agentv-dev

A collection of AgentV CLI guides for evaluating, benchmarking, reviewing, and governing AI agents. AgentV is a command-line tool for working with these agent checks.

In plain words
What is it for?
Use it to run or write evaluations, migrate or review evaluation files, analyse traces, optimise prompts, and create governance checks.
Why use it?
It helps you choose the right procedure for testing agent quality, examining execution traces, improving prompts, or checking governance rules.

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

agentv-dev 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 yesterday.

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

The full skill content is bundled with the AgentV CLI and always version-matched to it. Load the specific skill you need. If the task is not about AgentV evals, trace analysis, optimization, or governance, no AgentV skill applies.

Quick Start

  1. Ensure agentv CLI is on PATH (run agentv --help to verify)
  2. Pick the skill from the table above
  3. Run agentv skills get <skill-name> to load it
  4. Follow the instructions in the loaded skill

CLI Location

If agentv is not on PATH, check:

  • node_modules/.bin/agentv (project-local install)
  • ~/.local/bin/agentv (global user install)
  • Run from source: bun apps/cli/src/cli.ts <command>
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.

agentv-dev is a skill published in the GitHub repository EntityProcess/agentv (15 stars, last pushed 1mo ago), licensed MIT. It adds 70 tokens to every session and 495 once invoked, about $0.0003 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.
