What it does

Tlon is an agent skill from tloncorp/tlon-apps. Read Tlon activity and message history; manage workspaces (Tlon groups), channels, Markdown notes, shared Bucket files, contacts, profiles, settings, and channel hooks; expose content publicly; share hosted-browser sessions and arrange secure form handoffs. Use for operating Tlon, not general product explanations or ordinary outbound messaging.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 140 other files, including scripts and reference files (for example `EXPANSION_PLAN.md`, `MONOREPO_PROPOSAL.md` and `README.md`).

It sits in Knowledge Management, covering Note-taking. The repository describes itself as: Native, web clients, and server for Tlon Messenger. The licence is MIT.

When your agent uses it

  • Not general product explanations
  • Ordinary outbound messaging

Example prompts

  • “/tlon”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 61e412a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (JavaScript, from the files we listed), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tlon loads about 1.1k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 88 tokens; SKILL.md has 558 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~88
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~10k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Read Tlon activity and message history; manage workspaces (Tlon groups), channels, Markdown notes, shared Bucket files, contacts, profiles, settings, and channel hooks; expose content publicly; share hosted-browser sessions and arrange secure form handoffs. Use for operating Tlon, not general product explanations or ordinary outbound messaging.

Operate Tlon

Use the tlon tool for Tlon data and administration. Read the task reference below before an unfamiliar workflow. For explanations of the app, use tlon-product-guide if available.

In Tlon requests, workspace means a group: create, join, rename, invite, and list workspaces using groups commands. Explicit requests about the agent’s files or paths refer to its filesystem workspace instead.

Invoke and discover

Tool arguments are argument strings, not shell scripts:

json
{"command":"help"}
{"command":"help notes"}
{"command":"help notes note-create"}

--help and -h also work. This help covers only commands in the Tlon index; other tools such as message, read, and write have their own tool schemas, not Tlon subcommands. Exact flags live in command help; inspect it instead of guessing a verb or copying flags from a different operation. If CLI usage shows tlon at the start, omit it in the tool's command argument.

There is no shell expansion, pipe, redirection, or stdin transport. Use write to create a content file and pass its filename. Relative paths resolve in the active agent workspace, just like read and write. Do not put $VARIABLE, a heredoc, or inline Markdown in a filename argument.

Choose the task reference

Resolve these links relative to this skill's discovered directory. Use the location in the available-skills listing; do not assume a particular installation path. Read only the reference needed for the task.

Read activity, search history, manage reactions or existing postsReading

Identity, delivery, and completion

  • Use returned group flags, channel nests, note IDs, and revisions. Display titles are not identifiers. Resolve ambiguous targets before writing.
  • Credentials are supplied by the runtime. Use the current account; do not collect access codes, print credentials, or switch to the owner's identity to work around permissions. Some documented commands, such as invite-link retrieval, have an explicit owner-bound behavior.
  • Use message for ordinary outbound messages and replies. For local media, upload first and pass the returned HTTPS URL; see the media reference.
  • Use groups create-owned to create a group for a user and make them an admin. Read the groups reference for the identity requirements.
  • Use notes for Markdown notebooks. Deprecated %diary management is unavailable through this tool; ask the owner to use /migrate <diary-nest> instead of attempting migration writes yourself.
  • Do not use LaTeX delimiters in note bodies or messages; use plain text/Unicode or code blocks.
  • Report a concrete failure if the task could not be completed. Verify the requested state before claiming success. A pending or host-confirmed write needs status/readback, not an immediate duplicate write.

When discovery fails

If this skill or a linked reference is unavailable, help and command help still provide local syntax. Report a missing installation resource rather than inventing a path. A permission failure or unsupported command is not a reason to bypass the tool through a shell, raw API, or the hosted browser. If neither tlon nor message covers the request, tell the user your Tlon tools do not support it yet and, where the Tlon app offers it, that they can do it there.

Can I use Tlon in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tloncorp/tlon-apps --skill tlon -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/tlon, .gemini/skills/tlon, .github/skills/tlon and .opencode/skills/tlon in your project.

What does Tlon need to run?

Going by SKILL.md and its folder, Tlon needs JavaScript for the scripts in its folder. Our summary lists: Node.js.

Does Tlon access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Tlon safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Tlon use?

Tlon is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Tlon use?

About 1.1k tokens (SKILL.md is roughly 4.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 9.4k tokens, read only when the agent opens those files.

What are the alternatives to Tlon?

Skills that share tags, products or a category with Tlon: Qmd (alsk1992/CloddsBot, 2.9k stars), Obsidian Canvas Boards (AgriciDaniel/claude-obsidian, 15k stars), LLM Wiki (lewislulu/llm-wiki-skill, 655 stars) and Para Memory Files (paperclipai/paperclip, 99k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
