GPU rental prices

get_gpu_prices

Read-onlyIdempotent

Today's GPU rental prices: the price index in USD per GPU-hour for each GPU (H100, H200, A100, B200, B300, RTX PRO 6000, L40S, RTX A6000, RTX 6000 Ada, L40, RTX 5090, RTX 4090), with 1-day, 1-week and 1-month changes, the index day and a link to each GPU's page. Give one GPU to also get what its page shows: its benchmark contract, each provider's average price standardized to that contract, the posted prices of providers outside the index (AWS, Azure, Google Cloud, Oracle, Koyeb, Packet: each one's lowest, as posted) and its compute futures prices: each exchange listing a contract on its rental price, with the last price and 24-hour volume, refreshed every minute (all of them: https://computescreener.com/futures). For past values use get_price_history; for providers' posted prices get_provider_prices. For questions like "what does an H100 cost per hour?", "how much is it to rent a B200?" or "H200 cloud pricing today".

A4.7/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover safety (readOnly, idempotent, non-destructive), but the description adds substantial behavior: omitting gpu returns all listed GPUs, passing one GPU additionally returns benchmark contract, per-provider standardized averages, out-of-index posted prices and compute futures with last price/24h volume refreshed every minute. This conditional response shape is exactly the kind of detail annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core purpose and the sibling routing are front-loaded, which is good, but the text is one dense run-on sentence that re-lists all 12 enum values already in the schema and embeds a literal URL. The GPU-name recital and futures URL are redundant against structured fields and dilute the sentence.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists so return values need not be re-explained, yet the description still tells the agent enough about the payload shape to choose correctly between the all-GPU and single-GPU modes. Nothing an agent needs to invoke this correctly — optionality, enum scope, alternatives — is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the enum is already documented, so the baseline is 3. The description earns extra credit by explaining the semantic consequence of the parameter: omitting it yields the full index, while supplying one GPU unlocks a richer per-GPU detail block — meaning the schema does not carry.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific resource and scope: "Today's GPU rental prices: the price index in USD per GPU-hour for each GPU," and enumerates the returned fields (1-day/1-week/1-month changes, index day, page link). It also explicitly contrasts itself with get_price_history and get_provider_prices, so an agent can distinguish it from siblings without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit routing rules — "For past values use get_price_history; for providers' posted prices get_provider_prices" — plus concrete example phrasings ("what does an H100 cost per hour?"). Both when-to-use and which alternative to pick are stated, not inferred.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
