sample-plugin

sample-plugin is a skill for Claude Code, Codex from PyModel/pythinker-cli. It costs 28 tokens per session (157 once invoked), scanned A, original, Apache-2.0.

A demonstration plugin showing that add-on tools can be written in different programming languages.

In plain words
What is it for?
It includes a Python tool that generates an English greeting and a TypeScript tool that evaluates a mathematical expression.
Why use it?
It provides a small example of how a plugin can expose tools without requiring all tools to use the same language.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sample-plugin scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/calc.ts, scripts/greet.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Sample Plugin

A demo plugin with two tools in different languages, showing that plugin tools are language-agnostic.

Tools

Tool Language Description
py_greet Python Generate an English greeting
ts_calc TypeScript Evaluate a math expression

Usage

  • "greet Alice" -> use py_greet with name="Alice"
  • "what is 42 * 17 + 3" -> use ts_calc with expression="42 * 17 + 3"
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sample-plugin is a skill published in the GitHub repository PyModel/pythinker-cli (21 stars, last pushed 3d ago), licensed Apache-2.0. It adds 28 tokens to every session and 157 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
