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

Annotations already declare readOnlyHint=false, destructiveHint=true, and openWorldHint=true, so the agent knows this is a state-changing, open-world operation. The description adds only the deprecation status and says nothing about what gets mutated, spend behavior (despite a max_price_usd param), or authorization needs.

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?

A single clause with zero waste; the deprecation notice and the replacement are front-loaded. It is terse by design for a deprecated endpoint, though it is under-specified rather than optimally efficient.

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?

Has an output schema and annotations, which reduces the burden, but a 4-parameter operation tool with a deprecation notice gives no information about what it executes or whether it remains functional. For an agent deciding between this and batch_use, the description is thin.

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 100%, so all four parameters (operation_id, arguments, search_id, max_price_usd) are already documented in the schema. The description adds no parameter meaning on top, so the baseline 3 applies.

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 never states what the tool does — no verb or resource. It only labels the tool as deprecated and points to a replacement, leaving the actual capability ('Run an AIsa operation' from the title) unexplained. An agent must infer the purpose from the title and schema alone.

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?

It explicitly routes the agent to the alternative ('use batch_use instead'), which is exactly the guidance needed for a deprecated tool. It doesn't explain when, if ever, this tool should still be called (e.g., during a migration window), so it stops short of a 5.

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