What it does

Natural is an agent skill from NPC-Worldwide/npcpy. Render the provided prompt template with Jinja context and send it to the active NPC's LLM. The rendered text becomes the user prompt; the LLM response is placed in context['output'].

Its SKILL.md is about 160 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `render_and_send.py`).

It sits in AI & LLM Engineering, covering Prompt engineering and MCP servers. It works with Model Context Protocol, Ollama, Perplexity and Python. The repository describes itself as: The python library for research and development in NLP, multimodal LLMs, Agents, ML, Knowledge Graphs, and more. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit cd8324c. 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
Ships script files (Python), which the agent can run.
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

Natural loads about 161 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 39 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~48
When it runs · the whole SKILL.md, loaded when a task matches: ~161

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

The full file from NPC-Worldwide/npcpy at commit cd8324c, republished under its MIT licence (© NPC-Worldwide). 39 words, ~161 tokens.
