# Yahoo Finance — Printing Press CLI

## Prerequisites: Install the CLI

This skill drives the `yahoo-finance-pp-cli` binary. **You must verify the CLI is installed before invoking any command from this skill.** If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to `$HOME/.local/bin` on macOS/Linux and `%LOCALAPPDATA%\Programs\PrintingPress\bin` on Windows:
   ```bash
   npx -y @mvanhorn/printing-press-library install yahoo-finance --cli-only
   ```
2. Verify: `yahoo-finance-pp-cli --version`
3. Ensure the reported install directory is on `$PATH` for the agent/runtime that will invoke this skill.

If the `npx` install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.5 or newer):

```bash
go install github.com/mvanhorn/printing-press-library/library/commerce/yahoo-finance/cmd/yahoo-finance-pp-cli@latest
```

If `--version` reports "command not found" after install, the runtime cannot see the binary directory on `$PATH`. Do not proceed with skill commands until verification succeeds.

## When to Use This CLI

Reach for this CLI when an agent needs Yahoo Finance market data with deterministic JSON output, a local store that compounds across calls (portfolio, watchlist, history cache), or a working session from a rate-limited host. It is the only Yahoo Finance tool that joins your cost basis with live data and survives a 429 via a Chrome cookie fallback.

## When Not to Use This CLI

Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

## Unique Capabilities

These capabilities aren't available in any other tool for this API.

### Local state that compounds
- **`portfolio perf`** — Track YTD / 1Y / all-time returns on your holdings with cost basis, dividends, and current price baked in.

  _Reach for this when an agent needs to report 'how is my user's portfolio doing this year' — no single Yahoo Finance endpoint encodes cost basis._

  ```bash
  yahoo-finance-pp-cli portfolio perf --agent
  ```
- **`digest`** — One command: overnight news + biggest movers + earnings today + ex-div dates for everything on your watchlist.

  _Use as a single agent call for a 'daily market briefing' across a named set of tickers — replaces 4+ separate endpoint calls._

  ```bash
  yahoo-finance-pp-cli digest --watchlist tech --agent
  ```
- **`portfolio dividends`** — See total dividend income for the year, per-holding breakdown, and yield on cost.

  _Reach for this when the user asks 'how much have I earned in dividends this year' or 'what's my real yield on my JNJ position'._

  ```bash
  yahoo-finance-pp-cli portfolio dividends --year 2026 --agent
  ```
