shux: Agent for Claude Code

.claude/agents/shux-vt-solid-qa.md

shux-vt-solid-qa is an agent for Claude Code from indrasvat/shux. It costs 71 tokens per session (2,979 once invoked), scanned A, original, no licence file.

A strict review agent for changes involving shux VT, terminal rasterisation, resizing, Unicode, pseudoterminals, pane sizing, captured output, or snapshot rendering. It requires pixel-level screenshot checking and only audits work.

In plain words
What is it for?
Use it before pull requests that change shux VT or related terminal rendering and output-handling code, including screenshot and snapshot behaviour.
Why use it?
It helps detect visual and terminal-compatibility regressions that ordinary tests may miss. Its hard-gate review is intended to catch issues before a pull request.

Agent for Claude Code

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

shux-vt-solid-qa 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 2mo 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.
