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 | $0.00137 | $0.01380 |
| Opus 5 | $0.00068 | $0.00690 |
| Sonnet 5 | $0.00027 | $0.00276 |
| Haiku 4.5 | $0.00014 | $0.00138 |
Grade A, and why
aeo-citation-gap-finder 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.

AEO Citation Gap Finder
Source: github.com/psyduckler/aeo-skills Part of: AEO Skills Suite
Compare what different AI models cite for the same prompts. Find gaps in your cross-platform AI visibility.
Why This Matters
Different AI models cite different sources for the same query. Google's AI Overviews (Gemini 3 Flash) use Google Search grounding. ChatGPT uses Bing. Perplexity uses its own search stack. A page that dominates Google AI citations may be invisible in ChatGPT, and vice versa.
This skill identifies those gaps so you can optimize content for cross-platform AI visibility.
How It Works
- Google AI citations — Runs the prompt 20 times through Gemini 3 Flash with
google_searchgrounding. This simulates real AI Overviews and gives reliable citation frequency data. - Web search citations — Searches the same prompt via Brave Search API (or web_search tool). The top organic results approximate what ChatGPT (Bing-powered) and Perplexity would cite, since they all draw from similar web indexes.
- Gap analysis — Compares the two source sets:
- Google-only: Cited by Gemini but not in top web results → Google's AI has unique source preferences
- Web-only: In top web results but not cited by Gemini → traditional SEO winners that AI overlooks
- Both: Cited everywhere → strong cross-platform authority
- Domain tracking — If you specify a domain, shows exactly where it appears vs where it's missing.
Requirements
- Gemini API key (free) — set as
GEMINI_API_KEYenv var - Brave Search API key (optional) — set as
BRAVE_API_KEYenv var. If not set, web search comparison is skipped. - Python 3.9+
- No pip dependencies (stdlib only)
Usage
# Full gap analysis with domain tracking
GEMINI_API_KEY="$GEMINI_API_KEY" \
BRAVE_API_KEY="$BRAVE_API_KEY" python3 scripts/find_gaps.py "best SEO tools for content optimization" --domain acme.com
# Without Brave (Gemini-only analysis)
GEMINI_API_KEY="$GEMINI_API_KEY" python3 scripts/find_gaps.py "best SEO tools for content optimization" --domain acme.com
# JSON output
GEMINI_API_KEY="$GEMINI_API_KEY" \
BRAVE_API_KEY="$BRAVE_API_KEY" python3 scripts/find_gaps.py "best SEO tools for content optimization" --domain acme.com --output json
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aeo-citation-gap-finder is a skill published in the GitHub repository psyduckler/aeo-skills (11 stars, last pushed 3mo ago), licensed MIT. It adds 137 tokens to every session and 1,380 once invoked, about $0.0007 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.
