CLAUDE.md

x402watch CLAUDE.md is an instructions file for Claude Code from printmoneylab/x402watch. It costs 566 tokens per session, scanned A, original, Apache-2.0.

A project instruction file for x402watch, a service that tracks activity in the x402 payment ecosystem using public data, time series, and AI. It describes the project’s stack, coding rules, deployment details, and security requirements.

In plain words
What is it for?
Use it when developing x402watch with its Next.js, FastAPI, PostgreSQL, Redis, blockchain, and payment integrations, or when checking the project’s required coding and deployment practices.
Why use it?
It gives a coding agent the project context and rules needed to make compatible changes. It also records constraints such as keeping secrets out of commits and using specific transports and services.

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.

Opus 5.5 $0.00226 $0.00226

Security

Grade A, and why

x402watch 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 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.
