dotnet-complexity

dotnet-complexity is a skill for Claude Code, Codex from Postpartum-genushyacinthus29/dotnet-skills. It costs 50 tokens per session (1,031 once invoked), scanned A, a copy of complexity, MIT.

A guide for using built-in .NET maintainability checks and code metrics to identify overly complex or tightly coupled code.

In plain words
What is it for?
Use it to review cyclomatic complexity, maintainability index, and class coupling, including rules such as CA1502, CA1505, and CA1506.
Why use it?
It turns concerns about hard-to-maintain code into measurable checks and optional CI thresholds.

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

dotnet-complexity 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 11d 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

This is a copy

92% identical to complexity — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

.NET Complexity Review

Trigger On

  • the team wants to find overly complex methods
  • cyclomatic complexity thresholds are needed in CI
  • maintainability metrics or coupling thresholds need to be configured

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

  • formatting-only work
  • generic analyzer setup with no complexity policy change

Inputs

  • the nearest AGENTS.md
  • current analyzer settings
  • current maintainability limits

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 built-in maintainability analyzers before reaching for non-standard tooling.
  2. Use these rules deliberately:
    • CA1502 for excessive cyclomatic complexity in methods
    • CA1505 for low maintainability index
    • CA1506 for excessive class coupling
    • CA1501 when inheritance depth is also part of the design problem
  3. Keep rule severity in the root .editorconfig.
  4. Keep metric thresholds in a checked-in CodeMetricsConfig.txt added as AdditionalFiles.
  5. Pair analyzer findings with MCAF maintainability limits in AGENTS.md.

Bootstrap When Missing

If complexity thresholds are not configured yet:

  1. Detect current state:
    • rg -n "CA1501|CA1502|CA1505|CA1506|CodeMetricsConfig" -g '.editorconfig' -g '*.csproj' -g 'Directory.Build.*' .
    • rg --files -g 'CodeMetricsConfig.txt'
  2. Add severity entries for CA1502, CA1505, CA1506, and CA1501 in root .editorconfig.
  3. Add checked-in CodeMetricsConfig.txt and include it as AdditionalFiles in project props.
  4. Keep maintainability limits aligned with AGENTS.md.
  5. Run dotnet build SOLUTION_OR_PROJECT and return status: configured or status: improved.
  6. If policy relies only on AGENTS.md limits with no analyzer gate by design, return status: not_applicable.

What ships with it

3 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.

dotnet-complexity is a skill published in the GitHub repository Postpartum-genushyacinthus29/dotnet-skills (10 stars, last pushed today), licensed MIT. It adds 50 tokens to every session and 1,031 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to complexity, differing in 12 lines, and is treated as a copy.
