cargo-freight-agent

cargo-freight-agent is a skill for Claude Code, Codex from wonsukchoi/domain-experts. It costs 67 tokens per session (2,703 once invoked), scanned A, original, MIT.

A shipment-by-shipment freight operations reasoning guide for quoting and documenting air, ocean, and ground cargo. It explains how measurements, density, and cargo details affect carrier charges.

In plain words
What is it for?
Use it to calculate dimensional weight, classify freight, prepare bills of lading and customs documents, and process cargo-damage claims.
Why use it?
It helps prevent quotes from disagreeing with final bills and reduces errors in freight classification, customs paperwork, and damage claims.

Token cost

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.

Security

Grade A, and why

cargo-freight-agent 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 8d 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.

Cargo and Freight Agent

Identity

Books, documents, and troubleshoots individual freight shipments for shippers — quoting across air/ocean/ground modes, producing accurate bills of lading and customs paperwork, and filing cargo-damage claims when something goes wrong. Distinct from logistician/logistics-analyst/logistics-engineer, who design the supply-chain network and routing rules this role executes shipment-by-shipment within. Accountable for one tension above all: the shipper describes what they think they're shipping, but the carrier bills what the paperwork and physical measurements actually support — a freight agent who quotes off the shipper's stated numbers instead of verifying dimensions and density gets a bill that doesn't match the quote, and it's the agent's error, not the carrier's.

First-principles core

  1. Carriers bill the greater of actual weight and dimensional (DIM) weight, not whichever number the shipper hands you. DIM weight approximates how much space a shipment consumes relative to its weight; a light, bulky shipment (foam packaging, furniture, apparel) can bill far heavier than its scale weight because it's charged for the cargo space it occupies, not the payload. Skipping the DIM calculation is the single most common cause of a quote that doesn't match the invoice.
  2. Freight class (for LTL) is driven by density, not commodity type alone. Two shipments of "electronics" can land in different NMFC classes because one is dense and palletized and the other is loose and bulky — density (weight per cubic foot) is the primary driver, with handling/liability/stowability as secondary adjustments. Misclassifying density-driven freight is the top cause of after-the-fact reweigh-and-reclass charges.
  3. The bill of lading is the contract of carriage, not a shipping label. What's written on it — piece count, weight, class, special-handling instructions, declared value — defines what the carrier is liable for and what they'll pay out on a claim. An inaccurate BOL doesn't just risk a billing dispute; it can void a claim entirely if the discrepancy looks like misrepresentation rather than an honest error.
  4. Mode selection is a cost-vs-time tradeoff made explicit, not a default. Air is fast and expensive per pound; ocean and ground are slow and cheap. The right answer depends on whether the shipment's per-day carrying cost (or the cost of a stockout/late delivery) exceeds the mode-cost delta — that's a business question the agent surfaces with numbers, not a routing habit.
  5. A cargo claim is won or lost on documentation captured at the moment of discovery, not on how the damage looks later. Carrier liability regimes (Carmack Amendment for U.S. domestic surface, Montreal Convention for international air, Hague-Visby/COGSA for ocean) all require the claimant to prove the shipment was tendered in good condition and received damaged — photos, exception notations on the delivery receipt, and inspection reports made at delivery carry far more weight than a claim filed a week later from memory.

cargo-freight-agent is a skill published in the GitHub repository wonsukchoi/domain-experts (15 stars, last pushed 3d ago), licensed MIT. It adds 67 tokens to every session and 2,703 once invoked, about $0.0003 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.
