Migrates code, prompts, and API calls from Claude Sonnet 4.0/4.5 or Opus 4.1 to Opus 4.5, updating model strings on Anthropic, AWS, GCP, Azure platforms.
Breaks plans, specs, or PRDs into thin vertical-slice issues on the project issue tracker using tracer bullets. Useful for converting high-level work into grabbable implementation tickets.

核心定位：从业务需求 → Timefold 领域模型 + 约束 + 求解器配置的方法论 + 能力目录。
不是"场景查找表"。遇到任何新排程需求（教学排课、车辆路径、人员排班、半导体生产排程、项目调度 ...）都走同一套 6 步法。
使用本 skill 当用户请求涉及：
拿到需求先做 6 步抽象，不要直接写代码。详见 references/modeling-methodology.md。
@PlanningEntity）@PlanningVariable / @PlanningListVariable）@ValueRangeProvider 位置）@InverseRelationShadowVariable / @PreviousElementShadowVariable / @ShadowVariable + @ShadowSources / @CascadingUpdateShadowVariable）每一步对应的能力都在 references/capability-catalog.md。
完整细节见 references/capability-catalog.md。
| 建模需求 | Timefold 能力 | 能力目录章节 |
|---|---|---|
| 实体从值域选 1 个 | @PlanningVariable | §1 |
| 实体排成有序列表（路径 / 工序链 / 装载） | @PlanningListVariable + 配套 shadow | §2 |

| 派生字段（到达时间、总成本） | @ShadowVariable(supplierName) + @ShadowSources | §3.4 |
| 沿列表级联派生 | @CascadingUpdateShadowVariable | §3.5 |
| 允许部分实体不分配 | allowsUnassigned=true / allowsUnassignedValues=true | §4 |
| 冻结已确定的排程 | @PlanningPin / @PlanningPinToIndex | §5 |
| 动态值域（按实体过滤） | 实体级 @ValueRangeProvider | §6 |

写 ConstraintStream 前先查 references/constraint-cookbook.md：
forEachUniquePair + Joiners.overlappingforEach + filter 前置.endTime vs 当前.startTimegroupBy + sum + filtergroupBy + count + filterifNotExists / forEachIncludingUnassignedifExists / filterConstraintCollectors.loadBalance 或平方惩罚toConnectedRanges / toConnectedTemporalRanges见 references/solver-tuning.md：
spent-limit + unimproved-spent-limitenvironment-mode=REPRODUCIBLE + random-seedenablePreviewFeature（Diversified Late Acceptance / Neighborhoods / Solution Diff）timefold-solver-spring-boot-starter + timefold.solver.* propertiestimefold-solver-quarkus + quarkus.timefold.solver.* propertiesSolverFactory.create(new SolverConfig()...)骨架可直接复用：assets/skeleton/（pom.xml + Entity/Value/Solution/ConstraintProvider/App/Test 全套）。
见 references/testing-patterns.md：
ConstraintVerifier 单测（违反 N 次 / 违反 0 次 / 边界）SolutionManager.analyze| 错误 | 修正 |
|---|---|
派生字段标 @PlanningVariable | 改 @ShadowVariable / @CascadingUpdateShadowVariable |
用 sourceVariableName / variableListenerClass（deprecated since 1.27） | 用 supplierName + @ShadowSources |
用 @PlanningVariable(graphType=CHAINED)（deprecated since 1.31） | 用 @PlanningListVariable |
@ValueRangeProvider 返回值依赖规划变量 | 只能依赖 problem facts |
| 时间直接当 PlanningVariable | 时间通常是 shadow，变量是序列位置或离散时段 |
| supplier 里做 IO / 改字段 | supplier 必须纯函数 |
| 一个方法堆多条约束 | 一条业务规则 = 一个方法 = 一个 .asConstraint("名") |
对齐 timefold-solver 1.33+（group ai.timefold.solver；旧版 org.optaplanner.* 已迁移）。Java 17+ required。
