get_client_identity

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered structurally. The description adds the notable nuance that no execution or target attachment occurs, plus what identity fields are surfaced, but does not cover prerequisites (e.g., a client must be configured) or failure behavior.

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 subject of the read and the non-invasive constraint are both packed into one clause.

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 rich annotations, an output schema, and no parameters, the description carries little additional burden and covers the essentials. It could still note the precondition of an already-configured client to be fully complete, but nothing critical for correct invocation is missing.

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?

The tool takes zero parameters, which is the baseline-4 case; there is no parameter surface for the description to explain. The description's mention of 'configured client' implicitly tells the agent which client the result pertains to, but no argument semantics are needed.

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 specific verb ('Read') and a concrete resource set ('configured client ELF hash, Build ID and architecture'), so an agent knows exactly what data comes back. It is distinguishable from the sibling get_capabilities by resource, though it never names or contrasts that sibling 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?

The phrase 'without executing or attaching' implies the safe, passive-read scenario where this tool applies rather than an active debug/inspection path. However, there is no explicit when-to-use guidance and no comparison to the sibling get_capabilities, leaving selection to inference.

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