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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=true, so the safety profile is covered. The description usefully adds that renaming does not propagate to existing job copies, which is real behavioral context the annotations cannot express, but it says nothing about the idempotency/request-id replay semantics implied by the annotations.

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?

A single sentence with the action front-loaded and zero filler. Nothing could be removed without losing meaning.

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 mutation tool with zero schema description coverage and no output schema, one sentence is thin. It leaves unanswered what happens on success, how request_id/idempotency_key govern retries, and whether the rename is reversible or rejected on partial matches.

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% across four parameters, and the description contributes nothing about any of them. Names like starter_id and name are self-explanatory, but request_id and idempotency_key carry replay/deduplication semantics that are never explained here or in the schema.

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?

States a specific verb (Rename) and resource (organization starter) and adds a scope qualifier ('without changing existing job copies') that separates it from other starter mutations. It does not name any sibling explicitly, but the verb-resource pairing is unambiguous against create/delete/apply/save_job.

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?

There is no when-to-use guidance, no prerequisites, and no reference to alternatives such as yardstick_automation_starters_create or save_job. The only routing hint is the implicit contrast with operations that do copy jobs, which is a side effect of the scope note rather than deliberate guidance.

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