What it does
Fix Analyzer Bug is an agent skill from dotnet/roslynator, published by the product's own GitHub organization. Use when fixing a Roslynator analyzer false positive or false negative, RCS, RR, or CS/RCF regression, incorrect diagnostic reporting, or bug report citing a specific rule id — not when adding new rules.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/changelog-examples.md`).
It sits in Development, covering QA and bug reports. 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
- Fixing a Roslynator analyzer false positive
- CS/RCF regression
- Incorrect diagnostic reporting
- Bug report citing a specific rule id — not when adding new rules
Example prompts
- “/fix-analyzer-bug”
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:
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
Fix Analyzer Bug loads about 1.1k tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 59 tokens; SKILL.md has 327 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 327 words (~1,065 tokens).
“Reproduce in an existing test file, minimal code fix, changelog entry. Highest-frequency contributor task.”
