meziantou-analyzer

Meziantou.Analyzer

Trigger On

• the repo uses or wants Meziantou.Analyzer
• the team wants one analyzer pack that covers design, usage, security, performance, and style

Value

• produce a concrete project delta: code, docs, config, tests, CI, or review artifact
• reduce ambiguity through explicit planning, verification, and final validation skills
• leave reusable project context so future tasks are faster and safer

Do Not Use For

• repos that already enforce an overlapping analyzer baseline and do not want extra diagnostics
• formatting-only work

Inputs

• the nearest AGENTS.md
• current analyzer packages
• .editorconfig

Quick Start

1. Read the nearest AGENTS.md and confirm scope and constraints.
2. Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
3. Return the Required Result Format with concrete artifacts and verification evidence.

Workflow

1. Add Meziantou.Analyzer when the repo wants broader rules than the SDK baseline.
2. Keep rule severity in the repo-root .editorconfig.
3. Review overlaps with SDK analyzers and Roslynator before mass-enabling everything as errors.

Bootstrap When Missing

If Meziantou.Analyzer is not configured yet:

1. Detect current state:
   • rg -n "Meziantou\\.Analyzer" -g '*.csproj' .
2. Add the package to the intended scope (project-level or shared props strategy):
   • dotnet add PROJECT.csproj package Meziantou.Analyzer
3. Set severity in root .editorconfig for the enabled MAxxxx rules.
4. Keep overlap with SDK analyzers and Roslynator explicit to avoid duplicate noise.
5. Run dotnet build SOLUTION_OR_PROJECT and return status: configured or status: improved.
6. If the repo intentionally keeps a smaller analyzer surface, return status: not_applicable.

Deliver

• explicit Meziantou package setup
• repo-owned severity and warning policy

Validate

• the added rules are understood by the team
• CI runs stay actionable instead of noisy
