list_config_indexer

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

The description is consistent with annotations (readOnlyHint=true, idempotentHint=true, destructiveHint=false) and adds the exact GET endpoint, but does not provide additional behavioral context such as response shape, configuration scope, or any edge cases. It is adequate but minimal.

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 clear sentence plus the endpoint. It is tightly focused, front-loaded with the action and resource, and contains no filler or redundant wording for a zero-parameter read operation.

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 simple read-only tool with no parameters, rich annotations, and an output schema, the description is largely complete. It includes the HTTP method and path needed to call the tool correctly, though it could better clarify the scope of 'IndexerConfig' relative to sibling config tools.

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?

This tool has zero parameters, so the input schema already covers all parameter semantics completely. The description does not need to compensate for any missing parameter documentation, and the 100% schema coverage makes this a non-issue.

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 the explicit verb 'Read' and the resource 'IndexerConfig', and the endpoint 'GET /api/v3/config/indexer' clarifies the exact operation. It is clear, but it does not differentiate itself from siblings such as list_config_downloadclient or get_config_indexer_by_id.

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?

No guidance is provided on when to use this tool versus the many similar siblings, such as get_config_indexer_by_id or list_indexer. The description implies it is for reading the indexer config but does not state when to prefer it or what distinguishes it.

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