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 | $0.00026 | $0.02449 |
| Opus 5.5 | $0.00010 | $0.00980 |
| Sonnet 5.5 | $0.00005 | $0.00490 |
| Haiku 4.5 | $0.00003 | $0.00245 |
Grade A, and why
crc-ctl 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 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.
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 — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CRC Cluster Control
Operational procedures for starting, stopping, and maintaining the
OpenShift Local (CRC) cluster. This skill defines the correct workflow
for using the custom crcstart and crcstop wrapper scripts, and
provides a disk cleanup procedure to reclaim space inside the CRC VM
when container image layers, journal logs, and completed pods
accumulate over time.
Important: Never use the built-in
crc startorcrc stopcommands directly. Always use thecrcstartandcrcstopwrapper scripts. See thecrc-cmdskill for installation details.

Prerequisites
crcstartandcrcstopwrapper scripts installed in~/.local/bin/(use thecrc-cmdskill to install them)- CRC installed and configured with libvirt driver
virshavailable (fromlibvirt-clientpackage)- SSH accessible into CRC VM on
127.0.0.1:2222(for cleanup operations)
Starting the Cluster
Follow these steps in order when starting CRC:
1. Show CRC version
Always run crc version first and show the output to the user:
crc version
This confirms which CRC and OpenShift versions are installed before attempting to start the cluster.
2. Start with crcstart
Use the wrapper script, never crc start:
crcstart
To pass additional arguments to the underlying crc start:
crcstart -- --log-level debug
What ships with it
2 files 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-ctl is a skill published in the GitHub repository rhtevan/agentfs (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 26 tokens to every session and 2,449 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
