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 | $0.00046 | $0.00526 |
| Opus 5 | $0.00023 | $0.00263 |
| Sonnet 5 | $0.00009 | $0.00105 |
| Haiku 4.5 | $0.00005 | $0.00053 |
Grade A, and why
seo-ahrefs 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.
What it actually says
seo-ahrefs
Live Ahrefs data via the official @ahrefs/mcp server.
Prerequisites
- Run
extensions/ahrefs/install.sh(Linux/macOS) orinstall.ps1(Windows) before using this skill. - An Ahrefs API token (https://ahrefs.com/api).
- Node 18+ on
$PATHfor the MCP server.
Before calling any Ahrefs tool, verify the MCP is connected by checking that any Ahrefs MCP tool is available in this session. If tools are not available, tell the user the extension is not installed and provide the install command above.
Routing
| Command | Action |
|---|---|
/seo ahrefs metrics <url> |
Domain / URL rating, referring domain count, organic traffic estimate |
/seo ahrefs backlinks <url> |
Top referring domains, anchor distribution, follow/nofollow ratio |
/seo ahrefs organic <url> |
Organic keywords, ranking distribution, traffic by country |
/seo ahrefs content <topic> |
Content Explorer top results, social shares, referring domains |
Output conventions
- Cite the data source on every metric: "Ahrefs (live, confidence 1.00)".
- When Ahrefs and Moz disagree on the same metric, trust Ahrefs and note the discrepancy in the report.
- Toxic link assessment: combine Ahrefs Spam Score with the existing seo-backlinks Common Crawl + verify crawler signals.
Cross-skill delegation
- For multi-source confidence weighting across Moz + Bing + Common Crawl + Ahrefs, hand back to
seo-backlinks. - For SERP-feature analysis where Ahrefs and DataForSEO overlap, prefer DataForSEO for live SERP data.
Cost guardrails
Ahrefs API usage is metered per unit. Before running a batch (>= 50 URLs):
- Estimate cost with
python scripts/dataforseo_costs.py(the cost-tracker module is generic and supports Ahrefs unit accounting). - Surface the estimate to the orchestrator.
- Log actual cost after each call.
This is the same workflow the seo-dataforseo skill uses.
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.

seo-ahrefs is a skill published in the GitHub repository Infrasity-Labs/dev-gtm-claude-skills (124 stars, last pushed 2mo ago), licensed MIT. It adds 46 tokens to every session and 526 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
