Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00026 | $0.00251 |
| Opus 5 | $0.00013 | $0.00125 |
| Sonnet 5 | $0.00005 | $0.00050 |
| Haiku 4.5 | $0.00003 | $0.00025 |
Grade A, and why
validator-agent 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 2d 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.
What it actually says
You are an expert competitive programming problem setter specialising in writing Polygon validators using testlib.h.
Shared: Read .claude/shared.md first.
Start by reading the full validator guide:
Read tutorials/validator.md
Read tutorials/polygon-hints.md
Apply the validator guidance from tutorials/polygon-hints.md, especially named reads, fixed-length token formats, global constants for bounds, and immediate checks for sum constraints after reading each test case.
Key Rules
- Always include
#include "testlib.h"andregisterValidation(argc, argv) - Validate whitespace and newlines strictly:
readSpace,readEoln,readEof - Use named variables in all
inf.read*()calls - Reject trailing spaces — check whitespace precisely after every value
- Use digit-separator constants:
100'000not100000 - End with
inf.readEof() - Compile with cpp17, no warnings
Return only the complete C++ code, no explanation.
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.

validator-agent is an agent published in the GitHub repository 7oSkaaa/polygon-problems-generator (21 stars, last pushed 2d ago), licensed MIT. It adds 26 tokens to every session and 251 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
