code-examples

A code-example generator that produces complete samples for APIs and software integrations in several programming languages, including cURL, JavaScript/Node.js, and Python.

In plain words
What is it for?
Use it to create SDK samples, API request examples, and integration instructions for developers.
Why use it?
It removes the need to translate an API description into working code yourself. The examples include setup, error handling, expected output, and safe handling of secrets.

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

code-examples 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 yesterday.

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

Multi-Language Code Example Generator

You create complete, working code examples in multiple programming languages.

Languages to support

Default languages (unless user specifies otherwise):

  1. cURL (always include)
  2. JavaScript/Node.js
  3. Python
  4. Go (if requested)

Example structure

Each example must include:

1. Installation (if using SDK)

npm install @yourapi/sdk

2. Complete code with imports

import { Client } from '@yourapi/sdk';

const client = new Client({
  apiKey: process.env.API_KEY
});

try {
  const response = await client.users.create({
    name: 'John Doe',
    email: '[email protected]'
  });

  console.log('User created:', response.id);
} catch (error) {
  console.error('Error:', error.message);
}

3. Expected output

User created: usr_abc123

Code quality rules

  • Complete imports and initialization
  • Error handling with try-catch
  • Environment variables for secrets (never hardcode API keys)
  • Helpful comments for non-obvious code
  • No pseudocode or // ... rest
  • No hardcoded API keys or secrets

Output format

## [Action Name]

### cURL

[example]

### JavaScript

[example]

### Python

[example]

Language-specific conventions

cURL

  • Use -X for method, -H for headers, -d for data
  • Show jq piping for response formatting when helpful
  • Use \ for line continuation

JavaScript/Node.js

  • Use import (ESM) by default, note CommonJS alternative
  • Use async/await over .then() chains
  • Use fetch or SDK client

Python

  • Use requests library or SDK
  • Include if __name__ == '__main__': block
  • Use f-strings for formatting
  • Show pip install command

Go

  • Include full package main with imports
  • Show go get command
  • Use net/http or SDK client
  • Include error checking (Go style)
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.

code-examples is a skill published in the GitHub repository techtrailhead/devrelskills (2 stars, last pushed 6mo ago), licensed MIT. It adds 26 tokens to every session and 511 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
