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 | $0.00099 | $0.01085 |
| Opus 5 | $0.00049 | $0.00543 |
| Sonnet 5 | $0.00020 | $0.00217 |
| Haiku 4.5 | $0.00010 | $0.00109 |
Grade A, and why
domain-architecture 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 9d 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.

Strategy: Domain Architecture
Guides domain structure decisions for multiple products or brands: subfolder (subdirectory), subdomain, or independent domain. Covers brand architecture (Branded House vs House of Brands) and Hub-Spoke principles when multiple domains coexist. See domain-selection for initial domain choice (Brand/PMD/EMD, TLD); website-structure for single-domain page planning; rebranding-strategy for domain change and migration; multi-domain-brand-seo for brand search optimization.
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.
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for product portfolio and growth goals.
Identify:
- Product count: Single product vs multiple products/brands
- Brand strategy: Unified brand vs distinct brands
- Current state: Planning from scratch vs consolidating existing domains
- Constraints: Tech stack, team, budget
Domain Structure Options
| Structure | Example | SEO Authority | Brand Independence | Typical Use |
|---|---|---|---|---|
| Subfolder | company.com/product-a | Shared with main domain | Low | Products under one brand; SMB; content consolidation |
| Subdomain | product.company.com | Treated separately by Google | Medium | Separate product experience; tech isolation; support/docs |
| Independent domain | product.ai | None shared | High | Acquired brands; different markets; distinct brand identity |
When to Use Each
| Choose | When |
|---|---|
| Subfolder | Products share value proposition; want to strengthen main domain; SMB; blog, tools, features under one brand |
| Subdomain | Need separate tech stack (e.g., app vs marketing); support portal; docs; distinct UX but same brand |
| Independent domain | House of Brands; acquired company; different audience; different TLD (e.g., .ai for AI product) |
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.
