Update Workout Template Name

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

With no annotations, the description carries the full burden and does well: it discloses in-place mutation, the matching behavior (fuzzy by name or exact by id), and the explicit side-effect of not touching exercises. It doesn't mention failure modes or conflict handling, but the core behavioral traits relevant for an agent are present.

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?

Two crisp clauses covering action, scope, and behavior. No fluff, no repetition of schema fields. Every word earns its place and the core action is 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?

For a simple two-parameter rename tool with no output schema and no annotations, the description is largely complete: it tells the agent what the tool does, how matching works, and what it will not affect. It stops short of specifying return values or conflict behavior, but those aren't necessary given the operation's simplicity.

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 100%, so parameters are already documented. The description adds value by explaining how the 'template' parameter is interpreted (fuzzy-matched by name, exact by id), which goes beyond the schema's simple 'name or id' note. This extra semantics helps with correct invocation.

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?

Description uses a specific verb ('Renames'), names the exact resource ('existing workout template'), and adds a crucial scope qualifier ('Doesn't touch its exercises'). This clearly distinguishes it from the sibling update_workout_template, which presumably updates other template aspects.

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 usage: use when you need to rename a workout template without affecting its exercises. However, it does not explicitly state when to prefer this tool over update_workout_template, nor does it mention any exclusions or alternatives. The 'doesn't touch its exercises' gives a hint but isn't an explicit routing instruction.

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