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

The readOnlyHint annotation is consistent with the 'List' action, and the description clarifies the output includes hasUpdate and usage ids. It does not overstate side effects, and the read-only behavior is clear from both the annotation and the verb used.

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 two sentences and contains no fluff or redundancy. It front-loads the core purpose and adds only the most relevant cross-tool detail.

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?

The description gives enough context for an agent to call the tool correctly: it names the resource, the key output field (hasUpdate), the downstream use of usage ids, and the context requirement. It does not describe the full response shape, but for a simple read-only list tool that omission is acceptable.

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 descriptions fully cover specId and versionId, so baseline is appropriate. The description adds no extra parameter-level detail beyond what the schema already provides, but it does clarify that specId refers to the specification whose component usages are being listed.

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 states the tool lists which shared-library components a spec links, including update availability via hasUpdate. It identifies the resource and action unambiguously, with no confusion against sibling list tools.

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 explains that returned usage ids are what manage_shared_component_link needs for 'unlink' and 'accept_update', and notes that project context is required. It could be stronger by explicitly stating when to choose this tool over alternatives, but the guidance is useful and relevant.

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