DotLightSkillset

A lightweight, curated Claude Code skillset for .NET developers.

Plugin identifier: dotlight-skillset

Combines three upstream MIT skill libraries into one opinionated bundle, with workflow overrides that fix the rough edges of "pure TDD" agent loops.

What it bundles

Workflow (18 skills) — customized fork of obra/superpowers plus four adapted skills from mattpocock/skills (grill-me, design-an-interface, grill-with-docs) and two from hsmejky/skills (improve-architecture, caveman): brainstorming → writing-plans → executing-plans → TDD → code review → finishing-branch, plus worktrees, systematic-debugging, parallel agents, skill authoring, doc-aware grilling (grill-with-docs), Ousterhout-style architecture review (improve-architecture), and explicit-trigger ultra-terse mode (caveman).
.NET patterns (26 skills) — curated fork of Aaronontheweb/dotnet-skills: C# standards, Minimal API design, DI, configuration, serialization, Aspire (4 skills — configuration, service-defaults, integration-testing, mcp-first for runtime debugging), OpenTelemetry, Testcontainers, Playwright (Blazor + CI caching), ILSpy decompilation, quality gates (slopwatch + CRAP). Plus dotlight-original rider-mcp-first — when JetBrains Rider MCP is attached, force semantic operations over filesystem Grep/Read for 50–90 % token savings on .NET exploration.
Specialized .NET agents (3) — dotnet-performance-analyst, dotnet-benchmark-designer, dotnet-concurrency-specialist. Use the Agent tool with subagent_type matching the agent name.

Superpowers drives the process, dotnet-skills supply the patterns, agents do focused diagnostic work.

Why this exists

Out-of-the-box Superpowers has two habits that hurt .NET projects:

TDD-first domain discovery. "Minimal code to pass" applied literally produces entities without relationships and invariants.
Text-based Socratic dialogue. Multiple-choice questions as plain-text lists, even in clients that render AskUserQuestion as clickable choice cards.

Fixed in modified SKILL.md files:

brainstorming — prefers AskUserQuestion over text multi-choice, caps questions at 5-8, enforces Domain Model as the first design section.
writing-plans — requires a ## Domain Model section derived from the design. If missing, loops back to brainstorming. Default exec sub-skill is executing-plans, not subagent-driven-development.
test-driven-development — domain model must exist in the plan before first RED-GREEN-REFACTOR. Calls out "test-cheating" (satisfying tests by violating invariants) as the #1 LLM-TDD failure mode.

What's deliberately excluded

From Superpowers: subagent-driven-development (too slow; prefer executing-plans)
From dotnet-skills (skills): all akka-* (5), aspire-mailpit-integration, mjml-email-templates, verify-email-snapshots, marketplace-publishing, skills-index-snippets
From dotnet-skills (agents): akka-net-specialist, docfx-specialist, roslyn-incremental-generator-specialist

For Akka.NET, Mailpit, or DocFX work, install the upstream dotnet-skills plugin alongside — they cooperate fine.

Companion plugins (recommended pairings)

DotLightSkillset focuses on the .NET workflow surface. For adjacent specialties, pair it with:

VoltAgent — voltagent-data-ai — specialist agents for data-heavy .NET work: postgres-pro, database-optimizer, data-engineer, ml-engineer, data-scientist. Particularly useful with TimescaleDB / EF Core / NHibernate projects that grow ML-adjacent.
playwright@claude-plugins-official — general Playwright MCP integration for non-Blazor SPA stacks (Vue/Vite, React, etc.). Dotlight only ships the Blazor-specific Playwright skill.

These work in parallel — no conflicts.

Who this is for

.NET developers using .NET 10, Aspire (or pure host builders), Minimal API, NHibernate or EF Core, Postgres / TimescaleDB, and Vue/Vite or Blazor frontends, who want the auto-review / brainstorming / planning flow from Superpowers without having the agent design the domain for them via TDD. If you also need Akka.NET, install the upstream dotnet-skills plugin alongside — DotLightSkillset is opinionated about which extensions live in scope.
