Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00025 | $0.00168 |
| Opus 5.5 | $0.00010 | $0.00067 |
| Sonnet 5.5 | $0.00005 | $0.00034 |
| Haiku 4.5 | $0.00003 | $0.00017 |
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 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.
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
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.

drin-code-complexity-auditor is a skill published in the GitHub repository pedrol-cmd/brain-drin (12 stars, last pushed 6mo ago), licensed MIT. It adds 25 tokens to every session and 168 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
