Claude Code Skills and Agents
Claude Code Skills & Agents
A Claude Code plugin bundling skills and sub-agents: deep research, image generation, GitHub work, code review and model switching
High risk
We rate an entry high when the tool writes to external systems, handles money, production databases or secrets, or runs arbitrary commands. The CLI installs it only with your consent.
Why this level
- Skills run shell commands and external CLIs, access the network and work with GitHub
- They need external API keys, and the manual install overwrites the ~/.claude directory
Install
In your terminal, with SkillFoxx CLI
npx skillfoxx add plugins/claude-code-skills-agentsDetects the agents on your machine, checks the risk and pins the version.
Other ways to install
Assembled automatically, review before installing.
Run one by one in the Claude Code chat
/plugin marketplace add feiskyer/claude-code-settings
/plugin install claude-code-settings@claude-code-settingsInstall the bundle: /plugin marketplace add feiskyer/claude-code-settings, then /plugin install claude-code-settings. A single skill can be added via npx skills add feiskyer/claude-code-settings.
Other ways from the author
/plugin marketplace add feiskyer/claude-code-settings
/plugin install claude-code-settingsThe main plugin includes all skills and sub-agents. Do not install it together with the standalone sub-plugins from the same marketplace.
This is third-party code. Review the repository files before installing.
What it does
The plugin installs twelve skills and several sub-agents into Claude Code with one command through the official marketplace. The skills include brainstorming to work an idea into a spec, deep-research with multi-agent orchestration, github-fix-issue and github-review-pr for issue work and pull request review, skill-creator to build and score your own skills, handoff to pass context between sessions, grill-me for a rigorous decision interview, translate for technical articles, codex-skill to delegate tasks to the Codex CLI, and nanobanana-skill and gpt-image-skill for image generation via Gemini and OpenAI. The sub-agents cover PR review, issue fixing, analyzing and improving instructions, documenting findings and UI work. Separately there are settings.json templates for various model providers, including a GitHub Copilot gateway and LiteLLM. Individual skills can also be installed one at a time as standalone plugins.
Who it is for. For Claude Code developers who want a ready set of working skills and sub-agents instead of assembling a config from scratch.
Good fit when
- You want a ready set of skills for research, GitHub work and code review
- You want to delegate tasks to the Codex CLI or run multi-agent deep research
- You want settings.json templates for different model providers and switching between them
Not a fit when
- You need a single narrow skill rather than the whole bundle
- The image skills need Gemini or OpenAI keys that you do not have
Example request
Run a deep research pass on this topic and produce a report with conclusions and sourcesLimitations
Some skills need external keys and tools: nanobanana-skill uses GEMINI_API_KEY, gpt-image-skill uses OPENAI_API_KEY, youtube-transcribe-skill uses yt-dlp or a browser MCP, and codex-skill needs the Codex CLI installed. The Gemini and OpenAI APIs are unreachable from Russia without a VPN, so the image skills and some gateways will not work there, while brainstorming, deep-research, translate, handoff and grill-me do not depend on external services. The settings.json file is the author's personal template, is not installed by the plugin and is edited by hand. MIT licensed.
How to disable. Remove the plugin via /plugin, then optionally remove the marketplace with /plugin marketplace remove claude-code-settings.
Security check
- Skills run shell commands and external CLIs, access the network and work with GitHub
- They need external API keys, and the manual install overwrites the ~/.claude directory
README in short
The README describes a set of skills and sub-agents for Claude Code that adds deep research, image generation, GitHub automation and model switching. The recommended install is via the official marketplace: /plugin marketplace add feiskyer/claude-code-settings and /plugin install claude-code-settings. Individual skills install via npx skills, and a manual path copies into ~/.claude, which overwrites the directory. The README lists twelve skills with triggers and dependencies, six sub-agents and settings.json templates for providers such as Copilot, LiteLLM, DeepSeek, Qwen and others. The settings.json file is configured by hand and points at the copilot-gateway. MIT licensed.
FAQ
Do I install the whole bundle?
No. The main plugin includes all skills and sub-agents, but individual skills can be added one at a time via npx skills or as standalone plugins from the same marketplace.
Does the plugin install settings.json?
No. That is the author's personal template for model provider setup, edited by hand; the plugin does not touch it.
