Hermes One is a desktop application for installing, configuring, and chatting with Hermes Agent, an AI assistant that uses tools, memory, skills, scheduling, and messaging integrations. It is for people who want to manage Hermes Agent through a graphical interface, and the catalogue entries support its workflows with skills, hooks, instructions, and settings.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.16691 |
| Opus 5.5 | $0.00018 | $0.06676 |
| Sonnet 5.5 | $0.00009 | $0.03338 |
| Haiku 4.5 | $0.00005 | $0.01669 |
Grade A, and why
hermes-agent 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.
