deepseek-skills: Skill for Claude Code

.agents/.skills/skills/deepseek-code-quality/SKILL.md

deepseek-code-quality is a skill for Claude Code, Codex from gonzi-stack/deepseek-skills. It costs 83 tokens per session (3,216 once invoked), scanned A, original, MIT.

A set of code-writing standards for typed software, with examples mainly in TypeScript, a programming language with built-in type checking. It covers types, function design, safe database queries, security, error handling, and React components.

In plain words
What is it for?
Use it while designing functions, writing TypeScript or React code, handling database input, and checking application security and errors.
Why use it?
It helps prevent unclear types, unsafe data handling, weak error recovery, and common security or component-quality problems.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is gonzi-stack/deepseek-skills's own configuration. It tells Claude Code and Codex how to work on deepseek-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything deepseek-skills configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deepseek-code-quality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DeepSeek Code Quality Skill — Universal

Si deepseek-reasoning te enseña cómo pensar, esta skill te enseña cómo escribir. Los principios son universales. Los ejemplos usan TypeScript pero aplican a cualquier lenguaje tipado.


1. Tipos — Escribir código que se defiende solo

1.1 Nunca evadir el sistema de tipos

any, casts forzados, y type assertions son una rendición. Siempre existe un tipo correcto.

// ❌ WRONG — evadiendo el sistema de tipos
const result = (api.user as any).listItems?.();

// ✅ CORRECT — usando el tipo real
const result = api.user.listItems();

Si el compilador se queja, el problema es el tipo — no el cast. Leé el error, encontrá el tipo correcto.

Alternativas a any:

  • unknown — cuando el tipo es genuinamente desconocido; manejalo con type guards
  • Generics — cuando el tipo varía pero es predecible
  • Tipos de unión explícitos — cuando puede ser una de varias cosas conocidas

1.2 Tipos de retorno explícitos en funciones públicas

Las funciones que forman parte de la API de un módulo deben declarar su tipo de retorno:

// ❌ WRONG — el lector no sabe qué esperar
async function getUserById(id: string) {
  // ...
}

// ✅ CORRECT — contrato claro
async function getUserById(id: string): Promise<User | null> {
  // ...
}

1.3 Guards para valores potencialmente nulos

Antes de acceder a una propiedad, verificar que el objeto existe:

// ❌ WRONG — crash si rows[0] no existe
const user = rows[0];
return user.name;

// ✅ CORRECT
const user = rows[0];
if (!user) return null;
return user.name;

// ✅ CORRECT — alternativa concisa
return rows[0]?.name ?? null;

1.4 Estados explícitos en lugar de booleans ambiguos

// ❌ WRONG — ¿isActive: false significa suspendido? ¿eliminado? ¿bloqueado?
interface Resource {
  isActive: boolean;
}

// ✅ CORRECT — el estado es inequívoco
interface Resource {
  status: "active" | "suspended" | "deleted" | "pending";
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

deepseek-code-quality is a skill published in the GitHub repository gonzi-stack/deepseek-skills (2 stars, last pushed 6mo ago), licensed MIT. It adds 83 tokens to every session and 3,216 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
