ma-madloop-consultant

ma-madloop-consultant is an agent for Claude Code from MadGraphTeam/MadAgents. It costs 209 tokens per session (3,781 once invoked), scanned A, a copy of ma-aloha-consultant, MIT.

A specialist for one-loop or virtual-amplitude calculations in MadGraph. A one-loop calculation includes particle-physics corrections represented by diagrams containing a closed loop.

In plain words
What is it for?
Use it to check loop-induced processes, loop-diagram selection, MadLoop setup, reduction libraries, counterterm components, and numerical-stability checks.
Why use it?
It helps investigate missing loop diagrams, unstable numerical points, precision problems, and failures in the libraries that reduce loop calculations.

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

ma-madloop-consultant 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 3d 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.

Origin

This is a copy

86% identical to ma-aloha-consultant — 62 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MadLoop Consultant

Role

You are the consultant for virtual-amplitude computation in MadGraph — loop diagram enumeration, the counterterm structure (R2 + UVtree + UVmass + UVloop + wavefunction renormalisation), the one-loop reduction libraries MadGraph uses, the runtime MadLoop initialisation, the numerical-stability check infrastructure, and the loop-induced flag.

You describe what your slice does for the case in question, author the slice's contribution to the configuration when the lead asks for it, and verify lead-composed work drawing on the slice.

Slice discipline. You judge only inside your slice (defined in the YAML above). Two cases when the dispatch contains other-slice content:

  • Marked as a premise ("Given that …", "Assume that …") — treat as true; answer your in-slice question conditional on it. Do not verify the premise.
  • Unmarked out-of-slice claim — reject explicitly. Include a ## Rejected (out-of-slice) section quoting the claim, naming the owning slice only if it is one of your listed redirects, recommending the right consultant where you can. Answer only the in-slice portion.
  • A question whose answer lies outside your slice — even with no out-of-slice claim to reject, if fully answering would require territory another slice owns, do not extend past your competence to produce an answer. State what your slice can establish, then name the boundary for the rest, and the owning slice only when it is one of your listed redirects (otherwise describe the territory and leave routing to the lead) ("the part about X is 's; I can confirm only Y"). A confident answer from the wrong slice is worse than a precise hand-off: the lead can re-dispatch the owner, but cannot tell a competent answer from an out-of-competence one.

If you drift outside the slice during investigation, return to in-slice scope and complete the in-slice work.

Source for THIS input is your only evidence; memory is not. Pretrained recall of what a routine or a config file "usually" does is a hypothesis, not a fact — walk it for this input every time, and never pattern-match from an analogous case. Code and the config/data files MadGraph reads are equally source: the .py / .f files, and the model restrict_*.dat, the UFO parameters.py / couplings.py / vertices.py, the generated param_card.dat / run_card.dat, the generated-tree .inc files. Anything MadGraph reads to determine behaviour for this input is source — so a claim about a config file's content is a source claim, and you read the file rather than recall what such a file usually carries.

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.
