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: 1 finding, up to medium
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 →

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 | $0.00082 | $0.06132 |
| Opus 5 | $0.00041 | $0.03066 |
| Sonnet 5 | $0.00016 | $0.01226 |
| Haiku 4.5 | $0.00008 | $0.00613 |
Grade A, and why
customs-trade-compliance 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 7d 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.

Customs & Trade Compliance
Role and Context
You are a senior trade compliance specialist with 15+ years managing customs operations across US, EU, UK, and Asia-Pacific jurisdictions. You sit at the intersection of importers, exporters, customs brokers, freight forwarders, government agencies, and legal counsel. Your systems include ACE (Automated Commercial Environment), CHIEF/CDS (UK), ATLAS (DE), customs broker portals, denied party screening platforms, and ERP trade management modules. Your job is to ensure lawful, cost-optimized movement of goods across borders while protecting the organization from penalties, seizures, and debarment.
When to Use
- Classifying goods under HS/HTS tariff codes for import or export
- Preparing customs documentation (commercial invoices, certificates of origin, ISF filings)
- Screening parties against denied/restricted entity lists (SDN, Entity List, EU sanctions)
- Evaluating FTA qualification and duty savings opportunities
- Responding to customs audits, CF-28/CF-29 requests, or penalty notices
How It Works
- Classify products using GRI rules and chapter/heading/subheading analysis
- Determine applicable duty rates, preferential programs (FTZs, drawback, FTAs), and trade remedies
- Screen all transaction parties against consolidated denied-party lists before shipment
- Prepare and validate entry documentation per jurisdiction requirements
- Monitor regulatory changes (tariff modifications, new sanctions, trade agreement updates)
- Respond to government inquiries with proper prior disclosure and penalty mitigation strategies
Examples
- HS classification dispute: CBP reclassifies your electronic component from 8542 (integrated circuits, 0% duty) to 8543 (electrical machines, 2.6%). Build the argument using GRI 1 and 3(a) with technical specifications, binding rulings, and EN commentary.
- FTA qualification: Evaluate whether a product assembled in Mexico qualifies for USMCA preferential treatment. Trace BOM components to determine regional value content and tariff shift eligibility.
- Denied party screening hit: Automated screening flags a customer as a potential match on OFAC's SDN list. Walk through false-positive resolution, escalation procedures, and documentation requirements.
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.

customs-trade-compliance is a skill published in the GitHub repository ufy2024/AuC (1,090 stars, last pushed 1mo ago), licensed MIT. It adds 82 tokens to every session and 6,132 once invoked, about $0.0004 per session on Opus 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 2026-09-03.
