+# RSS-to-Twitter Agent (Playwright)
+
+This template keeps the original behavior:
+
+1. Fetch RSS news
+2. Summarize with Ollama
+3. Ask you `y/n/q` per thread
+4. If `y`, auto-open Twitter/X and post via Playwright
+
+Updated for Hive v0.6+ project layout and credential namespace support.
+
+## Run
+
+From repo root:
+
+```bash
+cd /Users/vasu/Desktop/hive
+uv run python -m examples.templates.rss_twitter_agent run \
+  --feed-url "https://news.ycombinator.com/rss" \
+  --max-articles 3
+```
+
+Optional credential ref (v0.6 format):
+
+```bash
+uv run python -m examples.templates.rss_twitter_agent run \
+  --feed-url "https://news.ycombinator.com/rss" \
+  --max-articles 3 \
+  --twitter-credential-ref twitter/default
+```
+
+## Validate / Info
+
+```bash
+uv run python -m examples.templates.rss_twitter_agent validate
+uv run python -m examples.templates.rss_twitter_agent info
+```
+
+## Ollama prerequisites
+
+```bash
+ollama serve
+ollama pull llama3.2
+```
+
+## Behavior notes
+
+- First posting run opens browser login and stores session.
+- Later runs reuse session automatically.
+- You can override session path with `HIVE_TWITTER_SESSION_DIR`.
+- Credential reference uses `{name}/{alias}` (example: `twitter/default`).
+- Interactive review still uses per-thread `y/n/q` approval before posting.
