Additional notes for reviewers

MegaLinter aggregates 100+ linters covering 69+ languages, 23+ formats and 21+ tooling formats.

The plugin lives at the repository root and ships:

• 4 skills under skills/ (megalinter, megalinter-setup, megalinter-check, megalinter-fix)
• 3 sub-agents (megalinter-watcher, megalinter-runner, megalinter-fixer)

Manifests: a root plugin.json conforming to Agent Plugins 1.0, plus .claude-plugin/ (also honored by Copilot) for the agent declarations.

No API key, credentials, or network service are required. The skills drive the public mega-linter-runner npm package and the MegaLinter Docker image.
