When to Use

User needs Yahoo Finance workflows, ticker discovery, quote checks, watchlist reviews, or fast market context before making a stock decision. Agent handles symbol search, single-name snapshots, multi-ticker briefings, and risk-aware thesis framing without pretending to place trades.

Architecture

Memory lives in ~/yahoo/. If ~/yahoo/ does not exist, run setup.md. See memory-template.md for structure.

~/yahoo/
├── memory.md        # Activation preferences, market scope, and answer style
├── watchlist.md     # Ranked tickers, benchmarks, and catalyst notes
├── briefing-log.md  # Saved pre-market, post-market, or event-driven briefs
└── decisions.md     # Thesis, invalidation, and review notes

Quick Reference

Load only the files that improve the current answer. Use the scripts when deterministic output is faster than manual browsing.

Topic	File
Setup and activation	`setup.md`
Local memory structure	`memory-template.md`
Command recipes	`commands.md`
Market briefing workflow	`market-playbook.md`
Thesis framing template	`thesis-card.md`
Risk guardrails	`risk-playbook.md`
Single-symbol snapshot script	`yahoo_quote.py`
Symbol and headline search script	`yahoo_search.py`
Multi-ticker briefing script	`yahoo_brief.py`

Requirements

python3
Outbound web access to finance.yahoo.com and Yahoo Finance search endpoints
User approval before creating or updating local watchlists or decision logs

Quick Start

python3 yahoo_search.py "apple"
python3 yahoo_quote.py AAPL
python3 yahoo_brief.py AAPL MSFT NVDA AMZN

Use the scripts for grounded snapshots, then layer judgment with market-playbook.md, thesis-card.md, and risk-playbook.md.

Operating Coverage

Fast quote check

Pull the current Yahoo Finance price panel, day move, and headline statistics for one symbol.
Use yahoo_quote.py when the user wants a quick tape read before deeper analysis.

Symbol resolution and headline scan

Resolve ambiguous company names, ETFs, ADRs, and similarly named tickers before analysis.
Use yahoo_search.py when the user says "Apple", "Nvidia", "QQQ", or anything that could map to multiple instruments.

Watchlist and market brief

Compare multiple names side by side, surface leaders and laggards, and flag extreme movers worth a second look.
Use yahoo_brief.py when the user wants a pre-market, post-market, or event-driven pass across a basket.

Core Rules

1. Resolve the exact symbol before making claims

Confirm the tradable instrument first: common stock, ADR, ETF, index, crypto pair, or forex pair.
Ambiguous names create fake analysis and wrong catalysts.
Use yahoo_search.py whenever the input is not already a clean ticker.

2. Match the workflow to the decision horizon

Separate quick quote checks, same-day tape reads, swing planning, and longer position reviews.
The same number means different things on an intraday trade than on a three-month thesis.
Start every answer with the user's time horizon if it changes the recommendation.

3. Separate tape, thesis, and trigger

Report what Yahoo shows now, what the thesis claims, and what evidence would validate or break it.
Price action alone is not a thesis.
Use thesis-card.md to convert commentary into a falsifiable setup.

4. Keep catalyst timing explicit

Mention the nearest catalyst window that could invalidate a calm-looking setup: earnings, macro releases, product events, or regulatory dates.
If there is no clear catalyst, say that the setup is mostly technical or mostly watchlist-only.
Use market-playbook.md to frame why the next time window matters.

5. Put risk controls ahead of opportunity

Position sizing, invalidation, liquidity, and volatility limits come before upside stories.
A good idea with undefined risk is still a bad trade.
Use risk-playbook.md before suggesting size, urgency, or conviction.

6. Treat local storage as opt-in continuity

Keep local memory limited to watchlists, recurring benchmarks, preferred answer style, and durable risk boundaries.
Do not create ~/yahoo/ silently for sensitive market context.
Save only what clearly improves the next Yahoo workflow.

7. Verify timestamp and market state every time

Read whether the number is at close, pre-market, post-market, or delayed.
Users misread stale prints as live confirmation all the time.
Quote answers must include the market-state context when Yahoo exposes it.

Common Traps

Analyzing the wrong ticker because the company name matched multiple instruments -> wrong catalyst map and wrong price history.
Treating a daily move as a thesis by itself -> momentum chasing without structure.
Ignoring whether Yahoo is showing close, pre-market, or after-hours data -> stale or misread entries.
Ranking a watchlist without catalyst timing -> busy output with no decision value.
Saving detailed holdings or account balances by default -> unnecessary privacy exposure.
Confusing a market brief with trade authorization -> the skill supports decisions but does not execute orders.

External Endpoints

Endpoint	Data Sent	Purpose
`https://finance.yahoo.com/quote/{symbol}`	ticker symbol in URL path	Current price panel and headline quote statistics
`https://query1.finance.yahoo.com/v1/finance/search`	query text, quote/news count	Symbol lookup and related headline search

No other data is sent externally.

Security & Privacy

Data that leaves your machine:

Ticker symbols or text search queries sent to Yahoo Finance pages and search endpoints

Data that stays local when the user opts in:

Watchlists, preferred benchmarks, briefing notes, and decision boundaries in ~/yahoo/

This skill does NOT:

Place broker orders or connect to brokerage accounts
Store credentials, account numbers, or tax documents
Create or update local files without user approval
Make undeclared network requests outside Yahoo Finance endpoints

Trust

By using this skill, ticker symbols and search queries are sent to Yahoo Finance. Only install if you trust Yahoo with that market lookup data.

Data Storage

All local state lives in ~/yahoo/ when the user wants continuity. Keep storage compact: watchlists, repeated benchmark sets, answer-style preferences, and thesis reviews. Avoid full holdings exports unless the user explicitly asks for local note-taking.
