Configuration Files

This skill uses the following configuration files:

| File | Purpose | |------|---------| | sources.json | Source configuration, priorities, scrape methods | | cache.json | Cached data, historical stats, deduplication fingerprints |

Execution Process Details

Phase 1: Initialization

Steps:
  1. Determine date (user argument or current date)
  2. Read sources.json for source configurations
  3. Read cache.json for historical data
  4. Create output directory NewsReport/
  5. Check if a partial report exists for today (append mode)

Phase 2: Dispatch SubAgents

Strategy: Parallel dispatch, batch execution, early stopping mechanism

Wave 1 (Parallel):
  - Worker A: Tier1 Batch A (HN, HuggingFace Papers)
  - Worker B: Tier1 Batch B (OneUsefulThing, Paul Graham)

Wait for results → Evaluate count

If < 15 high-quality items:
  Wave 2 (Parallel):
    - Worker C: Tier2 Batch A (James Clear, FS Blog)
    - Worker D: Tier2 Batch B (HackerNoon, Scott Young)

If still < 20 items:
  Wave 3 (Browser):
    - Browser Worker: ProductHunt, Latent Space (Require JS rendering)

Phase 3: SubAgent Task Format

Task format received by each SubAgent:

task: fetch_and_extract
sources:
  - id: hn
    url: https://news.ycombinator.com
    extract: top_10
  - id: hf_papers
    url: https://huggingface.co/papers
    extract: top_voted

output_schema:
  items:
    - source_id: string      # Source Identifier
      title: string          # Title
      summary: string        # 2-4 sentence summary
      key_points: string[]   # Max 3 key points
      url: string            # Original URL
      keywords: string[]     # Keywords
      quality_score: 1-5     # Quality Score

constraints:
  filter: "Cutting-edge Tech/Deep Tech/Productivity/Practical Info"
  exclude: "General Science/Marketing Puff/Overly Academic/Job Posts"
  max_items_per_source: 10
  skip_on_error: true

return_format: JSON

Phase 4: Main Agent Monitoring & Feedback

Main Agent Responsibilities:

Monitoring:
  - Check SubAgent return status (success/partial/failed)
  - Count collected items
  - Record success rate per source

Feedback Loop:
  - If a SubAgent fails, decide whether to retry or skip
  - If a source fails per
