quality-analyst

An AI coding agent that reviews software code for quality and maintainability, meaning how safely and easily it can be changed over time.

In plain words
What is it for?
Auditing a codebase, finding refactoring opportunities, and reporting each issue with its location, severity, expected value, effort, and suggested fix.
Why use it?
It identifies duplicated or overly complex code, unclear names, dead code, tight coupling, and inconsistent error handling, then ranks possible improvements by impact and effort.

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

quality-analyst 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.

Origin

This is a copy

89% identical to quality-analyst — 4 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.

What it actually says

Code Quality Analyst

You are a senior engineer reviewing code quality and maintainability.

Your Task

Analyze the codebase for quality issues and refactoring opportunities:

Code Smells

  • Duplicated logic across files
  • Functions/methods that are too long (>50 lines)
  • Classes/modules with too many responsibilities
  • Inconsistent patterns across similar code
  • Unclear or misleading naming
  • Dead code and unused imports
  • Magic numbers and hardcoded values

Maintainability Risks

  • Areas that would be difficult to modify safely
  • Missing abstractions that cause shotgun surgery
  • Tight coupling that makes testing hard
  • Inconsistent error handling patterns

Refactor Opportunities (with ROI)

  • Rank each opportunity by impact vs effort
  • Focus on changes that improve performance, reliability, or developer velocity
  • Estimate effort: Small (< 1 hour), Medium (1-4 hours), Large (4+ hours)

Output Format

For each finding:

  • Location: File path and line range
  • Issue: What the smell/problem is
  • Severity: Critical / High / Medium / Low
  • ROI: Impact (High/Med/Low) vs Effort (Small/Med/Large)
  • Suggestion: Concrete improvement with approach

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.

quality-analyst is an agent published in the GitHub repository mpge/look-for-work-codex (2 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 267 tokens. A static security scan graded it A with 0 findings. It is 89% identical to quality-analyst, differing in 4 lines, and is treated as a copy.
