Test Red-DiscordBot cogs via downloader

Exercises cogs installed through Red's downloader by cloning a repo (local or remote), installing the targets, and running RPC smoke tests.

Inputs

Input	Required	Default	Description
token	✅	—	Token injected into the downloader-driven redbot run so the bot can authenticate with Discord.
cog_paths	❌	—	Comma-separated list of local cog directories to mirror into the temporary downloader repo; leave empty to auto-discover (local) or test every cog in the remote repo.
repo_name	❌	test-repo	Display name passed to the downloader helpers and logs; defaults to 'test-repo'.
repo_url	❌	—	Remote Git repository cloned before invoking downloader; when blank the action builds a throwaway repo from the provided cog_paths.
repo_branch	❌	—	Branch or ref to checkout when repo_url is provided; blank means use the default branch advertised by the remote.
rpc_port	❌	6133	TCP port exposed via --rpc-port; defaults to 6133 when not specified.

Usage

Minimal invocation that auto-discovers cog folders (bz-cogs/.github/workflows/check-cogs.yml):

- name: Test cogs via Downloader
  uses: nntin/d-flows/actions/test-red-discordbot-downloader@v1
  with:
    token: ${{ secrets.DISCORD_BOT_TOKEN }}
    # Leave cog_paths empty to let the action probe every cog in the repo

Exercise cogs from a remote repository/branch (SeaCogs/.forgejo/workflows/actions.yaml):

- name: Test Cogs
  uses: nntin/d-flows/actions/test-red-discordbot-downloader@v1
  with:
    token: ${{ secrets.DISCORD_BOT_TOKEN }}
    repo_url: ${{ forge.server_url }}/${{ forge.repository }}
    repo_branch: ${{ forge.event_name != 'pull_request' && forge.event_name != 'pull_request_target' && forge.ref_name || forge.head_ref }}
