What is mdread CLAUDE.md?

Repository coding rules for qml4j, a Java library or application whose specific purpose is not described in the input. The rules cover imports, keeping classes and methods focused, and using dispatch and polymorphism.

Use it when adding or changing Java code, especially imports, classes, methods and tests.

It gives coding agents concrete style constraints for keeping the code understandable and consistent.

Token cost

What it costs to keep this loaded

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	$0.03706	$0.03706
Opus 5.5	$0.01482	$0.01482
Sonnet 5.5	$0.00741	$0.00741
Haiku 4.5	$0.00371	$0.00371

Security

Grade A, and why

mdread CLAUDE.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 20d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

A local-first Markdown reader/editor. No framework. It's a Vite + SCSS app of plain ES modules; files are read in the browser and nothing is uploaded unless the user explicitly shares. vite build bundles src/ + public/ into dist/, and dist/ is what Cloudflare serves.

There is now one small backend under worker/, running only for /api/*. It is deliberately blind in two places, and both are load-bearing:

Shares — the browser seals a bundle with AES-GCM and the key travels in the URL fragment, which is never transmitted. Do not "improve" this by moving encryption server-side or by putting the key in a query string or path segment.
Vault (synced share links and documents the user explicitly saved) — encrypted with a key stretched from the user's master password via PBKDF2, client-side. The server stores SHA-256(email) and blobs. Do not add a password-reset flow: there is nothing to reset, and adding one would mean holding the key.

Reading and editing local files still never touch the network — the vault is opt-in per document, via Add to vault in the topbar. That button lives with the document it acts on, not in the sidebar; the sidebar panel previews the five most recent and hands off to #vaultDlg (the full, searchable vault) via "Show all".

Vault storage is split deliberately. The index (vault:<acct>) holds share links plus a document listing (id, name, path, size, updatedAt). Each document body is its own key (vaultdoc:<acct>:<id>), so saving one document doesn't rewrite the whole blob and the index stays cheap to fetch on unlock. Bodies are never cached in plaintext locally — only the index is, so the sidebar can render before anything is decrypted.

Naming: the product/UI is "mdread" (and wrangler.jsonc/package.json name), but the directory, code comments, IndexedDB database, and localStorage keys all use markread. Both refer to the same thing — don't "fix" one to match the other.

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.
