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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the agent knows this is a safe, local read. The description adds only the shape of the returned data (optimization state, performance metrics) and nothing about permissions, currency of the snapshot, or rate limits.

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 front-loaded sentence with no filler; the key noun ('status of an agent') comes first and the payload detail follows. It earns its place but is minimal.

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?

For a read-only getter with no output schema, the description gives a useful hint about returned fields, but it omits whether status is live or cached, and does not help disambiguate from get_agent. Adequate but with clear gaps.

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 coverage is 100%, so both agentId and the superadmin-only customerId are fully documented in the schema. The description adds no further parameter meaning, which is the expected baseline when the schema does the heavy lifting.

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?

States a clear verb ('Get') plus resource ('agent status') and names the payload contents (optimization state, performance metrics), which helps an agent predict the response. However, it does not differentiate itself from the sibling get_agent or get_model_optimization_status, so the agent must guess which retrieval tool to pick.

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 statement of when to use this tool versus the many other 'get_*' retrieval siblings (get_agent, get_model_optimization_status, analyze_agent), nor any prerequisites or exclusions. Usage is only implied by the name.

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