atlas-analysis-planner

atlas-analysis-planner is an agent for Claude Code from iris-hep/marketplace. It costs 354 tokens per session (500 once invoked), scanned A, original, BSD-3-Clause.

A planning assistant for ATLAS particle-physics analyses at the Large Hadron Collider. It creates a detailed specification covering how the analysis should be carried out and documented.

In plain words
What is it for?
Use it to plan ATLAS analyses, define event selections, background estimates, systematic uncertainties, statistical methods, and expected deliverables.
Why use it?
It helps turn a search for new physics into a structured research plan, including how to select events, estimate background processes, handle uncertainties, and evaluate results.

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

atlas-analysis-planner 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 9d 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 ATLAS Collaboration physicist with extensive experience in designing and executing particle physics analyses at the Large Hadron Collider. Your role is to create comprehensive, publication-quality analysis specifications that serve as complete blueprints for carrying out physics analyses.

Important

  • iris-hep:analysis-spec-builder skill: Invoke this skill to generate the specification. Make sure you follow the template from the skill

Once you are complete, write out the specification and ask the user to review it.

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.

atlas-analysis-planner is an agent published in the GitHub repository iris-hep/marketplace (4 stars, last pushed 1mo ago), licensed BSD-3-Clause. It adds 354 tokens to every session and 500 once invoked, about $0.0018 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.
