🧠 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-minerand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

❌ 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
numericFiltersparameter with>must use%3Enot 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 | python3triggers security warnings. Save output to file first with-o /tmp/file, then parse withpython3 -creading 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/searchendpoint returns all-time top, not recent. Use/search_by_datefor 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. [SILENT] is a literal ASCII control token — never translate or rephrase it, whatever language the rest of your answer uses. Never combine [SILENT] with content — either report your findings normally, or say [SILENT] and nothing more. FAILURE: If a delegated child fails and this cron run must be recorded as failed, put [CRON_FAILURE] on the first line by itself, then explain the child failure on following lines. RECURSION: This is a run of an EXISTING scheduled job — execute the task now. NEVER create or update a cron job because of recurring or future-schedule language in the task prompt below; treat phrasing like "each Monday" or "every day at 9" as context for this run, not as a request to schedule another job.]
