What it does
Roslyn Query is an agent skill from NikiforovAll/claude-code-rules. Query .NET/C codebases using Roslyn AST analysis via dotnet run file. Use for tracing data flow, auditing API usage, finding pattern violations, or ad-hoc codebase queries.
Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/roslyn-api.md` and `references/templates.md`).
It works with .NET and C#. The repository describes itself as: Learn practical techniques to enhance your AI-assisted development workflow with Claude Code. The licence is Apache-2.0.
When your agent uses it
- Tracing data flow
- Auditing API usage
- Finding pattern violations
- Ad-hoc codebase queries
Example prompts
- “/roslyn-query”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 281c063. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
dotnet
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Roslyn Query loads about 957 tokens when it runs, and up to ~6.1k if it reads all its reference files. Until then it costs about 47 tokens; SKILL.md has 372 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Roslyn Query
Query .NET/C# codebases using Roslyn AST analysis scripts executed via dotnet run file.cs.
Before generating scripts, load the handbook-dotnet:dotnet-run-file skill for execution conventions and directive syntax.
When to Use
- Trace data flow from sources to sinks (taint analysis)
- Audit all assignments to specific properties
- Find all callers of a method
- Find all implementations of an interface
- Detect pattern violations (empty catches, missing sanitizers, etc.)
- Architecture validation (layer violations)
- Ad-hoc codebase structural queries
Analysis Tiers
Tier 1: Syntax-Only (fast, no compilation)
Uses CSharpSyntaxTree.ParseText() — parses files individually, no solution loading.
Best for:
- Property assignment audits (
x.Content = ...) - Empty catch block detection
- Naming convention checks
- Cyclomatic complexity
- Magic number/string detection
- Method size metrics
- Pattern matching on code structure
Tier 2: Semantic (needs project/solution)
Uses MSBuildWorkspace — loads project, resolves types, enables cross-file analysis.
Best for:
- Find all callers of a method (
SymbolFinder.FindCallersAsync) - Find interface implementations (
SymbolFinder.FindImplementationsAsync) - Find method overrides (
SymbolFinder.FindOverridesAsync) - Type dependency graphs
- Full data flow analysis (
SemanticModel.AnalyzeDataFlow)
Instructions
Step 1: Determine analysis type
Based on the user's request, choose the appropriate template from references/templates.md. If no template fits, compose a custom script using the patterns documented there.
Show full SKILL.md (187 more words)Show less
Step 2: Generate the script
Create a .cs file in a scripts/ directory (or temp location) using dotnet run file.cs format with #:package directives.
For syntax-only analysis:
#:package Microsoft.CodeAnalysis.CSharp@4.*For semantic analysis, additionally:
#:package Microsoft.CodeAnalysis.CSharp.Workspaces@4.*
#:package Microsoft.CodeAnalysis.Workspaces.MSBuild@4.*
#:package Microsoft.Build.Locator@1.*
#:property DisableMSBuildAssemblyCopyCheck=trueNote:
DisableMSBuildAssemblyCopyCheck=truesuppresses the MSBL001 build error that requiresExcludeAssets="runtime"on MSBuild packages — an attribute#:packagedirectives can't express. Safe for throwaway analysis scripts.
.slnxnot supported: Roslyn 4.xMSBuildWorkspaceonly supports.sln, not.slnx. UseOpenProjectAsyncwith a.csprojinstead — transitive project references are loaded automatically.
Step 3: Script conventions
- Accept target directory/path via
args[0], default toDirectory.GetCurrentDirectory() - Use
Path.GetRelativePath()for output paths - Print structured output: file:line, description, context
- Use color: green for safe, yellow for warnings, red for violations
- Exit code 0 = clean, 1 = findings
Step 4: Execute
dotnet run scripts/my-analysis.cs -- <target-path>Step 5: Interpret results
Analyze the output. For taint analysis, categorize findings:
- Safe — trusted source (code-generated, AI output, literal null)
- Already sanitized — sanitizer call deeper in call chain (syntax-only false positive)
- Needs investigation — external input, user-authored content
- Violation — clear miss that should be fixed
