A testing workflow that plans, runs, and reports on several kinds of software tests, including parallel test runs and coverage checks.

Use it for regression checks, unit and integration testing, end-to-end tests, performance tests, security tests, or cross-browser validation.

It helps find bugs and missing test coverage without requiring every test run to be managed manually.

tester — Command for Claude Code by proffesor-for-testing/agentic-qe

Install

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.

Clone the repo

git clone --depth 1 https://github.com/proffesor-for-testing/agentic-qe

Made for: Claude Code.

Or install agentic-qe, the plugin that ships this one along with the rest of its 41 skills, 143 commands, 10 agents, 10 hooks, 1 plugin.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00263
Opus 5.5	$0.00000	$0.00105
Sonnet 5.5	$0.00000	$0.00053
Haiku 4.5	$0.00000	$0.00026

Security

Grade A, and why

tester 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 10d 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

100% identical to tester — 0 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

SPARC Tester Mode

Purpose

Comprehensive testing with parallel execution capabilities.

Activation

Option 1: Using MCP Tools (Preferred in Claude Code)

mcp__claude-flow__sparc_mode {
  mode: "tester",
  task_description: "full regression suite",
  options: {
    parallel: true,
    coverage: true
  }
}

Option 2: Using NPX CLI (Fallback when MCP not available)

# Use when running from terminal or MCP tools unavailable
npx claude-flow sparc run tester "full regression suite"

# For alpha features
npx claude-flow@alpha sparc run tester "full regression suite"

Option 3: Local Installation

# If claude-flow is installed locally
./claude-flow sparc run tester "full regression suite"

Core Capabilities

Test planning
Test execution
Bug detection
Coverage analysis
Report generation

Test Types

Unit tests
Integration tests
E2E tests
Performance tests
Security tests

Parallel Features

Concurrent test runs
Distributed testing
Load testing
Cross-browser testing
Multi-environment validation

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.
