bookshelf_update_qualitydefinition

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

The description repeats the write nature already indicated by readOnlyHint=false in annotations. It adds no new behavioral context beyond restating that the operation modifies the instance.

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 very short, but the second sentence ('WRITE: this modifies...') is redundant given annotations. It is minimally informative.

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 a flexible body parameter and an output schema, the description is incomplete. It doesn't explain what fields can be updated or the effect beyond a generic 'modifies' statement.

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?

No parameter details are given. With 0% schema description coverage, the description fails to explain the required 'id' parameter or the flexible 'body' object.

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 updates a qualitydefinition and that it modifies the instance. However, it does not differentiate from the sibling tool 'bookshelf_update_quality_definitions' (plural), which likely handles bulk updates.

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 provides no guidance on when to use this tool versus the get/list/update variants. There is no mention of alternatives or specific use cases.

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