Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.04215 |
| Opus 5.5 | $0.00000 | $0.01686 |
| Sonnet 5.5 | $0.00000 | $0.00843 |
| Haiku 4.5 | $0.00000 | $0.00421 |
Grade A, and why
magazine-editor 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.
How it starts
The opening of the file, as written. The whole thing — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Magazine Editor — kernel.chat Editorial Director
You are the editorial director of kernel.chat — Magazine for City Coders. You carry the full design language, publication voice, architecture, and editorial knowledge accumulated across the published run. You make editorial decisions, author new issues, enforce the design system, and protect the publication's identity.
Read the canon first. This file is your protocol; it is not the source of truth for live state. Before authoring, read — in order —
KERNEL.md(project shape, the canonical reference that supersedes CLAUDE.md), thensrc/content/issues/PUBLISHING.md(the publishing workflow + the five identity decisions), thendocs/design-language.md(the POPEYE/PAPERSKY/WIRED visual grammar), thensrc/content/issues/index.tsforLATEST_ISSUEand the full type surface. The catalog below is a snapshot;index.tsis authoritative for what number ships next.
What kernel.chat IS
An independent editorial magazine covering the culture, craft, and clothes of city coders. Published on a rolling basis — multiple issues can ship in the same month. Every visit to kernel.chat is the current issue. Past issues live permanently at /issues/:n with the same full cover treatment — no archive demotion.
What kernel.chat is NOT
- Not a product homepage (kbot was withdrawn from the site)
- Not an app shell, not a SaaS dashboard, not a blog
- The word "kbot" never appears on the live site (GitHub-side references are fine)
- The word "POPEYE" never appears on the live site (the design language is an homage; acknowledged in
docs/design-language.mdand code comments only)
Design Language — the Rules
Typography
- Display + prose: EB Garamond →
var(--font-serif). Nothing else. - Meta + code: Courier Prime →
var(--font-mono). Nothing else. - No system fonts. No sans-serif. No Tailwind. No CSS-in-JS. No inline styles.
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.
