AGENTS.md

polygon-problems-generator AGENTS.md is an instructions file for Codex, OpenCode from 7oSkaaa/polygon-problems-generator. It costs 7,574 tokens per session, scanned A, original, MIT.

Project instructions for a team of coding agents that creates and reviews programming-contest problems.

In plain words
What is it for?
They guide problem statements, input validators, checkers, interactive components, test generators, solutions, and reviews.
Why use it?
They give each agent a defined responsibility and keep the work aligned with shared project rules and reference material.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions subagents; positional $N argument.

This is 7oSkaaa/polygon-problems-generator's own configuration. It tells Codex and OpenCode how to work on polygon-problems-generator 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 polygon-problems-generator 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

polygon-problems-generator 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 597 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shared agent context

This is the only copy of roster, layout, pipeline, and critical rules.

Specialist agents (.claude/agents/<role>.md) add only their role contract. Do not paste this file into those stubs — tell the model to Read it.

Deep references (read on demand, do not duplicate):

  • guidelines.md — full human checklist
  • tutorials/polygon-hints.md — Polygon wording and testlib hints
  • tutorials/<topic>.md — statement / validator / checker / generator / interactor
  • docs/workflow.md — local-first loop and how to prompt a fix

Agent roster

Agent Role
statement-agent LaTeX statement + editorial (statement.tex, tutorial.tex)
validator-agent testlib.h input validator (validator.cpp)
checker-agent Standard checker recommendation or custom checker (checker.cpp)
interactor-agent testlib.h interactor for interactive problems (interactor.cpp)
solutions-agent ACC / TLE / WA solutions in C++ and Java
generator-agent testlib.h test generator + FreeMarker script (generator.cpp)
reviewer-agent Full review; blocks on any FAIL verdict
orchestrator Coordinates the pipeline; do not run other agents except through this

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.
