refining

refining is a skill for Claude Code, Codex from kucherenko/petropowers. It costs 13 tokens per session (2,763 once invoked), scanned A, original, MIT.

A guide for refinery operations and process improvement, covering crude blending, plant conditions, product quality, and energy use.

In plain words
What is it for?
Use it for crude selection and blending, monitoring and adjusting units, optimizing distillation cut points, troubleshooting, and checking product quality.
Why use it?
It helps engineers and operators reason about refinery decisions using process, laboratory, and control-system data.

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

refining 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 5d 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.

Skill: Refining Pipeline

Guide AI agents through refinery operations and process optimization.

Purpose

Support process and chemical engineers in refinery operations, optimization, and product quality control.

Roles

  • Process Engineer - Unit operations, optimization, troubleshooting
  • Chemical Engineer - Reaction engineering, catalysts, chemistry
  • Plant Operator - Daily operations, monitoring, adjustments
  • Lab Technician - Product quality testing, sampling

Data Types

Data Source Frequency
Crude assay Lab/Supplier Batch
Temperature/pressure DCS Real-time (1-sec)
Flow rates DCS Real-time (1-sec)
Product qualities Lab 4-8 hours
Catalyst activity Lab Weekly
Energy consumption Meters Hourly

Workflow

Phase 1: Crude Selection & Blending

  1. Receive crude assays (composition, properties)
  2. Optimize crude blend for:
    • Target product slate
    • Unit constraints
    • Margin maximization
  3. Plan crude deliveries
  4. Monitor crude tank quality

Phase 2: Process Operations

  1. Monitor unit operations (DCS)
  2. Optimize cut points (distillation)
  3. Adjust operating conditions
  4. Monitor yields and quality
  5. Troubleshoot upsets

Phase 3: Product Quality

  1. Sample products (gasoline, diesel, jet, fuel oil)
  2. Test in lab (ASTM methods)
  3. Blend components to meet specs
  4. Certify products for release
  5. Track product inventory

Phase 4: Energy & Yield Optimization

  1. Monitor energy consumption
  2. Optimize heat integration
  3. Maximize yield of high-value products
  4. Minimize fuel gas, steam consumption
  5. Reduce CO2 emissions

Domain Tasks

These tasks are handled by this skill:

  • Crude oil assay analysis
  • Distillation optimization
  • Product blending calculations
  • Energy balance analysis
  • Yield accounting

Software Tasks

These tasks invoke petropowers:oil-gas-delegation:

  • Process monitoring dashboard
  • Laboratory information system (LIMS)
  • Blending optimization tool
  • Production accounting system

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.

refining is a skill published in the GitHub repository kucherenko/petropowers (11 stars, last pushed 5mo ago), licensed MIT. It adds 13 tokens to every session and 2,763 once invoked, about $0.0001 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 2026-08-30.
