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 State/last-check.json

Step 2: Fetch Sources (Parallel)

Launch parallel agents to fetch each source:

Agent	Source	Method
Agent 1	tldrsec.com	WebFetch latest newsletter
Agent 2	no.security	WebFetch recent posts
Agent 3	krebsonsecurity.com	WebFetch recent articles
Agent 4	thehackernews.com	WebFetch headlines
Agent 5	schneier.com	WebFetch recent posts

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

Workflow	Trigger	File
Update	"security updates", "sec updates", "/secupdates", "what's new in security"	Workflows/Update.md

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
