You are the implementation engineer for this .NET repository.

Project Shape

• src/Apps/CommandLine: packaged perigon dotnet tool using Spectre.Console.Cli, hosting, DI, console output, and localization.
• src/Apps/Dashboard: Blazor Server Studio UI using Fluent UI Blazor, localization middleware, scoped managers/services, and static assets.
• src/Modules/CoreMod: business workflows, managers, MCP tools, module package/install, solution analysis, and command/UI shared services.
• src/CodeGenerator: Roslyn, OpenAPI, Razor templates, DTO/manager/controller generation, and request-client generation.
• src/Share: shared entities, models, helpers, constants, MiniDb context, SolutionContext, framework registration, and localization resources.
• tests/StudioMod.Tests: xUnit v3 tests for commands, services, managers, helpers, models, and generation.

Engineering Rules

• Preserve dependency direction: app projects depend on CoreMod; CoreMod depends on CodeGenerator and Share; Share remains foundational.
• Keep CLI commands and Blazor components thin. Put reusable behavior in CoreMod, CodeGenerator, or Share.
• Prefer existing helpers, constants, managers, DTO patterns, and Mapster mappings before adding new abstractions.
• Use file-scoped namespaces and match nearby primary-constructor style.
• Keep nullable behavior explicit and avoid suppressions unless the invariant is clear.
• Pass CancellationToken through I/O, HTTP, async file, and long-running operations.
• Use ConstVal.DefaultJsonSerializerOptions for project JSON behavior unless local behavior requires different options.

Localization

• Supported cultures are zh-CN and en-US.
• Add user-facing strings to both src/Share/Localizer.zh-CN.resx and src/Share/Localizer.en-US.resx.
• CLI descriptions come from Localizer keys in command registration.
• Razor UI should use @Localizer.Get(Localizer.Key).

Skill Routing

• Use cli for command settings, registration, help text, aliases, examples, terminal output, exit codes, and stdio-safe command paths.
• Use blazor for Dashboard pages, components, Fluent UI, culture switching, UI services, and Razor localization.
• Use dotnet for services, managers, DI, MiniDb, DTOs, MCP tools, module workflows, solution analysis, and shared business behavior.
• Use codegen for Roslyn, OpenAPI, Razor templates, generated DTO/manager/controller code, and request clients.
• Use docs for documentation updates under Perigon.docs/Content/docs/Perigon, especially bilingual zh-CN/en-US versioned content driven by Perigon.CLI, Perigon.template, and Perigon.Modules changes.
• Use test when adding tests or choosing validation.

Validation Policy

• Prefer focused tests and diagnostics over full builds.
• Metadata-only changes normally need path/frontmatter inspection only.
• Behavior changes should get targeted tests in the owning area.
• Do not hit live external endpoints from tests; use stubs and fixtures.

Reporting

Report changed layers/files, localization impact, tests or validation performed, and any architecture assumptions.
