Use when editing code structure with text matching ambiguity, handling "old_string not unique" problems, or performing formatting-independent pattern matching across function signatures, method calls, and class structures

Use when creating new .NET projects with Clean Architecture, implementing CQRS without MediatR, setting up layered architecture with DDD, or validating architecture rules with ArchUnit tests

Use when building Model Context Protocol (MCP) servers in .NET, configuring tools, transports (SSE/stdio), JSON serialization for AOT, or testing MCP endpoints

Use when listing all methods, functions, or classes in a file, exploring unfamiliar code, getting API overviews, or deciding what to read selectively without loading entire files

Use when searching for files by name, pattern, or type in large directories, or building file lists for pipelines with other tools

Use when choosing interactively from search results, files, processes, or any command output with preview capabilities

Use when creating OpenAPI mock examples for Microcks, setting up request/response routing with dispatchers, or mapping request fields to mock responses

Use when converting existing .prompt.md or .instructions.md files to reusable SKILL.md format, before guessing structure or deciding what to keep/remove

Use when querying JSON files, filtering or transforming JSON data, or extracting specific fields from large JSON files without loading entire file contents (saves 80-95% context)

Use when querying YAML files, filtering or transforming configuration data, or extracting specific fields from large YAML files like docker-compose.yml or GitHub Actions workflows without loading entire files (saves 80-95% context)

Use when searching for text patterns across files, finding specific code locations, or getting lines with surrounding context in a single call

Use when configuring Git hooks in .NET projects before team commits occur, to enforce commit message standards and code formatting automatically

Use when setting up snip CLI token reduction hooks in a project, before first terminal commands are run

Use when viewing source files or documentation with syntax highlighting, previewing files with Git integration, or when enhanced readability would improve code review
