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

Beyond the annotations, the description explains the cost model (hours x hourly yields a ceiling in micro-USD) and clarifies what the resulting reserve means, an initial hold rather than total cost. That also reconciles with readOnlyHint=false, since a reservation hold is a state change, so nothing is contradicted.

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

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

Two short sentences with the scope and pricing formula front-loaded, and no filler. The second sentence is terse but still carries real information about reserve semantics.

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

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

With 8 undocumented parameters, no output schema, and several overlapping/ambiguous fields (node/nodes/count/model), the description does far too little to guide correct invocation. It explains the pricing math but not how to populate the inputs or what the response contains.

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

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

Schema description coverage is 0% across 8 parameters, and the description only hints at the node count ('1-4 nodes', matching the `nodes` parameter). It says nothing about the ambiguous overlaps between `node` vs `nodes`, `count` (max 8) vs `nodes` (max 4), `model`, `minVram`, `environment`, or how `maxMinutes` relates to the 'hours' in the formula.

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

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

The description states a specific verb and resource: quote 1-4 nodes for an experiment, with the pricing formula (hours x hourly, micro-USD). The 'for an experiment' qualifier separates it from sibling quote tools such as emt_quote and emt_cluster_quote, though it does not name those siblings explicitly.

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

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

There is no explicit when-to-use guidance: the description never says to call this before emt_rent or emt_start_experiment, nor when to prefer it over emt_quote or emt_cluster_quote. Usage is only implied by the word 'Quote'.

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