What it does

Mqtt is an agent skill from SynchronetBBS/sbbs. Use when working with Synchronet's MQTT integration — discovering whether MQTT is enabled (the [MQTT] section of ctrl/main.ini, not sbbs.ini), reading broker address/port/credentials/TLS settings, connecting with mosquittosub/mosquittopub (anonymous, user+pass, or one of four TLS modes: CA, mTLS, PSK, SBBS-internal-CA), or interacting with the topic tree for monitoring (server/node status, node-output spying, action/, retained loginattempts/<IP and maxconcurrent/<IP, log streams …/log[/<N]) or controlling the BBS…

Its SKILL.md is about 5.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with JavaScript. The repository describes itself as: Mirror of gitlab.synchro.net/sbbs (don't submit pull requests here).

When your agent uses it

  • Working with Synchronets MQTT integration — discovering whether MQTT is enabled (the [MQTT] section of ctrl/main.ini
  • Reading broker address/port/credentials/TLS settings
  • Connecting with mosquittosub/mosquittopub (anonymous
  • One of four TLS modes: CA

Example prompts

  • “is MQTT enabled”
  • “s the broker address”
  • “subscribe to all sbbs logs”
  • “/mqtt”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. discover whether MQTT is enabled and how to connect
  2. connect with mosquitto_sub / mosquitto_pub

What it can do on your machine

Read from SKILL.md and the folder at commit d83fbe2. 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

    Shell commands in SKILL.md call:

    • node

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

  • Network

    Links to these hosts (documentation or services it may open):

    • wiki.synchro.net

    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

Mqtt loads about 5.6k tokens when it runs. Until then it costs about 241 tokens; SKILL.md has 2,052 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~241
When it runs · the whole SKILL.md, loaded when a task matches
~5.6k

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,052 words (~5,588 tokens).
