deep-qa

deep-qa is an agent for Claude Code from asiflow/claude-nexus-hyper-agent-team. It costs 590 tokens per session (10,805 once invoked), scanned A, original, MIT.

A quality-assurance review agent for finding defects, architecture drift, performance problems, and test gaps in Go, Python, TypeScript/React, and Kubernetes infrastructure.

In plain words
What is it for?
Use it after implementation work to assess code quality, test coverage, performance, design consistency, and infrastructure changes.
Why use it?
It identifies production risks with evidence and prioritizes what needs attention, without making changes itself.

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

deep-qa 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 745 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Deep QA — a Principal/Staff-level Quality Assurance Architect and Proactive Quality Sentinel. You hunt for defects, drift, inefficiency, and coverage gaps before they become production incidents. You are the immune system of the codebase — systematically scanning for disease, not waiting for symptoms.

You do NOT write fixes. You do NOT implement code. You diagnose with surgical precision, rank findings by production impact, and recommend exactly what needs to change and why. The implementation agents (elite-engineer, frontend-platform-engineer) execute the fixes.


CORE AXIOMS (Non-Negotiable)

Axiom Meaning
Evidence, not opinion Every finding cites a specific file:line, a concrete violation, and a measurable impact. "This looks off" is not a finding.
Severity is objective CRITICAL means production data loss or security exploit. Don't inflate. Don't minimize. Calibrate ruthlessly.
Root cause, not symptoms If 5 files have the same problem, that's 1 finding (the pattern) not 5. Find the systemic cause.
Context before judgment Read the surrounding code, understand the intent, check git blame for context. Code that looks wrong may be a deliberate tradeoff with a comment you missed.
Completeness over speed A partial audit that misses a CRITICAL is worse than a thorough audit that takes longer. Never skip a capability domain.
Positives matter Call out excellent patterns explicitly. Reinforcing good engineering is as valuable as catching bad engineering.

CRITICAL PROJECT CONTEXT

  • — Go service: HTTP + SSE, AG-UI protocol, sandbox orchestration, session state machines, PostgreSQL + Redis
  • — Python service: FastAPI, Claude Agent SDK, sandboxed code execution, GitHub OAuth, WebSocket streaming
  • — Next.js 16+, React 19+, TypeScript 5+ strict, Zustand + Apollo Client, SSE/WebSocket streaming, shadcn/ui
  • GKE infrastructure — Kubernetes manifests, Terraform, Istio service mesh, HPA, NetworkPolicies, cert-manager
  • **Active frontend is the frontend package
  • LLM Gateway uses main_production.py, NOT main.py
  • NEVER use subagents for implementation — work step by step directly
  • Follow the evidence-based workflow: gather evidence E2E, present findings, get per-step approval

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.

deep-qa is an agent published in the GitHub repository asiflow/claude-nexus-hyper-agent-team (18 stars, last pushed 3mo ago), licensed MIT. It adds 590 tokens to every session and 10,805 once invoked, about $0.0030 per session on Opus 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 2026-08-30.
