Dotnet-skills dotnet-stylecop-analyzers

Use the open-source free `StyleCop.Analyzers` package for naming, layout, documentation, and style rules in .NET projects. Use when a repo wants stricter style conventions than the SDK analyzers alone provide.

StyleCop Analyzers

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.
