Stata-CLI: Instructions file for Codex

AGENTS.md

Stata-CLI AGENTS.md is an instructions file for Codex, OpenCode from Utolaris/Stata-CLI. It costs 559 tokens per session, scanned A, original, MIT.

A project guide for Stata-CLI, a local command-line tool with a Rust engine and an init scaffold for AI-assisted Stata analysis. Stata is software commonly used for statistical data analysis.

In plain words
What is it for?
Use it when working on the Rust CLI, Stata engine, repository-local binaries, reference packages, or files generated by stata-cli init.
Why use it?
It tells agents where the project’s local binaries, reference material, templates, and smoke-test workspace live. This reduces the risk of changing the wrong source files or breaking repository discovery.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code; reads ~/.codex paths.

This is Utolaris/Stata-CLI's own configuration. It tells Codex and OpenCode how to work on Stata-CLI 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 Stata-CLI 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

Stata-CLI 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 1mo 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.

Working Rules

  • Keep the repo-local binaries in skill/stata-cli/bin/; repo-root discovery depends on that location.
  • Treat skill/stata-cli/boilerplate/ as the source of truth for files created by stata-cli init.
  • Treat skill/stata-cli/ itself as the installed skill package: SKILL.md, references/, packages/, and bin/ ship together and are not duplicated into workspaces by init.
  • The stata-cli.skill file attached to GitHub releases is a ZIP archive of skill/stata-cli/ (top-level folder stata-cli/); unpack it and drop that folder into any agent's skills directory (Codex: ~/.codex/skills/, Claude Code: ~/.claude/skills/).
  • When changing CLI behavior or REPL behavior, verify the Rust tests and run real Stata smoke tests from scene/ (set SKIP_STATA_TESTS=1 to skip them).
  • Real smoke tests should run from scene/ and use scene/grilic.dta.
  • The native Stata engine (rust-cli/src/atom/stata_engine.rs) is the only module allowed to use unsafe; it wraps Stata's StataSO_* C ABI behind a safe API. See the module docs and README.md ("Unsafe FFI") before touching it.

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.
