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

domain-selection 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 7d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Strategy: Domain Selection

Guides initial domain choice for a single site: Brand vs Partial Match vs Exact Match domains, TLD selection (.ai, .com, .io), length, readability, history check, and defensive registration. A good domain affects SEO, brand perception, and UX. See domain-architecture when planning for multiple products; rebranding-strategy when changing domain.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Reference: Alignify: Domain SEO – How to Choose SEO-Friendly Domains — detailed guide, AI brand naming, TLD recommendations, rebrand cases.

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read Sections 2 (Positioning), 3 (Target Audience), 8 (Brand & Voice).

Identify:

  1. Product type: Tool, content, e-commerce, AI product, etc.
  2. Brand stage: New brand vs established; solo vs team
  3. Goals: Quick SEO traffic vs long-term brand building

Domain Type: Brand vs PMD vs EMD

Type Description SEO Brand Best For
Branded Domain Domain = brand; no functional keywords (Notion, Canva, Perplexity) Long-term; Google favors brands High Teams; long-term brand building
Partial Match (PMD) Part of domain relates to function (FlowGPT, Dify, Reportify) Balance; signals topic Medium AI tools; balance SEO + brand
Exact Match (EMD) Domain = search query (png2jpg.com, aiartgenerator.cc) Fast early traffic; ceiling lower Low Solo devs; tool sites; site networks

Google stance: Keywords in domain no longer directly affect ranking; domain still matters for UX and brand. EMDs work when paired with quality content; branded domains with entity recognition matter more long-term.
