g5k-kickstart: Instructions file for Codex

AGENTS.md

g5k-kickstart AGENTS.md is an instructions file for Codex, OpenCode from 0nyr/g5k-kickstart. It costs 535 tokens per session, scanned A, original, MIT.

Repository instructions for agents working on 0nyr/g5k-kickstart, a kit for running experiments on the Grid’5000 research testbed. They explain the project layout, operating rules, and conventions.

In plain words
What is it for?
Use them when reserving, launching, monitoring, synchronizing, or cleaning up Grid’5000 experiments, or when following the repository’s dry-run, smoke-run, and full-run approach.
Why use it?
They tell an agent where the operational guidance, documentation, and example experiment are located before it changes or runs anything.

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

This is 0nyr/g5k-kickstart's own configuration. It tells Codex and OpenCode how to work on g5k-kickstart 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 g5k-kickstart 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

g5k-kickstart 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 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.

AGENTS.md — g5k-kickstart

Instructions for AI coding agents (Claude Code, Codex, ...) working in or from this repository.

What this repository is

A kickstart kit for running experiment campaigns on the Grid'5000 testbed. It packages the operational knowledge as an agent skill, human documentation, and a runnable example experiment.

Where to look

  • skills/g5k/SKILL.md is the operational core: golden rules, agent operating modes, OAR cheatsheet, non-interactive SSH patterns, distributed-run methodology, cleanup protocol. If you are about to touch Grid'5000 in any way (reserve, launch, monitor, sync, clean), read it first and follow it.
  • docs/ holds the longer human-readable guides (getting started, usage policy, running experiments, storage and sync, MAMUT-routing worked example).
  • example/ is a fully runnable toy experiment demonstrating the dry-run, smoke-run, full-run methodology with GNU parallel, locally and on g5k.

Claude Code users should install this repo as a plugin (see README.md), which exposes the skill as /g5k-kickstart:g5k. Agents without plugin support can simply read skills/g5k/SKILL.md.

Hard rules for agents operating Grid'5000

These are restated here because they are the ones that protect the account:

  1. Never run compute on a frontend. Experiments only run inside OAR jobs.
  2. Never install or launch an AI agent, LLM runtime, or IDE server on a g5k frontend or node. Agents drive g5k remotely over SSH from the user's machine.
  3. Respect the day/night usage policy: weekday jobs must not cross the 9:00 and 19:00 boundaries (exceptions in the skill), campaigns go to nights and weekends.
  4. Release idle reservations, report every oarsub you place to the user, and clean the remote home after each campaign (sync back, verify, delete).
  5. Fill in or ask for the user configuration (login, project, site, cluster) before issuing any g5k command.

Conventions in this repository

  • Prose in Markdown files is written one paragraph per physical line (editor soft-wrap), never hard-wrapped to a column width.
  • Commands in docs use <login>, <site>, <cluster>, <JOB_ID> placeholders; keep them generic, personal values do not belong in this repo.

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.
