Wall (ETHOS)

Wall (ETHOS) is an agent for coding agents from elevanaltd/debate-hall-mcp. It costs 32 tokens per session (1,232 once invoked), scanned A, original, Apache-2.0.

A debate agent that tests claims against evidence, identifies constraints, and gives a clear verdict such as proceed, proceed with conditions, or blocked.

In plain words
What is it for?
Use it to validate proposals, assess constraints, cite supporting evidence, flag violations, and decide whether work should proceed.
Why use it?
It helps separate supported conclusions from assumptions and makes missing evidence or invalid structures visible.

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 4d 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.

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.

Wall (ETHOS) is an agent published in the GitHub repository elevanaltd/debate-hall-mcp (8 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 1,232 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
