Description

This adds the aeon plugin, which ships the Aeon operator console skill.

Aeon is an open-source (MIT) autonomous agent framework that runs your own skills on a schedule in GitHub Actions. A skill is a Markdown file with a prompt; aeon.yml decides which skills run and when. The operator console is the single skill you drive an instance from:

• start from scratch (fork or mirror the repo, authenticate a model, wire one channel, get a first run to your phone)
• turn skills on or off and schedule or reschedule what runs, in your own timezone
• edit what an existing skill does, or retarget it through its var
• debug why a skill did not fire (disabled, unquoted schedule, disabled Actions, wrong repo)
• set the STRATEGY.md north star and the soul/ voice that ride in every run
• turn a coding-agent chat into a scheduled skill, and mine past coding-agent chats for repeated work worth automating

Install once merged:

copilot plugin install aeon@awesome-copilot

Disclosure: I work on Aeon (Aeon Inc, github.com/aeonfun), so I am affiliated with the project. The skill source is vendored into this repo under skills/aeon/ following the local-plugin format; it is the same operator skill that ships in the upstream repo. Framework and full skill catalog: https://github.com/aeonfun/aeon. Homepage: https://aeon.fun.

Additional Notes

• Files: plugins/aeon/ (plugin.json + README.md), skills/aeon/ (SKILL.md, six references/ files, and the mine-history.mjs script). The generated .github/plugin/marketplace.json and the docs/ plugin/skill tables were regenerated with npm start.
• Verified locally: npm run plugin:validate and npm run skill:validate pass, npm start leaves the tree clean, and npx @microsoft/vally-cli lint skills/aeon passes both checks (spec-compliance and valid file references).
• I have not dogfooded this inside GitHub Copilot yet, so I left that checklist box unchecked. The skill is a plain Agent Skill (Markdown, spec-compliant) and drives an instance through the gh CLI and the repo's ./aeon command, so it is agent-agnostic. Happy to make any changes reviewers want.
