Claude CodeCodexCursorGitHub Copilot

The agents AI sub-agent is a production-ready plugin marketplace containing 91 plugins, 202 domain-expert agents, 180 modular skills, and 105 slash commands that work natively across six major AI coding environments. Built from a single Markdown source, it delivers harness-specific artifacts for Claude Code, Codex CLI, Cursor, OpenCode, GitHub Copilot, and Gemini CLI without lowest-common-denominator compromises. Each plugin is isolated and composable, loading only its components into context to provide developers with specialized capabilities ranging from Python development and security scanning to infrastructure setup and SEO optimization.

Key Features

91 granular, single-purpose plugins covering development, security, infrastructure, ML, documentation, and business domains
202 domain-expert agents organized by specialty (architecture, languages, security, data, docs, SEO)
180 modular skills with progressive disclosure that load only when activated
Multi-harness support generating native artifacts for Claude Code, Codex CLI, Cursor, OpenCode, Gemini CLI, and GitHub Copilot from one source
16 orchestrator workflows for multi-agent coordination (full-stack, security, ML, incident response)
Tiered model strategy mapping agents to appropriate LLMs from Haiku (fast tasks) to Opus (production-critical work)
Three-layer plugin evaluation framework (static analysis, LLM judge, Monte Carlo simulation) for quality certification
External memory integration via Pensyve with direct upstream support for all six harnesses

agents — FAQ

What is the agents AI sub-agent?+

The agents AI sub-agent is a multi-harness plugin marketplace delivering 91 production-ready plugins, 202 domain-expert agents, and 180 skills to six major AI coding environments (Claude Code, Codex CLI, Cursor, OpenCode, Gemini CLI, GitHub Copilot) from a single Markdown source.

How do I install the agents marketplace in Claude Code?+

Run /plugin marketplace add wshobson/agents to add the marketplace, then /plugin install <plugin-name> to install individual plugins like python-development. Each plugin loads only its own agents, skills, and commands into context.

Which AI clients support the agents marketplace?+

The agents marketplace works natively with Claude Code, Codex CLI, Cursor, OpenCode, Gemini CLI, and GitHub Copilot. Codex and Cursor install from committed registries, while Gemini and OpenCode require clone plus make generate.

Does the agents marketplace require API keys?+

The marketplace itself requires no additional API keys beyond those already configured for your chosen AI coding client (Claude Code, Codex, Cursor, etc.). The tiered model strategy maps agents to Haiku, Sonnet, or Opus based on task complexity.

Is the agents marketplace free to use?+

Yes, the agents marketplace is MIT-licensed and free to use. LLM costs apply based on your client's existing pricing (e.g., Claude API usage) and the tiered model strategy employed by agents.

How does multi-harness support work?+

The marketplace generates harness-native artifacts for each of six platforms from one Markdown source. Each adapter produces idiomatic formats (not lowest-common-denominator translations), respecting platform-specific constraints like Codex CLI's 8 KB skill cap and OpenCode's permission blocks.

How do I install agents?+

Open the source repository on GitHub and follow its README. agents is a agent — MCP Agents Market links you directly to the official repo.
