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 7d 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.

Docker with persistent storage

By default the database lives at ~/.blogwatcher-cli/blogwatcher-cli.db. In Docker this is lost on container restart. Use BLOGWATCHER_DB or a volume mount to persist it:

# Named volume (simplest)
docker run --rm -v blogwatcher-cli:/data -e BLOGWATCHER_DB=/data/blogwatcher-cli.db ghcr.io/julientant/blogwatcher-cli scan

# Host bind mount
docker run --rm -v /path/on/host:/data -e BLOGWATCHER_DB=/data/blogwatcher-cli.db ghcr.io/julientant/blogwatcher-cli scan

Migrating from the original blogwatcher

If upgrading from Hyaxia/blogwatcher, move your database:

mv ~/.blogwatcher/blogwatcher.db ~/.blogwatcher-cli/blogwatcher-cli.db

The binary name changed from blogwatcher to blogwatcher-cli.

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.
