What is hep-numerics?

A numerical-analysis workflow for high-energy physics, the study of particles and their interactions.

Use it to validate scan settings, run numerical model scans, apply constraints, make exclusion plots, rerun analyses, and create summaries and reproducibility records. It does not change model assumptions or decide whether a model is publishable.

It organizes and checks computational scans so that failed calculations, skipped evaluations, figures, and published results are not confused with one another.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00082	$0.04745
Opus 5	$0.00041	$0.02372
Sonnet 5	$0.00016	$0.00949

Security

Grade A, and why

hep-numerics 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.

The scan reads SKILL.md. This mod also ships 12 executable files (scripts/_custom_observables.py, scripts/_dependency_graph.py, scripts/_identity.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

HEP Numerics

Use this skill as the numeric execution layer for a structured HEP workspace. It routes validated model, calculation, and constraint artifacts into scans, constraint decisions, figures, summaries, and manifest updates.

1. Skill Responsibilities And Boundaries

Responsible: read existing workspace artifacts, validate scan-configs, run numeric scans, evaluate constraints, make figures, write summaries, and update numerics manifest entries.
Responsible: preserve reproducibility through scan.csv, scan.meta.json, deterministic figure names, and manifest history.
Responsible: distinguish hard failures from skipped evaluations and skipped figures without publishing an incomplete scan as a successful result.
Not responsible: inventing physics, changing model assumptions, changing experimental data, or deciding whether a model is publishable.
Not responsible: symbolic derivations, Feynman rules, loop reductions, or Package-X work.
Not responsible: silently editing model/, constraints/, or calculations/ to make a scan pass.
Not responsible: replacing schema, script, or test checks with prose-only judgment.

2. Workspace Inputs And Outputs

Read these workspace inputs when present:

manifest.json
model/model-spec.json
model/calc-tasks.json
constraints/constraints-data.json
calculations/task-*/result-meta.json
calculations/task-*/result-python.py
numerics/scan-configs/{analysis_id}.json
numerics/custom_observables.py

Write only these workspace outputs:

numerics/scan-configs/{analysis_id}.json
numerics/scan-results/{analysis_id}/scan.csv
numerics/scan-results/{analysis_id}/scan.meta.json
numerics/figures/{analysis_id}/*.{pdf,png}
numerics/analysis-summary-{analysis_id}.md
manifest.json numerics artifact entries and allowed history actions

Treat model/, constraints/, and calculations/ inputs as read-only.

3. Mode Classification

Classify the mode before reading or writing numerics outputs.

What ships with it

20 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

hep-numerics is a skill published in the GitHub repository huangzhonglv/hep-workflow (9 stars, last pushed 1mo ago), licensed MIT. It adds 82 tokens to every session and 4,745 once invoked, about $0.0004 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.
