Hermes Agent is an AI assistant that learns from its use by creating and improving skills, retaining knowledge, searching past conversations, and adapting to its users. It is for people who want to run an agent through a terminal or messaging platforms while connecting it to different AI models and scheduled tasks.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.01754 |
| Opus 5.5 | $0.00007 | $0.00702 |
| Sonnet 5.5 | $0.00004 | $0.00351 |
| Haiku 4.5 | $0.00002 | $0.00175 |
Grade A, and why
blogwatcher scanned grade A with 1 finding 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.

Blogwatcher
Track blog and RSS/Atom feed updates with the blogwatcher-cli tool. Supports automatic feed discovery, HTML scraping fallback, OPML import, and read/unread article management.
Working with Hermes tools (read this first)
blogwatcher-cli is the feed database; Hermes tools do the automation around it:
- Recurring watch — use the cronjob tool's
monitorfield, not a bare schedule.monitorruns a script each tick and only wakes the agent when output changes: set it to a script that runsblogwatcher-cli scan >/dev/null 2>&1 && blogwatcher-cli articles(deterministic output; new articles = changed output = agent wakes with the diff injected). Unchanged ticks cost zero LLM calls. Setdeliverto route digests to a chat/channel; addcontinuity: trueso consecutive digests can dedupe. - Reading an article the user asks about:
web_extract([url])on the article URL fromblogwatcher-cli articles— do not re-scrape by hand. - One-off "watch this page for changes" without feed semantics: skip this skill; the cronjob tool's
monitorfield accepts an http(s) URL directly. - One-off read of a feed or a site's latest posts, nothing to install: the bundled
rss-feedsskill (scripts/feed.py read URL); blogwatcher earns its install when you track many feeds with read/unread state. - Company/competitor tracking with analysis and citations: prefer the
competitor-news-monitorskill; blogwatcher is the lighter raw-feed layer it can sit on.

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.

blogwatcher is a skill published in the GitHub repository NousResearch/hermes-agent (257,759 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 1,754 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
