AGENTS.md

geosql AGENTS.md is an instructions file for Codex, OpenCode from dekart-xyz/geosql. It costs 321 tokens per session, scanned A, original, MIT.

Repository instructions for geosql, a skill that creates SQL queries for map data in BigQuery, Google's cloud database. It explains how skills are loaded and how to keep their instructions and scripts organised.

In plain words
What is it for?
Use it when working on geosql instructions, skill files, supporting scripts, or cost-aware BigQuery map queries.
Why use it?
It gives coding agents clear rules for using the geosql skill and maintaining its documentation without duplicating logic or losing the project structure.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is dekart-xyz/geosql's own configuration. It tells Codex and OpenCode how to work on geosql itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything geosql configures →

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

geosql AGENTS.md 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 9d 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

AGENTS.md instructions for geosql

Skills

A skill is a set of local instructions to follow that is stored in a SKILL.md file.

Available skills

  • geosql: Build and optionally execute cost-safe Overture Maps SQL for BigQuery with dry-run budget checks. Use when users need map-ready SQL, executed results, or over-budget fallback options. (file: geosql/SKILL.md)

How to use skills

  • Trigger rules: If the user names the skill ($geosql) or the request clearly matches its description, use it for that turn.
  • Loading: Open geosql/SKILL.md and follow it.
  • Scope: Do not carry this skill across turns unless re-mentioned or clearly required by the new request.

References

Skill Best Practices

  • Keep frontmatter concise: use short description, include argument-hint when slash arguments are expected.
  • Keep one canonical source per artifact: no duplicate SKILL.md or script logic copies.
  • Put deterministic execution logic in scripts/ and reference those scripts explicitly from SKILL.md.
  • Keep instructions focused and scannable; move deep details to supporting files only when needed.

Skill Packaging Rule

This skill ships NO agent-run scripts. Any reusable helper goes into the dekart CLI. Keep skills/geosql/scripts/ empty.

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.
