Screenhand: Agent for Claude Code

.claude/agents/chaos.md

Chaos is an agent for Claude Code from manushi4/Screenhand. It costs 40 tokens per session (1,558 once invoked), scanned A, original, AGPL-3.0.

An agent for chaos engineering, the practice of deliberately causing failures to test whether software recovers correctly.

In plain words
What is it for?
Use it to test ScreenHand by injecting simultaneous failures, exhausting resources, corrupting state during operations, and checking recovery under load.
Why use it?
It exposes recovery problems that may only appear when several failures happen together or resources run low.

This is manushi4/Screenhand's own configuration. It tells Claude Code how to work on Screenhand 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 Screenhand 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

Chaos 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.

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.
