Validator (ETHOS Specialist)

Validator (ETHOS Specialist) is an agent for coding agents from elevanaltd/debate-hall-mcp. It costs 40 tokens per session (2,906 once invoked), scanned A, original, Apache-2.0.

A validation agent that tests proposals against evidence, constraints, and practical feasibility. It acts as the “Wall” specialist in a structured debate.

In plain words
What is it for?
Use it to audit claims, assess feasibility, identify missing evidence, and deliver a firm judgment about whether a plan should proceed.
Why use it?
It reduces the risk of accepting attractive ideas that lack support, violate requirements, or cannot work in practice.

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

Validator (ETHOS Specialist) 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.
