Mcaf Dotnet Stylecop Analyzers

MCAF: .NET StyleCopAnalyzers

Trigger On

• the repo wants StyleCop.Analyzers
• naming, layout, or documentation style needs stronger enforcement
• the team needs stylecop.json guidance

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 intentionally rely only on SDK analyzers
• repos where StyleCop overlaps too heavily with an existing style package and no consolidation is planned

Inputs

• the nearest AGENTS.md
• current .editorconfig
• any existing stylecop.json

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 StyleCop.Analyzers only if the repo wants its opinionated style rules.
2. Keep severity in the root .editorconfig.
3. Use stylecop.json only for StyleCop-specific behavioral options.
4. Prefer one checked-in stylecop.json per repo unless a project genuinely needs its own behavior.
5. Avoid rule duplication with SDK analyzers or other analyzer packs when possible.

Bootstrap When Missing

If StyleCop.Analyzers is not configured yet:

1. Detect current state:
   • rg -n "StyleCop\\.Analyzers|stylecop\\.json" -g '*.csproj' -g 'stylecop.json' .
2. Add package to the intended scope:
   • dotnet add PROJECT.csproj package StyleCop.Analyzers
3. Keep severity in root .editorconfig and use stylecop.json only for StyleCop-specific behavior.
4. Prevent overlap with existing analyzer packs by defining ownership.
5. Run dotnet build SOLUTION_OR_PROJECT and return status: configured or status: improved.
6. If the repo intentionally uses SDK analyzers only, return status: not_applicable.

Deliver

• explicit StyleCop package setup
• repo-owned StyleCop rule configuration
• clear split between root .editorconfig and stylecop.json

Validate

• StyleCop severity is versioned in repo config
• stylecop.json is used only where it adds value

Ralph Loop

Use the Ralph Loop for every task, including docs, architecture, testing, and tooling work.

1. Plan first (mandatory):
   • analyze current state
   • define target outcome, constraints, and risks
   • write a detailed execution plan
   • list final validation skills to run at the end, with order and reason
2. Execute one planned step and produce a concrete delta.
3. Review the result and capture findings with actionable next fixes.
4. Apply fixes in small batches and rerun the relevant checks or review steps.
5. Update the plan after each iteration.
6. Repeat until outcomes are acceptable or only explicit exceptions remain.
7. If a dependency is missing, bootstrap it or return status: not_applicable with explicit reason and fallback path.

Required Result Format

• status: complete | clean | improved | configured | not_applicable | blocked
• plan: concise plan and current iteration step
• actions_taken: concrete changes made
• validation_skills: final skills run, or skipped with reasons
• verification: commands, checks, or review evidence summary
• remaining: top unresolved items or none

For setup-only requests with no execution, return status: configured and exact next commands.
