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 | $0.00750 | $0.00750 |
| Opus 5.5 | $0.00300 | $0.00300 |
| Sonnet 5.5 | $0.00150 | $0.00150 |
| Haiku 4.5 | $0.00075 | $0.00075 |
Grade A, and why
DevVerse-SWE-Blog 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 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevVerse Codex Guidance
Core Expectations
- Treat
content/*.mdxas the canonical article store. The SQL article schemas insupabase/are not the runtime source of article content. - Prefer code over README when they conflict. Parts of the README are stale.
- Keep changes narrow. This repo has duplicated article parsers and several UI/data contracts that are easy to break with broad refactors.
- Do not read or print real secret values from
.envor.env.*. Use.env.examplefor variable names and expected configuration. - Use
rgandrg --filesfor search.
Architecture Invariants
- Preserve the split between
/and/home. /is the landing page and intentionally hides the navbar./homeis the article browser.- Preserve
.mdx-containerand theh2/h3article heading structure.components/TableOfContents.tsxdepends on both. - Preserve the dark-mode chain across:
- the inline boot script in
app/layout.tsx - the
darkclass on<html> - CSS variables in
app/globals.css provider/DarkModeProvider.tsx
- the inline boot script in
- Preserve the chat response contract across
app/chat/page.tsx,lib/chat-citations.ts, andlib/rag.ts.- assistant answers use bracket citations
- backend appends a trailing
Sources:section - UI strips that section and links citations to
message.sources
MDX Content Contract
- Keep article metadata as a literal
export const metadata = { ... };. - Keep
title,description, andtopicsas literal string/array fields. - Keep
### Author: .... - Keep
> Date: YYYY-MM-DD. - Keep article body starting with a top-level
#heading. - If you change that contract, update all dependent parsers together:
lib/rss.tslib/rag-local.tsscripts/vectorize_articles.mjs- any affected tests
Security Boundaries
- Keep
SUPABASE_SERVICE_ROLE_KEYserver-only. - Treat these routes as security-sensitive:
app/api/verify-email/route.tsapp/api/reset-password/route.ts
- Do not move service-role Supabase code into shared modules imported by client code.
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.
