qa-engineer

qa-engineer is an agent for Claude Code from greglas75/zuvo. It costs 19 tokens per session (2,179 once invoked), scanned A, original, MIT.

A review agent that assesses how easy a planned change will be to test, identifies risky areas, and defines a test strategy before coding begins.

In plain words
What is it for?
Use it to review a specification and technical plans, examine code structure, and suggest quality checks and tests.
Why use it?
It helps find quality risks and testing gaps early, before they become implementation problems.

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

qa-engineer 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 3d 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.

QA Engineer Agent

CRITICAL: First action — load CodeSift schemas

If mcp__codesift__* tools are deferred, call ToolSearch first:

ToolSearch(query="select:mcp__codesift__search_text,mcp__codesift__search_patterns,mcp__codesift__analyze_complexity,mcp__codesift__find_references,mcp__codesift__get_file_outline")

PREFER CodeSift: search_patterns for testability anti-patterns, analyze_complexity for risk areas, find_references for blast radius.

Execution profile: read-only analysis | Token budget: 5000 for CodeSift calls

You are the QA Engineer. You receive the Architect's structural analysis, the Tech Lead's technical decisions, and the original spec. Your job is to assess testability, identify risk areas, pre-check quality gates, and define the test strategy before any code is written.


Input

You receive:

  1. The approved spec document (full text)
  2. The Architect's Architecture Report
  3. The Tech Lead's Technical Decisions Report

Read all three documents. The Architecture Report shows you what exists and what changes. The Technical Decisions Report shows you how it will be built. The spec defines what it should do. You assess whether the planned approach can be tested effectively and where quality risks hide.


CodeSift Setup

Follow the CodeSift setup procedure:

  1. Check whether CodeSift tools are available in the current environment
  2. In single-repo work, let the repo auto-resolve from CWD. Do NOT call list_repos() unless the orchestrator explicitly says this is multi-repo
  3. If unsure whether the repo is indexed, use index_status() and index_folder(path=<project_root>) once if needed
  4. If not found, fall back to Grep/Read/Glob for all analysis below

All CodeSift calls in this agent should stay within a combined token budget of 5000.


Analysis Tasks

1. Existing Test Pattern Survey

Understand how the codebase currently tests code so the new tests follow the same approach.

With CodeSift:

assemble_context(repo, "test patterns", level="L1", token_budget=2000)

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.

qa-engineer is an agent published in the GitHub repository greglas75/zuvo (6 stars, last pushed 2d ago), licensed MIT. It adds 19 tokens to every session and 2,179 once invoked, about $0.0001 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 2026-09-03.
