Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00023 | $0.00305 |
| Opus 5 | $0.00012 | $0.00152 |
| Sonnet 5 | $0.00005 | $0.00061 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
monthly 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 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.
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.
What it actually says
Execute the daily-news skill in monthly rollup mode for the vatt-ghern blog.
Use the daily-news skill in this plugin to:
- Skip Step 2 (fetch sources) through Step 6 (roundup).
- Determine the calendar-month length (28-31 days) of the month that just ended.
- Run
node ${CLAUDE_PLUGIN_ROOT}/skills/daily-news/scripts/load-past-roundups.mjs --days=<N> --end=<last day of last month>to gather the past month's sidecars. - Read the archetype reference at
skills/daily-news/references/archetypes/monthly-rollup.md. - Author exactly ONE
src/posts/YYYY/MM/01/monthly.html(where YYYY-MM-01 is the first day of the new month) + matching.11tydata.jsonwithoverride_dup_check: true. - Run validation (
archetype-check,html-validate,link-check). - Open a PR titled
monthly: <YYYY-MM> rollupagainstmain.
Do not merge — the PR waits for human review and Cloudflare Pages preview.
If the prior month had fewer than 8 roundups, skip the rollup and report that. No PR.
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.
