A skill for configuring .NET maintainability checks and code metrics. These checks can flag methods with high cyclomatic complexity, which means many possible paths, and code with difficult structure or excessive coupling.

It helps identify overly complex methods, set maintainability and coupling limits, and plan refactoring or CI checks around those limits.

It helps turn concerns about hard-to-maintain code into explicit thresholds and checks that can be used during development or in continuous integration.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00047	$0.01013
Opus 5.5	$0.00019	$0.00405
Sonnet 5.5	$0.00009	$0.00203
Haiku 4.5	$0.00005	$0.00101

Security

Grade A, and why

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 19d 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

91% identical to complexity — 8 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

Read the nearest AGENTS.md and confirm scope and constraints.
Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
Return the Required Result Format with concrete artifacts and verification evidence.

Workflow

Start with the built-in maintainability analyzers before reaching for non-standard tooling.
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
Keep rule severity in the root .editorconfig.
Keep metric thresholds in a checked-in CodeMetricsConfig.txt added as AdditionalFiles.
Pair analyzer findings with MCAF maintainability limits in AGENTS.md.

Bootstrap When Missing

If complexity thresholds are not configured yet:

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

complexity is a skill published in the GitHub repository managedcode/Orleans.RateLimiting (30 stars, last pushed 11d ago), licensed MIT. It adds 47 tokens to every session and 1,013 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to complexity, differing in 8 lines, and is treated as a copy.
