price-alert

price-alert is a skill for Claude Code, Codex from aeonfun/aeon. It costs 31 tokens per session (4,286 once invoked), scanned A, original, MIT.

A price monitor for a tracked token that sends an alert when it reaches a new all-time high, makes a sharp one-hour move, or crosses a chosen price target.

In plain words
What is it for?
Use it to watch token prices, register one or more dollar targets, and receive event-driven alerts for major moves.
Why use it?
It closes the delay between a significant market move and a notification. Normal price changes remain silent, avoiding routine alerts.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

price-alert 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 yesterday.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

No new secrets. Uses keyless DexScreener; falls back to WebFetch when a public `curl` GET is flaky (there is no network sandbox).

How it starts

The opening of the file, as written. The whole thing — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.

${var} — Optional. Pass one or more target_price levels (comma-separated USD numbers, scientific notation allowed) to fire a one-time alert when the price crosses any of them. Empty = only ATH and sharp-move gates run. Pass dry-run to skip notify (state still updates). Pass set-target:<price> — the shape the Telegram force-reply sends (step 7) — to register a target and get a one-line confirmation.

Today is ${today}. repo-pulse reports star/fork deltas once a day, and the other scheduled digests run at fixed hours. None of them tell the operator "the price just hit a new high" or "the token moved 28% in the last hour" — both are events that warrant attention the moment they happen, not 14 hours later in a daily digest. This skill closes that window.

Why this exists

Scheduled daily digests are calm summaries. Real moves need real-time signal. Three classes of move are worth a same-day ping:

  • New all-time high. The single most narrative-shaping price event a token can have. Worth marking on the timeline regardless of size.
  • Sharp 1h moves (±20%). Either a buyer wave or a liquidation cascade — both change what the operator does next (post about it, watch for follow-through, check the chart).
  • Operator-set target crossings. The operator may want to know when price clears $X (often a personal stretch goal or a level tied to a tweet/launch). One alert per target per direction.

Everything else is noise not worth a same-day ping.

Config

Reads:

  • memory/MEMORY.md "Tracked Token" section — the tracked token's contract/chain. If absent, exit silently.
  • memory/topics/price-alert-state.json — last-known ATH, last-alert timestamps per event type, target-crossing history. Created with defaults on first run.

Writes:

  • memory/topics/price-alert-state.json — updated state every run.
  • memory/logs/${today}.md — one log block per run, even on OK.
  • Notification via ./notify — only when a gate fires.

No new secrets. Uses keyless DexScreener; falls back to WebFetch when a public curl GET is flaky (there is no network sandbox).

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.
