drin-code-complexity-auditor

drin-code-complexity-auditor is a skill for Claude Code from pedrol-cmd/brain-drin. It costs 25 tokens per session (168 once invoked), scanned A, original, MIT.

A workflow for measuring how difficult code is to understand and maintain. It examines branching paths, nesting depth, function size, and the effort required for a person to read the code.

In plain words
What is it for?
Use it to audit a codebase, find overly complex functions, and decide where to split logic or remove deeply nested code.
Why use it?
It helps locate code that is risky to change or hard to review. The results can guide developers toward smaller functions and clearer logic.

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

drin-code-complexity-auditor 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 2d 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.

What it actually says

Code Complexity Auditor

Purpose

To ensure the codebase remains maintainable and easy to understand as it grows.

Metrics

  • Cyclomatic Complexity: Number of linear paths through code.
  • Cognitive Complexity: How hard it is for a human to read.
  • Lines of Code (LoC) per Function: Keeping it modular.
  • Depth of Nesting: Reducing "Pyramid" code.

Rules

  • Break down any function with complexity > 10.
  • Prefer explicit logic over "Clever" one-liners.

subagents:

  • code-reviewer
  • code-architect
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.
