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 C, and why

seo-ahrefs-keywords scanned grade C with 2 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Verify with: cat ~/.claude/mcp.json | grep -i ahrefs

Reads MCP configurationmediumAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

Ahrefs Organic Keywords

Fetches top organic keywords a domain ranks for, sorted by estimated traffic (highest-value keywords first).

References

@skills/seo/references/mcp-degradation.md @skills/seo/references/ahrefs-api-reference.md

Inputs

  • domain: The bare domain to analyze (e.g., example.com). Strip https://, http://, and trailing slashes before passing to Ahrefs tools.

MCP Check

Before proceeding, verify Ahrefs MCP is available:

  1. Use ToolSearch with query +ahrefs
  2. If tools are returned → Ahrefs MCP is available, proceed to Execution
  3. If no tools returned → display the Ahrefs MCP error template from references/mcp-degradation.md and stop

Execution

Step 1 — Call Organic Keywords

Call mcp__claude_ai_ahrefs__site-explorer-organic-keywords with:

  • target: the bare domain (e.g., example.com)

Returns per keyword: keyword, position, volume, cpc (CENTS), traffic, traffic_percent

Step 2 — CRITICAL: Monetary Conversion

cpc is returned in CENTS. Divide by 100 before display. Format as USD per click: $X.XX.

Example: API returns cpc = 250 → display as $2.50/click

Step 3 — Sort and Cluster

  • Sort by traffic descending (highest-value keywords first)
  • Identify top 3 keyword clusters by topic (group keywords sharing root terms or intent — e.g., "seo tools", "seo software", "best seo tool" form one cluster)

Output Format

## Ahrefs Organic Keywords: example.com

### Top Keywords (by Traffic)

| Keyword | Position | Search Volume | CPC | Est. Traffic | Traffic % |
|---------|----------|--------------|-----|-------------|-----------|
| seo tools | #3 | 22,000 | $4.50/click | 3,200 | 12.4% |
| best seo software | #5 | 8,100 | $6.20/click | 890 | 3.5% |
| keyword research tool | #8 | 5,400 | $3.10/click | 410 | 1.6% |

### Summary
- **Total organic keywords:** 12,450
- **Total estimated traffic:** 25,700 visits/mo

### Top Keyword Clusters
1. **SEO tools** — "seo tools", "best seo software", "seo tool comparison" (combined traffic: 4,500)
2. **Keyword research** — "keyword research tool", "find keywords", "keyword tracker" (combined traffic: 1,800)
3. **Backlink analysis** — "backlink checker", "check backlinks", "link analysis tool" (combined traffic: 1,200)

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.
