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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed-world scope, so the safety profile is fully covered. The description's real contribution is the 'newest first' sort order, which annotations can't express; it says nothing about truncation or what happens beyond the limit.

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?

One sentence, no waste, with the resource and ordering front-loaded where an agent scanning the list will see them first.

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?

With an output schema covering return values and annotations covering safety, the description only needs scope and ordering, both of which it supplies. It is thin on the lone parameter, but nothing required to call the tool correctly is missing.

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 0% and the description never mentions the single 'limit' parameter, so it adds no explicit parameter meaning. However, the schema itself carries default=10, minimum=1 and maximum=20, making the parameter close to self-documenting, and 'latest' loosely implies bounded recency rather than full history.

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?

Specific verb+resource ('List ... template runs') plus scope ('the user's latest'), ordering ('newest first'), and returned fields ('status and result links'). It clearly separates itself from get_run (single run) and list_creations (a different resource), though it never names those siblings explicitly.

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 phrase 'latest ... runs' implies this is the browse/recent-activity view as opposed to get_run's single-record lookup, but the choice is left to inference. There is no explicit 'use this when...' statement and no exclusion of alternatives.

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