What is x402-grocery AGENTS.md?

A set of repository instructions for coding agents working on the x402-grocery project. It describes the project, its TypeScript layout, setup commands, checks, and working rules.

Use it when installing, building, type-checking, testing, or modifying the x402-grocery repository.

It gives an agent repository-specific facts instead of making it guess how the project is organised or tested. This helps it follow the project's conventions before changing code.

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	$0.00506	$0.00506
Opus 5.5	$0.00202	$0.00202
Sonnet 5.5	$0.00101	$0.00101
Haiku 4.5	$0.00051	$0.00051

Security

Grade A, and why

x402-grocery AGENTS.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 27d 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.

AGENTS.md

Operating notes for AI coding agents (Claude Code, Codex, Cursor, Copilot and others) working in this repository. Everything here is derived from the files actually in the tree, so trust it over guesses, and update it when the facts change.

Run the test and lint commands above before you consider a change finished. If a command fails on code you did not touch, say so in your report instead of silently skipping it.

Conventions

TypeScript runs in strict mode; do not loosen tsconfig.json to make an error go away.
.env files are gitignored; never commit credentials, and read configuration from environment variables.
Commit messages follow Conventional Commits (type(scope): summary), matching the existing history.
Read the surrounding code before adding to it, and match its naming, file organisation and error-handling style.
Keep README.md accurate: if a change alters behaviour, commands or configuration, update the docs in the same commit.
Do not leave TODO comments, stub functions, placeholder data or commented-out code behind. Finish what you start or leave it out.
Small, focused commits with a subject line that describes the change, not the act of committing.

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.
