Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.00391 |
| Opus 5.5 | $0.00006 | $0.00156 |
| Sonnet 5.5 | $0.00003 | $0.00078 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
rss-digest scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
RSS Digest
Fetches RSS/Atom feeds, filters by keywords, and generates AI-summarized digests.
When to Use
- User wants a daily/weekly digest of their RSS feeds
- Monitoring topics across multiple sources
- Building a curated reading list with summaries
Commands
# Digest from a single feed
bun run rss-digest/scripts/digest.ts --url <feed-url>
# Digest from feeds.json config (incremental — auto-calculates since lastRun)
bun run rss-digest/scripts/digest.ts --feeds feeds.json
# Digest from OPML export
bun run rss-digest/scripts/digest.ts --opml feeds.opml --hours 48
# Raw article list (no AI summary)
bun run rss-digest/scripts/digest.ts --feeds feeds.json --raw
feeds.json Format
{
"feeds": [
"https://example.com/feed",
"https://another.com/rss"
],
"lastRun": "2026-02-18T00:00:00Z",
"keywords": ["education", "AI"],
"noKeywords": ["sponsored", "advertisement"]
}
Requirements
GEMINI_API_KEYenvironment variable- Output goes to
output/digests/by default
Key Feature: Incremental Fetching
When using --feeds, the script reads lastRun from the config and only fetches articles published since then. After running, it updates lastRun automatically. Never manually specify --hours unless overriding.
Output
Markdown digest with executive summary, themed article groups, and "Worth Reading" highlights.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

rss-digest is a skill published in the GitHub repository cdeistopened/skill-stack (30 stars, last pushed 3mo ago), licensed MIT. It adds 16 tokens to every session and 391 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
