Andreas Agent Skills

andreasasprou/agent-skills·3 plugins

Extend Claude Code with a second-opinion oracle, destructive-command guardrails, and open-source tooling without wiring each piece yourself.

Overview

andreas-agent-skills is a plugin marketplace for the Build phase that adds Claude Code skills and safety hooks including Oracle, Safety-net, and Opensrc.

What is this marketplace?

Three plugins: Oracle (strategic advisor), Safety-net (destructive-command hooks), and Opensrc
Oracle Repo mode uses Codex SDK on your codebase; Web mode uses GPT-5.2 Thinking or GPT-5.2-pro for external truth
Safety-net intercepts and blocks high-blast-radius shell and file operations before they run
One-time marketplace add plus per-plugin /plugin install from andreas-agent-skills
Mix of skills (new capabilities) and hooks (action validation) in one curated repo
3 plugins listed: Oracle, Safety-net, Opensrc
Oracle exposes Repo and Web modes with model escalation on Web
Marketplace documents two extension types: skills and hooks

Compatible agents: Claude Code

Community signal: 7 GitHub stars.

What problem does it solve?

Claude Code agents can act on your repo and shell without a built-in second opinion or guardrails against destructive commands.

Who is it for?

Solo builders on Claude Code who want curated plugins for code review, pre-refactor blast-radius checks, and command interception without maintaining custom hook code.

Skip if: Teams on Cursor-only or non-Claude agents that cannot use /plugin marketplace install, or builders who need a full sales or domain-specific platform integration instead of agent extensions.

What do I get? / Deliverables

After adding the marketplace and installing plugins, you get /oracle for repo- or web-grounded advice and hook-level protection before risky operations execute.

BuildAgent skills & templates

The marketplace is primarily about installing Claude Code plugins—skills and hooks—that change how the agent works during implementation and day-to-day coding. Agent-tooling is the canonical shelf because every bundle item registers commands (e.g. /oracle) or lifecycle hooks rather than shipping a standalone app feature.

How it compares

Curated Claude Code plugin marketplace with skills and hooks, not a single SKILL.md task or an MCP server catalog.

Common Questions / FAQ

Who is Andreas Agent Skills for?

It is for Claude Code users who want a small, maintained set of agent skills and safety hooks rather than assembling extensions from scratch.

When should I use Andreas Agent Skills?

Use it when you need /oracle for codebase or web-backed technical decisions, or Safety-net before letting the agent run destructive shell or file operations.

How do I add Andreas Agent Skills to my agent?

Run /plugin marketplace add https://github.com/andreasasprou/agent-skills once, then /plugin install oracle@Andreas Agent Skills, safety-net@Andreas Agent Skills, or opensrc@Andreas Agent Skills as needed.
