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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.01401 |
| Opus 5 | $0.00000 | $0.00700 |
| Sonnet 5 | $0.00000 | $0.00280 |
| Haiku 4.5 | $0.00000 | $0.00140 |
Grade A, and why
run scanned grade A with 1 finding 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 2d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agentkernel run
Run a command in a temporary sandbox. The sandbox is created, the command executed, and then cleaned up automatically.
Usage
agentkernel run [OPTIONS] <COMMAND>...
Options
| Option | Description |
|---|---|
-i, --image <IMAGE> |

-p, --profile <PROFILE> |
Security profile: permissive, moderate, restrictive |
-k, --keep |
Keep the sandbox after execution (for debugging) |
-F, --fast |
Use container pool for faster startup (default: true) |
-c, --config <FILE> |
Path to agentkernel.toml config file |
--devcontainer <FILE> |
Path to a JSONC Development Container file |
--auto-devcontainer |

Backend: docker, podman, firecracker, apple, etc. |
--template <NAME> |
Use a template (built-in, local, github:owner/repo/path, or file) |
--ttl <DURATION> |
TTL for kept sandboxes (e.g. 1h, 30m, 3d; default: 1h) |
--branch |
Use git project+branch as sandbox name (reuses existing sandbox) |
--no-network |
Disable network access |
-P, --publish <PORT> |
Port mapping (e.g. 8080:80, 3000). Repeatable. Requires --fast=false. |
--ssh |

Examples
Basic usage
# Auto-detects python image
agentkernel run python3 -c "print('hello')"
# Auto-detects node image
agentkernel run node -e "console.log('hello')"
# Run a script
agentkernel run python3 script.py
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.

run is a command published in the GitHub repository thrashr888/agentkernel (58 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,401 tokens. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
