eve

eve is a skill for Claude Code, Codex from vercel/eve. It costs 47 tokens per session (231 once invoked), scanned A, a copy of eve, Apache-2.0.

A project setup for building long-running backend AI agents with the eve framework. The framework stores an agent’s instructions, tools, connections, channels, schedules, and other parts as files on disk.

In plain words
What is it for?
Creating or maintaining eve projects, including agent instructions, tools, integrations, communication channels, sandboxes, subagents, schedules, and evaluations.
Why use it?
It provides a defined way to create, edit, and debug durable agents instead of keeping their configuration in one temporary process.

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 A, and why

eve 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 4d 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.

Origin

This is a copy

89% identical to eve — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

eve

eve is a filesystem-first framework for durable backend AI agents. An agent is a directory on disk — instructions, skills, tools, connections, channels, subagents, and schedules are all files — and eve compiles and runs it.

Source of truth

The complete documentation ships inside the eve package. Do not rely on this skill for guidance — always read the bundled docs, which match the installed version exactly:

node_modules/eve/docs/

Start with node_modules/eve/docs/README.md. It contains the full index and recommended reading order. Before writing any eve code, read the relevant guide there first.

If eve is not installed yet, install it (npm install eve) or scaffold a new agent with npx eve init <agent-name>, then read the bundled docs.

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.
