Sweeper review, all three points: - Placement: no new plugins/model-providers/ directory. The Token Plan profiles register from the existing alibaba plugin module — one module per vendor, matching how the kimi module carries both of its endpoint variants. Token Plan is the same vendor/service (Model Studio), same OpenAI-compatible protocol, its own key + endpoints; splitting to a standalone repo remains a 5-minute change if maintainers prefer. - Runtime coverage: TestRuntimeAlibabaRegionalAndTokenPlan exercises resolve_runtime_provider() for all four variants — provider, api_key, api_mode, base_url — alongside the existing zai/minimax/kilocode runtime regressions. - Docs: providers.md, environment-variables.md, cli-commands.md updated with the bundled variants and their env keys/base-url overrides.
