dotPilot: Skill for Codex

.codex/skills/mcaf-dotnet-quality-ci/SKILL.md

mcaf-dotnet-quality-ci is a skill for Codex from managedcode/dotPilot. It costs 71 tokens per session (1,555 once invoked), scanned A, a copy of quality-ci, MIT.

A workflow for setting up or improving automated quality checks for .NET projects. It covers formatting, configuration rules, built-in and third-party analyzers, test coverage, mutation testing, architecture tests, and security scans.

In plain words
What is it for?
Use it to define a .NET quality stack in project instructions, documentation, or CI pipelines, including editor settings, warning policies, analyzers, coverage, mutation testing, architecture checks, and security scanning.
Why use it?
It helps teams decide which checks belong in their automated build and document those choices consistently. This catches quality issues before code is merged or released.

Skill for Codex

Written for Codex: installed under .codex/. Also seen: mentions AGENTS.md.

This is managedcode/dotPilot's own configuration. It tells Codex how to work on dotPilot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything dotPilot configures →

Reuse

Borrowing it

Nothing to install: this file belongs to managedcode/dotPilot. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

mcaf-dotnet-quality-ci 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 1mo 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.

MCAF: .NET Quality CI

Trigger On

  • adding or tightening .NET code-quality gates in CI
  • choosing analyzers, coverage, mutation, or architecture-test tooling for a .NET repo
  • standardizing .editorconfig, dotnet format, and warning policy

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

  • non-.NET repositories
  • generic CI/CD guidance with no .NET quality stack decisions
  • framework-specific test authoring with no quality-gate change

Inputs

  • the nearest AGENTS.md
  • the current repo-root .editorconfig and MSBuild props
  • the current CI workflow and package references
  • the active test runner model: VSTest or Microsoft.Testing.Platform

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. Start with the repo-native baseline:
    • repo-root .editorconfig
    • dotnet format --verify-no-changes
    • SDK analyzers with explicit EnableNETAnalyzers, AnalysisLevel, and warning policy
  2. Add third-party analyzers only where they close a real gap:
    • StyleCopAnalyzers
    • Roslynator
    • Meziantou.Analyzer
    • framework analyzers such as xUnit, MSTest, or TUnit analyzers
  3. Separate quality gates by purpose:
    • formatting and style
    • correctness and static analysis
    • coverage and reports
    • architecture rules
    • security scanning
    • mutation testing
  4. For complexity, use a composite approach:
    • CA1502 thresholding
    • maintainability limits in AGENTS.md
    • architecture tests
    • coverage and mutation where risk justifies it
  5. Make ownership explicit in AGENTS.md and CI:
    • which command formats
    • which command analyzes
    • which command measures coverage
    • which runner model the tests use
  6. After any .NET code change, the repo's quality pass must be runnable by agents:
    • format
    • build
    • analyze
    • focused tests
    • broader tests
    • coverage and report generation when configured
    • extra configured gates only when the repo actually enabled them
  7. Route tool-specific setup through dedicated skills where possible:
    • mcaf-dotnet-format
    • mcaf-dotnet-code-analysis
    • mcaf-dotnet-analyzer-config
    • analyzer-pack skills such as mcaf-dotnet-stylecop-analyzers, mcaf-dotnet-roslynator, and mcaf-dotnet-meziantou-analyzer
    • coverage/reporting skills such as mcaf-dotnet-coverlet and mcaf-dotnet-reportgenerator
    • architecture/security skills such as mcaf-dotnet-netarchtest, mcaf-dotnet-archunitnet, and mcaf-dotnet-codeql
  8. Avoid overlapping tools with conflicting ownership. If you add an opinionated formatter, define whether it replaces or complements dotnet format.

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.
