Comms CLI (tdc)
Access Comms messaging via the tdc CLI. Use when the user asks about their Comms workspaces, threads, messages, or wants to interact with Comms in any way.
Setup
tdc auth login # OAuth login (standard write scopes)
tdc auth login --read-only # OAuth login with read-only scope
tdc auth login --full-access # OAuth login with delete/admin scopes
tdc auth login --callback-port <n># Override the local OAuth callback port (default 8766)
tdc auth login --json # Emit a JSON envelope for scripted / agent use
tdc auth login --ndjson # Emit an NDJSON envelope for scripted / agent use
tdc auth token # Save API token manually (prompts securely; scope unknown, assumed write-capable)
tdc auth status # Verify authentication + show mode
tdc auth status --json # Full status payload as JSON (--ndjson also supported)
tdc auth status --user <ref> # Target a specific stored account (id, id:<n>, or display name)
tdc --user <ref> auth <status|logout|token view|refresh-token view> # Equivalent to passing --user after the subcommand; other commands accept the flag but ignore it
tdc auth logout # Remove saved token and auth metadata
tdc auth logout --json # Emits `{"ok": true}` (--ndjson is silent)
tdc auth logout --user <ref> # Target a specific stored account; mismatched ref errors with ACCOUNT_NOT_FOUND
tdc auth token view # Print the saved token to stdout (pipe-safe; refuses if COMMS_API_TOKEN is set)
tdc auth token view --user <ref> # Print the saved token for a specific stored account
tdc auth refresh-token view # Print the saved OAuth refresh token to stdout (pipe-safe; OAuth logins only)
tdc auth refresh-token view --user <ref> # Print the saved OAuth refresh token for a specific stored account
tdc account [list|current|use <ref>|remove <ref>] # Manage stored accounts; all support --json/--ndjson
# current's payload is {id, label, authMode, authScope, source:"config"} | {source:"env"} | {source:"token-only"}
tdc auth login # Re-running auth login with a different OAuth grant adds a NEW account; default stays pinned unless none was set
tdc workspaces # List available workspaces
tdc workspace use <ref> # Set current workspace
tdc completion install # Install shell completions
tdc config view # Show the current CLI configuration file (token masked)
tdc config set <key> <value> # Set a user preference (e.g. unarchive-new-threads true)
tdc doctor # Diagnose CLI setup and environment issues
tdc update # Update CLI to latest version
tdc changelog # Show recent changelog entries
OAuth login uses Todoist OAuth for Comms access. The default grant can read Comms data and create/update content or messages. It does not include delete, channel management, or user/workspace write scopes; use tdc auth login --full-access only when needed. Stored auth uses the system credential manager when available. If secure storage is unavailable, tdc warns and falls back to ~/.config/comms-cli/config.json. COMMS_API_TOKEN always takes priority over the stored token.
In read-only mode (tdc auth login --read-only), commands that modify Comms data (reply, archive, react, delete, etc.) are blocked by the CLI. Externally provided tokens (COMMS_API_TOKEN or tdc auth token) are treated as unknown scope and assumed write-capable.
View by URL
tdc view <url> # View any Comms entity by URL
Routes automatically based on URL structure:
- Message URL →
tdc msg view - Conversation URL →
tdc conversation view - Thread+comment URL →
tdc thread view(comment ID extracted from URL) - Thread URL →
tdc thread view
URLs may use either https://comms.todoist.com/{workspaceId}/... or https://comms.todoist.com/a/{workspaceId}/....
All target command flags pass through (e.g. --json, --raw, --full).

--notify automatically resolves IDs: group IDs are routed to the groups API field, user IDs to recipients. No special syntax needed.

If a channel is not found in tdc channels, widen with broader listings such as tdc channels --scope public, then tdc channels --scope public --state all. Check tdc channels --help for other available filters.
tdc channel threads returns every thread in the channel; pagination filters (--limit, --cursor, --since, --until, --unread) are applied client-side after fetch. --archive-filter is applied server-side. Results are sorted newest-first by last activity. In --json / --ndjson, the response includes a nextCursor string (opaque) you can pass via --cursor to fetch the next page; NDJSON emits the cursor as a final { "_meta": true, "nextCursor": "..." } line.
For tdc channel members add/remove/set, refs accept user identifiers (id:N, email, name) or group:<ref>, which expands to the group's current members. Group expansion is one-shot — it is not a persistent link, so users added to the group later will not auto-join the channel. set replaces membership with the resolved set and is dry-run by default (pass --apply to mutate); it refuses to remove the acting user unless --include-self is passed.

Dry Run
Mutating commands accept --dry-run to preview the operation without making the change. Where a command performs pre-flight validation (e.g. fetching the target thread to check channel access or ownership), those checks still run in dry-run — only the mutating write is skipped. Commands that have no pre-flight validation parse the reference and print the preview without hitting the API. The preview is structured:
[dry-run] Would <action>:
<Key>: <resolved value>
...
Run without --dry-run to execute.
Reference System
Commands accept flexible references:
- Numeric IDs:
123orid:123 - Comms URLs: Full
https://comms.todoist.com/...URLs (parsed automatically) - Fuzzy names: For workspaces/users -
"My Workspace"or partial matches
Piping Input
Commands that accept content (thread create, thread reply, comment update, conversation reply, msg update) auto-detect piped stdin:
cat notes.md | tdc thread reply <ref>
tdc thread create <channel-ref> "Title" < body.md
echo "Quick reply" | tdc conversation reply <ref>
If no content argument is provided and no stdin is piped, the CLI opens $EDITOR for interactive input. In non-TTY environments (e.g. when called by an agent or in a pipeline), the editor is automatically skipped and the command fails fast with an actionable error message. Use --non-interactive to force this behavior even in a TTY, or --interactive to override auto-detection.
tdc thread mark-read also accepts thread refs from stdin, one per line:
printf "123\n456\n" | tdc thread mark-read --yes
