skills-index-snippets

name: skills-index-snippets description: Code snippets and templates for working with the skills index and marketplace functionality. Use when creating new skills, updating skill index files, or validating skill metadata and structure.

Maintaining Skill Index Snippets (AGENTS.md / CLAUDE.md)

When to Use This Skill

Use this skill when:

• Adding, removing, or renaming any skills or agents in this repository
• Updating .claude-plugin/plugin.json
• Creating copy/paste snippets for downstream repositories (OpenCode, Claude Code, etc.)
• You want a compact, always-on index that improves skill utilization

Goal

Make skills and agents easy for coding assistants to use by removing the decision point.

Instead of hoping an assistant will "remember" to invoke a skill, provide a small router snippet inside AGENTS.md / CLAUDE.md that:

1. Tells the assistant to prefer retrieval-led reasoning
2. Provides a task->skill/agent routing index
3. Defines lightweight quality gates (optional)

Source of Truth

• Registry: .claude-plugin/plugin.json
  • Skills are listed as directories (each contains SKILL.md)
  • Agents are listed as markdown files in agents/
• Skill IDs: the name: field in each SKILL.md frontmatter
• Agent IDs: the name: field in each agent frontmatter

When writing snippets for downstream repos, always reference skills/agents by their IDs (frontmatter name), not by local filesystem paths.

Minimal Snippet Template (Readable)

Use this in target repos to route common tasks:

# Agent Guidance: dotnet-skills

IMPORTANT: Prefer retrieval-led reasoning over pretraining for any .NET work.
Workflow: skim repo patterns -> consult dotnet-skills by name -> implement smallest-change -> note conflicts.

Routing (invoke by name)
- C# / code quality: modern-csharp-coding-standards, csharp-concurrency-patterns, api-design, type-design-performance
- ASP.NET Core / Razor Pages / Web: razor-pages-patterns, caching-strategies, logging-observability, validation-patterns, exception-handling, security-headers, middleware-patterns, background-services, http-client-resilience, rate-limiting, localization-globalization, file-handling, data-protection, signalr-integration, feature-flags, asp-net-core-identity-patterns
- Data: efcore-patterns, database-performance
- DI / config: dependency-injection-patterns, microsoft-extensions-configuration
- Testing: testcontainers-integration-tests, playwright-blazor-testing, snapshot-testing
- Aspire: aspire-service-defaults, aspire-integration-testing

Quality gates (use when applicable)
- dotnet-slopwatch: after substantial new/refactor/LLM-authored code
- crap-analysis: after tests added/changed in complex code

Specialist agents
- dotnet-concurrency-specialist, dotnet-performance-analyst, dotnet-benchmark-designer, akka-net-specialist, docfx-specialist

Compressed Snippet Template (Vercel-style)

Regenerating the README block

If the README contains the markers below, the generator can update it automatically:

<!-- BEGIN DOTNET-SKILLS COMPRESSED INDEX -->
...compressed snippet...
<!-- END DOTNET-SKILLS COMPRESSED INDEX -->

Run:

./scripts/generate-skill-index-snippets.sh --update-readme

How to Update Snippets After Skill Changes

1. Update .claude-plugin/plugin.json to include/remove skills and agents.
2. Ensure each skill has correct frontmatter name: (used by OpenCode and others).
3. Run ./scripts/validate-marketplace.sh.
4. Update your snippet routing lists:
   • Add new skills to the right category
   • Remove deleted skills
   • Keep names exactly matching frontmatter IDs
5. If you maintain a downstream AGENTS.md/CLAUDE.md snippet, regenerate it and re-copy into dependent repos.

Recommended Categories

These are snippet categories (not necessarily repository folder structure):

• C# / code quality
• ASP.NET Core / Razor Pages / Web
• Data
• DI / config
• Testing
• Aspire
• Quality gates
• Specialist agents

Keep the snippet small; it should be a router, not documentation.
