20 Test-Driven Development alternatives
Test-Driven Development: Enforce a real red-green-refactor loop when implementing features or fixes, so behaviour is specified before it is written. 20 agent skills do similar work, most sharing Testing, Quality and TDD, ranked by how much they have in common with Test-Driven Development.

by Jesse Vincent
Never claim work is complete, fixed, or passing without running the check and reading the output first.
-
by Jesse Vincent
An agentic software-development methodology: composable skills that push a coding agent through spec, plan, TDD and review instead of straight into code.
Also: TDD
-
by Sentry
Review pull requests against a real engineering practice — security, performance, testing, and design, in that order.
Also: Quality
-
by Jesse Vincent
Respond to code review feedback with technical rigour — verify each point instead of agreeing with everything.
Also: Quality
-
by Jesse Vincent
Prepare and request a code review that checks the work against its original requirements, not just its syntax.
Also: Quality
-
by Microsoft
Microsoft's official Playwright skill — drives a real browser from the command line using accessibility snapshots and element refs, and plans, generates and heals Playwright tests.
Also: Testing
-
by Jesse Vincent
A disciplined debugging process — reproduce, isolate, hypothesise, and verify — used before proposing any fix.
Also: Testing
-
by SerpApi
A protocol for measuring whether agents can discover and use your tool without being told about it — WITH/WITHOUT trials, binary scoring, and lift as the only metric. The subject under test is your docs, not the model.
Also: Testing
-
by Datadog
Official Datadog skill for investigating one flaky test — pulls its history and failure pattern, categorises the root cause and recommends fixing, quarantining or escalating.
Also: Testing
-
by Datadog
Official Datadog skill that triages a failing PR pipeline, attributing every CI failure as flaky, infra or genuine regression and proposing a targeted fix.
Also: Testing
-
by Grafana Labs
Grafana's official k6 skill: generate a load, stress, spike or soak test from a plain-language brief, then actually run the script before handing it over.
Also: Testing
-
by arpitg1304
Ten SKILL.md modules that give coding agents real ROS engineering judgement — ROS 1 and ROS 2, design patterns, perception, testing, Docker, bringup and robot security.
Also: Testing
-
by TestMu AI
TestMu AI's official skill for generating production-grade Playwright suites in TypeScript, JavaScript, Python, Java or C#, locally or on a 3,000-combination browser cloud.
Also: Testing
-
by Cypress.io
Cypress' official skill for writing, updating and repairing E2E and component tests — and it triggers on "write tests" even when nobody says Cypress.
Also: Testing
-
by Anthropic
Interact with and test local web applications using Playwright — verify frontend behavior, debug UI, capture screenshots, and read browser logs.
Also: Testing
-
by Trail of Bits
Trail of Bits' skill for writing production-quality Semgrep rules — pattern design, taint mode for data-flow bugs, and mandatory test-driven validation.
Also: Testing
-
by Oldcircle
Find where a photo was taken: EXIF, OCR, OpenStreetMap, skyline and satellite matching, with coordinates, error radius and evidence images.

-
by AMD
AMD's official meta-skill: permanently reroutes an agent's image generation, text-to-speech and speech-to-text to a local Lemonade Server instead of a paid cloud API.
Also in Development
-
by Trail of Bits
CodeQL, Semgrep and SARIF static-analysis toolkit from Trail of Bits: taint tracking, fast pattern scans and merged, deduplicated security findings for coding agents.
Also in Testing & QA

by Google Maps Platform
Google's official agent skill for writing production Maps Platform code — grounded in freshly fetched docs, with a demo key path that needs no billing account.
Also in Development
