At a glance

This skill should be used when the user invokes "/select" to open one or more files in Emacs and select a region relevant to the current discussion via emacsclient.

  • Invokes /select to open one

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • More files in Emacs and select a region relevant to the current discussion via emacsclient

What it does

Select is an agent skill from xenodium/emacs-skills. This skill should be used when the user invokes "/select" to open one or more files in Emacs and select a region relevant to the current discussion via emacsclient.

Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

The repository describes itself as: Emacs skills for coding agents.

When your agent uses it

  • Invokes /select to open one
  • More files in Emacs and select a region relevant to the current discussion via emacsclient

Example prompts

  • “/select”
  • “/select”

What it can do on your machine

Read from SKILL.md and the folder at commit a158238. 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

Select loads about 463 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 187 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~463

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 187 words (~463 tokens).

“Open one or more files in Emacs and select (activate the region around) the code or text most relevant to the current discussion using emacsclient --eval. This allows the user to immediately act on the selection: narrow, copy, refactor, comment…”
