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 / Web (incl. Aspire): aspire-service-defaults, aspire-integration-testing
- Data: efcore-patterns, database-performance
- DI / config: dependency-injection-patterns, microsoft-extensions-configuration
- Testing: testcontainers-integration-tests, playwright-blazor-testing, snapshot-testing
