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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It discloses that the tool mutates a Library item and can manually detach/relink a Superseded version, but it does not state whether changes are reversible, what side effects occur on linked versions, whether permissions are required, or what the response contains. For a mutation tool with zero annotation coverage, this is a significant gap.

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 sentence with no filler and front-loads the primary purpose. It is concise, though it could be slightly more structured by separating the two operation types.

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 mutation tool with no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It does not explain the effect of successorId null, whether groundingEnabled is required for the availability change, or what happens to a Superseded item when relinked. An agent would need to open the schema and guess at semantics.

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%, so the description must compensate, but it only loosely maps to the parameters: 'agent availability' likely maps to groundingEnabled, and 'detach/relink a Superseded version' maps to successorId. itemId is implied as the target. The description does not explain the semantics of successorId null vs a UUID, nor the meaning of groundingEnabled, leaving the agent to infer parameter meaning from names alone.

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 states a specific verb ('Change') and resource ('Library item'), and names two distinct operations: changing agent availability and detaching/relinking a Superseded version. It is clear enough to distinguish from siblings like devtune_read_library_item and devtune_upload_library_item, though it does not explicitly name a sibling alternative.

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 gives no guidance on when to use this tool versus alternatives such as devtune_update_knowledge_profile or devtune_upload_library_item. It implies usage through the operation description but does not state prerequisites, when not to use it, or which sibling covers related update scenarios.

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