get_global_schema

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

With no annotations, the description carries the disclosure burden. It does reveal that schemas are merged and the operation runs in parallel, but it does not explicitly state that this is a read-only aggregation or describe how conflicts between profile schemas are resolved. Still, nothing contradicts the tool's apparent 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?

The description is a single sentence that packs the action, scope, execution mode, and a grouping tag. Every word earns its place and nothing is redundant.

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, low-complexity tool, the description is nearly sufficient to invoke correctly. It could be slightly more explicit about the return value's structure and that the operation is read-only, but those are minor gaps given the simple interface.

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 has zero parameters, so the baseline is 4. The description adds useful context by defining what gets merged, but no parameter details 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?

Description uses a specific verb ('merge') and a clear resource ('all enabled profiles' schemas into a global schema). It also mentions parallel execution, and the scope of 'all enabled profiles' distinguishes it from sibling tools like get_schema, which target a single profile.

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 intended use is implied: call this when you need the combined schema across all enabled profiles. However, it does not explicitly say when not to use it or name alternatives like get_schema or compare_profile_schemas, so the agent must infer the routing.

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