How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file

We split this skill into the rules it gives an agent

3 rules. 0 are common, 3 are distinctive, and 0 are very specific to this project.

0
Common
Most of the 4 edited versions we read keep these.
3
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

Common
Distinctive
Very specific

Distinctive:
Use for spend, anomalies, and AKS or AI allocation.
line 23
Distinctive:
Use cost tools and Resource Graph first.
line 27
Distinctive:
Never transform MCP results in a shell or interpreter.
line 34

“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Azure Cost Analysis

Quick Reference

Intent	Workflow	Primary tools
Query historical spend	Cost query	`query_costs`
Explain a spike	Cost investigation	`query_costs`, Resource Graph
Analyze AKS spend	AKS cost analysis	`query_aks_costs`, Resource Graph
Analyze AI service spend	AI cost analysis	`query_costs`

When to Use This Skill

Use for spend, anomalies, and AKS or AI allocation.

MCP Tools

Use cost tools and Resource Graph first. If an operation is unavailable, follow fallback and safety.

Workflow

Confirm scope, period, currency, and breakdown.
Load only the matching workflow above.
Never transform MCP results in a shell or interpreter; request tool-side totals, grouping, sorting, or bounded follow-up queries.
Respect row limits and label incomplete data.
Separate measured cost from inferred causes and recommendations.

Error Handling

Error	Action
Access denied	Name the required scope and role.
Empty result	Distinguish no data from unavailable data.
Multiple currencies	Report each currency separately.
Server error	Retry once; then stop with the trace ID.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

It worked
Partly
It didn't

What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
