deepseek

deepseek is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 15 tokens per session (301 once invoked), scanned A, original, MIT.

A family of AI models from DeepSeek, including models designed for coding and for solving problems through extended reasoning. Some of its models are available as open weights for local use.

In plain words
What is it for?
Use it to generate or understand code, work through mathematical and logical problems, call an AI model through an API, or run a supported distilled model locally.
Why use it?
It provides options for coding and reasoning, including lower-cost API use and running certain models privately on your own machines.

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 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 8d 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.

What it actually says

DeepSeek

DeepSeek (from China) disrupted the market in late 2024/2025 by releasing DeepSeek-V3 and R1 (Reasoning) with performance matching Claude/GPT-4 at 1/10th the cost.

When to Use

  • Cost Efficiency: The API is incredibly cheap.
  • Reasoning: DeepSeek-R1 uses Chain-of-Thought reinforcement learning (like OpenAI o1) but is open weights.
  • Coding: DeepSeek-Coder-V2 is a top-tier coding model.

Core Concepts

MLA (Multi-Head Latent Attention)

Architectural innovation that drastically reduces KV cache memory usage (allowing huge context).

DeepSeek-R1

A reasoning model that outputs its "thought process" before the final answer.

Best Practices (2025)

Do:

  • Use R1 for Math/Logic: It rivals o1-preview in math benchmarks.
  • Local Distillations: Run DeepSeek-R1-Distill-Llama-70B locally for private reasoning.

Don't:

  • Don't suppress thoughts: When using R1, the "thought" trace is valuable for debugging the model's logic.

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 is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 6mo ago), licensed MIT. It adds 15 tokens to every session and 301 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
