init_rack

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

Annotations declare destructiveHint=true and readOnlyHint=false, yet the description says nothing about overwriting an existing rack definition, losing previously mounted equipment references, or permission requirements. For a destructive mutation tool, this is a substantial gap; the description adds no behavioral context beyond the annotations.

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 compact sentence with the key fields front-loaded and no filler. It could be marginally sharper by clarifying that the clearances refer to front/rear door clearances rather than 'enclosure clearances' as an abstraction.

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?

A 7-parameter destructive initialization tool with no output schema needs to say what state is created or replaced and how it relates to sibling setup tools. The description omits the overwrite consequence, defaults behavior, and ordering relative to mount_equipment, leaving the agent under-informed.

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 100%, so every parameter (including enums and defaults) is already documented, establishing a baseline of 3. The description names some fields generically ('U height, rail depth, enclosure clearances') but adds no semantics beyond the schema.

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 (Initialize) and resource (rack) plus the configurable dimensions: standard, U height, rail depth, clearances. It is distinguishable from siblings like mount_equipment and validate_rack, though 'initialize' leaves mild ambiguity about whether it creates persistent rack state or just sets configuration.

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?

No indication of when to call this versus siblings, and no prerequisites stated. The word 'Initialize' weakly implies a first setup step, but nothing tells the agent it must precede mount_equipment or that re-calling replaces prior configuration.

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