blogwatcher

A tool for watching RSS and Atom feeds, which are web formats that publish updates from blogs and other sites. It fetches, reads, and summarizes new posts.

In plain words
What is it for?
Use it to monitor feeds, find new blog posts, and summarize the latest entries.
Why use it?
It avoids checking multiple blogs manually for updates. It gives you a way to track new content from feed URLs in one workflow.

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.

Security

Grade A, and why

blogwatcher 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

Adversarial review of freshly-built code — find what was missed, what's inconsistent, what breaks. The single code reviewer for the loop, and it runs exactly once per session.
