Overlaps with #9141 which also wires general plugin commands into main parser. May need reconciliation.

@alt-glitch I appreciate you consider this issue. Right now from main there is no way to register the general plugins CLI commands. I followed the docs here but never worked for me.

+1, reproducing this on latest main (commit b7ad3f478). Worth flagging that this gap got more visible after #16364 (the bundled google_meet plugin) merged on 2026-04-27 — that plugin uses register_cli_command() to expose hermes meet ... and ships with a README + SKILL.md documenting the CLI surface, but none of it is reachable end-to-end:

hermes plugins enable google_meet
hermes plugins list
# → google_meet: status=enabled, source=bundled
hermes meet install
# → hermes: error: argument command: invalid choice: 'meet'
#   (choose from 'chat', 'model', ..., 'dashboard', 'logs')

So a bundled plugin currently ships with its user-facing CLI dead on arrival, which I think bumps this above pure "plugin system internals" territory. Agent-facing tools (meet_join, meet_status, etc.) work fine because register_tool() is wired correctly in main.py — it's specifically register_cli_command() that has writers (hermes_cli/plugins.py:314) but no readers in hermes_cli/main.py. Repo-wide grep confirms: only discover_plugin_cli_commands() from plugins.memory ever feeds the top-level subparsers.

For anyone landing here looking for a workaround while this PR settles: plugins/google_meet/cli.py has its own __main__ block, so python -m plugins.google_meet.cli <subcommand> works as a drop-in for hermes meet <subcommand>. Same args, same handlers.

Re: reconciliation with #9141 — happy to help if it's the thing keeping this stalled. I can rebase against current main, run the test suite on Ubuntu 22.04, and post a clean diff if that's useful. Just let me know which approach to converge on (this PR's normalization + collision checks vs. #9141's leaner skip-on-conflict).

Closing as already fixed on main.

Triage notes (medium confidence):
origin/main hermes_cli/main.py:12511-12542 already does lazy plugin CLI discovery via _plugin_cli_discovery_needed(), wires subparsers, and tracks seen_plugin_commands to avoid collisions; register_cli_command exists in hermes_cli/plugins.py:387.

If you still see this on the latest version, please reopen with reproduction steps.
