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.

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 | $0.00015 | $0.00746 |
| Opus 5 | $0.00008 | $0.00373 |
| Sonnet 5 | $0.00003 | $0.00149 |
| Haiku 4.5 | $0.00002 | $0.00075 |
Grade A, and why
stocks 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 8d 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.

How it starts
The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stocks Skill
Read-only market data via Yahoo Finance. Five commands: quote, search,
history, compare, crypto. Python stdlib only — no API key, no pip
installs. Yahoo's endpoint is unofficial and may rate-limit or change.
When to Use
- User asks for a current stock price (AAPL, TSLA, MSFT, ...)
- User wants to look up a ticker by company name
- User wants OHLCV history or performance over a date range
- User wants to compare several tickers side by side
- User asks for a crypto price (BTC, ETH, SOL, ...)
Prerequisites
Python 3.8+ stdlib only. Optional: set ALPHA_VANTAGE_KEY to enrich
market_cap, pe_ratio, and 52-week levels when Yahoo's crumb-protected
fields come back null. Free key: https://www.alphavantage.co/support/#api-key
How to Run
Invoke through the terminal tool. Once installed:
SCRIPT=~/.hermes/skills/finance/stocks/scripts/stocks_client.py
python $SCRIPT quote AAPL
All output is JSON on stdout — pipe through jq if you want to slice it.
Quick Reference
python $SCRIPT quote AAPL
python $SCRIPT quote AAPL MSFT GOOGL TSLA
python $SCRIPT search "Tesla"
python $SCRIPT history NVDA --range 6mo
python $SCRIPT compare AAPL MSFT GOOGL
python $SCRIPT crypto BTC ETH SOL
Commands
quote SYMBOL [SYMBOL2 ...]
Current price, change, change%, volume, 52-week high/low.
search QUERY
Find tickers by company name. Returns top 5: symbol, name, exchange, type.
history SYMBOL [--range RANGE]
Daily OHLCV plus stats (min, max, avg, total return %). Ranges: 1mo,
3mo, 6mo, 1y, 5y. Default: 1mo.
compare SYMBOL1 SYMBOL2 [...]
Side-by-side: price, change%, 52-week performance.
crypto SYMBOL [SYMBOL2 ...]
Crypto prices. Pass BTC (the script appends -USD automatically).
Pitfalls
- Yahoo Finance's API is unofficial. Endpoints can change or rate-limit without notice — if requests start failing, that's why.
market_capandpe_ratiomay return null onquotewhen Yahoo's crumb session isn't established. SetALPHA_VANTAGE_KEYto backfill.- Add a small delay between bulk requests to avoid rate-limiting.
- This is read-only — no order placement, no account integration.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

stocks is a skill published in the GitHub repository NousResearch/hermes-agent (242,680 stars, last pushed today), licensed MIT. It adds 15 tokens to every session and 746 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
