go-crypto-wallet: Instructions file for Codex

AGENTS.md

go-crypto-wallet AGENTS.md is an instructions file for Codex, OpenCode from hiromaily/go-crypto-wallet. It costs 1,403 tokens per session, scanned A, original, MIT.

Project instructions for coding agents working on a multi-signature cryptocurrency wallet, including its architecture and security priorities.

In plain words
What is it for?
Use it when modifying or reviewing the go-crypto-wallet codebase.
Why use it?
It gives the agent project-specific boundaries so changes protect private keys, preserve layer separation, and follow the existing workflow.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions AGENTS.md.

This is hiromaily/go-crypto-wallet's own configuration. It tells Codex and OpenCode how to work on go-crypto-wallet itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything go-crypto-wallet configures →

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 A, and why

go-crypto-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 7d 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.

Agent Guidelines for go-crypto-wallet

This document defines the behavior and values for AI agents working on this project. For detailed documentation, see llms.txt and ARCHITECTURE.md.

Project Identity

  • Type: Multi-signature cryptocurrency wallet (BTC, BCH, ETH, XRP, ERC-20)
  • Security Model: Offline cold wallets (keygen, sign) + Online watch wallet
  • Architecture: Clean Architecture with strict layer separation
  • Status: Under refactoring based on Clean Code principles

Core Values (Priority Order)

  1. Security First - Private key protection is non-negotiable
  2. Clean Architecture - Domain layer has ZERO infrastructure dependencies
  3. Single Source of Truth (SSOT) - One authoritative location for each piece of information
  4. Incremental Changes - No breaking changes without rollback plan
  5. Code Quality - Follow language-specific linting and testing standards

Expected Behavior

Always Do

  • Check current branch before starting any task (see git-workflow skill)
  • Read relevant documentation before making changes
  • Run verification commands after code changes
  • Wrap errors with context using fmt.Errorf("context: %w", err)
  • Consider impact on offline wallet operations

Never Do

  • ❌ Log private keys or sensitive information
  • ❌ Edit files marked DO NOT EDIT (auto-generated)
  • ❌ Push directly to main branch
  • ❌ Run git merge or gh pr merge
  • ❌ Run protoc or buf commands directly (always use Makefile targets like make proto, make proto-ts)

Ask Before

  • Making security-related changes
  • Breaking changes to public APIs
  • Changes affecting multiple layers

SSOT Structure

When modifying rules, skills, or documentation, always edit the SSOT location.

AI Agent Configuration

Category SSOT Location Other Locations
Rules .claude/rules/*.md .cursor/rules/*.mdc (auto-generated)
Skills .claude/skills/*/SKILL.md .cursor/skills/ (symlink)

Changes

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.
