🧠 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

❌ Currently Unavailable

Data Acquisition Workflow

1. 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)
2. Parse with python3 -c "import json; data = json.load(open('/tmp/filename.json')); ..."
3. 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

1. Fetch HN front page — identifies the overall tech zeitgeist for the day
2. Fetch HN Ask HN — captures user needs, pain points, and demand signals
3. Fetch HN Show HN (recent, points>10) — captures new projects people are building
4. Fetch GitHub trending repos (last 7 days) — identifies what developers are excited about
5. Fetch additional sources if available (Reddit, Twitter, etc.)
6. Synthesize findings into the structured report
7. Save to file at /opt/data/hermes/idea-miner/idea-miner_{YYYYMMDD}.md
8. 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

1. HN Algolia URL encoding: The numericFilters parameter with > must use %3E not raw >. E.g. numericFilters=points%3E10
2. Reddit API blocked: Don't retry Reddit JSON API with this IP — it's consistently 403. Only retry if OAuth creds are configured.
3. 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.
4. 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.
5. 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.
6. No xurl installed: X/Twitter mining won't work unless xurl CLI is installed and OAuth'd.
7. 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.]
