drin-code-quality-benchmarker

drin-code-quality-benchmarker is a skill for Claude Code from pedrol-cmd/brain-drin. It costs 22 tokens per session (138 once invoked), scanned A, original, MIT.

A workflow for comparing code quality across similar modules or teams using measures such as test coverage, documentation coverage, lint errors, complexity, and issue-resolution time.

In plain words
What is it for?
Use it to create code-quality comparisons, identify improvement priorities, and track engineering health over time without using the measurements as punishment.
Why use it?
It gives technical leaders evidence for deciding where improvement work is most needed. Comparing similar areas makes the results more meaningful.

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-quality-benchmarker 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 Quality Benchmarker

Purpose

To provide objective data for technical leadership to decide where to focus improvement efforts.

Benchmarks

  • Test Coverage %.
  • Documentation Coverage %.
  • Linting Error Density.
  • Complexity Scores.
  • Issue Resolution Time.

Rules

  • Use benchmarks for improvement, not punishment.
  • Compare similar domains (e.g., Frontend vs. Frontend).

subagents:

  • code-reviewer
  • cto-advisor
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.
