example-skill

example-skill is a skill for Claude Code, Codex from kalinbogatzevski/captain-memo. It costs 13 tokens per session (150 once invoked), scanned A, original, Apache-2.0.

A sample skill that demonstrates how a skill can be organised into sections, code examples, usage notes, edge cases, and rules to avoid.

In plain words
What is it for?
It is for testing or explaining skill loading and for using as a template when writing skills.
Why use it?
It provides a small reference for learning the expected structure of a skill.

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

example-skill 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 today.

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

Example Skill

This is the introductory paragraph that captures the skill's purpose.

Architecture

The skill follows a layered architecture pattern. Layer 1 handles input, layer 2 transforms, layer 3 emits.

function transform(input: string): string {
  // intentional code block — must not be split
  return input.toUpperCase();
}

More architecture prose after the code block.

Usage

Invoke via the standard skill loader. The skill expects a string input.

Edge cases

Empty input → empty output. Null input → throws.

Anti-patterns

Don't bypass layer 2. Don't mutate inputs.

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.
