Large changes are difficult to test, review, and recover when problems appear late. This skill breaks work into complete increments with explicit tests, verification, and rollback points.

Long sessions can turn assumptions into accepted facts and hide costly failure modes. This skill applies bounded, fresh-context adversarial review before non-trivial decisions stand.

Debugging failures by guesswork wastes time and can hide the real cause. This skill provides a repeatable process for reproducing, isolating, fixing, and verifying problems.

Teams often lack measurable quality standards, allowing checks and thresholds to drift during development. This skill defines a shared contract and connects each constraint to practical enforcement.

Coding agents lose accuracy when context is incomplete, stale, or excessive. This skill provides practical structures for focused sessions, durable rules, and reliable handoffs.

Complex code slows reviews, maintenance, and debugging. This skill guides focused refactoring that improves clarity while preserving behavior, errors, side effects, and tests.

Unclear contracts, inconsistent errors, and unsafe retries make APIs difficult to use and evolve. This skill provides practical patterns for typed interfaces, validation boundaries, compatibility, pagination, and idempotency.

Browser bugs can hide behind static code and incomplete unit tests. This skill uses Chrome DevTools MCP to inspect live behavior and verify fixes with runtime evidence.

Manual test design and fragmented tools slow reliable releases. This skill plans, writes, runs, and reports automated, API, performance, and CI tests.

Complex systems require explicit boundaries, trade-offs, and operational constraints. This skill structures architecture analysis, diagrams, decisions, and documentation for review.

Search teams need reliable guidance across indexing, ranking, semantic retrieval, and evaluation. This skill provides practical workflows and examples for building and improving search systems.

Full-stack teams often lack a repeatable way to measure performance and locate bottlenecks. This skill provides testing workflows, diagnostic commands, optimization guidance, and report structures.

Payment teams need consistent designs for transactions, channels, reconciliation, security, and failure handling. This skill provides structured guidance, examples, and review checklists.

Mobile teams must coordinate platform architecture, tooling, testing, performance, and release requirements. This skill provides practical guidance and examples for native and cross-platform workflows.

Backend projects require consistent choices across APIs, databases, security, performance, and deployment. This skill provides structured workflows, checklists, commands, and FastAPI examples.

Les demandes de codage complexes échouent souvent lorsque les prochaines étapes sont vagues. Cette skill transforme les exigences en plans clairs avec fichiers, tests, commandes et transmissions d'exécution.

Les échecs de l’audit de contraste Lighthouse peuvent masquer des résultats SEO et d’accessibilité exploitables. Cette compétence fournit des vérifications ciblées et des modèles de correction pour les problèmes de contraste CSS.

L’ajout de langues à un site Next.js peut casser le routage, le SEO et les fichiers de traduction. Cette skill fournit des scripts, des listes de contrôle et des références pour un déploiement i18n structuré.

Le code terminé a encore besoin d’un chemin propre vers le workflow principal. Cette compétence guide les vérifications de tests, les choix de merge ou de pull request, et le nettoyage de branche avec confirmation.

Les tâches vagues confiées aux agents de codage dérivent souvent, répètent le travail ou s’arrêtent sans preuve. Cette compétence transforme les demandes en spécifications de boucles délimitées avec vérificateurs, règles d’arrêt et dossiers de transmission.
