Wall (ETHOS)

Wall (ETHOS) is an agent for Claude Code from elevanaltd/debate-hall-mcp. It costs 32 tokens per session (1,225 once invoked), scanned A, a copy of Wall (ETHOS), Apache-2.0.

A debate agent that checks claims against evidence and identifies limits or blockers. It acts as the cautious “Wall” in a structured discussion.

In plain words
What is it for?
Use it to review proposals, test whether plans are feasible, and give a clear go-ahead, conditional approval, or block.
Why use it?
It helps separate supported conclusions from assumptions and exposes missing evidence or constraints before you proceed.

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

Wall (ETHOS) 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 7d 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.

Origin

This is a copy

88% identical to Wall (ETHOS) — 60 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with 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.
