What it does

Aggregating Crypto News is an agent skill from jeremylongshore/tons-of-skills-marketplace. Aggregate breaking cryptocurrency news from 50+ sources including CoinDesk, CoinTelegraph, The Block, and Decrypt. Use when needing to monitor crypto market news, track announcements, or find coin-specific updates. Trigger with phrases like "get crypto news", "latest Bitcoin headlines", "DeFi announcements", "scan for breaking news", or "check crypto updates".

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including scripts and reference files (for example `ARD.md`, `PRD.md` and `config/settings.yaml`). Compatibility notes: Designed for Claude Code

It sits in Business, Finance & HR, covering Crypto and DeFi analysis. It works with Bitcoin. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Needing to monitor crypto market news
  • Track announcements
  • Find coin-specific updates
  • With phrases like get crypto news

Example prompts

  • “get crypto news”
  • “latest Bitcoin headlines”
  • “DeFi announcements”
  • “/aggregating-crypto-news”

Requirements

  • Python 3
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Bash(crypto:news-*)

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Python 3.8+ installed
  2. Dependencies: pip install feedparser requests
  3. Internet connectivity for RSS feed access

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash(crypto:news-*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 5 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • coindesk.com
    • feedparser.readthedocs.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Aggregating Crypto News loads about 1.2k tokens when it runs, and up to ~5.7k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 218 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Aggregating Crypto News

Overview

Aggregate cryptocurrency news from 50+ authoritative sources via RSS feeds with real-time scanning, coin/category filtering, and relevance scoring.

Prerequisites

  1. Python 3.8+ installed
  2. Dependencies: pip install feedparser requests
  3. Internet connectivity for RSS feed access

Instructions

  1. Assess user intent - determine filters needed:

    • General news: no filters, use defaults
    • Coin-specific: extract symbol (BTC, ETH, etc.)
    • Category-specific: extract category (defi, nft, regulatory, etc.)
    • Time-specific: extract window (1h, 4h, 24h, 7d)
  2. Run the aggregator with appropriate filters:

    bash
    # Default scan (top 20, past 24h, relevance sorted)
    python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py
    
    # Coin-specific scan
    python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --coin BTC --period 4h
    
    # Category filter
    python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --category defi --top 30
    
    # Multiple filters
    python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --coin ETH --category defi --period 24h --top 15
  3. Export results for downstream processing:

    bash
    python ${CLAUDE_SKILL_DIR}/scripts/news_aggregator.py --format json --output news.json
  4. Present results to the user:

    • Show source, title, age, and relevance score
    • Highlight market-moving keywords if present
    • Provide links for full articles
    • Summarize meta information (sources checked, articles found)

Output

Table showing articles ranked by relevance score (0-100) based on market-moving keyword detection, source authority, and recency:
