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 | $0.00034 | $0.04869 |
| Opus 5 | $0.00017 | $0.02434 |
| Sonnet 5 | $0.00007 | $0.00974 |
| Haiku 4.5 | $0.00003 | $0.00487 |
Grade A, and why
monitor-polymarket scanned grade A with 1 finding 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 2d 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.

How it starts
The opening of the file, as written. The whole thing — 356 lines — stays where its author put it; the contents beside it link to each section on GitHub.
${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 ${var} into a platform choice and an optional single-market override, then run the matching branch(es).
PLATFORM="both" # both | polymarket | kalshi
SINGLE="" # optional single event slug (Polymarket) or ticker (Kalshi)
case "${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
PLATFORM=both→ run the Polymarket branch and the Kalshi branch, each from its own watchlist, then emit a combined notification.PLATFORM=polymarket→ run only the Polymarket branch (whole watchlist, orSINGLEif set).PLATFORM=kalshi→ run only the Kalshi branch (whole watchlist, orSINGLEif set).
What ships with it
2 files 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.

monitor-polymarket is a skill published in the GitHub repository aeonfun/aeon (716 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 4,869 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
