criticality-rank

Prioritizes the fault by asset criticality and downtime cost into a P1-P4 maintenance priority with a response target and cost estimate, deterministically. Use when the user says "how urgent is this", "what's the priority", "rank by criticality", "what will downtime cost", or after failure-mode-rank completes.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
6 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by microsoft on GitHub. Read the source before you install it.

Installation

Install the Criticality Rank AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/microsoft/cat-agent-skills/tree/main/submissions/maintenance-triage/skills/criticality-rank
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/microsoft/cat-agent-skills.git /tmp/cat-agent-skills
mkdir -p .claude/skills
cp -r /tmp/cat-agent-skills/submissions/maintenance-triage/skills/criticality-rank .claude/skills/criticality-rank

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Criticality Rank in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Criticality Rank on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Criticality Rank is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Criticality Rank

Purpose

Deterministically compute the maintenance priority (P1-P4), response target, and downtime cost for the fault from the asset-criticality matrix, escalating for recurring failures.

When to use

After failure-mode-rank, in every triage run.
"How urgent is this?" / "what's the priority?" / "what does downtime cost?".

Inputs

The contract payload with ranked_causes[], asset_criticality, downtime_cost_per_hr, and history.repeat_promotion (contract mfg.maintenance-triage.v1, the {ranked_causes} hop).

Steps

Validate the payload against the contract.
Run scripts/criticality_score.py --ranked ranked-causes.json --out triaged.json.
Do not restate or recompute any score in prose; quote the engine output verbatim.
Emit the {priority} contract payload and the recommended_action.

Output

Contract mfg.maintenance-triage.v1 with a populated priority{} object (level, score, response_target, downtime_cost_estimate, factors, confidence, source=engine:criticality_score, citation) — the {priority} hop.

Grounding requirements

Every priority cites the matrix sections used and ISO 55000 risk-based prioritization (references/asset-criticality-matrix.md, references/rcm-iso55000-excerpts.md).

Constraints

All scoring math happens in the engine. The model must never set a priority itself.
Never downgrade a repeat-failure escalation to save a planned-outage slot.
Do not draft the work order here — that is work-order-update's job.

Escalation / uncertainty

Missing downtime cost yields an estimated impact and an escalation; a P1 assignment or a repeat-failure escalation is surfaced to the shift supervisor and planner (asset-criticality-matrix.md #6).

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Criticality Rank AI skill do?

Why use Criticality Rank on TypingMind?

Because you install it once and use it with any model. Criticality Rank is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Criticality Rank in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/microsoft/cat-agent-skills/tree/main/submissions/maintenance-triage/skills/criticality-rank. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Criticality Rank?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Criticality Rank?

As many as you like. As long as a model supports skills, you can use Criticality Rank with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Criticality Rank AI skill free?

Yes. It is published on GitHub by microsoft under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
