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 | $0.00136 | $0.02195 |
| Opus 5 | $0.00068 | $0.01097 |
| Sonnet 5 | $0.00027 | $0.00439 |
| Haiku 4.5 | $0.00014 | $0.00219 |
Grade A, and why
ai-daily-brief 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Daily Brief
You produce a daily AI news digest from RSS feeds — something a busy person can scan in 5 minutes over coffee and know what matters.
Why this matters
There are dozens of great AI newsletters and blogs, but nobody has time to check them all. This skill pulls from the user's curated list of feeds, filters to what's recent, and presents it in a single page with the most interesting stuff front and center.
Input
The user provides:
- Topic preferences (optional) — what they care about most, what's highlight-worthy. Examples: "LLM reasoning", "open source models", "AI regulation", "practical ML engineering". If not provided, use general AI/ML relevance as the filter.
- Feed list (optional) — custom RSS/Atom feed URLs. If not provided, use the defaults in
assets/feeds.json. - Date range (optional) — defaults to today + last 7 days.
Feed Configuration
Default feeds
Read assets/feeds.json in this skill's directory for the default feed list. The file structure is:
{
"feeds": [
{
"name": "Display Name",
"url": "https://example.com/feed",
"category": "Category Label"
}
]
}
User-provided feeds
Users can:
- Pass additional feed URLs directly in their prompt ("also include https://example.com/feed")
- Provide a custom
feeds.jsonfile that overrides or extends the defaults - Ask to add/remove feeds from the default list for future runs
When the user provides extra feeds, merge them with the defaults (don't replace unless explicitly asked).
How to fetch and parse feeds
IMPORTANT: Always use feedparser as the primary method. Write a single Python script that fetches all feeds, parses articles, cleans summaries, filters by date, and writes the results to a JSON file. Then use that JSON to build the HTML output. Only fall back to web search if feedparser fails for a specific feed (e.g., network issues, blocked domains) — and even then, note the fallback in the output.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ai-daily-brief is a skill published in the GitHub repository ajayrenganathan/ai-skills (2 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 136 tokens to every session and 2,195 once invoked, about $0.0007 per session on Opus 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 2026-08-31.
