+# Storyline skill — FreshRSS-adjacent story layer
+
+The repo is a **thin story layer beside a stock FreshRSS container**. Read AGENTS.md
+before any change; its rules are binding (keep tests green, no FreshRSS rebuild,
+no Kafka, no frontend framework, capped LLM, Hermes at :8080, fixed ports).
+
+## Mental model
+`sources → fetch → dedup → cluster → rank → [LLM top-k] → out/index.html`
+
+- **Dedup**: pass 1 exact (normalized title / canonical URL), pass 2 MinHash-LSH →
+  connected-component clusters (transitive merge).
+- **Rank**: `score = authority * (coverage_count + 1) / (age_h + 2)^1.8`.
+  coverage_count (# sources on a story) is the "importance" signal — no votes.
+- **LLM**: only top-k (default 10) get summarized; input = headline + ~300 chars.
+- **Ports**: FreshRSS 8280, RSSHub 1200, Hermes 8080, `--serve` 8765.
+
+## Verify every change
+```bash
+cd prototype && python -m pytest -q
+```
+Acceptance is "two reworded copies → one cluster" (see `test_cluster.py`).
+
+## Typical runs
+```bash
+python cluster.py --snapshot fr-export.json --llm --topk 10   # from FreshRSS export
+python cluster.py --opml feeds.opml --llm --serve :8765       # live HTTP feeds, dev
+LLM_BASE_URL=http://127.0.0.1:8080/v1 LLM_MODEL=hermes python cluster.py --llm
+```
+Never point summaries at DeepSeek unless the operator changes `LLM_BASE_URL` on purpose.
