bestax: Instructions file for Claude Code

CLAUDE.md

bestax CLAUDE.md is an instructions file for Claude Code from allxsmith/bestax. It costs 6,961 tokens per session, scanned A, original, MIT.

A project guide for Bestax, a TypeScript library of React interface components styled with Bulma, a CSS framework. The repository is a monorepo, meaning one repository contains several related packages and applications.

In plain words
What is it for?
Use it when changing the component library, documentation site, scaffolding tools, migration CLI, agent skills, telemetry worker, or automation workflows.
Why use it?
It explains which parts of the repository affect releases, production services, documentation, and security. This helps agents avoid treating release-affecting files as ordinary cosmetic code.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions .claude-plugin; mentions CLAUDE.md; mentions Claude Code.

This is allxsmith/bestax's own configuration. It tells Claude Code how to work on bestax itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything bestax configures →

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.

Security

Grade A, and why

bestax 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 5d 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.

bestax

React component library for Bulma v1 in TypeScript. pnpm monorepo orchestrated by turbo:

  • bulma-ui/ — the library, published as @allxsmith/bestax-bulma (has its own CLAUDE.md)
  • docs/ — Docusaurus site → https://bestax.io (has its own CLAUDE.md)
  • create-bestax/ — the npm create bestax scaffolder (has its own CLAUDE.md)
  • bestax-migrate/ — the bestax-migrate codemod CLI, and in codemod/ its Codemod Registry wrapper (has its own CLAUDE.md)
  • bestax-mcp/ — the bestax-mcp MCP server; its data/ index is generated (has its own CLAUDE.md)
  • eslint-plugin/ — @allxsmith/eslint-plugin-bestax, lint rules for the library; its src/generated/ metadata is generated (has its own CLAUDE.md)
  • skills/ — Agent Skills, a shipped product bundled into create-bestax (has its own CLAUDE.md)
  • templates/: Bulma templates rebuilt with bestax, each a create-bestax project the docs Templates page lists, published to a mirror StackBlitz opens; not workspace packages (has its own CLAUDE.md, the porting guide)
  • plugin/: the hand-written inputs of the bestax coding-agent plugin, which is generated into allxsmith/bestax-skills (see "The bestax plugin" below)
  • telemetry-worker/ — Cloudflare Worker ingesting the CLIs' opt-in telemetry (deployed from CI by deploy-worker.yml — a merged change under it ships to production immediately)
  • eval/agent-loop/ — cold-start eval harness: does an unassisted agent build correctly when given one of our guidance channels (the skills, the MCP server, both)? Frozen rubric, its own README
  • .github/ — CI and AI-automation workflows, human-authored only (has its own CLAUDE.md, which is the security contract for anything in workflows/)
  • scripts/gen-component-catalog.mjs — generates the skill component catalog (pnpm gen:catalog)
  • scripts/gen-mcp-index.mjs — generates the MCP server's data index (pnpm gen:mcp)
  • scripts/gen-skills-rosters.mjs — writes the skill install rosters from skills/ (pnpm gen:skills)

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.
