link_estimate_to_project

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

Annotations already indicate it's not read-only (readOnlyHint=false) and not inherently destructive (destructiveHint=false). The description adds that it 'makes it the active estimate system', which clarifies the effect. However, it does not disclose side effects like overwriting a previous active estimate or authentication requirements. Given annotations, this is acceptable but could be richer.

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 extremely concise: one sentence for the action, then clear Args and Returns sections. Every word earns its place. No fluff, perfectly front-loaded.

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?

Given the low complexity (2 required params, output schema exists, annotations present), the description provides sufficient information to understand the tool's function and output. However, it lacks mention of error conditions or prerequisites, which would make it more complete. Still, it meets the needs for a simple linking operation.

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 0% schema description coverage, the description must add meaning. It lists both params with their roles (project_id, estimate_id) and mentions UUID type, but does not provide additional context such as where to obtain IDs or constraints. This adds some value beyond the bare names but is minimal.

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 'Link' and identifies the resources 'estimate to a project', clearly stating the outcome 'making it the active estimate system'. This distinguishes it from sibling tools like create_project_estimate (which creates a new estimate) and get_project_estimate (which retrieves the current estimate).

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 implies when to use the tool (to set an existing estimate as the active one for a project) but does not explicitly mention when not to use it or provide alternatives among siblings. The usage context is somewhat clear but lacks explicit guidance.

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