Providers

Agent Plugin Compiler includes five adapters. Each adapter consumes the same validated plugin model and declares exact-file ownership for its host manifest. The shared renderer owns skills/** separately.

Built-in output

ID	Host	Manifest paths
claude	Claude plugin	.claude-plugin/plugin.json, .claude-plugin/marketplace.json
codex	Codex plugin	.codex-plugin/plugin.json
copilot	GitHub Copilot CLI	plugin.json
gemini	Gemini CLI extension	gemini-extension.json
kimi	Kimi Code CLI plugin	kimi.plugin.json

Claude emits both its plugin manifest and local marketplace manifest. Codex and Kimi point at the generated skills/ directory. Copilot and Gemini discover the root skill tree by host convention.

Provider schemas and fields belong to their respective hosts. The compiler's conformance tests pin the external formats implemented by this release.

Default selection

Declare defaults in the authored manifest:

providers:
  - claude
  - codex

An empty list requests shared skills without built-in provider manifests.

One-run override

The CLI override replaces the manifest list; it does not add to it:

plugin-compiler compile --provider copilot,gemini,kimi

Use --no-providers for an explicit empty override. The Node.js interface uses the same rule: omit providers for manifest defaults, pass a list to replace them, or pass [] for shared skills only.

Custom adapters

Programmatic consumers can create an isolated ProviderAdapterRegistry and register another adapter. Custom provider IDs use lowercase letters, digits, and hyphens, beginning with a letter.

An adapter must declare stable exact-file paths. Complete-tree ownership is rejected so a provider cannot claim an open-ended repository directory.

Next: use provider constants through the Node.js interface, or review the generated output model.
