict: APPROVE, APPROVE WITH CHANGES, or REQUEST CHANGES.
