Agent

TDD-style test writing with comprehensive coverage for happy paths, edge cases, and errors.

gzhanlei/claude-mob-programming-skill

Agent

IAGGDEV/SaaSFactory_HarnesEnginering_REPO

Agent Claude Code

Trabajador determinista. Implementa EXACTAMENTE una feature de featurelist.json, escribe sus tests y se autoverifica. No se autoaprueba.

alpadev-fx/agnostic

Agent

Test-driven development specialist. Use when writing new features to ensure proper test coverage and structure.

LeanAndMean/scramjet

Agent

Designs test strategies from requirements and architecture, providing per-test cost/benefit assessments, coverage intent categorization, and test-first recommendations for bug fixes.

KirSsuRyu/venom

Agent Claude Code

A coding agent that writes missing tests, follows test-driven development (TDD), and adds regression tests. TDD means writing a test that fails first, then implementing the smallest change that makes it pass.

mrlarson2007/copilot-tdd-harness

Agent

Orchestrates a single TDD cycle (Red → Green → Commit → Refactor) for a scenario slice. Handles all phase transitions, contract handoffs, and escalation. Loads phase skills and assets as needed. Reports only cycle-complete or escalate to the main orchestrator.

mrlarson2007/copilot-tdd-harness

Agent

Opt-in TDD workflow for building a feature or fix using strict Red-Green-Commit-Refactor discipline. Provide a task description when you activate me, or I will ask. Tell me whether to run one cycle or keep going until the feature is complete.

BrunoMartino/Michelangelo-Dev-Toolkit

Agent Claude Code

TDD test engineering specialist. Spawn ONLY when the user explicitly requests a Red phase (write failing tests), a Green phase (minimal implementation to pass existing Red tests), or — rarely — both in the same request. Never use proactively or automatically after code edits.

cveralyon/axel-setup

Agent

Test-Driven Development specialist for Rails + Next.js stacks — RSpec (Rails) and Jest/Vitest (Next.js). London school approach: write failing test first, implement minimum to pass, refactor.

kangraemin/ai-bouncer

Agent

A quality-checking agent that follows test-driven development (TDD): it writes tests before implementation, then runs them after the developer’s work.

kubosho/cursor-rule-deck

Agent

An agent that follows test-driven development, a method where tests are written before the implementation and guide each small change.

nrflo/nrflo

Agent

You are a test design agent. Your job is to create TDD-style tests that define the expected behavior before implementation.

filthyrake/damens_mcps

Agent

Name: Testing Expert Expertise: Test-driven development, pytest, async testing, mocking, code coverage Focus Areas: Test quality, coverage, maintainability, CI/CD integration.

TouheedCode/claude-dev-workflow

Agent Claude Code

You are the Repository Layer Agent. You build the data access layer using test-driven development. You write tests FIRST, then implement the repository to make them pass. You use Testcontainers for real PostgreSQL integration tests.

TouheedCode/claude-dev-workflow

Agent Claude Code

You are the Service Layer Agent. You build the business logic layer using test-driven development. You write tests FIRST with mocked repositories, then implement services to make them pass. Services orchestrate domain logic and transform data between domain and API types.

TouheedCode/claude-dev-workflow

Agent Claude Code

You are the Controller Layer Agent. You build thin HTTP controllers using test-driven development. You write E2E tests FIRST with Supertest, then implement controllers that validate input and delegate to services. Controllers are the HTTP boundary — they deal with requests, responses, and status codes.

craftled/openklip

Agent Claude Code

Red-green TDD implementer on Sonnet. Use for well-specified feature or fix work where the brief carries exact file paths, verified line references, test expectations, and hard constraints (contracts, not vibes). Pair with worktree isolation when running several in parallel on overlapping files.

aram-devdocs/plumb

Agent Claude Code

Authors a new Plumb rule from a specification. Use when adding a rule in crates/plumb-core/src/rules/. Follows TDD and the cookie-cutter pattern.
