NousResearch/hermes-agent#17751 (merged 2026-04-30) shipped a
comprehensive pluggable-platform system with:
- ctx.register_platform(name, label, adapter_factory, check_fn, ...)
- Open Platform enum (Platform('molecule') creates a pseudo-member
via _missing_() when the platform_registry knows about it)
That supersedes my upstream PR #18775 (which used a narrower
register_platform_adapter shape with a closed enum + custom
PluginPlatformIdentifier). Closing #18775 as redundant.
This plugin previously coupled to my fork's API. Migration:
- __init__.py register() now prefers ctx.register_platform when
available; falls back to ctx.register_platform_adapter on legacy
forks (template-hermes' baked-in fork until it migrates).
- adapter.py constructs Platform(name) when the enum accepts
'molecule', else falls back to PluginPlatformIdentifier(name).
Same wheel installs cleanly on stock hermes-agent (post-#17751)
AND on the legacy template-hermes fork build. Removed the test
stub of PluginPlatformIdentifier; tests now stub the open-enum
Platform shape with the same _missing_() behavior the upstream
ships.
