MCPGateway: Skill for Codex

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

mcaf-dotnet-cloc is a skill for Codex from managedcode/MCPGateway. It costs 64 tokens per session (1,382 once invoked), scanned B, a copy of mcaf-dotnet-cloc, MIT.

A setup for using cloc, a free tool that counts source lines, programming languages, and changes between code versions.

In plain words
What is it for?
Measuring C# and solution footprint, comparing branches or commits, and producing code-size reports for local work or CI.
Why use it?
It turns questions about a .NET codebase's size and composition into repeatable measurements without treating line count as developer productivity.

Skill for Codex

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

This is managedcode/MCPGateway's own configuration. It tells Codex how to work on MCPGateway 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 MCPGateway 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 B, and why

mcaf-dotnet-cloc scanned grade B with 1 finding 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

MCAF: .NET cloc

Trigger On

  • the repo wants cloc
  • the team needs repeatable LOC, language, or branch diff statistics for a .NET repo
  • the user asks about C# codebase size, solution composition, or code-count deltas between refs

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

  • judging developer productivity from raw LOC
  • replacing behavioral verification, architecture review, or complexity analysis
  • counting generated or vendored files without an explicit reason

Inputs

  • the nearest AGENTS.md
  • target repository, solution, project, or subtree
  • the question being answered: footprint, composition, diff, or trend

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. Choose the counting mode deliberately:
    • --vcs=git for repo-respecting counts
    • path-based counting for bounded folders
    • --git --diff BASE HEAD for change deltas
  2. Prefer .NET-relevant views first:
    • C# footprint
    • test versus production footprint
    • solution language mix such as C#, Razor, XML, JSON, YAML, and MSBuild files
  3. Exclude noise before trusting the numbers:
    • bin
    • obj
    • .git
    • vendored or generated folders when they are not part of the decision
  4. Use machine-readable output when the numbers feed docs, CI, or follow-up automation:
    • --json
    • --csv
    • --yaml
    • --md
  5. Treat cloc as a sizing and comparison tool, not as evidence that the design is good.
  6. When using diff mode, compare named refs that match the review question:
    • origin/main..HEAD
    • release branch versus main
    • before and after a refactor
  7. After any code cleanup based on cloc findings, run the repo's normal quality pass.

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.
