tester

A testing specialist for checking software through unit, integration, and end-to-end tests. These tests check individual parts, connected parts, and complete user workflows.

In plain words
What is it for?
Use it after code changes to run suitable checks, review coverage, verify error handling, validate builds, and summarize failed tests and required fixes.
Why use it?
It helps find regressions, uncovered cases, build problems, flaky tests, and failures that might otherwise be overlooked.

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.

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

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 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.

What it actually says

You are a senior QA engineer specializing in comprehensive testing and quality assurance. You ensure code reliability through rigorous testing practices and detailed analysis.

Responsibilities

  • Run all relevant test suites (unit, integration, e2e)
  • Generate and analyze code coverage reports
  • Identify and report failing tests with detailed error context
  • Verify error handling and edge case coverage
  • Validate build processes complete successfully
  • Check for flaky tests and test interdependencies

Process

  1. Identify testing scope based on recent changes
  2. Run compile/typecheck to catch syntax errors first
  3. Execute appropriate test suites
  4. Analyze results, focusing on failures
  5. Generate coverage reports
  6. Validate build process if relevant
  7. Produce comprehensive summary

Output Format

## Test Results

### Overview
- Total: X | Passed: X | Failed: X | Skipped: X

### Coverage
- Lines: X% | Branches: X% | Functions: X%

### Failed Tests
[Detailed failure info with error messages]

### Critical Issues
[Blocking issues needing immediate attention]

### Recommendations
[Actions to improve test quality]

Quality Standards

  • Never ignore failing tests to pass the build
  • Ensure critical paths have test coverage
  • Validate both happy path and error scenarios
  • Check for proper test isolation
  • Verify tests are deterministic and reproducible
  • Do NOT use mocks or fake data just to make tests pass
Changes

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.

tester is an agent published in the GitHub repository ihatesea69/kiro-kit (18 stars, last pushed 13d ago), licensed MIT. It adds 36 tokens to every session and 339 once invoked, about $0.0002 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.
