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.

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 | $0.00029 | $0.02561 |
| Opus 5.5 | $0.00012 | $0.01024 |
| Sonnet 5.5 | $0.00006 | $0.00512 |
| Haiku 4.5 | $0.00003 | $0.00256 |
Grade A, and why
blog-seo-writing 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 2mo 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.

Blog SEO Writing
When to Activate
- Writing a new blog post targeting a specific keyword or search query
- Optimizing an existing blog post that is underperforming in search
- Building a topic cluster strategy with pillar and cluster pages
- Creating content briefs for writers that include SEO requirements
- Auditing blog content for SEO gaps and opportunities
- Competing for a specific SERP position against known competitors
First Questions
- What is the primary keyword or topic this content should rank for?
- What is the search intent behind this keyword? (What does the searcher actually want?)
- Who are the top-ranking pages for this keyword, and what do they cover?
- What unique angle, data, or expertise can you bring that existing results do not have?
- Is this a pillar page (broad topic) or a cluster page (specific subtopic)?
- What internal pages should this article link to, and which should link to it?
- What is the business goal? (Traffic, leads, conversions, brand awareness?)
Keyword-First Content Planning
Keyword Research Process
- Seed keyword. Start with the broad topic or phrase.
- Expand. Use tools (Ahrefs, SEMrush, Google Search Console, Google autocomplete, "People Also Ask") to find related queries.
- Evaluate. For each keyword, assess:
- Search volume. How many people search for this monthly?
- Keyword difficulty. How hard is it to rank? (Based on competing page authority.)
- Business relevance. Does this keyword attract your target audience?
- Intent match. Can you serve this intent well with a blog post?
- Select primary keyword. One per article. This drives the title, URL, and H1.
- Select secondary keywords. Two to five related terms to include naturally in the content.
Keyword Prioritization Matrix
| Keyword | Volume | Difficulty | Business Relevance | Intent Match | Priority |
|---|---|---|---|---|---|
| [keyword] | [number] | [low/med/high] | [1-5] | [info/nav/comm/trans] | [1-5] |
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.
