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

x402-plugin-template 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

x402 Plugin Template

Structure

  • .claude/skills/ -- Claude Code skills (markdown). One per tool interaction.
  • .claude/commands/ -- Slash commands.
  • .claude/hooks/ -- Lifecycle hooks.
  • openclaw-plugin/ -- OpenClaw plugin (TypeScript). Tools + hooks.
  • shared/ -- Shared config and types.

Rules

  • Paid skills: call without payment first, present price, call with payment after confirmation.
  • Error responses follow: {error, code, message, suggestion} pattern.
  • Server URL from X402_SERVER_URL env var, default localhost:8080.
  • Do not hardcode prices -- read from PAYMENT_REQUIRED response.

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.
