bookshelf_test_all_indexer

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

The description adds 'WRITE: this modifies your Bookshelf instance,' which is consistent with readOnlyHint=false but adds no new behavioral information beyond what annotations already provide. There is no disclosure of side effects, whether tests run asynchronously, or what the operation actually does to indexers.

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 short and not verbose, but the first sentence 'Create indexer testall' is unclear and fails to effectively front-load purpose. The second sentence is a redundant warning. Overall it is concise in length but not optimally structured.

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 does not clearly state that the tool tests all indexers, nor does it explain the operation's effects or when it should be used. Even with an output schema and no parameters, the missing clarity about core functionality leaves the description incomplete.

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 input schema has zero parameters, so the description has no parameters to explain. Per the rubric, 0 params earns a baseline of 4. The description does not introduce any param-related ambiguity.

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 'Create indexer testall' is vague and awkwardly phrased; it is unclear whether the tool creates something called 'testall' or tests all indexers. The tool name better suggests the actual purpose than the description, but the description does not clearly state a specific verb and resource.

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 alternatives like 'bookshelf_test_indexer' (singular). It only states a generic write warning, leaving the agent without context about appropriate scenarios.

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