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 | $0.00094 | $0.01983 |
| Opus 5 | $0.00047 | $0.00992 |
| Sonnet 5 | $0.00019 | $0.00397 |
| Haiku 4.5 | $0.00009 | $0.00198 |
Grade A, and why
domain-strategy 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 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Verify with curl: `curl -I http://example.com`, `curl -I http://www.example.com`, `curl -I https://www.example.com`. All should chain to a single 200 on the canonical. How it starts
The opening of the file, as written. The whole thing — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Domain Strategy
Decide how domains, subdomains, and DNS work across a portfolio. Stack-agnostic. Works for one site or one hundred.
When to use
- Setting up DNS for a new site (apex vs www, primary vs aliases)
- Choosing or switching registrars
- Planning redirects across multiple domains (parked, retired, consolidated)
- Deciding subdomain vs subfolder vs separate domain for a new product line
- Consolidating multiple sites into one
- Splitting one site into multiple
- Setting up DNS for email, security records, third-party services
When NOT to use
- Migrating content between platforms with URL changes (use
content-migration) - Email authentication setup specifically (use
email-deliverability) - Security headers or HTTPS config (use
security-baseline) - Internationalization domain choices (use
internationalization)
Required inputs
- Current domain inventory (every domain you own or operate)
- Status of each (live, parked, redirected, retired)
- Strategic role of each (primary brand, sub-brand, defensive registration, campaign)
- Current DNS provider and registrar for each
- Email and third-party service dependencies
The framework: 5 decisions
Every domain decision falls into one of these buckets. Address them in order.
Decision 1: Apex vs www as canonical
Pick one. Redirect the other to it. Pick before launch. Changing later is painful.
- Apex (example.com): cleaner, more memorable, the modern default.
- www (www.example.com): historically standard, easier to add CDN-level CNAME records (apex CNAME is technically forbidden but most providers offer ALIAS or ANAME).
Whichever you pick, the other must 301 to it. Both serving content is duplicate content and a soft signal of poor setup.
Decision 2: Subdomain vs subfolder vs separate domain
For a new product, blog, or content section:
| Pattern | Use when |
|---|---|
Subfolder (example.com/blog) |
Same brand, want SEO equity to flow, default choice |
Subdomain (blog.example.com) |
Different stack or platform, organizationally separate but related |
Separate domain (exampleblog.com) |
Different brand, different audience, intentional separation |

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.

domain-strategy is a skill published in the GitHub repository rampstackco/claude-skills (830 stars, last pushed yesterday), licensed MIT. It adds 94 tokens to every session and 1,983 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
