Associate Equipment With Project (Company)

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

Annotations indicate the tool is not read-only (readOnlyHint=false), not destructive, and not idempotent. The description adds that it 'Creates a new Equipment records' and returns HTTP 201, which aligns with the annotations. However, it does not disclose any additional behavioral traits such as required permissions, rate limits, or side effects beyond the creation.

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 three sentences long, front-loading the action and resource. It concisely mentions the required parameter and the API endpoint. While it could be tighter by combining sentences, it is efficient and avoids unnecessary words.

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?

The description fails to explain what 'associate' means in this context, whether a project ID is needed (only company_id is in schema), and what the created equipment record contains. It does not mention prerequisites or the full request body. Given the lack of output schema, more detail about the return object and the association semantics is needed for completeness.

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?

With 100% schema description coverage, the input schema already documents the single parameter 'company_id' as a path parameter. The description only restates that it is required, offering no additional semantics or usage details. Thus, no value is added 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?

The description uses a specific verb 'associate' and identifies the resource 'equipment with project (Company)'. It distinguishes from the sibling tool 'associate_equipment_with_project_project' by including '(Company)' in the title and description, making the scope clear. However, it does not explicitly contrast the two, leaving some ambiguity.

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 description states 'Use this to perform the associate equipment action on Equipment records' but provides no guidance on when to use this tool versus the project-level variant. No exclusion criteria or alternative suggestions are given, failing to help the agent choose correctly among siblings.

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