List missing updates for an endpoint

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds that each returned item has an id usable for deploy, which is useful behavioral context. It does not contradict annotations and provides a meaningful supplement.

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?

The description is extremely concise with two sentences, front-loading the core purpose and a key usage note. No wasted words, making it efficient for an AI agent to parse quickly.

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?

Given the presence of an output schema (so returns need not be described) and comprehensive annotations, the description covers the essential purpose and a critical usage link (deploy). It does not explain optional parameters like limit or response_format, but these are already documented in the schema. Adequate for a simple list tool.

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 the input schema already documents all four parameters comprehensively. The description adds no additional meaning beyond what is in the schema, hence a baseline score of 3 is appropriate.

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?

Description clearly states the tool returns missing-update items for one endpoint, with a specific verb 'returns' and resource 'missing-update items'. It distinguishes from siblings like action1_list_updates by specifying 'for one endpoint' and links to deployment via item.id, making its purpose unambiguous.

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?

Description implies usage context by noting that item.id can be passed to action1_deploy_update, indicating this tool is a prerequisite before deploying updates. However, it does not explicitly state when not to use this tool or mention alternatives, so it lacks explicit exclusion guidance.

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