coral-skills gives Codex and other coding agents a single entrypoint for Coral work. It can now take an application requirement through agent-role design, graph topology, Koog or existing-agent integration, Puppet/API ingress, custom-tool callbacks, session lifecycle code, and runtime verification. It still routes operational questions to the smallest relevant reference and uses the target runtime's machine-readable schema as the source of truth.

Build An Agent System

Point Codex at an application repository and ask for the outcome directly:

$coral-skills Build a Coral agent system for this application. Users ask a
question, specialists collaborate in an open graph, and the app stores one
approved structured answer. Implement the first working slice and show me the
real session threads.

The skill guides Codex to:

• distinguish role prompts from genuinely separate agent implementations;
• compile user and product signals into a deterministic, testable graph specification;
• preserve application ownership of users, permissions, artifacts, and durable state;
• use Coral groups, threads, mentions, and Puppet/API ingress for real collaboration;
• wire least-privilege custom tools for application reads, writes, and result callbacks;
• build payloads from the live Coral schema instead of remembered request shapes;
• verify registry resolution, connected agents, real messages, results, failures, and session cleanup.

Skill

Invocation	Description
/coral-skills in Claude Code, $coral-skills in Codex	Build and operate Coral agent systems, or route a focused Coral task to the minimal runtime, integration, Cloud, custom-tool, or topology guidance.

Reference Routing

The public skill is a strict router. It loads one primary reference by default and adds a second only when the request crosses boundaries, such as Cloud plus custom tools or app integration plus session control.

Reference	Used for
build-application-agent-system.md	Turning an application requirement into agents, graph topology, conductor code, app callbacks, and runtime proof.
coral-setup.md	Installing, starting, stopping, inspecting, configuring, or troubleshooting Coral Server.
coral-runtime-reference.md	Finding the current machine-readable Coral API, OpenAPI schema, endpoint shapes, manifests, and source fallback.
coralize-your-agent.md	Connecting developer-owned agents through Coralizer, .coral, ~/.coral, coral-agent.toml, or config-file registry discovery.
coral-built-in-agent-setup.md	Installing and verifying the packaged example agent templates.
coral-session-control.md	Creating, polling, messaging, watching, inspecting, and closing concrete Coral sessions.
coral-app-integration.md	Wiring Coral into an application while keeping runtime/session coordination separate from durable app state.
cloud-runtime.md	Coral Cloud API keys, marketplace agents, Cloud Console payloads, LLM proxy, billing, and hosted-runtime boundaries.
custom-tools.md	App callbacks, customTools, customToolAccess, APP_BASE_URL, application IDs, secrets, and signature verification.
setup-patterns.md	Session ownership, conductor services, self-hosted deployments, and orchestration patterns.
coral-coordination-topologies.md	Choosing or reviewing multi-agent communication structures in Coral terms.
topologies.md	Supporting vocabulary for common and niche multi-agent coordination topologies.

Getting Started

1. Install the plugin for Claude Code or Codex.
2. Invoke /coral-skills in Claude Code or $coral-skills in Codex.
3. Ask for the product outcome directly: build an application agent system, start a server, inspect a schema, coralize an agent, wire a Cloud custom-tool callback, operate a session, or reason about a coordination topology.
4. When exact API calls matter, the skill should fetch the current BASE_URL/api_v1.json or use the most relevant source fallback.

For Cloud Console exports or marketplace agents, the skill routes agents to the Cloud runtime and custom-tool callback checklists without copying the full Cloud API schema into the skillset.

Prerequisites

• Claude Code or Codex.
• Node.js/npm for npx coralos-dev@latest and Coralizer workflows.
• Optional agent CLIs only when installing matching example templates.
• Coral Cloud credentials only when the user is working with Cloud-specific sessions, marketplace agents, billing, LLM proxy, or custom-tool callbacks.
