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:
- Tells the assistant to prefer retrieval-led reasoning
- Provides a task->skill/agent routing index
- 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/
- Skills are listed as directories (each contains
- Skill IDs: the
name:field in eachSKILL.mdfrontmatter - 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

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
- Update
.claude-plugin/plugin.jsonto include/remove skills and agents. - Ensure each skill has correct frontmatter
name:(used by OpenCode and others). - Run
./scripts/validate-marketplace.sh. - Update your snippet routing lists:
- Add new skills to the right category
- Remove deleted skills
- Keep names exactly matching frontmatter IDs
- If you maintain a downstream
AGENTS.md/CLAUDE.mdsnippet, 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.
