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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00152 | $0.01625 |
| Opus 5 | $0.00076 | $0.00813 |
| Sonnet 5 | $0.00030 | $0.00325 |
| Haiku 4.5 | $0.00015 | $0.00162 |
Grade A, and why
parasite-seo 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.

SEO: Parasite SEO
Guides parasite SEO (also "barnacle SEO")—publishing optimized content on high-authority third-party platforms (Medium, Reddit, LinkedIn, Grokipedia, etc.) to leverage their domain strength for rankings and backlinks, bypassing the need to build your own site's authority from scratch.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
What Is Parasite SEO
Parasite SEO = Placing content on high-authority platforms to leverage their domain strength for rankings and AI citation. Part of "Distributed Authority Engineering."
Instead of waiting months for your own domain to gain trust, you publish on established platforms that Google already trusts. Content can rank on page one within days rather than months because Google crawls these platforms frequently and inherits their domain trust.
Best for: Beginners testing niches; local businesses needing quick leads; demand validation; supplementing traditional SEO.
Why It Works
| Factor | Effect |
|---|---|
| Domain authority | Platforms (DA 90+) rank faster than new sites |
| Crawl frequency | Google crawls Reddit, Medium, LinkedIn often |
| AI citation | ChatGPT, Perplexity cite Reddit, Quora, wikis |
| UGC preference | Algorithm updates favor UGC platforms as trustworthy |
| Technical foundation | High-authority sites have strong technical SEO, fast load, good UX |
Platform Tiers
Platform examples are illustrative only. No endorsement implied.
| Tier | Platform type | Examples | GEO / AI citation |
|---|---|---|---|
| Tier 1 | GEO authority | Medium, Reddit, LinkedIn Articles, Quora | Very high |
| Tier 2 | Technical authority | GitHub, Stack Overflow, Dev.to | High; expertise signals |
| Tier 3–6 | Controlled / entity / wiki | WordPress.com, Blogger, HN, Grokipedia | Varies |
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.
