shifting-clinical-dates

Apply consistent per-patient date shifting in OpenMed that preserves intervals between events while satisfying HIPAA Safe Harbor's date rule. Use when the user needs to de-identify dates but keep temporal structure for research, shift all dates by the same offset per patient, preserve days-between-events for survival or longitudinal analysis, cap ages over 89, or strip everything but the year. Covers deidentify(method="shift_dates", date_shift_days=..., keep_year=...) and per-patient reproducible offsets via consistent=True, seed=.... Pairs with OpenMed deidentifying-clinical-text and auditing-safe-harbor-checklist.

add-localization

Add or update a language translation in the privacy policy generator. Trigger when user says: "add {language} translation", "add locale", "translate to {language}", "add localization for {language}", or when a user wants to contribute a new language.

build-parallelism

Guide for optimizing MSBuild build parallelism and multi-project scheduling. USE FOR: builds not utilizing all CPU cores, speeding up multi-project solutions, evaluating graph build mode (/graph), build time not improving with -m flag, understanding project dependency topology. Note: /maxcpucount default is 1 (sequential) — always use -m for parallel builds. Covers /maxcpucount, graph build for better scheduling and isolation, BuildInParallel on MSBuild task, reducing unnecessary ProjectReferences, solution filters (.slnf) for building subsets. DO NOT USE FOR: single-project builds, incremental build issues (use incremental-build), compilation slowness within a project (use build-perf-diagnostics), non-MSBuild build systems.

including-generated-files

Fix MSBuild targets that generate files during the build but those files are missing from compilation or output. USE FOR: generated source files not compiling (CS0246 for a type that should exist), custom build tasks that create files but they are invisible to subsequent targets, globs not capturing build-generated files because they expand at evaluation time before execution creates them, ensuring generated files are cleaned by the Clean target. Covers correct BeforeTargets timing (CoreCompile, BeforeBuild, AssignTargetPaths), adding to Compile/FileWrites item groups, using $(IntermediateOutputPath) instead of hardcoded obj/ paths. DO NOT USE FOR: C# source generators that already work via the Roslyn pipeline, T4 design-time generation that runs in Visual Studio, non-MSBuild build systems.

template-smart-defaults

Applies cross-parameter default rules when creating .NET projects with dotnet new, filling gaps consistently without overriding values the user set explicitly. USE FOR: choosing sensible defaults for related parameters during project creation, resolving cross-parameter interactions (AOT implies a compatible framework, auth implies HTTPS, controllers excludes minimal-API flags), explaining why a default was applied. DO NOT USE FOR: creating the project itself (use template-instantiation), finding or comparing templates (use template-discovery and template-comparison), authoring or validating custom templates (use template-authoring and template-validation).

migrate-static-to-wrapper

Replace existing static dependency call sites with a wrapper or built-in abstraction that already exists or is registered in DI. Codemod-style bulk replacement of DateTime.Now/UtcNow to TimeProvider, File.ReadAllText to IFileSystem, and similar, across a bounded scope (file, project, namespace), adding constructor injection to affected classes and updating their unit tests to use a test double. USE FOR: replace DateTime.UtcNow/DateTime.Now with TimeProvider and add the constructor parameter, migrate static call sites to a wrapper already in DI, bulk replace File.* with IFileSystem, scoped migration of statics in only certain files, migrate a service to TimeProvider and update its unit tests to a controllable/fake time source, update test doubles when migrating off static DateTime/File calls. DO NOT USE FOR: detecting statics (use detect-static-dependencies), creating or registering the wrapper when it does not exist yet (use generate-testability-wrappers), migrating between test frameworks.

property-patterns

MSBuild property definition patterns: conditional defaults, composition/concatenation, path normalization, trailing-slash handling, TFM detection helpers, and evaluation order. USE FOR: diagnosing and fixing property definition issues and shared-property anti-patterns in .props/.csproj; DefineConstants or NoWarn overwritten instead of appended; unconditional assignments that block project-level overrides; unquoted conditions that fail on empty properties; hardcoded paths that break cross-platform builds; setting overridable defaults; property evaluation order and last-write-wins semantics. DO NOT USE FOR: props vs targets placement (use directory-build-organization), item operations (use item-management), target structure (use target-authoring), general anti-patterns (use msbuild-antipatterns), non-MSBuild build systems.

worktree-manager

Create and manage Git worktrees for parallel development workflows. Use when multiple self-contained issues should NOT be fixed in a single branch, when human-Copilot iteration requires isolated environments with separate chat history and commits, or when parallel work items need independent build/test results. Triggers on requests involving branch isolation, work item separation, parallel development, or avoiding messy branch switching.
