nicar2026_skills_in_codex_claude: Skill for Claude Code

.claude/skills/state-county-rankings/SKILL.md

state-county-rankings is a skill for Claude Code from amkessler/nicar2026_skills_in_codex_claude. It costs 40 tokens per session (397 once invoked), scanned A, original, Apache-2.0.

A tool for ranking counties within a U.S. state using demographic measures from a local CSV file. A CSV is a table-like text file, and county rankings can cover measures such as income, population, poverty, or rent.

In plain words
What is it for?
Use it to select a state and metric, rank its counties, and return each county's value, rank, and ranking direction.
Why use it?
It produces consistent top-to-bottom or bottom-to-top comparisons without needing an online data service.

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.

Fable 5.1 $0.00040 $0.00397

Security

Grade A, and why

state-county-rankings 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 2mo 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.

What it actually says

State County Rankings

Use this skill to rank counties within a state for one or more metrics from a local dataset.

Requirements

  • R with dplyr, tidyr, readr, stringr, and jsonlite
  • Local CSV input with county, a state column (state, state_name, or state_abbrev), and requested metric columns
  • Bundled Census CSV for immediate use: skills/state-county-rankings/data/county_demographics_acs5_2023.csv
  • No API key required

Standard Workflow

  1. Confirm input CSV path and state.
    • --state accepts full names or USPS abbreviations (for example, Georgia or GA).
    • Default bundled input: skills/state-county-rankings/data/county_demographics_acs5_2023.csv
  2. Review skills/state-county-rankings/references/COLUMN_REQUIREMENTS.md and use exact output headers before downstream filtering/selecting.
    • Output columns are state, county, metric, value, rank, and direction.
  3. Ask for metrics (or use defaults) and ranking direction.
  4. Run:
    • Rscript skills/state-county-rankings/scripts/get_state_county_rankings.R --input skills/state-county-rankings/data/county_demographics_acs5_2023.csv --state "<state>"
  5. Return top/bottom county rankings and note missing/invalid fields.

Output

Return ranked rows with:

  • state
  • county
  • metric
  • value
  • rank
  • direction

Changes

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.
