eve

eve is a skill for Claude Code, Codex from ComposioHQ/composio. It costs 47 tokens per session (248 once invoked), scanned A, original, MIT.

A framework guide for building durable backend AI agents with eve. Eve stores an agent’s instructions, skills, tools, connections, channels, schedules, and evaluations as files.

In plain words
What is it for?
Use it to create, edit, or troubleshoot eve projects, including agent instructions, tools, integrations, sandboxes, subagents, schedules, and evaluations.
Why use it?
It gives you the project’s source of truth when creating or debugging an eve agent, so its behavior and setup stay organized on disk.

About the project

Composio is a software toolkit that gives AI agents access to authenticated tools for interacting with apps and services. Developers use its SDKs, command-line interface, sessions, and sandbox to build agents that can carry out actions. The catalogue add-ons support workflows for using Composio with coding agents.

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 5d 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.

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.

See references/source-of-truth.md for the repo-local handoff boundary.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

eve is a skill published in the GitHub repository ComposioHQ/composio (30,055 stars, last pushed today), licensed MIT. It adds 47 tokens to every session and 248 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
