A tool for creating and sending a recurring digest about a chosen topic. A digest is a short selection of important updates, gathered from web sources, X, aggregators, and optionally RSS or Atom feeds.

Use it for broad or topic-focused daily updates, such as AI agents, Rust, or Solana. It can use only RSS feeds or combine them with web-based sources.

It cuts a large stream of updates down to a small set of useful findings. It also checks recent digests to avoid repeating information.

Token cost

What it costs to keep this loaded

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	$0.00027	$0.04027
Opus 5	$0.00014	$0.02014
Sonnet 5	$0.00005	$0.00805
Haiku 4.5	$0.00003	$0.00403

Security

Grade A, and why

digest scanned grade A with 1 finding 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

${var} — Selects the digest's topic and which source classes feed it. Grammar:

"" (empty) → digest's default sources (WebSearch + xAI/Grok + aggregators), no topic filter — a broad daily digest.

"<topic>" → topic-focused digest on the default web sources, filtered to <topic> (e.g. "solana", "AI agents", "rust").

"rss" → RSS-only: pull feeds from memory/feeds.yml, no topic filter.

"rss: <topic>" → RSS-only, filtered to <topic> (e.g. "rss: rust").

"<topic> +rss" → default web sources and RSS feeds combined, both filtered to <topic> (e.g. "AI agents +rss").

Today is ${today}. Generate and send a daily ${var} digest.

The whole point of a digest is signal, not volume. A reader skimming for 60 seconds should walk away with three things they didn't know that morning and one of them should change a decision they'd make this week. Anything that doesn't clear that bar gets cut.

Preamble — orient and parse the selector

Read memory/MEMORY.md for high-level context and tracked topics, and scan the last 3 days of memory/logs/ so you can dedup against anything already reported.
Parse ${var} into {topic, sources}:
- Strip a trailing +rss → adds RSS to the default web sources. Remainder is the topic.
- A leading rss: (or the bare token rss) → RSS-only source set; text after the colon is the topic (empty = no filter).
- Otherwise the whole string is the topic and sources = default web (empty string = default web, no topic filter).
- Resulting sources is one of: web (default), rss (RSS-only), or web+rss (both).
The topic, when non-empty, is a filter applied to every source class — web queries are scoped to it and RSS items must match it (title/description/tags). Empty topic = keep all relevant items.

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.

digest is a skill published in the GitHub repository aaronjmars/aeon-agent (11 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 4,027 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to digest, differing in 0 lines, and is treated as a copy.
