README (SKILL.md)
Hacker News Daily
Fetch top stories from Hacker News with keyword filtering and caching.
Quick Start
python3 scripts/fetch_hn.py
Options
python3 scripts/fetch_hn.py --limit 5 # Return 5 stories
python3 scripts/fetch_hn.py --min-score 100 # Only stories with 100+ points
python3 scripts/fetch_hn.py --no-cache # Force fresh fetch
python3 scripts/fetch_hn.py --format json # JSON output
Proxy
Set HTTP_PROXY or HTTPS_PROXY environment variable if needed:
export HTTPS_PROXY=http://127.0.0.1:7890
python3 scripts/fetch_hn.py
Output
Text format (default):
📰 Hacker News 精选
1. [AI] OpenAI releases new model
🔗 https://...
👍 892 分 | 💬 234 评论
JSON format (--format json): Array of story objects with id, title, url, score, etc.
Caching
Results cached for 4 hours at ~/.cache/hn-daily/hn_cache.json. Use --no-cache to bypass.
Keywords
Default filter keywords: ai, llm, gpt, claude, openai, programming, python, rust, startup, machine learning, github, etc.
Usage Guidance
This skill appears to do only what it claims: make HTTP requests to the Hacker News API, filter results, and cache them locally. Before installing or running: 1) be aware it makes outbound network requests (ensure your environment permits this). 2) It respects HTTP_PROXY/HTTPS_PROXY/ALL_PROXY — if you use a proxy, that proxy will see the requests and responses. 3) It writes a cache file to ~/.cache/hn-daily/hn_cache.json (contains story data only); remove it if you don't want local caches. 4) The script uses the Python 'requests' library — install it in a controlled environment (virtualenv) if you're cautious. 5) The script prints story URLs (which may link to arbitrary external sites) — treat links as you normally would. If you need higher assurance, run the script in an isolated environment (container) or review/execute the Python file yourself before granting the skill access.
Capability Analysis
Type: OpenClaw Skill
Name: hn-daily
Version: 1.0.1
The skill bundle fetches and filters Hacker News top stories, aligning with its stated purpose. It uses standard Python libraries, accesses the legitimate Hacker News API, and stores cache files in a dedicated directory within `~/.cache`. The `SKILL.md` provides clear instructions without any prompt injection attempts. While the script reads proxy settings from environment variables (`HTTP_PROXY`/`HTTPS_PROXY`), this is a standard network configuration feature and does not indicate malicious intent or introduce a vulnerability within the skill itself, but rather utilizes existing environment settings. No evidence of data exfiltration, malicious execution, persistence, or obfuscation was found.
Capability Assessment
Purpose & Capability
Name/description (HN top stories, keyword filtering, caching) lines up with the included Python script and reference file which call the official Hacker News Firebase API and implement filtering/caching. No unrelated credentials, binaries, or system paths are requested.
Instruction Scope
SKILL.md instructs running scripts/fetch_hn.py and documents use of HTTP_PROXY/HTTPS_PROXY which the script reads. The script only performs HTTP requests to the Hacker News API, filters results, and writes a cache file. It does not read arbitrary user files or attempt to transmit data to unknown endpoints, but it does write cached output to ~/.cache/hn-daily/hn_cache.json (expected for caching).
Install Mechanism
This is an instruction-only skill with a small included script and no install spec. No downloads or third-party installation steps are declared. The script depends on the Python 'requests' library but does not attempt to install it.
Credentials
No required environment variables or credentials are declared. The script reads standard proxy env vars (HTTP_PROXY, HTTPS_PROXY, ALL_PROXY) described in SKILL.md — these are reasonable for networked tools but are environment inputs beyond the declared requires.env (which is empty). There are no secrets requested or stored.
Persistence & Privilege
The skill does not request permanent platform presence (always:false) and does not modify other skills or system-wide settings. Its only persistent footprint is a cache file under the user's home directory (~/.cache/hn-daily/hn_cache.json).
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install hn-daily - After installation, invoke the skill by name or use
/hn-daily - Provide required inputs per the skill's parameter spec and get structured output
