v6.5.1Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the high-level outcome and does not mention return format, error behavior, side effects, or what happens when the id does not exist.
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 one short, front-loaded phrase with no filler or redundant information. It is appropriately sized for a simple one-parameter retrieval tool.
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 one-id getter, the description is minimally workable, but it lacks an output schema and does not explain how to obtain a valid id or what format the content will be in. Mentioning the relationship to engine_history_list would make it substantially more complete.
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?
The schema has 0% description coverage, but the description minimally clarifies that 'id' refers to a saved version id. For a single integer parameter this may be sufficient, yet it adds no detail about the type, source, or expected format beyond the schema and name.
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 identifies the resource (one saved version) and the lookup key (id), so an agent can infer it retrieves content for a specific version. It also implicitly contrasts with sibling engine_history_list, though it lacks an explicit verb like 'retrieves' or 'gets'.
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 gives no guidance on when to use this tool versus alternatives such as engine_history_list, nor does it mention any conditions, exclusions, or related workflow. Usage context is only implied by the phrase 'one saved version by id.'
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
