What is hive CLAUDE.md?

Project instructions for Hive, Hazelcast’s React design system and component library. They describe its tools, folder layout, testing, styling, and code conventions.

Building or changing React and TypeScript components, SCSS module styles, Storybook examples, tests, and shared exports in the Hive repository.

Contributors otherwise have to discover the project’s commands and rules themselves, which can lead to inconsistent components or failed checks.

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	$0.00273	$0.00273
Opus 5.5	$0.00109	$0.00109
Sonnet 5.5	$0.00055	$0.00055
Haiku 4.5	$0.00027	$0.00027

Security

Grade A, and why

hive 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 2mo 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.

What it actually says

Hive — Hazelcast Design System

@hazelcast/ui — React component library and design system.

Stack

React 19, TypeScript, SCSS modules
Storybook 8 for component development (npm run dev)
Jest + Testing Library for unit tests (npm test)
ESLint + Prettier

Key commands

npm run dev       # Storybook on :6006
npm test          # Jest

Code style

Minimize comments — only add them where the logic is non-obvious. Do not add section headers, label-style comments (e.g. // Colors, // Sizes), or comments that restate what the code already says.

Conventions

Components export from src/index.ts
Stories live in __stories__/, tests in __tests__/
CSS modules (.module.scss) per component
Lint-staged runs on commit (ESLint)

Changes

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.
