XerahS: Instructions file for Claude Code

CLAUDE.md

XerahS CLAUDE.md is an instructions file for Claude Code from ShareX/XerahS. It costs 25 tokens per session, scanned A, original, GPL-3.0.

A set of instructions for Claude-compatible coding agents working with ShareX/XerahS, a screenshot and screen-recording tool.

In plain words
What is it for?
Helping an agent understand how to work on the ShareX/XerahS codebase. The input does not describe any more specific tasks.
Why use it?
It gives the agent guidance specific to that project instead of leaving the instructions undefined.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

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

XerahS CLAUDE.md 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 5d 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.

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.
