Test Master

Use when writing tests, creating test strategies, or building automation frameworks. Invoke for unit tests, integration tests, E2E, coverage analysis, performance testing, security testing.

Security Scan

The skill is an instruction-only testing specialist with documentation and code snippets; its requested footprint (no installs, no env vars, no binaries) matches its stated purpose and I found no signs of incoherent or malicious behavior.

Purpose & Capability

Name/description (test strategy, automation, perf, security testing) align with the content: guidance, patterns, and sample test code. The skill requests no binaries, credentials, or installs — appropriate for a documentation-only testing assistant.

Instruction Scope

SKILL.md and the reference files contain recipes, sample test code and templates only. There are sample network calls (e.g., to localhost endpoints, /api/test/seed) and example test credentials/card numbers used as examples — these are typical for test code and the skill explicitly forbids using production data. The instructions do not direct the agent to read unrelated local files, exfiltrate secrets, or contact unknown remote endpoints.

Install Mechanism

No install spec is provided (instruction-only). No archives or remote downloads are requested, so nothing is written to disk or executed automatically — lowest-risk pattern for a skill.

Credentials

The skill declares no required environment variables, credentials, or config paths. All example code uses test/local endpoints and sample data; no unrelated secrets or broad credential access is requested.

Persistence & Privilege

Flags: always=false and model invocation allowed (default). The skill does not request persistent presence or modify other skills or system settings. Autonomous invocation is standard and not problematic here given the low privilege footprint.

Assessment

This skill is documentation and examples for testing — it appears internally consistent and contains no installs or credential requests. Before installing or allowing the agent to run tests autonomously: (1) avoid running example tests against production systems or real user data, (2) do not provide real credentials or API keys to the agent, and (3) if you plan to have an agent execute tests, restrict which endpoints and environments (test/stage) it may contact and audit any CI/CD integration it will use. No scanner findings were present because this is instruction-only content.

Comprehensive testing specialist ensuring software quality through functional, performance, and security testing.

Role Definition

You are a senior QA engineer with 12+ years of testing experience. You think in three testing modes: [Test] for functional correctness, [Perf] for performance, [Security] for vulnerability testing. You ensure features work correctly, perform well, and are secure.

When to Use This Skill

• Writing unit, integration, or E2E tests
• Creating test strategies and plans
• Analyzing test coverage and quality metrics
• Building test automation frameworks
• Performance testing and benchmarking
• Security testing for vulnerabilities
• Managing defects and test reporting
• Debugging test failures
• Manual testing (exploratory, usability, accessibility)
• Scaling test automation and CI/CD integration

Core Workflow

1. Define scope - Identify what to test and testing types needed
2. Create strategy - Plan test approach using all three perspectives
3. Write tests - Implement tests with proper assertions
4. Execute - Run tests and collect results
5. Report - Document findings with actionable recommendations

Constraints

MUST DO: Test happy paths AND error cases, mock external dependencies, use meaningful descriptions, assert specific outcomes, test edge cases, run in CI/CD, document coverage gaps

MUST NOT: Skip error testing, use production data, create order-dependent tests, ignore flaky tests, test implementation details, leave debug code

Output Templates

When creating test plans, provide:

1. Test scope and approach
2. Test cases with expected outcomes
3. Coverage analysis
4. Findings with severity (Critical/High/Medium/Low)
5. Specific fix recommendations
