Hermes WebUI is a browser-based interface for Hermes Agent, an autonomous agent that runs on a server, remembers what it learns, and can be accessed through terminals or messaging apps. Users employ it to chat with Hermes, manage sessions and settings, browse workspace files, and use the agent from a computer or phone. The catalogue instruction supports workflows for operating Hermes through its web interface.

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 | $0.01948 | $0.01948 |
| Opus 5.5 | $0.00779 | $0.00779 |
| Sonnet 5.5 | $0.00390 | $0.00390 |
| Haiku 4.5 | $0.00195 | $0.00195 |
Grade A, and why
hermes-webui AGENTS.md 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 1mo 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.

Onboarding and reinstall support
If the task involves install, reinstall, bootstrap, first-run onboarding,
provider setup, local model server setup, Docker onboarding, WSL onboarding, or
support for a failed first run, read docs/onboarding-agent-checklist.md
before running commands or inspecting logs.
Follow that checklist's safety rules:
- use isolated
HERMES_HOMEandHERMES_WEBUI_STATE_DIRfor trials unless the human explicitly asks to use real state - do not delete or overwrite a real
~/.hermesdirectory without explicit approval - do not print API keys, OAuth tokens, cookies, full
.envfiles, fullauth.jsonfiles, or password hashes - collect non-secret status and log evidence before recommending a fix
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.
