Core Supaterm CLI guide for controlling spaces, tab groups, tabs, panes, selectors, diagnostics, settings, licensing, and coding-agent integrations with sp.

  • SKILL.md covers Terminology, Fast Start and Deep-Dive References
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Core is an agent skill from supabitapp/supaterm. Core Supaterm CLI guide for controlling spaces, tab groups, tabs, panes, selectors, diagnostics, settings, licensing, and coding-agent integrations with sp. Read this before running Supaterm commands.

Its SKILL.md is about 980 tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `references/agent.md`, `references/connection-and-diagnostics.md` and `references/group.md`).

The repository describes itself as: a terminal for the coding agents age.

Example prompts

  • “/core”

What it can do on your machine

Read from SKILL.md and the folder at commit 87eaa09. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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

Core loads about 981 tokens when it runs, and up to ~8.7k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 407 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~981
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.7k

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 407 words (~981 tokens).

“Use sp to control Supaterm from a terminal already running inside Supaterm. Run sp skills get coding-agents before launching or prompting a coding agent.”
