  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Entity Extraction is an agent skill from NxcoreAI/EverRoom. Extract searchable entities and a concise summary from a document for EverRoom knowledge routing.

Its SKILL.md is about 160 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: EverRoom - A workspace that remembers your projects, decisions, and sources.

Example prompts

  • “/entity-extraction”

What it can do on your machine

Read from SKILL.md and the folder at commit b0d58e5. 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.

    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

Entity Extraction loads about 158 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 19 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~158

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 19 words (~158 tokens).

“从资料中抽取人物、项目、主题、长期目标、议题和事件,并概括资料内容。同一实体只保留一个规范叫法,通用词不算实体。kind 只能是指定六类,salience 为 0 到 1,evidence 必须是资料中的短句,最多返回 10 个实体;没有实体时返回空数组。”
