Automated summary
A specialized skill for applying React 19's useTransition and useOptimistic hooks within the arbitragex-v2 monorepo, following a strict 'Zero-Mocks / Fail-Closed' doctrine with validation through CI and E2E tests.
Strengths
- Enforces a rigorous validation pipeline (lint, typecheck, build, tests, audit, E2E).
- Provides explicit activation triggers for server actions form state.
- Requires research-backed benchmarks and statistical evidence.
- Aligns with repo-specific architecture and schema contracts.
Limitations
- Tightly coupled to the arbitragex-v2 monorepo and its doctrine, so it is not a generic React tutorial.
- May abort tasks on CI failures or schema drift, requiring fix-forward actions.
- Focuses on process and doctrine; actual hook implementation details are not covered.
When implementing or improving React 19 useTransition/useOptimistic patterns in a server actions form state context within the arbitragex-v2 frontend.
When working outside the arbitragex-v2 repo or when you need a general introduction to React 19 hooks without the Post-Doc rigor.
Security analysis
SafeSkill is a static guide with no executable payloads. The Quick Start command runs a test suite with safe environment variables, and all instructions focus on development validation and reporting within a known repository.

Core Workflow
- Cargar contexto del repo
hefarica/arbitragex-v2(rama actual, último PR, estado de CI). - Identificar el subsistema impactado dentro de los archivos del repo listados arriba.
- Aplicar la doctrina del nivel Post-Doc sin desviaciones.
- Validar contra:
lint → typecheck → build → tests → audit → E2E → deploy. - Reportar evidencia en formato Markdown forense (logs, traces, métricas, hash de commit).
Doctrina del Nivel
- Aporte de investigación: paper o RFC referenciado.
- Benchmarks reproducibles con criterio estadístico (95% CI).
- Comparativa contra estado del arte público.

From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/advanced-react-19-usetransition-useoptimistic-msh3uudi/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/advanced-react-19-usetransition-useoptimistic-msh3uudi' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/advanced-react-19-usetransition-useoptimistic-msh3uudi/download' --output '.skill-downloads/advanced-react-19-usetransition-useoptimistic-msh3uudi/SKILL.md.part' && mv '.skill-downloads/advanced-react-19-usetransition-useoptimistic-msh3uudi/SKILL.md.part' '.skill-downloads/advanced-react-19-usetransition-useoptimistic-msh3uudi/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
This file does not provide a usable name/description header for this native procedure. It remains available to download and inspect; use the manual method below.
Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/advanced-react-19-usetransition-useoptimistic-msh3uudi/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
