stylecop-analyzers

stylecop-analyzers is a skill for Claude Code, Codex from managedcode/dotnet-skills. It costs 142 tokens per session (1,053 once invoked), scanned A, original, MIT.

A .NET analyzer package for enforcing naming, layout, documentation, and other C# style rules.

In plain words
What is it for?
Use it to add stricter style checks to .NET projects and configure their severity in .editorconfig, with optional StyleCop-specific settings.
Why use it?
Teams can otherwise apply style conventions inconsistently across files and contributors. These rules make the chosen conventions checkable in the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

stylecop-analyzers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
