Publish the CloudBurn skill through agent marketplaces

[axonstone]

What

Package and publish the CloudBurn skill from #129 through the agent distribution channels that exist today. Keep the workflow in one Agent Skill and add thin marketplace wrappers where a client needs its own manifest.

Why

A skill hidden in the repository won't reach many users. People should be able to install it with the package flow their agent already uses, while CloudBurn keeps one copy of the instructions, tests, and safety rules.

Publishing options

Channel	Current publishing path	Proposed CloudBurn support
skills.sh	Host an Agent Skill in a public GitHub repository. skills.sh lists it automatically after users install it with the skills CLI.	Make the skill installable with npx skills add towardsthecloud/cloudburn --skill cloudburn, then verify its listing and security audit.
Agent Skills	Open SKILL.md format used across compatible agents. This is a format, not a store.	Treat this as the canonical source format and validate it with skills-ref.
Claude Code	A plugin can bundle skills and ship through a Git-hosted .claude-plugin/marketplace.json. Authors can also submit a plugin to Anthropic's official marketplace.	Add a cloudburn Claude Code plugin and a marketplace entry, test local and GitHub installation, then submit it to the official marketplace if it meets their review requirements.
Codex and ChatGPT desktop	A plugin uses .codex-plugin/plugin.json, can bundle skills, and can ship through a Git marketplace added with codex plugin marketplace add.	Add a Codex plugin manifest and marketplace entry around the same skill. Don't fork the workflow text.

Scope

• Decide whether distribution files live in this repository or a small towardsthecloud/agent-skills repository. Record the choice in durable docs.
• Keep one canonical cloudburn skill. Vendor plugin folders should reference or package that source without hand-maintained copies.
• Add install metadata, versioning, license, repository, homepage, and CloudBurn branding required by each marketplace.
• Add CI checks for the Agent Skills validator plus Claude Code and Codex plugin and marketplace validation.
• Test clean installs for:
  • npx skills add towardsthecloud/cloudburn --skill cloudburn
  • a GitHub-hosted Claude Code marketplace and plugin
  • a GitHub-hosted Codex marketplace and plugin
• Add installation, update, uninstall, permissions, AWS credential, and trust guidance to the user docs.
• Publish the skills.sh listing and security audit after the first tracked install.
• Submit the Claude plugin to Anthropic's official marketplace only after the independent marketplace package works.
• Research whether OpenAI accepts external submissions to its curated Plugins Directory. Until there's a documented submission route, publish the Git marketplace without promising a curated listing.
• Track install commands and marketplace links from the CloudBurn README and website.

Acceptance criteria

• A user can install the same CloudBurn workflow through skills.sh, Claude Code, or Codex using documented commands.
• Each package passes its native validator and loads the canonical skill.
• Updating the core skill doesn't require editing duplicate workflow instructions.
• Marketplace pages state that the agent runs the local CloudBurn CLI and may call AWS APIs during live discovery.
