Category Definitions

🔴 Security News (Breaches & Incidents)

• Data breaches and leaks
• Active exploits and attacks
• Ransomware incidents
• State-sponsored attacks
• Major vulnerability exploitations
• Company security incidents

• Security research papers
• New attack techniques
• Tool releases
• Vulnerability disclosures
• Bug bounty findings

💡 Security Ideas

• Industry trends and analysis
• Security strategy and opinions
• Career and hiring trends
• Regulatory and compliance news

• Predictions and forecasts

Ranking Criteria

Within each category, rank items by:

1. Impact - How many people/systems affected?
2. Recency - How new is this?
3. Actionability - Can reader do something about it?
4. Novelty - Is this genuinely new information?

State Tracking

State file: State/last-check.json

{
  "last_check_timestamp": "2026-01-22T12:00:00.000Z",
  "sources": {
    "tldrsec": {
      "last_hash": "abc123",
      "last_checked": "2026-01-22T12:00:00.000Z",
      "last_title": "tl;dr sec #XXX"
    },
    "nosecurity": {
      "last_hash": "def456",
      "last_checked": "2026-01-22T12:00:00.000Z"
    }
  }
}

On each run:

1. Load last-check.json
2. Fetch each source
3. Compare content hash to detect new items
4. Only include items newer than last check
5. Update state file after successful run

Process Flow

Step 1: Check State

# Read last check timestamp
cat ~/.opencode/skills/SECUpdates/State/last-check.json

Step 2: Fetch Sources (Parallel)

Launch parallel agents to fetch each source:

Step 3: Parse & Categorize

For each item found:

1. Determine category (News/Research/Ideas)
2. Extract headline and 1-2 sentence summary
3. Note source
4. Assess importance score

Step 4: Rank & Limit

1. Sort each category by importance
2. Take top items until 32 total
3. Distribute reasonably (aim for ~10-12 per category if available)

Step 5: Output & Update State

1. Generate formatted output
2. Write updated state to last-check.json

Workflow Routing

Default: Run the Update workflow.

Key Principles

1. Crisp - 1-2 sentences per item, no fluff
2. Ranked - Most important first within each category
3. Categorized - Clear separation of News/Research/Ideas
4. Deduplicated - Same story from multiple sources = one entry
5. Limited - Max 32 items total, quality over quantity
6. Stateful - Track what's been seen, only show new items
