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 | $0.00129 | $0.01423 |
| Opus 5 | $0.00064 | $0.00711 |
| Sonnet 5 | $0.00026 | $0.00285 |
| Haiku 4.5 | $0.00013 | $0.00142 |
Grade A, and why
seo-competitor 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 10d 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.
This is a copy
92% identical to seo-competitor — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SEO Competitor Analysis
Compare a site to its competitors and find the gaps worth closing. Stack-agnostic. Tool-friendly but tool-optional.
When to use
- Identifying which competitors to study
- Finding content gaps (topics they cover, you do not)
- Finding backlink gaps (sites linking to them, not you)
- Understanding why a specific competitor outranks the user
- Benchmarking authority, technical posture, and content depth
When NOT to use
- Single-page optimization (use
seo-onpage) - Initial keyword research with no competitors yet identified (use
seo-keywordfirst to find them) - Auditing one's own existing content (use
seo-content-audit)
Required inputs
- The user's site
- 3 to 5 named competitors (or the topic area, if competitors are not yet identified)
- Access to a keyword tool, a backlink tool, and any crawler
If competitors are unknown, start by listing the top 10 ranking domains for the user's top 10 priority keywords. Pick the 3 to 5 that appear most often.
Where competitor traffic estimation is the input you need (relative scale, channel mix, audience overlap), Similarweb MCP is the strongest source. Pair with Ahrefs (for backlink and keyword overlap) and Semrush (for SERP feature presence and SEO-PR overlap). Each platform gives a different cut of the same competitive landscape; using them together produces sharper signal than any one alone.
The framework: 5 angles
Competitor analysis covers five angles. Run all five for a full picture, or pick two or three for a focused investigation.
1. SERP overlap
Where do you and the competitor compete head-to-head?
- For each priority keyword, who ranks in the top 10?
- For each top-10 ranking, what page type wins (article, product, comparison, video)?
- Are there SERP features (featured snippet, AI overview, video, image pack) one party holds and the other does not?
- Which queries do competitors rank for that the user does not? (the content gap)
2. Content depth
What does their winning content look like?
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.
