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.

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 | $0.00009 | $0.01038 |
| Opus 5 | $0.00005 | $0.00519 |
| Sonnet 5 | $0.00002 | $0.00208 |
| Haiku 4.5 | $0.00001 | $0.00104 |
Grade A, and why
newsletter-generation 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 13d 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.

Newsletter Generation
Overview
Generates professional, well-researched newsletters combining curated content from multiple sources with original analysis and commentary. Follows modern newsletter best practices (Morning Brew, The Hustle, TLDR, Benedict Evans).
Output is a complete, ready-to-publish newsletter in Markdown.
When to Use
- User asks to generate a newsletter, email digest, or content roundup
- User requests a curated summary of news or developments on a topic
- User wants to create a recurring newsletter format
- User asks to compile recent developments into a briefing
- User asks for a "weekly roundup", "monthly digest", or "morning briefing"
Newsletter Workflow
Phase 1: Planning
Identify:
- Topic(s): main subject(s) of the newsletter
- Format: daily digest, weekly roundup, deep-dive, industry briefing
- Audience: technical, executive, general
- Tone: informative, casual, analytical
- Length: target word count or item count
Phase 2: Research & Curation
Use web_search + browse_page to gather content:
- Search broadly for recent developments on the topic
- Fetch full articles with
browse_pageon promising results - Curate 5-10 items worth featuring — prioritize:
- Breaking news / announcements
- Original analysis / thought leadership
- Data releases / reports
- Interesting perspectives
- Extract key facts from each source: headline, key point, why it matters
- Verify claims with a second source where possible
Phase 3: Writing
Structure the newsletter:
# [Newsletter Name] — [Date]
## This Week's Headline
[1-2 sentence hook for the top story]
---
## Top Stories
### 1. [Headline]
[2-3 sentence summary of the story]
**Why it matters**: [1 sentence on significance]
[Source](URL)
### 2. [Headline]
[...]
### 3. [Headline]
[...]
---
## Quick Hits
- [Brief item with link](URL)
- [Brief item with link](URL)
- [Brief item with link](URL)
---
## Deep Dive: [Topic]
[Longer analysis section on one key topic — 200-400 words.
Original commentary, not just summary. Add your perspective on
what this means for the audience.]

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.
