add_favorite

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

With no annotations, the description must disclose behavioral traits. It only states the action is add or remove, without explaining persistence, side effects, idempotency, or whether the 'add' action creates a favorite record. Missing critical behavioral 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 brief and to the point, with a clear args list. No wasted words, but it could be better structured with a summary of what 'favorite' means. Still, it earns its place.

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 number of sibling tools (15), the description lacks context on how this tool fits into workflows. It does not mention that 'project_favorites' lists favorites, nor does it explain the concept of favorites. Incomplete for a simple mutation tool.

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%, so the description adds value by explaining the source of project_id and domain_id (from other tools) and the default for action. This goes beyond the schema's type/title info, though it does not explain the meaning of 'add' or 'remove'.

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 the verb 'Add or remove' and resource 'domain from a project', making the purpose evident. However, it does not explicitly distinguish this tool from sibling tool 'project_favorites', which likely lists favorites.

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 guidance on parameter sources (project_id from list_projects, domain_id from search results), implying usage context. However, it lacks explicit instructions on when to use add vs remove, or when not to use this tool.

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