get_default_profile

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

No annotations are supplied, so the description carries the full burden. 'Show' implies a read-only, side-effect-free operation and the mention of overridable defaults gives useful framing, but it says nothing about return format, whether the values are static, or any preconditions.

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 well-formed sentence with no filler, and the key concept (baseline settings that carrier profiles override) is front-loaded.

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 zero-parameter getter the description covers the basic intent, but with no annotations and no output schema the agent has no idea what shape the returned settings take. That is a real gap, though a modest one given the tool's simplicity.

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, so the schema-coverage baseline is 4. There is nothing parameter-related the description could usefully add.

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 gives a specific verb ('Show') and a specific resource ('baseline validation settings that a carrier profile can override'), which tells an agent this is a read of default configuration. It stops short of naming the 834 context or distinguishing itself from siblings like validate_834, so the differentiation is only implicit.

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 and no mention of alternatives. The phrase 'that a carrier profile can override' hints at a relationship to carrier-profile tools, but the agent must infer when to call this versus validate_834 or the setup tools.

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