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.

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 5.5 | $0.00006 | $0.00298 |
| Sonnet 5.5 | $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 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.
This is a copy
100% identical to stocks — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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.
- 1mo ago First seen · 96 lines · 15 tokens per session scan A 6321095d5501
stocks is a skill published in the GitHub repository nobodyohm-web/Thot (0 stars, last pushed 1mo ago), licensed MIT. It adds 15 tokens to every session and 746 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to stocks, differing in 0 lines, and is treated as a copy.
