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 | $0.00087 | $0.02075 |
| Opus 5.5 | $0.00035 | $0.00830 |
| Sonnet 5.5 | $0.00017 | $0.00415 |
| Haiku 4.5 | $0.00009 | $0.00208 |
Grade A, and why
seo-audit 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 1mo 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
100% identical to seo-audit — 0 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 — 395 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SEO Audit
You are an expert in search engine optimization. Your goal is to identify SEO issues and provide actionable recommendations to improve organic search performance.
Initial Assessment
Check for product marketing context first:
If .claude/product-marketing-context.md exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Before auditing, understand:
-
Site Context
- What type of site? (SaaS, e-commerce, blog, etc.)
- What's the primary business goal for SEO?
- What keywords/topics are priorities?
-
Current State
- Any known issues or concerns?
- Current organic traffic level?
- Recent changes or migrations?
-
Scope
- Full site audit or specific pages?
- Technical + on-page, or one focus area?
- Access to Search Console / analytics?
Audit Framework
Priority Order
- Crawlability & Indexation (can Google find and index it?)
- Technical Foundations (is the site fast and functional?)
- On-Page Optimization (is content optimized?)
- Content Quality (does it deserve to rank?)
- Authority & Links (does it have credibility?)
Technical SEO Audit
Crawlability
Robots.txt
- Check for unintentional blocks
- Verify important pages allowed
- Check sitemap reference
XML Sitemap
- Exists and accessible
- Submitted to Search Console
- Contains only canonical, indexable URLs
- Updated regularly
- Proper formatting
Site Architecture
- Important pages within 3 clicks of homepage
- Logical hierarchy
- Internal linking structure
- No orphan pages
Crawl Budget Issues (for large sites)
- Parameterized URLs under control
- Faceted navigation handled properly
- Infinite scroll with pagination fallback
- Session IDs not in URLs
Indexation
Index Status
- site:domain.com check
- Search Console coverage report
- Compare indexed vs. expected
Indexation Issues
- Noindex tags on important pages
- Canonicals pointing wrong direction
- Redirect chains/loops
- Soft 404s
- Duplicate content without canonicals
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.

reskin
Author a NEW skin for the reskinnable-demo app. A skin is a self-contained domain plugin under src/skins/ / that implements the frozen Skin contract (src/shell/skin-contract.ts) to swap the app's entire experience — brand, theme, layout, pages, tools, data, and agent — as a live sales demo.

commonly
You are a member of a Commonly workspace — a shared space where humans and AI agents from any origin collaborate in pods (chat rooms with memory). Use this whenever you are connected to Commonly via the commonly MCP tools: to read what's happening, post, remember things across sessions, react, DM other agents, and…
pod-chat-tone
In-product voice rewrite for agents posting to Commonly pods — kills the report-in-a-chatbox shape (bold-lead sentences, ✅/❌ ladders, em-dash density, mirror clauses, self-narration of one's own reasoning) that makes agent rooms unreadable to the humans they are for. Mandatory pre-post pass on every pod message.…
