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 | $0.00085 | $0.01023 |
| Opus 5.5 | $0.00034 | $0.00409 |
| Sonnet 5.5 | $0.00017 | $0.00205 |
| Haiku 4.5 | $0.00009 | $0.00102 |
Grade A, and why
nextjs-seo-content 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 16d 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.
How it starts
The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Content SEO for Next.js
A page earns traffic by finishing one search task better than the alternatives. Decide the task, then build the page, its links, and its markup around it. Before writing, confirm the URL passes the indexing gate in nextjs-seo-technical.
Read
| Task | Reference |
|---|---|
| Page copy, titles, headings, internal links, intent, programmatic pages, AI-assisted drafting | Content and on-page |
| Blog, article, news, archive, author page, syndication, refresh, translating editorial content | Editorial and publishing |
| SaaS, docs, marketplace, local, jobs, recipes, events, video, app, course, forum, portfolio, real estate, travel | Site types |
A new blog needs the editorial gate and the on-page reference.
Rules
- Publish a page only if it is worth visiting as the only page on the site. Unreviewed bulk machine or AI generation is scaled content abuse. [doc]
- One search task per page. Two pages for the same task compete. Merge them, or make the difference explicit. [practice]
- Change
dateModifiedonly after a substantive edit. Timestamp-only edits earn nothing and erode trust. [doc] - Internal links use descriptive anchor text and reach every page from an indexed page. An orphan is not found by links. [doc]
- Localize copy for the market's search terms. A literal translation of the English keywords misses how that language searches. [practice]
Working method
- Orient. Read the root
AGENTS.mdif the project has one, the route and its rendered output, and the file that builds page metadata. Never read.env. Done when you can name that file. - Frame. Write the URL set, page type, locale or market, and target outcome, one line each. Ask only when an answer changes the work, and state the default you will use if nobody answers. Done when all four lines exist and every open question is asked or carries a stated default.
- Change and verify. Make the smallest change with the project's own helpers. When a server is running and the
nextjs-seo-technicalskill is installed, run itsscripts/verify-seo.mjs(in this starter:bun run seo:verify), then the project's lint and build. Done when every check ends in one of the four verdicts below. - Report, in the shape below.
What ships with it
4 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.
