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 (opens browser, read-write)
tdc auth login --read-only        # OAuth login with read-only scope
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>  # 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 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

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

All target command flags pass through (e.g. --json, --raw, --full).

Inbox

tdc inbox --archive-filter archived # Show only done threads
tdc inbox --channel <filter>      # Filter by channel name (fuzzy)
tdc inbox --since <date>          # Filter by date (ISO format)
tdc inbox --limit <n>             # Max items (default: 50)

tdc thread update <ref> "New body" --json  # Update and return { id, content } as JSON
tdc thread update <ref> "New body" --json --full  # Update and return full thread as JSON

Default --notify for reply is EVERYONE_IN_THREAD, which may notify more people than intended. Before posting, confirm with the user whether specific people should be notified instead (via --notify <user-ids>). Options: EVERYONE, EVERYONE_IN_THREAD, or comma-separated ID refs.

--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.

Supported shortcodes: +1, -1, heart, tada, smile, laughing, thinking, fire, check, x, eyes, pray, clap, rocket, wave

Shell Completions

tdc completion install            # Install tab completions (prompts for shell)
tdc completion install bash       # Install for specific shell
tdc completion install zsh
tdc completion install fish
tdc completion uninstall          # Remove completions

Diagnostics

tdc doctor                        # Run local + network diagnostics
tdc doctor --offline              # Skip Comms and npm network checks
tdc doctor --json                 # JSON output with per-check results

Configuration

tdc config view                   # Pretty-printed config, token masked, labels actual token source
tdc config view --json            # Raw JSON, token masked
tdc config view --show-token      # Include the full token
tdc config set unarchive-new-threads true   # Persist: always unarchive new threads so they land in your Inbox
tdc config set unarchive-new-threads false  # Persist: keep Comms's default (thread auto-archived for author)

User preferences are stored under userSettings in the config file. Currently supported keys: unarchive-new-threads. The flag on tdc thread create (--unarchive / --no-unarchive) overrides this default per-invocation.

Update

tdc update                        # Update CLI to latest version

Global Options

--no-spinner               # Disable loading animations
--progress-jsonl           # Machine-readable progress events (JSONL to stderr)
--progress-jsonl=<path>    # Same, but write events to <path> instead of stderr
--progress-jsonl <path>    # Same as above (space-separated form also accepted)
--accessible               # Add text labels to color-coded output (also: TDC_ACCESSIBLE=1)
--non-interactive          # Disable interactive prompts (auto-detected when stdin is not a TTY)
--interactive              # Force interactive mode even when stdin is not a TTY

Output Formats

All list/view commands support:

--json    # Output as JSON
--ndjson  # Output as newline-delimited JSON (for streaming)
--full    # Include all fields (default shows essential fields only)

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: 123 or id:123
• Comms URLs: Full https://comms.todoist.com/... URLs (parsed automatically)
• Fuzzy names: For workspaces/users - "My Workspace" or partial matches

Piping Content

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.

Common Workflows

View by URL (auto-routes to the right command):
