country-usa

country-usa is a skill for Claude Code from Abhinavbwj/Skills-Architects. It costs 352 tokens per session (7,526 once invoked), scanned A, original, MIT.

A reference for United States building and fire codes used in architectural projects. It explains model codes, such as the IBC and IRC, and how states, cities, or other local authorities adopt and amend them.

In plain words
What is it for?
Checking requirements for building, residential, fire, energy, mechanical, plumbing, fuel-gas, existing-building, accessibility, and structural-code work in US jurisdictions.
Why use it?
It helps clarify which rules apply because the United States has no single federally enforced building code.

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

country-usa 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 13d 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.

Country: United States of America

Architectural code and regulatory reference for projects within any US state, territory, or D.C. Activate this skill on any US city/state reference, USD currency, square feet / imperial units, mention of "IBC"/"IRC"/"IECC"/"NFPA"/"ASCE 7"/"ADA"/"Title 24"/"CalGreen"/"NYC BC", state building department/AHJ references, or LEED/ENERGY STAR.


1. Regulatory Hierarchy

The US operates as Archetype B (National Model + State/Local Adoption) with significant local variation. There is no federal building code; the Authority Having Jurisdiction (AHJ) -- which may be the city, county, state, or special district -- decides which model code edition is in force and with what amendments.

1.1 Authority Stack

LEVEL 1 -- MODEL CODE PUBLISHERS (no enforcement authority)
  International Code Council (ICC) -- IBC, IRC, IECC, IFC, IPC, IMC, IFGC, IEBC, IgCC, IWUIC
  National Fire Protection Association (NFPA) -- NFPA 101, 70, 13, 72, 285, 5000
  ASHRAE -- 90.1, 62.1, 55, 169, 189.1
  ASCE -- 7, 41
  ACI -- 318, 530, etc.
  AISC -- 360, 341, 358, 360
  AWS -- D1.1, D1.5
  AWC -- NDS, SDPWS
  TMS -- 402/602 masonry
  ANSI -- A117.1 accessibility, others
  ASTM -- material/test standards

LEVEL 2 -- FEDERAL APPLICABILITY (specific contexts)
  ADA 2010 Standards (Department of Justice) -- enforcement civil rights
  ABA Standards (GSA) -- federal facilities + recipients of federal funds
  Fair Housing Act design + construction (HUD) -- residential
  HUD Section 504 -- recipients of HUD funds
  IRS Energy Tax Credit (179D, 45L) -- referenced ASHRAE 90.1
  GSA P100 -- federal facilities standard
  DOD UFC -- military facilities
  NPS -- National Park Service properties

LEVEL 3 -- STATE
  State Building Code Council / DOR / Construction Department adopts model code edition
    + state amendments (e.g., California Building Standards Commission - Title 24)
  State Energy Office -- often state energy code (e.g., WA Energy Code)
  State Fire Marshal -- often state fire code
  State Architectural Access Board (e.g., Massachusetts MAAB)
  State Department of Health -- hospital codes (FGI Guidelines often adopted)
  State Department of Education -- school facility codes (CHPS, varies)

LEVEL 4 -- LOCAL AHJ
  City/County Building Department (Department of Buildings NYC, LADBS LA, etc.)
    + adopted code + local amendments
  Fire Marshal
  Public Works (right-of-way, utility connections)
  Planning Department (zoning, design review)
  Historic Preservation Commission (HPC) -- if in historic district

LEVEL 5 -- SPECIAL DISTRICTS
  School districts (own facility standards)
  Transit authorities (own design criteria)
  Universities/medical centers (often own building standards)
  Master-planned communities (HOA design review)
  Tribal authorities (sovereign on reservation land)

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.
