link_project_to_product

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

With no annotations provided, the description carries the burden of disclosing behavioral traits. It does not state whether links are idempotent, whether it overwrites existing links, what happens if the project is already linked, or what the response looks like. The description is too sparse to convey any side effects, permissions, or other operational details.

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, front-loaded with the action, and contains no filler. It is concise, but slightly under-specified for the broader context, making it somewhat too terse. Still, it earns its place and is well-structured for a simple linking operation.

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?

There is no output schema and no annotations, so the description must compensate by explaining what the tool returns or how it behaves. It only states the action without addressing outcomes, error conditions, or the effect on existing relationships. For a tool that modifies an association, this is a significant gap.

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 input schema already provides descriptions for all three parameters (product_id, project_id, is_primary), achieving 100% schema coverage. The description itself does not add further meaning beyond the schema, so a baseline score of 3 is appropriate. No additional parameter clarification is 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?

The description clearly states a specific action: linking an existing project to a product. It uses a precise verb ('link') and identifies both the object and the target, distinguishing it from sibling tools like create_project, create_product, or update_project. No ambiguity about the tool's core function.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or constraints. There is no mention of when linking is appropriate, whether the project/product must already exist, or any exclusions. For a tool that associates two existing entities, this leaves the agent with little context for decision-making.

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