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.

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 | $0.00043 | $0.03800 |
| Opus 5.5 | $0.00017 | $0.01520 |
| Sonnet 5.5 | $0.00009 | $0.00760 |
| Haiku 4.5 | $0.00004 | $0.00380 |
Grade A, and why
sf-migration-checklist 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 2mo 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 — 420 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SF Migration Checklist – Technical SEO
Orchestration skill for site migrations. Guides the agent through classification, planning, execution, and validation, with quality gates at every critical phase.
Language mode
- Default to Italian if the user writes in Italian.
- Default to English if the user writes in English.
- If the target market is specified, adapt terminology to that market.
- Preserve the same quality controls in both languages.
How this skill works
This skill is an orchestrator: it defines the workflow, decision points, and
required outputs. Detailed operational checklists live in references/ and are
loaded only when relevant based on migration classification.
Reference files:
references/pre-migration-checklist.md— detailed checks for Steps 1–2references/technical-validation.md— detailed checks for Steps 3–4references/post-migration-monitoring.md— detailed checks for Steps 5–7references/anti-patterns.md— known mistakes with examplesreferences/conditional-modules.md— modules for international, multi-domain, infra, phased migrations
Intended use
- Technical SEO audits before, during, and after migration
- Platform, domain, or infrastructure migrations
- Complex or high-risk site changes
- Migration success evaluation and post-mortem
The skill prioritizes technical correctness and signal preservation over speed of release or aesthetic considerations.
Step 0 – Migration Classification (Mandatory)
Do not proceed until the migration has been correctly classified. Incorrect classification leads to unnecessary checks or missing critical risks.
0.1 Identify migration type(s)
Classify the migration into one or more categories:
| # | Type | URL change | Domain change | Redirect planning |
|---|---|---|---|---|
| 1 | Domain migration (rebranding only) | No | Yes | Yes |
| 2 | Platform + URL structure (same domain) | Yes | No | Yes |
| 3 | Platform + URL structure + domain | Yes | Yes | Yes |
| 4 | Platform only (no URL/domain change) | No | No | Minimal |
| 5 | Multi-domain → single-domain consolidation | Yes | Yes | Yes |
| 6 | Section migration to separate domain | Partial | Yes | Yes |
| 7 | Infrastructure or protocol migration | No | No | Conditional |
| 8 | International SEO migration | Varies | Varies | Yes |
| 9 | Partial or phased migration | Varies | Varies | Yes |
What ships with it
5 files 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.
