Agent Creation & Management

Agent Creation & Management is a skill for Claude Code, Codex from llaa33219/casabot. It costs 15 tokens per session (1,988 once invoked), scanned D, original, Apache-2.0.

A manual for creating and managing isolated helper agents using Podman, a tool for running processes in containers.

In plain words
What is it for?
Installing or verifying Podman and creating, configuring, and managing Podman-based sub-agents.
Why use it?
It lays out the checks and setup needed before creating sub-agents, including installation and rootless configuration choices.

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 D, and why

Agent Creation & Management scanned grade D 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 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.

Agent Creation & Management

This manual explains how the base agent creates and manages podman-based sub-agents.


1. Install podman

podman is needed before creating sub-agents.

Step 1: Check if podman is already installed

which podman && podman --version

If podman is found, skip to Section 2.

Step 2: Gather system information

Try to detect as much as possible automatically before involving the user.

# Detect distro
cat /etc/os-release

# Check if sudo is available
sudo -n true 2>/dev/null && echo "sudo: available" || echo "sudo: not available"

If auto-detection fails or sudo is unavailable, ask the user for clarification. You may also ask about preferences like rootless mode or custom storage locations if relevant.

Step 3: Install podman

# Debian / Ubuntu
sudo apt update && sudo apt install -y podman

# Fedora / RHEL / CentOS
sudo dnf install -y podman

# Arch Linux
sudo pacman -S podman

# openSUSE
sudo zypper install -y podman

If rootless mode is desired, configure subuid/subgid:

sudo usermod --add-subuids 100000-165535 --add-subgids 100000-165535 $(whoami)
podman system migrate

Step 4: Verify installation

podman --version
podman info

Consider using the memory skill to save the detected distro and podman version for future reference.

2. Configure podman storage

Check the path where container images and layers are stored, and verify sufficient disk space.

# Check storage path
podman info --format '{{.Store.GraphRoot}}'

# Check disk usage
df -h $(podman info --format '{{.Store.GraphRoot}}')

If space is insufficient, graphroot in ~/.config/containers/storage.conf can be adjusted.

3. Create sub-agent container

All sub-agent containers should be assigned the casabot label for identification.

# Create a new agent container
podman run -d \
  --name <agent-name> \
  --label casabot=true \
  -v ~/casabot/workspaces/<agent-name>:/workspace \
  -v ~/casabot/skills:/skills:ro \
  node:20-slim sleep infinity

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.

Agent Creation & Management is a skill published in the GitHub repository llaa33219/casabot (5 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 15 tokens to every session and 1,988 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
