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

No annotations are supplied, so the description carries the full burden. It does disclose the return payload (block list, connection wiring, C# build code), which is the key behavioral fact for a lookup tool, but says nothing about whether the template is static, what happens with an unrecognized use case, or that the operation is read-only and side-effect free.

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 tight sentences with no filler: purpose first, return shape second. Every clause earns its place, and the return-value sentence is especially valuable given there is no output schema.

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 no output schema, the description compensates by describing what comes back, and the single parameter is fully documented in the schema. Only routing guidance relative to sibling tools is missing, which is a minor gap for a simple one-parameter lookup.

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 100% and the sole parameter already enumerates all eight accepted template values with explanations. The description adds no syntax, casing, or fallback detail beyond 'a specific use case', so the schema is doing all the work — baseline 3.

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 gives a specific verb and resource ('Get a media block pipeline template') and scopes it to 'a specific use case', which distinguishes it from lookups like get_media_block_info or get_code_example. It stops short of naming a sibling to contrast against, so the boundary is inferred rather than stated.

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 explicit when-to-use or when-not-to-use guidance, and no alternative is named despite several plausible siblings (get_code_example, get_media_block_info, list_media_blocks). The phrase 'for a specific use case' implies a scaffolding scenario but leaves the agent to infer it.

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