get_backplane_history

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description adds minimal behavioral info beyond confirming it's a retrieve operation. The word 'historical' clarifies the scope, but no additional traits (e.g., error handling, auth requirements) are disclosed.

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, well-crafted sentence that immediately conveys the tool's purpose. There is no redundancy or unnecessary information.

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 tool's simplicity (single parameter, output schema exists), the description covers the core purpose but omits important context about the parameter semantics and return value. The output schema helps, but the parameter gap reduces completeness.

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%, yet the description only says 'by id' without explaining what the 'backplane_id' represents (e.g., the unique identifier from 'list_backplane_history'). The parameter title 'Backplane Id' is not expanded upon, so the description fails to compensate for the missing schema description.

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 ('retrieve'), identifies the resource ('historical backplane connection'), and specifies the lookup key ('by id'). This clearly distinguishes it from the sibling 'list_backplane_history' (which returns multiple) and 'get_backplane' (which returns current, not historical).

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 the tool is for fetching a single historical record by its ID, but it does not explicitly state when to use it over alternatives like 'list_backplane_history' or 'get_backplane_history_media_streams'. No exclusions or context are provided.

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