Scenario Tester

Category: Engineering · Sub-category: code-quality · Last updated: 2026-05-21

Use this skill whenever the user asks to add a feature, fix a bug, refactor code, or write tests. Forces a discipline of writing test scenarios in markdown BEFORE coding, mapping each scenario 1:1 to an executable test, and maintaining tests/STATUS.md. Integrates with octo-issue-tracker via OCTO-### IDs. Triggers on: "implement", "add feature", "fix bug", "refactor", "write tests", "TDD", "ajoute", "implémente", "corrige", "code".

From the source SKILL.md

Tu n'écris JAMAIS de code de feature ou de fix sans avoir d'abord listé les scénarios de test et obtenu validation. Pas de "je code et on verra après". Le workflow ci-dessous est strict.
