weekly

weekly is a command for coding agents from XBlueSky/vatt-ghern. It costs 25 tokens per session (315 once invoked), scanned A, original, MIT.

A command that prepares a weekly summary of the past seven days of posts for the vatt-ghern technology blog and opens a pull request for review.

In plain words
What is it for?
Use it to generate the weekly HTML roundup, run the specified checks, and submit the result to the main branch without merging it.
Why use it?
It avoids manually gathering recent posts and creating the weekly article and review request.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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.

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

weekly 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 5d 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 weekly rollup mode for the vatt-ghern blog.

Use the daily-news skill in this plugin to:

  1. Skip Step 2 (fetch sources), Step 3 (score/filter), Step 4 (pick), Step 5 (deep-story selection), Step 6 (roundup).
  2. Run node ${CLAUDE_PLUGIN_ROOT}/skills/daily-news/scripts/load-past-roundups.mjs --days=7 to gather past 7 days' sidecars.
  3. Read the archetype reference at skills/daily-news/references/archetypes/weekly-rollup.md.
  4. Author exactly ONE src/posts/YYYY/MM/DD/weekly.html (where YYYY-MM-DD is today, a Monday) + matching .11tydata.json.
  5. Run validation (archetype-check, html-validate, link-check). Anti-dedup gate is bypassed by the override_dup_check: true flag in the sidecar.
  6. Open a PR titled weekly: <week range> rollup against main.

Do not merge — the PR waits for human review and Cloudflare Pages preview.

If the past 7 days had fewer than 3 roundups, skip the rollup and report that to the user. 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.
