“Calculates real-time price arbitrage across multi-provider spot inference endpoints under strict latency SLOs.”

 [Undominated.ai · upstream description ↗](https://undominated.ai/resources/skills/undominated-dynamic-spot-rate-arbitrage-audit/definition.md) Our analysis follows below.

01 / THE REASONING

## Why this made the selection.

 - Pairs a bounded workflow with an offline Python checker and explicitly synthetic example inputs.
- Created for recurring evidence and comparison failures: missing facts remain unknown and every conclusion keeps its scope.
- It names a concrete failure mode: Calculates real-time price arbitrage across multi-provider spot inference endpoints under strict latency SLOs.

### A good fit for

 - Audit dynamic routing proxies that arbitrage inference requests across competitive provider rate cards.
- Run the local checker against a supplied file for this stated condition: FAILED: Arbitrage savings {save_rounded}% below {min_s}%.

### Weigh up before choosing

 - Evaluates observed rate cards and achieved dollar savings.
- Fixture checks establish the documented local behaviour, not performance on an unrestricted set of real tasks.
- Public GitHub source availability is not yet verified; the complete download contains the reviewed source.
- A new npm install path is not yet verified. Use the complete source download.
- `2`: Schema error or invalid usage.

02 / THE REVIEW RECORD

## What we actually inspected.

Source review has boundaries. A clear record is more useful than a “safe” badge.

### Material inspected

 - skills/undominated-dynamic-spot-rate-arbitrage-audit/SKILL.md
- skills/undominated-dynamic-spot-rate-arbitrage-audit/scripts/check.py
- skills/undominated-dynamic-spot-rate-arbitrage-audit/examples/synthetic.json

### Our findings

 - First-party resource authored by Undominated.ai; this is our own verification record, not an independent endorsement.
- The download preserves the complete source and supporting files. Its manifest hashes identify the exact bytes.
- The checker names its required fields as: req = ["baseline_cost_usd", "arbitraged_cost_usd", "min_saving_percent"].
- The checker rejects the run rather than passing: FAILED: Arbitrage savings {save_rounded}% below {min_s}%.

### Not established by this review

 - Model compliance with these instructions on arbitrary tasks
- Native integration in every agent host
- Public GitHub source identity
- Remote installation through the standard Skills CLI
- The new npm resource CLI installation

The review applies to the material and revision named here. A newer upstream release can change its behavior.

03 / PUT IT TO WORK

## Add a skill to your workflow.

[Upstream setup instructions ↗](https://undominated.ai/resources/skills/undominated-dynamic-spot-rate-arbitrage-audit/definition.md)
 - Download the complete bundle from https://undominated.ai/resources/skills/undominated-dynamic-spot-rate-arbitrage-audit/bundle.zip and extract it into a new directory.
- Place the extracted directory at .agents/skills/undominated-dynamic-spot-rate-arbitrage-audit/ or your host's documented skills directory. Preserve SKILL.md, scripts, examples and licence files together.
- Run the documented synthetic example from the skill directory with Python 3.10 or later before using your own evidence.

### Before you start

 - An Agent Skills compatible host
- Python 3.10 or later for the optional checker

### Compatibility

Agent Skills compatible hosts · Python 3.10+

### Implementation

Python · Markdown

### Local, explicit inputs

 - read:user-selected-local-file

### Cost model

MIT source at no charge. Your agent host or model provider may charge for use; the included offline checks require no paid API.

 # Dynamic Spot Rate Arbitrage Audit

## Description
Calculates real-time price arbitrage across multi-provider spot inference endpoints under strict latency SLOs.

## Category
`evaluation`

## Tags
`spot-arbitrage`, `routing`, `pricing`, `cost-savings`

## When to Use
Audit dynamic routing proxies that arbitrage inference requests across competitive provider rate cards.

## Operational Limitations
Evaluates observed rate cards and achieved dollar savings.

## Verification Script
Run the deterministic verification checker:
```bash
python3 scripts/check.py examples/synthetic.json
```
Exit codes:
- `0`: Check passed and thresholds satisfied.
- `1`: Threshold breach or operational violation detected.
- `2`: Schema error or invalid usage.

The download contains SKILL.md . Extract the whole bundle; the supporting files are required. Inspect the included MANIFEST.json for file hashes.
