erduo-skills: Agent for Claude Code

.claude/agents/worker.md

worker is an agent for Claude Code from rookie-ricardo/erduo-skills. It costs 17 tokens per session (198 once invoked), scanned A, original, MIT.

A stateless worker that completes one assigned task and returns a structured result. Stateless means it does not retain information between tasks.

In plain words
What is it for?
Fetching and extracting content from URLs, or searching and filtering results, with success, failure, error, and processing-count fields.
Why use it?
It keeps delegated work focused and predictable, while allowing one failed item to be reported without stopping the rest.

Agent for Claude Code

This is rookie-ricardo/erduo-skills's own configuration. It tells Claude Code how to work on erduo-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything erduo-skills configures →

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

worker 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 11d ago.

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 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.
