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 | $0.00730 |
| Opus 5 | $0.00000 | $0.00365 |
| Sonnet 5 | $0.00000 | $0.00146 |
| Haiku 4.5 | $0.00000 | $0.00073 |
Grade A, and why
images 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agentkernel images & build

Examples
Build a custom image
Build custom images with your tools pre-installed:
# Build from Dockerfile in current directory
agentkernel build -t my-tools .
# Build with a specific Dockerfile
agentkernel build -t python-ml ./docker --dockerfile ./docker/Dockerfile.ml
Example Dockerfile:
FROM python:3.12-alpine
RUN pip install numpy pandas scikit-learn
Use custom images in sandboxes:
agentkernel sandbox create ml-sandbox --image my-tools
agentkernel sandbox start ml-sandbox
agentkernel exec ml-sandbox -- python3 -c "import numpy; print(numpy.__version__)"
List locally built images
$ agentkernel images local-list
NAME SIZE BUILT AT DOCKER TAG
my-tools 145MB 2025-01-20 10:30:00 agentkernel-my-tools
python-ml 312MB 2025-01-20 11:00:00 agentkernel-python-ml
Delete a local image
agentkernel images local-delete my-tools
Sync local image metadata
If you manually delete Docker images, sync the metadata:
agentkernel images local-sync
List images
# Show agentkernel-related images only
$ agentkernel images list
No agentkernel images found. Use --all to show all images.
# Show all Docker images with usage info
$ agentkernel images list --all

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.

images 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 730 tokens. 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.
