What it does
Add Analyzer is an agent skill from dotnet/roslynator, published by the product's own GitHub organization. Use when adding a new RCS diagnostic in roslynator (RCS0 formatting, RCS1 general, RCS9 code-analysis), wiring roslynator EditorConfig options, or when docs say CHANGELOG.md, XunitDiagnosticVerifier, or analyzers-testing.md — those are wrong for in-repo contribution.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/analyzer-schema.md`, `references/config-options.md` and `references/implementation.md`).
It sits in Development, covering Changelog and release notes. It works with C# and .NET. The repository describes itself as: Roslynator is a set of code analysis tools for C, powered by Roslyn.
When your agent uses it
- Adding a new RCS diagnostic in roslynator (RCS0 formatting
- RCS9 code-analysis)
- Wiring roslynator EditorConfig options
- Docs say CHANGELOG.md
Example prompts
- “/add-analyzer”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Confirm metadata parameters (hard gate above).
- Add entry; schema in references/analyzer-schema.md. Use docs-site analyzer-metadata, not Template.Analyzers.xml`.
- Optional config option before codegen — references/config-options.md.
- Codegen from tools/ (required cwd — see Common Mistakes).
- Implement analyzer, code fix (if confirmed), tests — references/implementation.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 167f434. 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:
pwshdotnet
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
josefpihrt.github.io
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
Add Analyzer loads about 1.3k tokens when it runs, and up to ~3.7k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 407 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 407 words (~1,262 tokens).
“Roslynator analyzers are metadata-driven: edit Analyzers.xml, codegen, implement analyzer + code fix, test, changelog. New analyzers never set — only IsEnabledByDefault`.”
