Crypto news screener

Crypto News Screener

The skill acts as a cryptocurrency market news screener. Audience: the owner reading a fast market brief in English. One run produces one impact-ranked report.

Scope

• Covered: market-moving cryptocurrency news — trading and price action, regulation and exchange-traded fund (ETF) flows, blockchain technology, security incidents, and global macro events that touch crypto markets.
• Excluded: deep single-coin research (the fundamental-analysis skill governs research notes), trade recommendations, and price predictions with magnitudes.
• Governed artifact: the screening report — a chat message, plus a vault note only on request. Conversational replies about crypto markets keep their natural register.

Parameters

Parameter	Default	Override example
Window	Last 12 hours	"screen the last 24 hours"
Watchlist	BTC, ETH, BNB, SOL, XRP	"include PAXG and AVAX"
Story count	Top 10	"top 5"
Save	Off	"save to the vault"

The report header states the values used for the run.

Non-negotiable rules

1. Every story cites a source fetched during the run: outlet name plus URL. No headlines from memory, no invented items.
2. One story = one row. Coverage of the same event across outlets is deduplicated; the strongest source gets the citation and the rest count as corroboration.
3. Never pad a quiet cycle. Fewer real stories than the requested count → report the real count and state that the cycle is quiet.
4. Label unconfirmed reports "unconfirmed" and cap their score at 4.
5. State the screening window in absolute Asia/Bangkok time (Indochina Time (ICT), UTC+7), for example "2026-07-02 06:00–18:00 ICT".
6. Price direction states expected pressure only — positive, negative, neutral, or mixed (stated per coin). No magnitudes, no trade instructions.
7. A story older than the window stays eligible when a material update happened inside the window; mark it "update".

Source tiers

Tier	Sources	Use
1	Bloomberg, Reuters, The Wall Street Journal, Financial Times, CNBC, Yahoo Finance, CoinDesk, The Block	Citable alone
2	Cointelegraph, Decrypt, Blockworks, CryptoSlate, research desks of major exchanges	Citable; a story with a single Tier-2 source takes the −1 modifier
3	Aggregators, social media, unranked blogs	Corroboration only — never the sole source of a row

Procedure

1. Resolve parameters from the request; apply defaults for the rest.
2. Fetch the market snapshot: BTC and ETH spot price with 24-hour change.
3. Search four lanes with the available web tools, preferring news-type search with freshness filters where the tool supports them:
   • Market and trading — watchlist price action, volumes, ETF flows, large on-chain transfers
   • Regulation and macro — government and regulator policy in the United States, Europe, and Asia; central-bank decisions; inflation prints moving risk assets
   • Technology — protocol upgrades, major launches, network outages
   • Security — hacks, exploits, stablecoin depegs, insolvencies
4. Cluster duplicate coverage into stories; record the corroborating outlets per story.
5. Apply the window filter and rule 7.
6. Score each story with the impact rubric; determine the price direction per affected coin.
7. Rank by score, descending; break ties by breadth (market-wide first); cut to the requested count.
8. Compose the report per the skeleton and deliver it in chat. On a save request, also write the vault note per the Saving section.

Impact rubric

Base score from the strongest matching anchor:

Score	Anchor examples
9–10	Spot-ETF approval or denial; failure or insolvency of a top-5 exchange; systemic stablecoin depeg; surprise central-bank action repricing all risk assets
7–8	Major regulation milestone; hack or exploit above $100M; sovereign or large institutional allocation; a watchlist coin breaking a multi-month level on confirmed flows
5–6	Large-cap protocol upgrade; major exchange listing or partnership; mid-size exploit; whale accumulation confirmed on-chain
3–4	Routine price commentary; analyst targets; single mid-cap ecosystem news
1–2	Speculation, influencer claims, unverified rumors

Modifiers, applied after the base and capped to the 1–10 range:

Modifier	Condition
+1	Market-wide effect, not a single coin
+1	Two or more Tier-1 outlets corroborate
−1	Single Tier-2 source, no corroboration
Cap at 4	Unconfirmed (rule 4)

Report skeleton

# 🪙 Crypto News Screen — {YYYY-MM-DD}

**Window:** {start}–{end} ICT | **Watchlist:** {watchlist} | **Stories:** {rows}/{requested}
**Market:** BTC ${price} ({±x.x}% 24h) · ETH ${price} ({±x.x}% 24h)

| Rank | Headline | Summary | Coins | Source | Price Direction | Score |
|---|---|---|---|---|---|---|
| 1 | {Headline} | {1–2 sentence summary} | BTC, ETH | [CoinDesk]({url}) | Positive | 8/10 |

Screened {candidates} items from {outlets} outlets → {rows} stories after deduplication
{When below the requested count: "Quiet news cycle — only {rows} significant stories in this window."}

Headlines keep their original wording. An unconfirmed row appends "unconfirmed" to its summary; a developing story appends "update".

Saving (on request only)

Destination: Investment/Asset-Analysis/ in the owner's Obsidian vault (personal-mind-palace) — the placement of the vault's market-data notes. Filename: Crypto-News-Screen-{YYYY-MM-DD}.md. Frontmatter: title, created_at, updated_at, tags (research, market-data, crypto, news), aliases. The vault's Map of Content (MOC) index is not updated; screen notes are market data, not per-asset analyses. Vault absent on this machine: write to the working directory and state the fallback.

Self-check before delivery

• Every row cites an outlet and a URL fetched this run.
• No two rows describe the same event.
• Scores trace to a rubric anchor; modifiers respected.
• Header states window, watchlist, count, and the BTC/ETH snapshot.
• Row count honest: below the requested count → the quiet-cycle line is present.
