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

The annotations already disclose readOnlyHint=false, destructiveHint=false, and openWorldHint=true. The description confirms a rename operation but adds no behavioral context such as permissions required, reversibility, side effects, or whether other goals are affected.

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 short sentence with no filler, and the core action is front-loaded. It is appropriately sized, though the phrase "from list_training_goals" is slightly awkward and carries most of its meaning through implication.

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?

For a simple two-parameter mutation tool, the description is minimally adequate: it identifies the action and the source of goalId. However, it leaves half the schema undocumented and does not clarify the name parameter or the operation's behavioral expectations.

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 coverage is 50%, with only goalId documented as "Id from list_training_goals." The description restates that source and implies that "name" is the new name, but it adds no constraints or format details for the name parameter.

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 and resource: "Renames a training goal," and ties it to the source list via "from list_training_goals." It is clear what the tool does, though it does not explicitly distinguish itself from siblings such as create_training_goal or update_goal.

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?

Usage is only implied: the agent can infer that an existing training goal must first be obtained from list_training_goals. The description gives no explicit guidance about when to rename versus create or update a goal, and no exclusions or alternatives are stated.

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