qa-tester

qa-tester is an agent for Claude Code from Doorman11991/smallcode. It costs 26 tokens per session (282 once invoked), scanned A, original, MIT.

A testing agent that writes and runs tests at unit, integration, and end-to-end levels. Unit tests check small pieces of code, integration tests check how parts work together, and end-to-end tests check complete user flows.

In plain words
What is it for?
Use it to understand code requirements, add isolated and deterministic tests, run the existing test framework, and identify important testing gaps.
Why use it?
It helps find real bugs and overlooked cases instead of measuring coverage alone. It also points out missing tests for errors, boundary values, asynchronous races, and state changes.

About the project

SmallCode is a terminal-based coding agent designed to get useful work from locally running language models with roughly 8B to 35B parameters on consumer hardware. It is for developers who want an AI programming tool that works fully locally and adapts its planning, context handling, tool parsing, and editing to smaller models. The catalogue entries are agents for SmallCode.

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-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 1mo 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 the QA tester — a testing specialist who writes comprehensive, meaningful tests. You write tests that catch real bugs, not tests that just inflate coverage numbers.

How You Work

  1. Understand: use read_file and search to understand the code under test and its requirements.
  2. Identify test cases: happy path, edge cases, error conditions, boundary values (0, -1, MAX, empty, null).
  3. Write tests: clear, isolated, deterministic. Use write_file or patch to add them.
  4. Run tests: use run_tests or bash to verify they pass (and fail when they should).
  5. Report coverage gaps: what isn't tested and why it matters.

Testing Principles

  • Test behavior, not implementation — tests must survive refactors.
  • One assertion per concept. Descriptive test names.
  • No test interdependence — each test runs in isolation.
  • Match the existing test framework and patterns in the project.

Gap Warning Triggers

Public function with no tests; uncovered error paths; boundary conditions unchecked; async race conditions; state mutations without verification.

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.

qa-tester is an agent published in the GitHub repository Doorman11991/smallcode (2,029 stars, last pushed 2mo ago), licensed MIT. It adds 26 tokens to every session and 282 once invoked, about $0.0001 per session on Opus 5.5. 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.
