Filtering

# Filter by relative time (past hours/days/minutes)
agent-rss fetch --all --since 1h      # past 1 hour
agent-rss fetch --all --since 2d      # past 2 days
agent-rss fetch --all --since 30m     # past 30 minutes

# Filter by absolute time
agent-rss fetch --all --since 2026-03-12
agent-rss fetch --all --since 2026-03-12T08:00:00+08:00 --until 2026-03-12T18:00:00+08:00

agent-rss fetch --all --title "AI"

# Filter by content keyword
agent-rss fetch --all --content "machine learning"

# Combine filters
agent-rss fetch --all --since 1d --title "Go" --title "Rust"

Global Options

# Use a custom feeds file

Best Practices for AI Agents

Many AI agent environments (like Claude Code, OpenClaw, etc.) have output size limits for bash commands. When fetching RSS feeds with lots of content, the output may be truncated.

Recommended approach: Write output to a file, then use the agent's file reading capability to access the full content.

# Write RSS output to a temporary file
agent-rss fetch --all --since 2026-03-12 > /tmp/rss-output.json

# Then use the agent's Read tool to access the complete content
# The agent can read /tmp/rss-output.json without size limitations

This pattern ensures:

• No truncation of RSS content
• Full access to all fetched items
• Better handling of large feeds

Feeds File Format

Feeds are stored in ~/.config/agent-rss/feeds.txt:

# Comments start with #
hn https://news.ycombinator.com/rss
golang https://blog.golang.org/feed.atom

Output Format

NDJSON (default)

{"name":"hn","src":"https://...","time":"2026-03-12T15:30:00+08:00","title":"...","content":"...","link":"...","id":"..."}
{"name":"hn","src":"https://...","time":"2026-03-12T14:20:00+08:00","title":"...","content":"...","link":"...","id":"..."}

JSON

[
  {"name":"hn","src":"https://...","time":"2026-03-12T15:30:00+08:00","title":"...","content":"...","link":"...","id":"..."},
