using-agent-skills

using-agent-skills is a skill for Claude Code, Codex from jcarlosrodicio/opencode-agent-orchestration-kit. It costs 48 tokens per session (1,816 once invoked), scanned A, original, Apache-2.0.

A guide for applying Clean Architecture, a way of organizing software so core business rules stay separate from frameworks, databases, and user interfaces.

In plain words
What is it for?
Use it to review architecture, check dependency direction, separate layers, or plan software around SOLID design principles.
Why use it?
It reveals misplaced dependencies and tangled layers that make code harder to change, test, and understand.

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

using-agent-skills 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 6d 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.

Using Agent Skills

Overview

Agent Skills is a collection of engineering workflow skills organized by development phase. Each skill encodes a specific process that senior engineers follow. This meta-skill helps you discover and apply the right skill for your current task.

Skill Discovery

When a task arrives, identify the development phase and apply the corresponding skill:

Core Operating Behaviors

These behaviors apply at all times, across all skills. They are non-negotiable.

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.

using-agent-skills is a skill published in the GitHub repository jcarlosrodicio/opencode-agent-orchestration-kit (108 stars, last pushed 2d ago), licensed Apache-2.0. It adds 48 tokens to every session and 1,816 once invoked, about $0.0002 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.
