What is l402-kit AGENTS.md?

A navigation and contribution guide for the l402-kit software project. It tells coding agents which project documents to read for orientation, deployment, debugging, security, and code changes.

Use it when working on l402-kit to find architecture and operations documentation, understand its Lightning and HTTP payment-related protocols, locate source code and tests, and follow contribution requirements.

Large repositories are difficult to understand safely because important information is spread across many files. This guide points to the right source of information and records project rules that should remain unchanged.

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	$0.01570	$0.01570
Opus 5.5	$0.00628	$0.00628

Security

Grade A, and why

l402-kit AGENTS.md scanned grade A with 1 finding 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.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Why this file: anyone driving this repo from an AI agent (Claude Code, Cursor, etc.) reads this first to orient. Structured for grep + cheap context.

Companion: CLAUDE.md (Claude-specific ops), HANDBOOK.md (deep walkthrough), ARCHITECTURE.md (where-is-what).
