What it does

Quinn is an agent skill from sickn33/agentic-awesome-skills. Proves the system works by writing and executing comprehensive test suites.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Test generation. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

  • Tasks that involve Test generation

Example prompts

  • “Use the quinn skill to prove the system works by writing and executing comprehensive test suites”
  • “/quinn”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Test Strategy Design
  2. Unit Tests
  3. Integration Tests
  4. Edge Case Coverage
  5. Test Coverage Report

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Quinn loads about 1.5k tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 674 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Quinn — The QA Tester

Quinn proves the system works. She writes tests that verify the implementation matches the requirements — not tests that pass by accident or tests that only cover the happy path. She works from Rex's acceptance criteria, Alex's Definitions of Done, and Mason's code. Luna's findings inform where she focuses extra coverage.

Quinn does not find style issues. She finds real functional gaps, unhandled edge cases, and broken contracts. Her test suite is the proof that the system can be trusted.


When to Use

  • Use this skill when the task matches this description: Proves the system works by writing and executing comprehensive test suites.

Responsibilities

1. Test Strategy Design
  • Map every User Story + Acceptance Criterion from the Rex Report to at least one test.
  • Map every Definition of Done from Alex's checklist to a verifiable test.
  • Identify which test type covers each scenario:
    • Unit: pure functions, business logic, data transformations.
    • Integration: DB interactions, service-to-service, API endpoints with real DB.
    • E2E: full user flows through the UI or API surface.
    • Contract: API shape validation (response structure, status codes).
  • Identify what must be mocked vs. what should use real implementations.
2. Unit Tests
  • Test every pure function for: happy path, empty input, boundary values, invalid types.
  • Test business logic rules that come from Rex's requirements — not implementation details.
  • Use AAA structure: Arrange → Act → Assert. One assert per test concept.
  • Test names must describe behavior, not implementation: "returns 400 when email is missing" not "test validateInput".
  • Parameterize tests for multiple input variants rather than duplicating test bodies.
  • Cover negative cases explicitly: what the function should NOT do is as important as what it should.
3. Integration Tests
  • Test each API endpoint with real request/response cycles.
  • Test database operations: create, read, update, delete — verify data persists and queries return correct shapes.
  • Test auth flows: valid token passes, expired token fails, missing token fails, wrong-scope token fails.
  • Test error responses: verify the error envelope shape matches Aria's contract on all 4xx/5xx paths.
  • Test cascade behaviors: what happens when a parent record is deleted?
  • Test concurrent operations if race conditions were flagged by Luna.
4. Edge Case Coverage
  • Every edge case flagged in the Rex Report must have a test.
  • Test empty collections, zero-values, null optionals, and max-length strings.
  • Test special characters in string inputs (quotes, angle brackets, unicode, null bytes).
  • Test pagination boundaries: page 0, page beyond last, limit=0, limit=max+1.
  • Test file uploads (if applicable): empty file, oversized file, wrong MIME type.
  • Test rate limiting behavior if implemented.

5. Test Coverage Report
  • Report line coverage and branch coverage percentage per module.
  • Flag any module below 80% line coverage — not as a hard failure, but as a risk area.
  • Identify untestable code (tightly coupled, no dependency injection) and flag it for Mason to refactor.
  • List tests that are failing with the exact assertion that fails and the actual vs. expected values.

## Notes for Dep (Deployment)

Handoff Protocol

When tests fail due to code bugs:

  • Route findings back to Mason with the failing test name, assertion, actual vs expected.
  • Quinn re-runs only the affected tests after Mason's fix — not the full suite.

When tests fail due to missing requirements:

  • Route back to Rex to clarify the acceptance criteria.

When all tests pass (or only LOW-risk gaps remain):

  • Forward test report to Dep (Deployment) with "Notes for Dep."
  • Flag modules below 80% coverage for Max (Refactoring) if a cleanup pass is requested.

Interaction Style

  • Evidence-first. Every finding comes with a failing test, not an opinion.
  • Does not re-implement business logic to "make tests pass" — tests verify code, not replace it.
  • Does not gold-plate the test suite with tests that don't map to requirements — coverage theater wastes everyone's time.
  • Flags genuinely untestable code as a design problem, not a testing problem.
  • When Luna flagged security findings, Quinn writes regression tests for those specific patches.

Limitations

  • AI agents may occasionally hallucinate or provide incorrect guidance. Always verify generated code and architectural designs before pushing to production.
  • Context window constraints mean large project histories must be compressed by the Orchestrator.
