What is slug-wallet AGENTS.md?

Repository instructions for Slug Wallet, a project that handles guarded wallet payments. They document the commands, important files, environment variables, and test layout that coding agents need to work in the repository.

They help agents choose commands, find implementation files, configure live mode, and run unit or end-to-end checks.

They give an agent the project-specific information needed to build, test, verify, and run the code correctly.

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	$0.00556	$0.00556
Opus 5.5	$0.00222	$0.00222
Sonnet 5.5	$0.00111	$0.00111
Haiku 4.5	$0.00056	$0.00056

Security

Grade A, and why

slug-wallet 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 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.

Build, test, and development commands for AI agents working in this repo.

Commands

npm run build          # TypeScript compile → dist/
npm test               # vitest unit tests (67 tests)
npm run check          # build + test in one shot (use this to verify changes)
npm run verify:harness # end-to-end: interceptor + MockSigner, no subprocess
npm run verify:mcp     # end-to-end: spawns dist/server.js as MCP subprocess
npm run relay          # start fee relay locally (requires .env)

Key files

File	Purpose
`src/server.ts`	MCP server entrypoint (`slug-wallet-mcp` bin)
`src/relay.ts`	Fee relay HTTP server (`slug-wallet-relay` bin)
`src/mcp.ts`	Tool definitions: slug_fetch, get_wallet_address, get_daily_spend
`src/interceptor.ts`	HTTP 402 intercept + invoice parsing
`src/firewall.ts`	Domain/amount/daily-limit guard
`src/signer.ts`	Shared types, EIP-3009 constants, splitSignature
`src/cdpPaymentSigner.ts`	Live signer using Coinbase CDP MPC
`src/feeSigner.ts`	Signs fee-only EIP-3009 authorizations
`src/ledger.ts`	SpendLedger + FeeQueue (in-memory and file-backed)

Env vars needed for live mode

CDP_API_KEY_ID
CDP_API_KEY_SECRET
CDP_WALLET_SECRET
SLUG_RELAY_PRIVATE_KEY
SLUG_RELAY_AUTH_TOKEN
SLUG_WALLET_RELAY_URL=http://127.0.0.1:4022

Dev mode (no real keys): set SLUG_WALLET_DEV_SIGNER=1.

Test structure

Tests live in tests/. Each test file imports directly from src/ — no subprocess or network access except:

tests/relay.test.ts starts a real http.Server on a random port (loopback only, mocked writeContract)
tests/mcpIntegration.ts and tests/integration.ts are harness scripts, not vitest files

TypeScript

ESM only ("type": "module" in package.json)
Target: Node 20+
Strict mode enabled
Imports use .js extensions (compiled output convention)

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.
