Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.03886 | $0.03886 |
| Opus 5 | $0.01943 | $0.01943 |
| Sonnet 5 | $0.00777 | $0.00777 |
| Haiku 4.5 | $0.00389 | $0.00389 |
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 today.
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 — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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/— thenpm create bestaxscaffolder (has its own CLAUDE.md)bestax-migrate/— thebestax-migratecodemod CLI (has its own CLAUDE.md)bestax-mcp/— thebestax-mcpMCP server; itsdata/index is generated (has its own CLAUDE.md)skills/— Agent Skills, a shipped product bundled into create-bestax (has its own CLAUDE.md)telemetry-worker/— Cloudflare Worker ingesting the CLIs' opt-in telemetry (deployed from CI bydeploy-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 inworkflows/)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 fromskills/(pnpm gen:skills)
Toolchain
Node 22 locally (.nvmrc; CI runs Node 24) and [email protected] (pinned via packageManager; run
corepack enable once). Install with pnpm install --frozen-lockfile for CI parity.
Commands
pnpm all # the pre-PR gate: build, typecheck, test+coverage, bundle:stats, lint, format:check, storybook build
pnpm test # jest (bulma-ui + create-bestax + bestax-migrate + bestax-mcp)
pnpm test:coverage # coverage — thresholds live in each package's jest config (see below)
pnpm lint # eslint
pnpm typecheck # tsc --noEmit
pnpm format # prettier --write (format:check to verify; covers md/mdx too)
pnpm gen:catalog # regenerate the skills component catalog (CI fails if stale)
pnpm gen:mcp # regenerate the MCP server's data index (CI fails if stale)
pnpm gen:skills # regenerate the skill install rosters (conformance fails if stale)
pnpm gen # all four generators (api docs, catalog, MCP index, skill rosters)
pnpm docs # Docusaurus dev server :3000
pnpm storybook # Storybook dev server :6006
pnpm exec turbo run test --filter=@allxsmith/bestax-bulma # scope any task to one package
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.
