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 5.1 | $0.00015 | $0.02540 |
| Opus 5.5 | $0.00006 | $0.01016 |
| Sonnet 5.5 | $0.00003 | $0.00508 |
| Haiku 4.5 | $0.00002 | $0.00254 |
Grade B, and why
crc-cmd scanned grade B 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
2. SSHs into the VM and runs `sudo systemctl poweroff` (faster than ACPI) How it starts
The opening of the file, as written. The whole thing — 282 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CRC Wrapper Commands
Install two wrapper commands (crcstart and crcstop) into ~/.local/bin/ for managing OpenShift Local (CRC). These replace the built-in crc start and crc stop commands with more reliable alternatives.
Background
Why crcstop exists
The built-in crc stop has a hard-coded 120-second timeout in the libvirt machine driver (crc-org/machine-driver-libvirt, pkg/libvirt/libvirt.go). It sends an ACPI shutdown signal via libvirt.Shutdown(), then polls the VM state in a loop of 120 iterations × 1-second sleep. If the VM hasn't stopped by then, CRC force-kills it with virsh destroy.
The problem is the CRC guest OS (RHCOS) routinely takes 2.5–6 minutes to shut down because:
- ~160–186 libcrun containers must stop individually (~2.5 min)
- CRI-O cleanup can take up to its
DefaultTimeoutStopSecof 200 seconds - The
qemu-guest-agentin the VM hasConditionVirtualization=apple, so it's disabled on KVM/libvirt — no guest-agent shutdown path is available
This means crc stop always force-kills the VM on Linux with libvirt.
Why crcstart exists
Created for consistency alongside crcstop. It wraps crc start with pre-flight checks (is the VM already running?) and post-start status display.
Prerequisites
~/.local/binmust be onPATH(Fedora default via~/.bashrc)- CRC installed and configured with libvirt driver
- SSH key exists at
~/.crc/machines/crc/id_ed25519(created by CRC automatically) virshavailable (fromlibvirt-clientpackage)crc-daemon.servicerunning as a systemd user unit
Steps
-
Create
~/.local/binif it doesn't existmkdir -p ~/.local/bin -
Create
~/.local/bin/crcstopwith the script content from thecrcstopscript section below. -
Create
~/.local/bin/crcstartwith the script content from thecrcstartscript section below. -
Make both executable
chmod +x ~/.local/bin/crcstop ~/.local/bin/crcstart
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

crc-cmd is a skill published in the GitHub repository rhtevan/agentfs (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 15 tokens to every session and 2,540 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
