What is ev-node AGENTS.md?

Repository instructions for ev-node, a Go framework for building sovereign rollups on different data-availability layers. They describe the project, development commands, and tests.

Working on ev-node with its just commands, Go builds, unit tests, integration tests, end-to-end tests, coverage, and linters.

They give coding agents the project’s expected commands and workflow, reducing mistakes when building, testing, linting, or running end-to-end checks.

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	$0.01204	$0.01204
Opus 5	$0.00602	$0.00602
Sonnet 5	$0.00241	$0.00241

Security

Grade A, and why

ev-node 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 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.

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.

Project Overview

ev-node is a sovereign rollup framework built in Go that allows developers to build rollups on any DA layer. It provides a modular architecture where components like the data availability layer, executor, and sequencer can be plugged in.

Build and Development Commands

Uses just as the command runner. Run just help to list all recipes.

Building

just build - Builds the Testapp CLI to ./build/testapp
just install - Installs Testapp CLI to your Go bin directory
just build-all - Builds all ev-node binaries
just docker-build - Builds Docker image tagged as evstack:local-dev

Testing

just test - Runs unit tests for all go.mod files
just test-integration - Runs integration tests (15m timeout)
just test-e2e - Runs end-to-end tests (requires building binaries first)
just test-cover - Generates code coverage report
just test-all - Runs all tests including Docker E2E tests

Linting and Code Quality

just lint - Runs all linters (golangci-lint, markdownlint, hadolint, yamllint, goreleaser check, actionlint)
just lint-fix - Auto-fixes linting issues where possible
just vet - Runs go vet

Development Utilities

just deps - Downloads dependencies and runs go mod tidy for all modules
just proto-gen - Generates protobuf files (requires Docker)
just mock-gen - Generates mocks using mockery
just run-n 3 - Run multiple nodes locally (default: 1)

Code Architecture

Core Package Structure

The project uses a zero-dependency core package pattern:

core/ - Contains only interfaces and types, no external dependencies
block/ - Block management, creation, validation, and synchronization
pkg/p2p/ - Networking layer built on libp2p
pkg/sequencers/ - Modular sequencer implementations
apps/testapp/ - Reference implementation for testing

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.
