create_indexer_testall

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

Annotations already declare idempotent and non-destructive behavior, so the description does not need to restate those. However, the description adds no context about what 'testall' actually does, what side effects occur, or what an agent should expect after invocation.

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, but the opening phrase 'Create Indexer' is under-specification rather than meaningful conciseness and likely restates a misleading intent. The endpoint line is useful, but the overall content does not earn its place.

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 tool with no parameters and an output schema, the basic mechanics are simple, but the semantic context is missing. An agent cannot determine that this is the test-all-indexers operation or how it relates to create_indexer_test.

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 tool has zero parameters and the schema coverage is effectively complete. There is no parameter meaning for the description to add, so it cannot be penalized for missing parameter guidance.

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 says only 'Create Indexer,' which omits the 'testall' action and does not distinguish this tool from siblings like create_indexer or create_indexer_test. Given the endpoint POST /api/v1/indexer/testall, the stated purpose is misleading rather than clarifying.

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?

There is no guidance about when to use this tool or why it is preferable to create_indexer, create_indexer_test, or create_indexer_action_by_name. The description implies a creation workflow that the endpoint does not support.

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