AuC is a Python framework for running a single AI agent with an asynchronous, pluggable reasoning loop, language-model adapters, permission levels, and observable events. It is used to build coding and conversational agents with tools, security checks, web interfaces, background jobs, evaluations, and isolated execution. The catalogue entries are skills for extending its agent workflow.
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.

SkillSpector: 13 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 78 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- high Tool Misuse · line 138 Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
- medium Agent Snooping · line 21 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.02510 |
| Opus 5 | $0.00020 | $0.01255 |
| Sonnet 5 | $0.00008 | $0.00502 |
| Haiku 4.5 | $0.00004 | $0.00251 |
Grade B, and why
homelab-pihole-dns scanned grade B 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 9d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Homelab Pi-hole DNS
Pi-hole is a network-wide DNS ad blocker that runs on a Raspberry Pi or any Linux host. Every device on your network gets ad and malware domain blocking automatically — no browser extension needed.
When to Use
- Installing Pi-hole on a Raspberry Pi or Linux host
- Configuring Pi-hole as the DNS server for a home network
- Adding or managing blocklists
- Setting up DNS-over-HTTPS (DoH) upstream resolvers
- Creating local DNS records (e.g.
nas.home.lan,pi.home.lan) - Troubleshooting devices that lose internet access after Pi-hole is installed
- Running Pi-hole alongside or instead of DHCP
How Pi-hole Works
Normal flow (without Pi-hole):
Device → requests ads.tracker.com → ISP DNS → real IP → ads load
With Pi-hole:
Device → requests ads.tracker.com → Pi-hole DNS → blocked (returns 0.0.0.0) → no ad
All DNS queries go through Pi-hole first.
Pi-hole checks against blocklists.
Blocked domains return a null response — the ad/tracker never loads.
Allowed domains get forwarded to your upstream resolver (Cloudflare, Google, etc.).
Installation
Docker (Recommended)
Docker is the easiest way to install Pi-hole and makes updates and backups straightforward.
# docker-compose.yml
services:
pihole:
image: pihole/pihole:<pinned-release-tag>
container_name: pihole
ports:
- "53:53/tcp"
- "53:53/udp"
- "80:80/tcp" # Web admin
environment:
TZ: "America/New_York"
WEBPASSWORD: "${PIHOLE_WEBPASSWORD}" # set via .env file or secret
PIHOLE_DNS_: "1.1.1.1;1.0.0.1"
DNSMASQ_LISTENING: "all"
volumes:
- "./etc-pihole:/etc/pihole"
- "./etc-dnsmasq.d:/etc/dnsmasq.d"
restart: unless-stopped
cap_add:
- NET_ADMIN # only needed if Pi-hole will serve DHCP
Replace <pinned-release-tag> with a current Pi-hole release tag before deploying.
Avoid latest for long-lived DNS infrastructure so upgrades are deliberate and
reviewable.
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.

homelab-pihole-dns is a skill published in the GitHub repository ufy2024/AuC (1,090 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 2,510 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
