What it does

Stocks is an agent skill from Luciole-Studio/Misaka-Agent. Stock quotes, history, search, compare, crypto via Yahoo.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/stocks_client.py`).

It sits in Business, Finance & HR, covering Stock and market analysis. The repository describes itself as: A multi-agent research system for the humanities and social sciences. The licence is MIT.

When your agent uses it

Tasks that involve Stock and market analysis

Example prompts

“/stocks”

Requirements

Python 3
A credential in ALPHA_VANTAGE_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 3bcf7a3. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- alphavantage.co
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- ALPHA_VANTAGE_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Stocks loads about 685 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 271 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~16
When it runs · the whole SKILL.md, loaded when a task matches: ~685

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

The full file from Luciole-Studio/Misaka-Agent at commit 3bcf7a3, republished under its MIT licence (© Luciole-Studio). 271 words, ~685 tokens.

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_cap and pe_ratio may return null on quote when Yahoo's crumb session isn't established. Set ALPHA_VANTAGE_KEY to backfill.
Add a small delay between bulk requests to avoid rate-limiting.
This is read-only — no order placement, no account integration.

Verification

python ~/.hermes/skills/finance/stocks/scripts/stocks_client.py quote AAPL

Returns a JSON object with symbol: "AAPL" and a numeric price field.
