seo-drift

seo-drift is a skill for Claude Code from AgriciDaniel/seo-os. It costs 86 tokens per session (1,709 once invoked), scanned A, original, AGPL-3.0.

A monitoring tool that records important SEO page elements and compares them over time. It works like a change history for search-related page content and settings.

In plain words
What is it for?
Use it to create a baseline, compare before-and-after versions, investigate whether an SEO change caused a problem, and track page changes.
Why use it?
Website updates can accidentally remove or alter titles, metadata, structured data, or other search details. Comparing snapshots helps reveal those regressions.

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

seo-drift 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 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

Changes

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.
