xae_open_solution

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety/mutation profile is largely covered. The description adds only the implicit precondition that a shell must be attached; it says nothing about what happens on failure, whether the solution replaces the current project state, or whether it triggers a build/load.

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 short sentence with the action front-loaded and no filler. It is efficient, though brevity here shades into under-specification rather than tight, information-dense writing.

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?

An output schema exists, so return-value explanation is not required, but the lone parameter is undocumented and the dependency on a prior attach is only implied. For a simple one-parameter tool that is minimally adequate, not complete.

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 0% for the single required 'path' parameter, so the description carries the full burden and fails to add anything: no expected format (.sln extension, absolute vs relative, escaping). An agent must guess what a valid path looks like.

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 names a specific verb (Open) and resource (.sln solution file) and clarifies the operating context ('in the attached shell'). It does not, however, distinguish this from nearby siblings like xae_boot_project or xae_attach, so an agent must infer which entry point applies.

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 versus xae_attach, xae_boot_project, or xae_activate_configuration, and no prerequisites (e.g. that a shell must already be attached). The phrase 'attached shell' hints at a precondition but never states it or tells the agent what to do if none exists.

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