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 | $0.00042 | $0.01640 |
| Opus 5 | $0.00021 | $0.00820 |
| Sonnet 5 | $0.00008 | $0.00328 |
| Haiku 4.5 | $0.00004 | $0.00164 |
Grade A, and why
cms-metadata-writer 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CMS Metadata Writer
What This Skill Does
Writes structured metadata fields — title tag, meta description, tags, category, slug, and Open Graph text — for a CMS entry, optimized for search discoverability and social sharing.
When To Use This Skill
- You have a finished article and need to fill in the CMS metadata fields before hitting publish
- You are backfilling metadata for older articles that were published without proper SEO fields
- You need consistent, style-compliant metadata across a batch of articles being migrated to a new CMS
- You want to optimize an existing article's metadata after seeing poor search performance
What You Need To Provide
Required: The article text (or a detailed summary including headline, topic, key facts, and angle); the publication name or site name (for title tag formatting).
Optional: The CMS platform (WordPress, Ghost, Webflow, custom — affects field naming); target keywords or phrases the article should rank for; character limits for title tag and meta description (defaults: 60 characters for title, 155 for description); the publication's tagging taxonomy (list of existing tags to choose from); whether Open Graph / social sharing fields are needed; the article's section or vertical within the publication.
How the Assistant Approaches This
-
Reads the article to identify the core topic, angle, and target audience. The metadata must accurately represent the content — not promise something the article does not deliver. Identifies the primary keyword theme and the article's unique angle within that theme.
-
Writes the title tag for search intent, not just the headline. The article's headline and the SEO title tag serve different purposes. The title tag is rewritten to include the primary keyword naturally, stay within character limits, and communicate what the reader will get — while the headline can be more creative or provocative.
-
Writes the meta description as a click-worthy summary. 150–155 characters that answer the searcher's implicit question: "Is this article worth my time?" Includes the primary keyword, states the article's key value proposition, and ends with a reason to click. No keyword stuffing.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
