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 | $0.00096 | $0.03592 |
| Opus 5 | $0.00048 | $0.01796 |
| Sonnet 5 | $0.00019 | $0.00718 |
| Haiku 4.5 | $0.00010 | $0.00359 |
Grade A, and why
seo-drift 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 12d 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.
This is a copy
89% identical to seo-drift — 26 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Example output: examples/seo-drift-wix-com-20260514/compare/DRIFT-REPORT.md
SEO Drift
Git for SEO. Capture a snapshot of a domain or URL's SEO state ("baseline"), then on later runs diff the current state against the baseline and surface regressions. Catches the things that get worse silently after a deploy, redesign, or content cull.
Acknowledgements: drift-as-an-SEO-skill framework originated in
claude-seoby AgriciDaniel (with the original concept credited to Dan Colta, Pro Hub Challenge). MIT-licensed both directions; this implementation is independent but the framing is theirs.
Prerequisites
- DataForSEO MCP server connected.
- Claude's
WebFetchtool available (for URL-mode page fingerprinting). - User provides: target domain or URL, plus a subcommand (
baseline,compare,history).
Optional flags
| Flag | Mode | Effect |
|---|---|---|
--no-firecrawl |
baseline, compare | Skip Firecrawl-based <head> + JSON-LD capture even when Firecrawl is installed (saves credits at the cost of canonical / robots / og:* / JSON-LD diff coverage). |
--skip-cwv |
baseline, compare | Skip the Google CrUX capture (step 4b) even when google-api.json is configured. Useful when you only care about content/structural drift, or when CrUX rate-limit concerns outweigh CWV coverage. Mirrors theirs at seo-drift/SKILL.md:107, 131. |
--baseline-id <n> |
compare | Compare against a specific baseline by ID rather than the most recent. |
--limit <n> |
history | Cap the number of historical entries shown. |
Subcommands
baseline <target>
Capture the current SEO state and write it to a snapshot file. No diff produced.
compare <target>
Load the most recent baseline for the target. Capture the current state. Diff. Produce DRIFT-REPORT.md.
history <target>
List all stored baselines for the target with their dates and key metrics (DA, traffic, keyword count). No diff produced.
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.
