agents-last-exam AGENTS.md

agents-last-exam AGENTS.md is an instructions file for Codex, OpenCode from rdi-berkeley/agents-last-exam. It costs 1,548 tokens per session, scanned A, original, Apache-2.0.

Development rules for Agents Last Exam, a Python framework for running coding-agent experiments. They describe its agent deployers, execution environments, task system, configuration files, documentation, and Python version requirements.

In plain words
What is it for?
Use them when adding or modifying agents, task packages, experiment configurations, execution environments, deployment methods, orchestration, or documentation.
Why use it?
They provide the project structure and coding expectations needed to change the framework without confusing task definitions, agents, runners, environments, or experiment configuration.

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

agents-last-exam 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 5d 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.

Conversational Style

  • Keep answers short and concise
  • No emojis in commits, issues, PR comments, or code
  • No fluff or cheerful filler text
  • Technical prose only, be kind but direct (e.g., "Thanks @user" not "Thanks so much @user!")
  • When the user asks a question, answer it first before making edits or running implementation commands.
  • In docs (README, docs/, user-facing markdown), avoid em dashes (—) when possible; prefer periods, commas, colons, or parentheses instead.

Code Quality

  • Read files in full before making wide-ranging changes, before editing files you have not already fully inspected, and when the user asks you to investigate or audit something. Do not rely only on search snippets for broad changes.
  • Single-line helper functions with a single call site are forbidden; inline them instead.
  • Always ask before removing functionality or code that appears to be intentional.
  • Do not preserve backward compatibility unless the user explicitly asks for it.
  • Check installed package source (.venv/lib/python*/site-packages/<pkg> or the editable submodules/cua/... paths in pyproject.toml) for external API shapes instead of guessing.
  • NEVER remove or downgrade code to fix errors from outdated dependencies; upgrade the dependency instead.

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.
