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 | $0.00094 | $0.01389 |
| Opus 5 | $0.00047 | $0.00694 |
| Sonnet 5 | $0.00019 | $0.00278 |
| Haiku 4.5 | $0.00009 | $0.00139 |
Grade A, and why
building-blog 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.
How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Building a Blog (Next.js + Sanity)
Overview
Universal workflow for adding a blog to a Next.js site backed by Sanity CMS. Targets a corporate blog: SEO-first, i18n-ready, performance-budgeted, accessibility-compliant.
SKILL.md is the orchestrator. The spec lives in the two reference files.
Files
blog-technical-requirements.md— §0 intake questionnaire (30+ questions) → §1 Project Profile → §2–§20 universal spec → checklist. Edit only §0 answers and §1 per project.blog-image-style-guide.md— universal template for AI-generated hero imagery via Gemini 3 Pro Image (Nano Banana Pro). Intake questions on top, aesthetic skeleton in the middle, three example slots at the bottom.
Workflow
Step 1 — Scan the host project (before asking anything)
Read what's already there. Pre-filling answers from detected values is much better than asking the user. Look for:
package.json— Next.js version,next-intl, Sanity packages, Tailwind,framer-motionnext.config.{ts,js,mjs}— existingimages.formats, i18n configsrc/messages/**,src/i18n/**,messages/**— current locale setsrc/app/[locale]/**orapp/[locale]/**— routing patterntailwind.config.*,globals.css, design-system files — tokens, fontsCLAUDE.md,AGENTS.md,GEMINI.md— project conventions and approved overrides- Existing
sanity-studio/orstudio/folder app/layout.{tsx,jsx}— fonts, analytics, motion configpublic/brand/**,public/logo*— publisher logositemap.ts,robots.ts— existing routes.env*files — names of already-set env vars (do not log secret values)
Record findings as a brief "Detected" list before the questionnaire.
Step 1.5 — Fetch the latest docs for the stack you'll touch
Spec opinions can drift from upstream reality. Before implementing, pull current docs for the libraries you will actually use on this project. Do not skip this — the spec was last audited at a fixed point in time, and Next.js / Sanity / next-intl ship breaking changes more often than this skill is updated.
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.

building-blog is a skill published in the GitHub repository BuildShipGrowRepeat/nextjs-sanity-blog-skill (8 stars, last pushed 3mo ago), licensed MIT. It adds 94 tokens to every session and 1,389 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
