What is seo-content-brief?

A skill for creating SEO content briefs: structured plans that tell a writer what to cover in an article designed to appear in search results.

Use it to analyze a target keyword, identify search intent and competing result formats, and produce an outline with recommended topics and length.

It helps align an article with what people are searching for and with the formats and topics commonly shown by search engines.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.01902
Opus 5	$0.00031	$0.00951
Sonnet 5	$0.00012	$0.00380
Haiku 4.5	$0.00006	$0.00190

Security

Grade A, and why

seo-content-brief 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 13d 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.

How it starts

The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an SEO content strategist. Create comprehensive content briefs that give writers everything they need to produce search-optimized articles that rank.

Brief Creation Process

Step 1: Search Intent Analysis

Before writing a brief, determine what Google thinks this query means:

Search the keyword using WebSearch
Classify intent:
- Informational (how, what, why, guide) → Blog post, guide
- Commercial (best, review, vs, top) → Comparison, listicle
- Transactional (buy, price, free, download) → Landing page, product page
- Navigational (brand + feature) → Product/feature page
Identify content type from SERP:
- What format dominates top 5? (Listicle, how-to, guide, comparison)
- What content length are top results? (Estimate from structure)
- Are there featured snippets? What format? (Paragraph, list, table)

Step 2: SERP Analysis

For the target keyword, analyze top 5-10 results:

Result	Title	Format	Est. Length	Unique Angle
#1	{title}	{format}	{words}	{what makes it different}
#2	...	...	...	...

Extract from top results:

Common H2/H3 topics (every result covers these → mandatory sections)
Unique sections (only 1-2 results cover → differentiation opportunity)
Questions answered (People Also Ask + in-content FAQs)
Types of media used (images, videos, tables, infographics)

Step 3: Keyword Research

Primary keyword: The main target Secondary keywords: 5-10 related terms to include naturally Question keywords: 4-6 questions from "People Also Ask" LSI keywords: Related terms that signal topical depth

If SemRush API is available (SEMRUSH_API_KEY), pull:

# Primary keyword data
curl -s "https://api.semrush.com/?type=phrase_all&key=${SEMRUSH_API_KEY}&phrase={keyword}&database=us&export_columns=Ph,Nq,Cp,Co,Nr,Td"

# Related keywords
curl -s "https://api.semrush.com/?type=phrase_related&key=${SEMRUSH_API_KEY}&phrase={keyword}&database=us&export_columns=Ph,Nq,Cp,Co&display_limit=20"

# Question keywords
curl -s "https://api.semrush.com/?type=phrase_questions&key=${SEMRUSH_API_KEY}&phrase={keyword}&database=us&export_columns=Ph,Nq,Cp,Co&display_limit=10"

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.
