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 | $0.00080 | $0.03295 |
| Opus 5 | $0.00040 | $0.01648 |
| Sonnet 5 | $0.00016 | $0.00659 |
| Haiku 4.5 | $0.00008 | $0.00330 |
Grade A, and why
dfs-onpage-api 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 9d 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.

DataForSEO OnPage API
Comprehensive on-page SEO analysis with support for instant single-page checks and full website crawls.
Overview
This skill provides access to the DataForSEO OnPage API for technical SEO analysis. It supports two primary workflows:
- Instant Analysis - Quick single-page analysis without task creation (ideal for spot checks)
- Full Site Crawls - Comprehensive website audits with task-based crawling (ideal for complete technical audits)
Quick Decision Guide
Use instant_pages.py when:
- Analyzing a single page quickly
- Need immediate results without waiting for crawl
- Checking page performance, Core Web Vitals, or specific technical issues
- No task management needed
Use task_post.py + retrieval scripts when:
- Auditing an entire website
- Need bulk data for multiple pages
- Want to identify site-wide issues (duplicates, broken links, redirect chains)
- Require comprehensive technical SEO audit
Instant Single-Page Analysis
instant_pages.py
Performs real-time analysis of individual web pages without task creation. Returns immediate results.
Basic usage:
python scripts/instant_pages.py --url https://example.com/page
With Core Web Vitals (browser rendering):
python scripts/instant_pages.py \
--url https://example.com/page \
--enable-browser-rendering \
--load-resources
With custom output path:
python scripts/instant_pages.py \
--url https://example.com/page \
--enable-browser-rendering \
--output output/onpage_instant_example.json
Key Parameters:
--url(required): Target page URL--enable-browser-rendering: Measure Core Web Vitals (CLS, LCP, FID)--enable-javascript: Execute page JavaScript--load-resources: Load images, scripts, stylesheets--store-raw-html: Save HTML for later analysis--check-spell: Enable spelling verification--browser-preset: Device type (desktop, mobile, tablet)--output: Custom output path

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.

dfs-onpage-api is a skill published in the GitHub repository Buzzmatic/awesome-agent-skills (1 stars, last pushed 2mo ago), licensed MIT.
