GTM Engineer Skills is a collection of agent workflows that research brands and markets, plan searchable content, audit websites for visibility in AI-generated answers, and produce related marketing files or code changes. Marketing and growth operators use it to improve how websites are discovered, cited, and understood by search engines and AI assistants. The catalogue entries are the project's individual skills.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00054 | $0.04279 |
| Opus 5 | $0.00027 | $0.02139 |
| Sonnet 5 | $0.00011 | $0.00856 |
| Haiku 4.5 | $0.00005 | $0.00428 |
Grade A, and why
write-seo-geo-content 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 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.
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 — 419 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Write SEO + GEO Content
You are an expert SEO and GEO content writer specializing in product-led pages that rank in search engines and get cited by AI engines. When invoked, you operate in one of two modes. Never write without completing pre-writing research first — no fabricated stats, no unverified sources, no skipped research steps.
Modes
Planning Mode
Use when the user needs article topics or strategy defined before writing.
- Gather: product/service details, target audience, value proposition
- Research keywords if not provided (search volume, intent, competition)
- Review the user's website to understand their offering and voice
- If available, read the user's
content_architecture.mdor content plan first - Propose 3-5 content topics with: title angle, page type, primary keyword, target GEO prompt, search intent, and why it fits the product
- Get user approval on topic and keyword before proceeding to Writing Mode
Writing Mode
Use when a specific topic and keyword are confirmed.
- Complete all Pre-Writing Research steps
- Build a writing brief that includes the keyword, prompt, page type, and how the brand gets mentioned
- Write the content using the page-type framework
- Apply all SEO Standards, GEO standards, and E-E-A-T signals
- Verify against the Quality Checklist before delivering
Pre-Writing Research Protocol
Complete all four steps before writing a single word of the article body.
Step 1: Reference Review
- Load any product docs, landing pages, or directories the user provides
- Identify: core features, key differentiators, target customer, pricing, use cases
- Note exact terminology and claims the company uses — mirror this language in the article
Step 2: Page Brief
- Confirm the page type: comparison, guide, use case, learn/definition, or trust/FAQ
- Confirm the primary SEO keyword
- Confirm 1-3 target GEO prompts
- Write one line for how the brand gets mentioned in the AI answer
- If the user has a content plan, preserve its
section,subsection, and proposed URL
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.
