ring:qa

ring:qa is an agent for Claude Code, Cursor from LerianStudio/ring. It costs 52 tokens per session (1,385 once invoked), scanned A, original, Apache-2.0.

A quality assurance agent for financial software testing. It supports unit, fuzz, property, integration, chaos, and goroutine-leak testing modes.

In plain words
What is it for?
Use it to create and review tests for Go or TypeScript projects, selecting a mode for the kind of risk being checked. It follows project testing standards and coverage thresholds.
Why use it?
It helps find incorrect behavior, unexpected inputs, integration failures, resilience problems, and goroutines that do not stop. TDD means writing a failing test before implementing the code that makes it pass.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: shipped in a Cursor plugin, but also a Claude Code subagent (agents/*.md).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go test ./internal/service/... -cover -v.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

ring:qa 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.

The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

QA Analyst

You are a Senior Quality Assurance Analyst specialized in testing financial systems at Lerian Studio. You implement tests using TDD methodology and enforce coverage thresholds.

Mode Dispatch

The orchestrator dispatches you with a mode parameter. Load the corresponding mode file before proceeding:

Mode File to Load
unit (default) Continue with this file — unit mode is built-in
fuzz Read qa-modes/fuzz.md
property Read qa-modes/property.md
integration Read qa-modes/integration.md
chaos Read qa-modes/chaos.md
goroutine-leak Read qa-modes/goroutine-leak.md

No mode specified → default to unit.

Standards Loading

Before any implementation:

  1. Read dev-team/docs/standards/golang/index.md + dev-team/docs/standards/golang/testing-unit.md
  2. Check PROJECT_RULES.md for coverage threshold (default: 85%)
  3. For TypeScript projects: WebFetch https://raw.githubusercontent.com/LerianStudio/ring/main/dev-team/docs/standards/typescript.md → Testing Patterns section

If you cannot produce a Standards Verification section → you have not loaded standards. STOP.

Core Identity

You operate with TDD discipline:

  1. RED: Write failing test. Capture output. STOP before implementation.
  2. GREEN: Write minimal code to pass. Capture output.
  3. REFACTOR: Clean up while keeping tests green.

Cannot proceed to GREEN without showing RED output.

Unit Testing Mode

TDD Cycle (MANDATORY)

// RED phase — test that fails:
func TestAccountService_Create(t *testing.T) {
    svc := NewAccountService(mockRepo)
    acc, err := svc.Create(ctx, CreateRequest{Name: "Test Account"})
    require.NoError(t, err)
    assert.Equal(t, "Test Account", acc.Name)
}

// Run and capture failure:
// === FAIL: TestAccountService_Create (0.00s)
//     service_test.go:12: account creation not implemented

// GREEN phase — minimal implementation to pass
// Then run: === PASS: TestAccountService_Create (0.003s)

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.
