🧠 Idea Miner — Daily Creative Intelligence

Overview

Mines today's creative ideas, inspiration hotspots, and startup signals from public sources. Produces a structured Markdown report with demand signals, trending projects, and actionable insights.

The report is saved to /opt/data/hermes/idea-miner/idea-miner_{YYYYMMDD}.md and delivered to the configured destination (Telegram, etc.).

When to Use

Cron job for daily idea-mining runs (referenced by trender-idea-miner and 每日创意推送)
User asks: "what are today's hot ideas", "find me startup opportunities", "trending projects analysis"
Any session that needs to synthesize multi-source trend intelligence

Data Sources

✅ Available & Tested

Source	API Endpoint	Notes
HN Algolia (front page)	`https://hn.algolia.com/api/v1/search?tags=front_page&hitsPerPage=20`	Returns top stories with points
HN Algolia (Ask HN)	`https://hn.algolia.com/api/v1/search?tags=ask_hn&hitsPerPage=15`	Good for demand/need signals
HN Algolia (Show HN recent)	`https://hn.algolia.com/api/v1/search_by_date?tags=show_hn&numericFilters=points%3E10&hitsPerPage=12`	URL-encode `>` as `%3E`
HN Firebase (item detail)	`https://hacker-news.firebaseio.com/v0/item/{ID}.json`	Individual story metadata
GitHub Search (new repos)	`https://api.github.com/search/repositories?q=stars:%3E100+created:%3E{YYYY-MM-DD}&sort=stars&order=desc&per_page=10`	Header: `Accept: application/vnd.github.v3+json`, `User-Agent: HermesAgent/1.0`

❌ Currently Unavailable

Source	Issue
Reddit JSON API (`old.reddit.com`, `www.reddit.com`)	Blocked by Reddit (403 "whoa there, pardner") — needs OAuth credentials
Reddit pullpush.io (public archive)	Returns empty results from this IP
Google Trends RSS	Endpoint `trends.google.com/trendingsearches/daily/rss?geo=US` returns 404
Google Trends API	`trends.google.com/trends/api/dailytrends` returns 404
X/Twitter via xurl	`xurl` CLI not installed on this VPS

Data Acquisition Workflow

Use curl -s -o /tmp/filename.json -w '%{http_code}' to save to temp file first (avoids pipe-to-interpreter security blocks in cron mode)
Parse with python3 -c "import json; data = json.load(open('/tmp/filename.json')); ..."
Saved temp files are disposable — clean up or leave in /tmp

Report Format

The report uses Chinese (用户偏好) with the following sections:

Report Generation Steps

Fetch HN front page — identifies the overall tech zeitgeist for the day
Fetch HN Ask HN — captures user needs, pain points, and demand signals
Fetch HN Show HN (recent, points>10) — captures new projects people are building
Fetch GitHub trending repos (last 7 days) — identifies what developers are excited about
Fetch additional sources if available (Reddit, Twitter, etc.)
Synthesize findings into the structured report
Save to file at /opt/data/hermes/idea-miner/idea-miner_{YYYYMMDD}.md
Output the report as final response — the cron delivery system automatically delivers it

File Save Convention

Directory: /opt/data/hermes/idea-miner/
Filename: idea-miner_{YYYYMMDD}.md (e.g., idea-miner_20260727.md)
If the directory doesn't exist, create it

Common Pitfalls

HN Algolia URL encoding: The numericFilters parameter with > must use %3E not raw >. E.g. numericFilters=points%3E10
Reddit API blocked: Don't retry Reddit JSON API with this IP — it's consistently 403. Only retry if OAuth creds are configured.
Pipe-to-interpreter security blocks: In cron mode, curl | python3 triggers security warnings. Save output to file first with -o /tmp/file, then parse with python3 -c reading from file.
GitHub API rate limits: Without authentication, GitHub API is limited to 60 req/hr. For 10 repos + description parsing per run this is fine, but batch requests if expanding.
Show HN search prefers search_by_date: The /search endpoint returns all-time top, not recent. Use /search_by_date for recent Show HN posts.
No xurl installed: X/Twitter mining won't work unless xurl CLI is installed and OAuth'd.
Google Trends unavailable via simple curl: None of the documented public endpoints work (404). Skip silently.

Verification Checklist

[ ] HN front page fetched and parsed correctly
[ ] Ask HN fetched for demand signals
[ ] Show HN (recent) fetched for new projects
[ ] GitHub trending repos fetched
[ ] Report is structured with all tables and sections
[ ] File saved to correct path with date-stamped filename
[ ] Report output as final message (cron delivery takes over)

Related Scripts

The legacy shell script at /root/.hermes/scripts/idea-miner_daily.sh references a Python script at ~/idea-miner/idea_miner.py that no longer exists. The cron jobs now run Hermes agent directly with the prompt, bypassing the shell script. If the shell script is ever re-enabled, it needs to be updated.

Today's method reference: see references/today-methods.md for the exact curl/jq commands and data‑extraction steps used in this run.

The user has provided the following instruction alongside the skill invocation: [IMPORTANT: You are running as a scheduled cron job. DELIVERY: Your final response will be automatically delivered to the user — do NOT use send_message or try to deliver the output yourself. Just produce your report/output as your final response and the system handles the rest. SILENT: If there is genuinely nothing new to report, respond with exactly "[SILENT]" (nothing else) to suppress delivery. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more.]
