seo-monitor

seo-monitor is a skill for Claude Code, Codex from jgoullet/seo-geo-audit. It costs 155 tokens per session (3,784 once invoked), scanned A, original, MIT.

An SEO monitoring workflow that rechecks a previously audited website and compares its current state with the original baseline. It produces a report of improvements, regressions, and alerts.

In plain words
What is it for?
Use it to check whether SEO fixes worked, track changes over time, identify regressions, and generate dated delta reports and alerts.
Why use it?
A one-time audit cannot show whether later changes helped or harmed the site. Baseline comparisons reveal what changed and what still needs attention.

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-monitor 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.

Skill: SEO Monitor — Periodic Delta Tracking

All responses and reports are produced in English by default. Switch to the user's language if they explicitly request it.


Overview

This skill is Step 4 in the SEO-GEO pipeline. It re-crawls a previously audited site, compares the current state against the original baseline, and produces a delta report highlighting what improved, what regressed, and what needs attention.

Position in the pipeline

                       ↓                                │

                       ↓
              ↻ loops back to collector for next cycle

What it produces

seo-project-[domain]/
└── monitoring/
    ├── baseline.json           ← Snapshot from the first audit (created once)
    ├── scan-[date].json        ← Each new crawl result
    ├── delta-[date].md         ← Comparison report (human-readable)
    ├── delta-[date].json       ← Comparison data (machine-readable)
    ├── alerts.md               ← Active alerts (updated each scan)
    └── history.md              ← Score evolution over time

Step 0: Determine monitoring mode

First run (no baseline exists)

If no monitoring/baseline.json exists in the project folder:

  1. Check if site-data.json and audit-actions.json exist from a previous audit
  2. If yes → convert them into the baseline:
    • Copy site-data.jsonmonitoring/baseline.json (add baseline_date field)
    • Extract scores from audit-actions.json → store in baseline
  3. If no → ask the user:
    No previous audit found for this domain.
    Would you like me to:
      1. Run a full audit first (collector + audit) to establish the baseline
      2. Run a quick scan now and use it as the baseline

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.
