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 | $0.03040 | $0.03040 |
| Opus 5.5 | $0.01216 | $0.01216 |
| Sonnet 5.5 | $0.00608 | $0.00608 |
| Haiku 4.5 | $0.00304 | $0.00304 |
Grade A, and why
openblog AGENTS.md 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 4d 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 — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — OpenBlog
You are editing OpenBlog, an open-source, Git-based CMS for blogs — implemented as an agent-native blog module for product websites. Content lives in Git (Markdown + frontmatter); you maintain routes, theme, site chrome, and SEO primitives (sitemap, RSS, robots, JSON-LD) through the repo. For site-wide SEO, GEO, keyword strategy, and marketing-page optimization, use marketing-skills — OpenBlog only guarantees blog-path SEO primitives.
Existing product site? Read INTEGRATION.md before editing chrome.
Agent: route the user first
When someone opens this repo without a clear task, ask which path applies before editing files:
| User situation | Point them to | Skill |
|---|---|---|
Has a product / marketing site — wants /blog, matching nav/logo |
INTEGRATION.md | blog-cms → integrate-product-site |
| Greenfield — new blog, local demo, no existing site | Quick start → scaffold (create-openblog) |
blog-cms → setup-blog-module |
| Module already wired — add or edit a post | Content model in this file | create-post (optional) |
| Pre-merge / deploy checks on blog posts | Validate + build | validate-blog-seo |
| Ready to merge and deploy | Git → CI checklist | publish (optional) |
Suggested prompt to show the user:
OpenBlog has two common paths:
- Existing product site → integrate
/blogvia INTEGRATION.md (recommended)- Try it first → clone the repo, then
npm run create-openblog -- my-blog(ornpm install && npm run devfor a quick demo) Which applies to you? If you have a product site URL, share it.
Do not default to create-openblog if they mention an existing website, product URL, chrome, or navbar alignment.
Contributions: Upstream PRs to this repo are enterprise-only (design-token or component/platform partners). Do not encourage individual users to open PRs — point them to INTEGRATION.md, Issues, or CONTRIBUTING.md for enterprise partnership inquiries.
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.
