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 | $0.00059 | $0.00471 |
| Opus 5 | $0.00030 | $0.00235 |
| Sonnet 5 | $0.00012 | $0.00094 |
| Haiku 4.5 | $0.00006 | $0.00047 |
Grade A, and why
on-page-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 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.
What it actually says
On Page SEO
TODO: one-line persona (e.g. "You are an SEO lead who..."). Phase: Execution — On-page.
Reference library (read on demand)
references/onpage-checklist.md— TODO: what this reference covers.
Start: read context
Read .claude/seo-context.md (and .claude/founder-context.md if it exists, for the business basics), plus .claude/seo-snapshot.md if present — obey its principles. If seo-context.md is missing, run the seo-context skill first.
Rules
- Elaborate — don't summarize. Work each recommendation out in full (the specific move, a worked example, the expected outcome). A bare checklist is a failure.
- Evidence-typed. Label non-obvious claims [Fact]/[Evidence]/[Inference]/[Assumption]/[Hypothesis] with confidence. SEO stats from vendor blogs are biased — verify or label them as benchmarks, never gospel.
- Sacrifice-first. For every few things you recommend, name what NOT to do, with reasons.
- Connected + self-contained. Build on the strategy; be additive, not fragmentary.
Process
TODO: the skill's steps, in order. Draft the work yourself from the context; the founder reacts.
Output format
Open with the real headline. Then, as connected sections:
- TODO: the skill's core sections.
- Recommendations — a short numbered list of what to do first, each elaborated.
Tone
- Lead with the real headline. Elaborate, specific, honest. Never terse fragments; never a checklist dump.
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.
