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

Annotations already cover readOnly/idempotent/non-destructive, and the description adds real value on top: the result is a signed download link delivered as file_url, it requires the API key header, and the response also carries the asset edit page. Missing is any note on link expiry or failure modes for a non-Compute asset_id, which is the remaining behavioral unknown.

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 compact clauses with the most decision-relevant fact (DEPRECATED) front-loaded, followed by the payoff and auth requirement. The stacked parentheses make it dense to parse but nearly every token carries information; only the trailing 'Free' is low-value.

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 two-parameter read-only tool with no output schema, the description covers what is returned (file_url plus edit page), the auth prerequisite, and the deprecation status. The one thing an agent still cannot resolve from the definition is what asset_id must refer to and when workspace_id is needed.

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?

Only workspace_id carries a schema description (50% coverage), and the description does not document it at all; asset_id is undocumented in both places, with the phrase 'one Compute GLB' merely implying it is the target asset identifier. The API-key-header remark is auth context rather than parameter semantics, so this sits at the baseline rather than compensating for the coverage gap.

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 and resource ('Signed-in download link of one Compute GLB') and immediately identifies itself as 'DEPRECATED alias of gripforge_library_get (same signed library file)', so an agent can separate it from gripforge_compute_assets, gripforge_compute_variant and the other compute siblings without opening a schema.

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 leading 'DEPRECATED alias of gripforge_library_get' effectively tells the agent which tool to prefer and that this is the fallback, with the parenthetical note that both return the same signed library file. It stops short of an explicit 'use X instead' imperative or any condition under which calling the alias is still appropriate, so it is clear context rather than full when/when-not guidance.

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