The upstream SKILL.md names no author, and the upstream repository now sits under the personal account yalishevant with an MIT licence naming Anton Yalyshev. - The JetBrains/skills README disclaims the catalogue as provided for demonstration and educational purposes only and asks you to test each skill before relying on it. - The upstream repository moved: https://api.github.com/repos/Kotlin/kotlin-backend-agent-skills now returns yalishevant/kotlin-backend-agent-skills, a personal account (checked 2026-10-13). The pins and the MIT licence are unchanged. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - integration-resilience-engineer/SKILL.md (JetBrains mirror) - upstream .agents/skills/integration-resilience-engineer/SKILL.md - upstream LICENSE - JetBrains/skills README mirror policy - https://github.com/Kotlin/kotlin-backend-agent-skills (answers HTTP 301 to yalishevant/kotlin-backend-agent-skills) - mirror SKILL.md diffed against the upstream SKILL.md at fd0ed521d22efd28221d532c9abab97af0b9bf0e ### Our findings - A diff against the upstream SKILL.md at fd0ed521d22efd28221d532c9abab97af0b9bf0e shows the mirror adds four frontmatter lines (metadata, short-description, author: Kotlin, source) and nothing else; the upstream file has no author field. agents/openai.yaml is identical in both. - The mirror README states every skill keeps an exact metadata.source link to its upstream path and that the snapshot is JetBrains-filtered and JetBrains-verified. - The boundary nuances separate outbox from inbox patterns: each solves a different half of reliability, and neither covers both publish and consume idempotency. - Upstream health: https://github.com/Kotlin/kotlin-backend-agent-skills, which the mirror’s metadata.source and README name, now answers HTTP 301 to yalishevant/kotlin-backend-agent-skills, a personal account (https://api.github.com/repos/Kotlin/kotlin-backend-agent-skills returns full_name yalishevant/kotlin-backend-agent-skills, owner type User). fd0ed521d22efd28221d532c9abab97af0b9bf0e is still that repository’s head, and its LICENSE (MIT, copyright 2026 Anton Yalyshev) is unchanged (checked 2026-10-13). ### Not established by this review - No integration was designed or load-tested with this skill. - The Spring-specific settings referenced by the rules were not compiled or run. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Add a skill to your workflow.
