post-processing

post-processing is a skill for Claude Code from beita6969/ScienceClaw. It costs 45 tokens per session (2,072 once invoked), scanned A, original, MIT.

A set of tools for turning raw simulation output into analyzed data, charts, comparisons, and reports. It can work with formats such as JSON, CSV, HDF5, and VTK.

In plain words
What is it for?
Use it for field extraction, time-series analysis, line profiles, statistical summaries, derived quantities such as gradients or fluxes, reference comparisons, and automated reports.
Why use it?
It removes the manual work of extracting fields, tracking changes over time, calculating derived values, and comparing 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

post-processing 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.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/comparison_tool.py, scripts/derived_quantities.py, scripts/field_extractor.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.

Post-Processing Skill

Analyze and extract meaningful information from simulation output data.

Goal

Transform raw simulation output into actionable insights through field extraction, statistical analysis, derived quantities, visualizations, and comparison with reference data.

Inputs to Gather

Before running post-processing scripts, collect:

  1. Output Data Location

    • Path to simulation output files (JSON, CSV, HDF5, VTK)
    • Time step/snapshot indices of interest
    • Field names to extract
  2. Analysis Type

    • Field extraction (spatial data at specific times)
    • Time series (temporal evolution of quantities)
    • Line profiles (1D cuts through domain)
    • Statistical summary (mean, std, distributions)
    • Derived quantities (gradients, integrals, fluxes)
    • Comparison to reference data
  3. Output Requirements

    • Output format (JSON, CSV, tabular)
    • Visualization needs
    • Report format

Scripts

Script Purpose Key Inputs
field_extractor.py Extract field data from output files --input, --field, --timestep
time_series_analyzer.py Analyze temporal evolution --input, --quantity, --window
profile_extractor.py Extract line profiles --input, --field, --start, --end
statistical_analyzer.py Compute field statistics --input, --field, --region
derived_quantities.py Calculate derived quantities --input, --quantity, --params
comparison_tool.py Compare to reference data --simulation, --reference, --metric
report_generator.py Generate summary reports --input, --template, --output

Workflow

1. Data Inventory

First, understand what data is available:

# List available fields and timesteps
python scripts/field_extractor.py --input results/ --list --json

2. Field Extraction

Extract spatial field data at specific timesteps:

# Extract concentration field at timestep 100
python scripts/field_extractor.py \
    --input results/field_0100.json \
    --field concentration \
    --json

# Extract multiple fields
python scripts/field_extractor.py \
    --input results/field_0100.json \
    --field "phi,concentration,temperature" \
    --json

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.

post-processing is a skill published in the GitHub repository beita6969/ScienceClaw (898 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 2,072 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 2026-09-03.
