Resumen

Resumen Principal

La interfaz de línea de comandos (CLI) skills se erige como una herramienta central para el ecosistema abierto de habilidades de agentes, diseñada para potenciar las capacidades de los agentes de codificación. Permite a los desarrolladores integrar conjuntos de instrucciones reutilizables que extienden las funcionalidades de sus agentes, soportando una impresionante lista de más de 35 plataformas, incluyendo referentes como OpenCode, Claude Code y Cursor. Su flexibilidad se manifiesta en la diversidad de formatos de origen para la instalación de habilidades, desde repositorios de GitHub y GitLab hasta rutas locales. La arquitectura de skills facilita la creación de tareas especializadas, como la generación de notas de lanzamiento o la integración con herramientas externas. Esto subraya el compromiso con la automatización avanzada y la personalización profunda, permitiendo que los agentes de IA se adapten a flujos de trabajo específicos y se conviertan en asistentes de desarrollo altamente eficientes y modulares.

Elementos Clave

Instalación y Formatos de Origen Diversos: La CLI skills permite una instalación extremadamente flexible a través del comando npx skills add. Soporta una amplia gama de fuentes, incluyendo shorthand de GitHub (owner/repo), URL completas de GitHub y GitLab, rutas directas a habilidades dentro de repositorios específicos, URLs de cualquier tipo de git, y rutas locales (./my-local-skills). Esta versatilidad asegura que los usuarios puedan obtener habilidades de diversas fuentes con gran facilidad y adaptabilidad.
Gestión Integral del Ciclo de Vida de las Habilidades: La herramienta proporciona comandos robustos para la administración completa de las habilidades. Los usuarios pueden listar las habilidades instaladas (npx skills list), buscar nuevas habilidades (npx skills find), removerlas (npx skills remove), verificar si hay actualizaciones (npx skills check), y actualizar todas las habilidades a sus últimas versiones (npx skills update). Esto garantiza un control eficiente sobre el inventario de habilidades de cada agente.
Definición Estructurada de Habilidades: Una habilidad se define como un directorio que contiene un archivo SKILL.md. Este archivo emplea un frontmatter YAML con campos obligatorios como name (identificador único) y description (explicación breve de su función). Opcionalmente, se puede incluir metadata.internal: true para habilidades privadas. El cuerpo del archivo SKILL.md contiene las instrucciones detalladas para el agente, organizadas con secciones como "When to Use" y "Steps", lo que promueve una documentación clara y ejecutable.
Alcance de Instalación y Compatibilidad con Agentes: Las habilidades pueden instalarse en dos ámbitos principales: Proyecto (predeterminado, ubicadas en ./<agent>/skills/ y compartidas con el equipo) o Global (usando la bandera -g, ubicadas en ~/ <agent>/skills/ y disponibles en todos los proyectos del usuario). La CLI detecta automáticamente los agentes instalados y es compatible con una extensa lista de ellos, desde Amp y Claude Code hasta Cursor y GitHub Copilot. Aunque las habilidades son generalmente compatibles gracias a una especificación compartida, algunas características avanzadas pueden ser específicas de cada agente.

Análisis e Implicaciones

El ecosistema skills implica una estandarización crucial para la interacción entre IA y flujos de trabajo de desarrollo, permitiendo una mayor eficiencia y personalización. Su diseño promueve la creación y reutilización de inteligencia operativa, transformando los agentes de codificación en herramientas altamente especial

What are Agent Skills?

Agent skills are reusable instruction sets that extend your coding agent's capabilities. They're defined in SKILL.md files with YAML frontmatter containing a name and description.

Skills let agents perform specialized tasks like:

Generating release notes from git history
Creating PRs following your team's conventions
Integrating with external tools (Linear, Notion, etc.)

Discover skills at skills.sh

Note

Kiro CLI users: After installing skills, manually add them to your custom agent's resources in .kiro/agents/<agent>.json:

{
  "resources": ["skill://.kiro/skills/**/SKILL.md"]
}

The CLI automatically detects which coding agents you have installed. If none are detected, you'll be prompted to select which agents to install to.

Creating Skills

Skills are directories containing a SKILL.md file with YAML frontmatter:

---
name: my-skill
description: What this skill does and when to use it
---

# My Skill

Instructions for the agent to follow when this skill is activated.

## When to Use

Describe the scenarios where this skill should be used.

## Steps

1. First, do this
2. Then, do that

Required Fields

name: Unique identifier (lowercase, hyphens allowed)
description: Brief explanation of what the skill does

Optional Fields

metadata.internal: Set to true to hide the skill from normal discovery. Internal skills are only visible and installable when INSTALL_INTERNAL_SKILLS=1 is set. Useful for work-in-progress skills or skills meant only for internal tooling.

---
name: my-internal-skill
description: An internal skill not shown by default
metadata:
  internal: true
---

Skill Discovery

The CLI searches for skills in these locations within a repository:

Root directory (if it contains SKILL.md)
skills/
skills/.curated/
skills/.experimental/
skills/.system/
.agents/skills/
.agent/skills/
.augment/skills/
.claude/skills/
./skills/
.cline/skills/
.codebuddy/skills/
.commandcode/skills/
.continue/skills/
.crush/skills/
.cursor/skills/
.factory/skills/
.goose/skills/
.junie/skills/
.iflow/skills/
.kilocode/skills/
.kiro/skills/
.kode/skills/
.mcpjam/skills/
.vibe/skills/
.mux/skills/
.openhands/skills/
.pi/skills/
.qoder/skills/
.qwen/skills/
.roo/skills/
.trae/skills/
.windsurf/skills/
.zencoder/skills/
.neovate/skills/
.pochi/skills/
.adal/skills/

Plugin Manifest Discovery

If .claude-plugin/marketplace.json or .claude-plugin/plugin.json exists, skills declared in those files are also discovered:

// .claude-plugin/marketplace.json
{
  "metadata": { "pluginRoot": "./plugins" },
  "plugins": [{
    "name": "my-plugin",
    "source": "my-plugin",
    "skills": ["./skills/review", "./skills/test"]
  }]
}

This enables compatibility with the Claude Code plugin marketplace ecosystem.

If no skills are found in standard locations, a recursive search is performed.

Compatibility

Skills are generally compatible across agents since they follow a shared Agent Skills specification. However, some features may be agent-specific:

Feature	OpenCode	OpenHands	Claude Code	Cline	CodeBuddy	Codex	Command Code	Kiro CLI	Cursor	Antigravity	Roo Code	Github Copilot	Amp	Clawdbot	Neovate	Pi	Qoder	Zencoder
Basic skills	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes
`allowed-tools`	Yes	Yes	Yes	Yes	Yes	Yes	Yes	No	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	No
`context: fork`	No	No	Yes	No	No	No	No	No	No	No	No	No	No	No	No	No	No	No
Hooks	No	No	Yes	Yes	No	No	No	No	No	No	No	No	No	No	No	No	No	No

Troubleshooting

"No skills found"

Ensure the repository contains valid SKILL.md files with both name and description in the frontmatter.

Skill not loading in agent

Verify the skill was installed to the correct path
Check the agent's documentation for skill loading requirements
Ensure the SKILL.md frontmatter is valid YAML

Permission errors

Ensure you have write access to the target directory.

Environment Variables

Variable	Description
`INSTALL_INTERNAL_SKILLS`	Set to `1` or `true` to show and install skills marked as `internal: true`
`DISABLE_TELEMETRY`	Set to disable anonymous usage telemetry
`DO_NOT_TRACK`	Alternative way to disable telemetry

# Install internal skills
INSTALL_INTERNAL_SKILLS=1 npx skills add vercel-labs/agent-skills --list

Telemetry

This CLI collects anonymous usage data to help improve the tool. No personal information is collected.

Telemetry is automatically disabled in CI environments.
