Tlon Skill

Use the tlon command for all Tlon operations.

Installation

npm (Node.js):

npm install @tloncorp/tlon-skill
tlon channels groups

Direct binary (no Node required):

curl -L https://registry.npmjs.org/@tloncorp/tlon-skill-darwin-arm64/-/tlon-skill-darwin-arm64-0.1.0.tgz | tar -xz
./package/tlon channels groups

Replace darwin-arm64 with darwin-x64 or linux-x64 as needed.

Configuration

CLI Flags (highest priority):

# Cookie-based auth (fastest - ship parsed from cookie name)
tlon --url https://your-ship.tlon.network --cookie "urbauth-~your-ship=0v..." <command>

# Code-based auth (requires url + ship + code)
tlon --url https://your-ship.tlon.network --ship ~your-ship --code sampel-ticlyt-migfun-falmel <command>

# Or load from a JSON config file
tlon --config ~/ships/my-ship.json <command>

Config file format:

// Cookie-based (ship derived from cookie)
{"url": "...", "cookie": "urbauth-~ship=..."}

// Code-based
{"url": "...", "ship": "~...", "code": "..."}

Environment Variables:

# Cookie-based (ship derived from cookie)
export URBIT_URL="https://your-ship.tlon.network"
export URBIT_COOKIE="urbauth-~your-ship=0v..."

# Code-based
export URBIT_URL="https://your-ship.tlon.network"
export URBIT_SHIP="~your-ship"
export URBIT_CODE="sampel-ticlyt-migfun-falmel"

OpenClaw: If configured with a Tlon channel, credentials load automatically.

Resolution order: CLI flags → TLON_CONFIG_FILE → URL + COOKIE → URL + SHIP + CODE → --ship with cache → OpenClaw config → cached ships (auto-select if only one)

Cookie vs Code:

• Cookie-based: Uses pre-authenticated session cookie. Ship is parsed from the cookie name (urbauth-~ship=...). Fastest option.
• Code-based: Performs login to get session cookie. Requires URL + ship + code.

You can provide both cookie and code — cookie is used first, code serves as fallback if cookie expires.

Cookie Caching

The skill automatically caches auth cookies to ~/.tlon/cache/<ship>.json after successful authentication. This makes subsequent invocations much faster by skipping the login request.

How it works:

# First time - authenticates and caches
$ tlon --url https://zod.tlon.network --ship ~zod --code abcd-efgh contacts self
~zod
Note: Credentials cached for ~zod. Next time just run: tlon <command>

# After that - no flags needed (if only one cached ship)
$ tlon contacts self
~zod

# With multiple cached ships - specify which one
$ tlon --ship ~zod contacts self
$ tlon --ship ~bus contacts self

Cache behavior:

• Cached cookies are URL-specific (won't use a cookie for the wrong host)
• If only one ship is cached, it's auto-selected (no flags needed)
• If multiple ships are cached, you'll be prompted to specify with --ship
• The skill reminds you when you pass credentials that aren't needed

Clear cache: rm ~/.tlon/cache/*.json

Multi-Ship Usage

If you have credentials for multiple ships, you can use this skill to operate on behalf of any of them. This is useful for:

• Managing multiple identities — switch between ships without changing environment variables
• Bot operations — act as a bot ship while authenticated as yourself
• Moon management — operate moons from their parent planet

Simply pass the target ship's credentials via CLI flags:

# Post to a channel as ~other-ship
tlon --url https://other-ship.tlon.network --ship ~other-ship --code their-access-code \
  posts send chat/~host/channel "Hello from other-ship"

# Or keep credentials in config files
tlon --config ~/ships/bot.json channels groups
tlon --config ~/ships/moon.json contacts self

Commands

Activity

Check recent notifications and unread counts. Ships are shown with nicknames when available.

tlon activity mentions --limit 10   # Recent mentions (max 25)
tlon activity replies --limit 10    # Recent replies (max 25)
tlon activity all --limit 10        # All recent activity (max 25)
tlon activity unreads               # Unread counts per channel

Channels

List and manage channels. DMs and group DMs show nicknames when available.

tlon channels dms                                          # List DM contacts (with nicknames)
tlon channels group-dms                                    # List group DMs (clubs, with nicknames)
tlon channels groups                                       # List subscribed groups
tlon channels all                                          # List everything
tlon channels info chat/~host/slug                         # Get channel details
tlon channels update chat/~host/slug --title "New Title"   # Update metadata
tlon channels delete chat/~host/slug                       # Delete a channel

# Writers (who can post)
tlon channels add-writers chat/~host/slug admin member     # Add write access
tlon channels del-writers chat/~host/slug member           # Remove write access

# Readers (who can view - requires group flag)
tlon channels add-readers ~host/group chat/~host/slug admin    # Restrict viewing
tlon channels del-readers ~host/group chat/~host/slug admin    # Open viewing

Notes on permissions:

• Empty writers list = anyone in the group can post (default for chat)
• Empty readers list = anyone in the group can view (default)
• Diaries default to admin-only writers
• Roles must exist in the group (use tlon groups add-role first)

Contacts

Manage contacts and profiles.

tlon contacts list                                   # List all contacts
tlon contacts self                                   # Get your own profile
tlon contacts get ~sampel                            # Get a contact's profile
tlon contacts sync ~ship1 ~ship2                     # Fetch/sync profiles
tlon contacts add ~sampel                            # Add a contact
tlon contacts remove ~sampel                         # Remove a contact

Hooks

Manage channel hooks — functions that run on triggers (posts, replies, reactions, crons).

# List and inspect
tlon hooks list                                          # List all hooks
tlon hooks get 0v1a.2b3c4                                # Get hook details and source

# Manage hooks
tlon hooks add my-hook ./hook.hoon                       # Add a new hook from file
tlon hooks edit 0v1a.2b3c4 --name "New Name"             # Rename a hook
tlon hooks edit 0v1a.2b3c4 --src ./updated.hoon          # Update source
tlon hooks delete 0v1a.2b3c4                             # Delete a hook

# Configure for channels
tlon hooks order chat/~host/slug 0v1a 0v2b 0v3c          # Set execution order
tlon hooks config 0v1a chat/~host/slug key1=val1         # Configure hook instance

# Scheduled execution
tlon hooks cron 0v1a ~h1                                 # Run hourly (global)
tlon hooks cron 0v1a ~m30 --nest chat/~host/slug         # Run every 30m for channel
tlon hooks rest 0v1a                                     # Stop cron job

Notes:

• Hook IDs are @uv format (e.g., 0v1a.2b3c4...)
• Schedules use @dr format: ~h1 (1 hour), ~m30 (30 minutes), ~d1 (1 day)
• Hooks run in order when triggered; use order to set priority
• Use config to pass channel-specific settings to a hook instance

Writing Hooks: See references/hooks.md for full documentation on writing hooks, including:

• Event types (on-post, on-reply, cron, wake)
• Bowl context (channel, group, config access)
• Effects (channel actions, group actions, scheduled wakes)
• Config handling with clam (;;)

Examples: See references/hooks-examples/ for starter templates:

• auto-react.hoon — React to new posts with emoji
• delete-old-posts.hoon — Cron job to clean up old messages
• word-filter.hoon — Block posts containing banned words

Messages

Read and search message history. Authors are shown with nicknames when available.

tlon messages dm ~sampel --limit 20                      # DM history (max 50)
tlon messages channel chat/~host/slug --limit 20         # Channel history (max 50)
tlon messages search "query" --channel chat/~host/slug   # Search messages

Options: --limit N, --resolve-cites

DMs

Manage direct messages.

# Group DMs (clubs)
tlon dms send <club-id> "hello"                          # Send to group DM
tlon dms reply <club-id> ~author/170.141... "reply"      # Reply in group DM

# Management
tlon dms react ~sampel ~author/170.141... "👍"           # React to a DM
tlon dms unreact ~sampel ~author/170.141...              # Remove reaction
tlon dms delete ~sampel ~author/170.141...               # Delete a DM
tlon dms accept ~sampel                                  # Accept DM invite
tlon dms decline ~sampel                                 # Decline DM invite

Expose

Publish Tlon content to the clearweb via the %expose agent.

tlon expose list                                         # List all exposed content
tlon expose show chat/~host/slug/170.141...              # Expose a post publicly
tlon expose hide chat/~host/slug/170.141...              # Hide an exposed post
tlon expose check diary/~host/blog/170.141...            # Check if a post is exposed
tlon expose url diary/~host/blog/170.141...              # Get the public URL

Cite path formats:

• Simplified: chat/~host/channel/170.141... (auto-expands)
• Full: /1/chan/chat/~host/channel/msg/170.141...

Channel kinds map to content types: chat→msg, diary→note, heap→curio

Posts

Manage channel posts (reactions, edits, deletes).

tlon posts react chat/~host/slug 170.141... "👍"         # React to a post
tlon posts unreact chat/~host/slug 170.141...            # Remove reaction
tlon posts edit chat/~host/slug 170.141... "New text"    # Edit with plain text
tlon posts edit diary/~host/slug 170.141... --title "T" --image <url> --content rich.json  # Edit notebook
tlon posts delete chat/~host/slug 170.141...             # Delete a post

Edit options for notebooks: --title, --image (cover URL), --content (Story JSON file for rich formatting).

Notebook

Post to diary/notebook channels.

tlon notebook diary/~host/slug "Title"                   # Post with no body
tlon notebook diary/~host/slug "Title" --content rich.json  # Post with Story JSON
tlon notebook diary/~host/slug "Title" --image <url>     # Post with cover image

The --content file should be Story JSON format (array of verses with headers, code blocks, formatting). See the Story types in tlon-apps.

Upload

Upload images to Tlon storage.

tlon upload https://example.com/image.png    # Upload image from URL

Returns the uploaded image URL for use in posts, profiles, etc.

tlon settings set <key> <json-value>                     # Set a value
tlon settings delete <key>                               # Delete a setting

# DM allowlist
tlon settings allow-dm ~ship                             # Add to DM allowlist
tlon settings remove-dm ~ship                            # Remove from allowlist

# Channel controls
tlon settings allow-channel chat/~host/slug              # Add to watch list
