What it does

Menus is an agent skill from SynchronetBBS/sbbs. Use when authoring or modifying Synchronet Terminal Server display/menu files — anything in text/, text/menu/, mods/text/, mods/text/menu/, data/subs/<code., data/dirs/<code.. Covers Ctrl-A (^A) attribute codes, @-code message variables, the file-extension priority by terminal type (rip/ans/mon/asc/msg/seq/utf8), .Xcol/.cX width variants, language overlays, security gating, mouse hotspots, and the C++/JS/Baja entry points that render these files. For the runtime string database (ctrl/text.dat, ctrl/text.ini…

Its SKILL.md is about 8k 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 C++. The repository describes itself as: Mirror of gitlab.synchro.net/sbbs (don't submit pull requests here).

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:
- git
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

Menus loads about 8k tokens when it runs. Until then it costs about 225 tokens; SKILL.md has 3,131 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~225
When it runs · the whole SKILL.md, loaded when a task matches: ~8k

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 3,131 words (~7,969 tokens).
