ai CLAUDE.md

A repository guide for AI assistants working on Straddle’s payment-infrastructure plugin. It explains the project layout, how its skills and commands fit together, and where to find stable technical knowledge or live product information.

In plain words
What is it for?
Use it when developing or maintaining the Straddle AI plugin, especially its skills, slash commands, synchronisation script, product-documentation lookup, and payment-integration guidance.
Why use it?
It gives an assistant the context needed to make accurate changes across a plugin that includes payment workflows, documentation tools, and integrations. This avoids guessing how the repository’s parts connect.

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.

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 B, and why

ai CLAUDE.md scanned grade B 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 2d 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.

Reads MCP configurationmediumAgent snooping

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

Straddle AI Plugin

What this repo is

Claude Code plugin repo for Straddle payment infrastructure. Provides skills, slash commands, and MCP server configuration for AI coding assistants.

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.
