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 | $0.00076 | $0.02502 |
| Opus 5 | $0.00038 | $0.01251 |
| Sonnet 5 | $0.00015 | $0.00500 |
| Haiku 4.5 | $0.00008 | $0.00250 |
Grade A, and why
seo-rank-tracker 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.

seo-rank-tracker — Keyword Ranking Monitoring
Ranking Data Sources
Primary Sources
| Source | Data Type | Pros | Cons |
|---|---|---|---|
| GSC Search Performance | Avg position (impressions-weighted) | Free, real data, query-level | Averaged, 2-day delay, sampled |
| CrUX + GSC combined | Position + performance correlation | Links CWV to rankings | Requires both APIs |
| Third-party SERP APIs | Exact position, SERP features | Real-time, geo-specific | Paid, rate-limited |
| Manual spot checks | Visual SERP inspection | Accurate, sees full context | Doesn't scale |
GSC Position Data Caveats
- Position is impressions-weighted average — a page ranking #3 for 100 impressions and #50 for 10 impressions shows as ~7.3
- Data is 2 days delayed (hourly granularity available via API since Dec 2025)
- Positions are sampled for high-volume queries
- Filter by
deviceto see mobile vs desktop separately - Filter by
countryfor geo-specific rankings
SERP Feature Tracking (2026)
Features to Monitor
| Feature | Prevalence | Impact on Organic CTR |
|---|---|---|
| AI Overviews | 48% of queries | -34 to -46% CTR for positions below |
| Featured Snippets | ~12% of queries | +2x CTR if captured (Position 0) |
| People Also Ask (PAA) | ~65% of queries | Moderate — clicks distributed |
| Video Carousel | ~20% of queries | High for how-to/tutorial content |
| Image Pack | ~30% of queries | Moderate — drives image search traffic |
| Local Pack | ~35% of local queries | Very high — dominates local intent |
| Knowledge Panel | ~20% of brand queries | Builds trust, reduces clicks to site |
| Shopping Results | ~25% of product queries | High for e-commerce |
| AI Mode (Zero Links) | Growing (180+ countries) | 100% — no organic results shown |
AI Overview Impact Analysis
When AI Overviews appear for your target queries:
- Cited in AIO: Position preserved, CTR may increase (trusted source signal)
- Not cited in AIO: CTR drops 34-46% even if ranking #1
- Strategy: Optimize for citation (see
seo-geoskill) rather than just ranking
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.
