XerahS: Skill for Claude Code

.ai/skills/diagnostics-knowledge-base/SKILL.md

diagnostics-knowledge-base is a skill for Claude Code, Codex from ShareX/XerahS. It costs 60 tokens per session (1,695 once invoked), scanned A, original, GPL-3.0.

A skill for working with an XerahS crash-report knowledge base hosted on Neon, a managed database service. It handles the fix queue, shared crash signatures, user diagnostics, and recorded fixes when the task names them.

In plain words
What is it for?
Use it to query, import, annotate, or record fixes in that named crash-report knowledge base.
Why use it?
It provides a defined place to query or record shared crash information instead of treating unrelated diagnostics as ordinary project work. The description does not specify other capabilities.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

This is ShareX/XerahS's own configuration. It tells Claude Code and Codex 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

diagnostics-knowledge-base 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.

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.
