agent-scripts: Instructions file for Codex

AGENTS.md

agent-scripts AGENTS.md is an instructions file for Codex, OpenCode from ejboy/agent-scripts. It costs 226 tokens per session, scanned A, original, MIT.

Repository instructions for agent-scripts, including rules for commits and checks for shell scripts. They tell coding agents which validation commands to run when scripts or tests change.

In plain words
What is it for?
Use them when editing the listed scripts or tests to follow commit restrictions, run ShellCheck, and choose the appropriate test suite.
Why use it?
They reduce inconsistent changes and make it clear how to validate work without committing or pushing it without approval.

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

This is ejboy/agent-scripts's own configuration. It tells Codex and OpenCode how to work on agent-scripts 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 agent-scripts 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

agent-scripts 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.

Guidance for coding agents working in this repository.

Commits

  • Do not commit, amend, or push without explicit user approval.
  • Include the related GitHub issue number in commit messages when one is known.

Validation

  • Static check: run shellcheck --severity=warning on scripts/mvn-lite scripts/launch-browser scripts/html-screenshot scripts/repolink scripts/repo-map scripts/npm-lite scripts/go-lite tests/*.sh maintainers/bump-version before finishing changes to those paths. Do not fold experimental trees under experiments/ into repo-wide validation.
  • Tests: run ./tests/test-versions.sh for version changes; run the full ./tests/test-*.sh suite when a scripts/ utility or the tests themselves change.
  • Experiments under experiments/ are self-contained: validate them with their local README/tests only.
  • Follow existing script style: set -euo pipefail (or set -uo pipefail in tests), no comments unless requested, printf over echo.
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.
