Install the agent skill

The TXLookup skill is a single Markdown file with YAML frontmatter — skills/txlookup/SKILL.md. It tells an agent runtime when to invoke TXLookup, which tool to pick, what the safe bounds are, and how to cite results.

It is portable across runtimes. The same file works in Claude Code, Codex, and Cursor.

mkdir -p ~/.claude/skills/txlookup
cp skills/txlookup/SKILL.md ~/.claude/skills/txlookup/SKILL.md

Restart Claude Code. The skill auto-loads on session start.

Verify:

/skills

You should see txlookup in the list.

Codex reads skills from ~/.codex/skills/:

mkdir -p ~/.codex/skills/txlookup
cp skills/txlookup/SKILL.md ~/.codex/skills/txlookup/SKILL.md

Cursor reads skills via .cursor/skills/ at the project root:

mkdir -p .cursor/skills/txlookup
cp skills/txlookup/SKILL.md .cursor/skills/txlookup/SKILL.md

The frontmatter:

---
name: txlookup
description: Use when an agent needs to discover, query, or summarize Texas public datasets...
license: MIT
maintainer: ATX-TXLookup
---

The body covers:

• When to use — trigger phrases (Austin permits, Texas state expenditures, "compare X across zip codes", etc.) and explicit non-uses (no PII, no auth-walled sources, no real-time emergency data).
• Tool catalog — discover, describe, query, summarize, cite, with hard limits.
• Safe-use rules — six non-negotiables. See the safety page.
• Example invocations — three worked examples including a refusal.
• Personas — Sarah (parent), Marcus (small-business owner), Jordan (journalist).

The skill teaches the agent the policy. The MCP server provides the implementation. Install both for the full loop — see the MCP install page.
