hermes-plugin-evaluation

hermes-plugin-evaluation is a skill for Claude Code, Codex from AtlasOmnia/hermes-custom-pack. It costs 37 tokens per session (743 once invoked), scanned A, a copy of hermes-plugin-evaluation, MIT.

A checklist for assessing third-party Hermes Agent plugins or integrations before installing or using them. It examines code cost, service charges, data sharing, webhooks, tunnels, and changes to gateway behavior.

In plain words
What is it for?
Use it to inspect plugin repositories, licenses, setup files, billing requirements, network exposure, data flows, and operational risks.
Why use it?
It helps you decide whether an integration is safe and affordable before it touches the live Hermes gateway. It separates free plugin code from paid services the plugin may require.

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

hermes-plugin-evaluation 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.

Hermes Plugin Evaluation

Use this when the user asks about installing, trusting, pricing, or using a third-party Hermes Agent plugin or integration.

Goal

Give a practical go/no-go read before touching the live Hermes gateway. Separate:

  • Plugin code cost/license — whether the repository itself is public/open-source/free to install.
  • Service cost — required SaaS account, usage billing, phone/SMS/voice costs, model API costs, tunnels, hosted routing, or paid feature gates.
  • Operational risk — what data leaves Hermes, whether the plugin opens public webhooks/tunnels, and whether it modifies gateway behavior.

Fast evaluation workflow

  1. Load authoritative Hermes context first when the task involves Hermes plugins:
  • Load hermes-agent if available.
  • Prefer official Hermes docs for CLI syntax and plugin lifecycle.
  1. Inspect the repository without installing it:
  • README / docs
  • plugin.yaml
  • pyproject.toml, package.json, lockfiles
  • LICENSE, NOTICE, or equivalent
  • setup wizard files and after-install notes
  • tool definitions, platform adapter files, webhook/tunnel code
  1. Answer cost precisely:
  • Say “plugin appears free/public” only for the repo/installable code.
  • Do not infer the hosted service is free just because the plugin is public.
  • Identify paid dependencies: phone numbers, SMS/MMS, voice minutes, hosted tunnels, OpenAI/Anthropic/etc. APIs, storage, or managed accounts.
  1. Check for a public pricing page, but treat absence as unknown, not free:
  • If pricing is missing/404/gated, say “pricing not publicly obvious; confirm with vendor.”
  1. Report required credentials and data paths:
  • Required env vars/API keys.
  • Optional credentials that change cost or data flow.
  • Whether inbound messages/calls pass through vendor infrastructure.
  1. Recommend a safe rollout:
  • Test in a non-critical Hermes profile or disabled gateway first.
  • Avoid putting it on the main gateway until pricing, credentials, and data flow are understood.
  • Run plugin-specific doctor/diagnostics before enabling public channels.

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.
