Written for Codex and OpenCode: the file is AGENTS.md.

This is fetchai/agentverse-skills's own configuration. It tells Codex and OpenCode how to work on agentverse-skills 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 agentverse-skills 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 B, and why

agentverse-skills AGENTS.md scanned grade B with 2 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 1mo 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.

Instructions for AI Agents Working on This Repo

What This Repo Is

This is a collection of portable agent skills (SKILL.md format) that enable AI coding agents to interact with Fetch.ai's Agentverse platform programmatically.

Repo Structure

  • skills/ — Each subdirectory is a self-contained skill
    • SKILL.md — The skill definition (what you read to learn the skill)
    • scripts/ — Runnable Python scripts (only dependency: requests)
    • references/ — Deep documentation and protocol details
  • examples/ — Worked examples showing real outputs
  • docs/ — Reference documentation (API, auth, troubleshooting)

How to Add a New Skill

  1. Create skills/<skill-name>/SKILL.md with proper frontmatter
  2. Create skills/<skill-name>/scripts/<script>.py — self-contained, CLI-ready
  3. Add entry to the table in README.md
  4. Add a worked example in examples/ if non-trivial

Skill Script Requirements

  • Self-contained: Only needs requests library (stdlib + requests)
  • CLI interface: Uses argparse, runnable from command line
  • JSON output: Results go to stdout as valid JSON
  • Error handling: Logs/errors go to stderr, exit code 1 on failure
  • Env vars: Uses AGENTVERSE_API_KEY (or ASI_ONE_API_KEY for ASI:One)
  • Helpful errors: If env var missing, print instructions on how to get one
  • Apache 2.0 license header

SKILL.md Format

Follow the SKILL.md specification:

---
name: skill-name
description: >
  One-paragraph description of what this skill does.
  Include trigger phrases and key capabilities.
license: Apache-2.0
compatibility: Python 3.8+, network access, AGENTVERSE_API_KEY env var
metadata:
  version: "1.0.0"
  author: "Fetch.ai"
  last-updated: "2026-04-20"
allowed-tools: Read Bash(python3 *) Bash(curl *) Bash(pip install requests)
---

Key Technical Facts

  • Base URL: https://agentverse.ai
  • Auth: Authorization: Bearer {AGENTVERSE_API_KEY}
  • Working API version: V1 (/v1/hosting/agents, /v1/almanac/...)
  • Code upload format: {"code": json.dumps([{"language":"python","name":"agent.py","value":"..."}])}
  • Hosted env: agent is pre-created — do NOT use Agent() or .run()
  • Logs are output: Use ctx.logger.info() — no stdout/stderr in hosted env
  • Image gen timing: ACK ~1s, text response ~3s, image response ~30s

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.
