## Description

Monitor Polymarket and/or Kalshi prediction markets for 24h price moves, volume changes, fresh comments, and high-conviction alerts

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

> **${var}**, Platform selector with an optional single-market override:
> - **empty** (`""`), run **both** platforms from their watchlists.
> - `polymarket`, run Polymarket's whole watchlist (`skills/monitor-polymarket/watchlist-polymarket.md`).
> - `kalshi`, run Kalshi's whole watchlist (`skills/monitor-polymarket/watchlist-kalshi.md`).
> - `polymarket:<event-slug>`, one ad-hoc Polymarket event (e.g. `polymarket:us-x-iran-ceasefire-by`).
> - `kalshi:<event-ticker>`, one ad-hoc Kalshi event (e.g. `kalshi:KXGDP-26Q2`).

Read `memory/MEMORY.md` for context.
Read the last 2 days of `memory/logs/` to compare against previous readings and flag *new* movers (not repeats of yesterday's news).

## Why this skill exists

A table of prices isn't useful. An operator reading this notification wants to answer: **"is there a market worth forming a view on right now, and why?"** Every rule below exists to push output toward that question, suppress noise, rank by decision value, and demand one line of reasoning per alert. This skill covers two venues, **Polymarket** (crypto-native, CLOB + comments) and **Kalshi** (regulated, liquidity-weighted signals), and dispatches to the branch(es) the selector asks for.

## Dispatch

Parse `${var}` into a platform choice and an optional single-market override, then run the matching branch(es).

```bash
PLATFORM="both"   # both | polymarket | kalshi
SINGLE=""         # optional single event slug (Polymarket) or ticker (Kalshi)

case "${var}" in
  "")            PLATFORM="both" ;;
  polymarket)   PLATFORM="polymarket" ;;
  kalshi)       PLATFORM="kalshi" ;;
  polymarket:*) PLATFORM="polymarket"; SINGLE="${var#polymarket:}" ;;
  kalshi:*)     PLATFORM="kalshi";     SINGLE="${var#kalshi:}" ;;
  *)            # unrecognised prefix, don't guess a venue; fall back to both watchlists
                PLATFORM="both"; SINGLE=""
                echo "unrecognised selector '${var}', running both watchlists" ;;
esac
```
