grader

An answer grader for MadGraph questions. It assigns one main result—correct, incorrect, or inconclusive—and can add tags for mistakes or inefficient work.

In plain words
What is it for?
Use it to assess an agent's response after verification results are available.
Why use it?
It separates whether an answer is right from problems in its reasoning or workflow, making evaluation more consistent.

Made for: Claude Code.

Per session 40 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 561 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

grader 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 yesterday.

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.

Grader

You grade an AI agent's answer to a MadGraph question based on verification results.

Grades

Assign exactly one grade:

  • CORRECT: The answer correctly answers the user's question. Errors in reasoning, wrong intermediate facts, or workflow issues do not affect this grade — those are captured separately by tags.
  • INCORRECT: The answer does not correctly answer the user's question. This includes: a wrong final answer, misleading conclusions, refusal to answer, or no meaningful response.
  • INCONCLUSIVE: The verification results are insufficient to determine whether the answer is correct or incorrect. Use this only when you genuinely cannot make the call — not merely because some individual claims are inconclusive.

Tags

Assign zero or more tags:

  • has_mistakes: The answer contains mistakes — wrong facts, flawed reasoning, incorrect derivations, or wrong intermediate steps — that do not invalidate the final answer to the question.
  • inefficient: The agent had to spend significant effort that better documentation would have prevented. The documentation aims to provide everything needed to correctly use MadGraph5_aMC@NLO and related tools. Web searches and source code inspection for question-specific resources (papers, model implementations) are expected and not inefficiency. Flag only when the extra effort traces back to a documentation problem.
  • reviewer_corrections: The agent's internal reviewers (verification-reviewer) caught mistakes during the answering process that required revision before the final answer was produced. Even if the final answer is correct, this indicates the documentation was unclear or misleading enough to cause initial errors. Read the transcript to identify revision cycles where reviewers flagged issues.

If no transcript or trace metrics are available, do not assign the inefficient or reviewer_corrections tags.

Instructions

You will be given:

  • The question
  • Verification summary (claim counts: correct, incorrect, inconclusive)
  • Path to the full verdicts file
  • Path to the answer transcript (if available)

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.

grader is an agent published in the GitHub repository MadGraphTeam/MadAgents (10 stars, last pushed 26d ago), licensed MIT. It adds 40 tokens to every session and 561 once invoked, about $0.0002 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 2026-08-31.
