dotPilot: Skill for Codex

.codex/skills/mcaf-dotnet-format/SKILL.md

mcaf-dotnet-format is a skill for Codex from managedcode/dotPilot. It costs 57 tokens per session (959 once invoked), scanned A, a copy of dotnet-format, MIT.

A setup for dotnet format, the .NET command-line tool that formats code and applies supported analyzer fixes using .editorconfig rules.

In plain words
What is it for?
Use it to format a solution or project, run narrower whitespace or style checks, and use --verify-no-changes in CI.
Why use it?
It gives developers and CI one repeatable way to check formatting and detect files that would change.

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 →

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-format 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.

Origin

MCAF: .NET dotnet format

Trigger On

  • the repo uses dotnet format
  • you need a CI-safe formatting check for .NET
  • the repo wants .editorconfig-driven style enforcement

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

  • repositories that intentionally use CSharpier as the only formatter
  • analyzer strategy with no formatting command change

Inputs

  • the nearest AGENTS.md
  • the solution or project path
  • the current .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. Prefer the SDK-provided dotnet format command instead of inventing custom format scripts.
  2. Start with verify mode in CI: dotnet format TARGET --verify-no-changes.
  3. Use narrower subcommands only when the repo needs them:
    • whitespace
    • style
    • analyzers
  4. Keep .editorconfig as the source of truth for style preferences.
  5. If the repo also uses CSharpier, document which tool owns which file types or rules.

Bootstrap When Missing

If dotnet format is requested but not available yet:

  1. Detect current state:
    • dotnet --info
    • dotnet format --version
  2. Treat dotnet format as SDK-provided, not as a separate repo-local tool by default.
  3. If the command is missing, install or upgrade to a supported .NET SDK, then recheck dotnet format --version.
  4. Add explicit local and CI commands to AGENTS.md, usually:
    • dotnet format TARGET --verify-no-changes
  5. Run the chosen command once and return status: configured or status: improved.
  6. If the repo intentionally uses only CSharpier for formatting ownership, return status: not_applicable.

What ships with it

1 file 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.
