get_index

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

With no annotations, the description bears the full transparency burden. It discloses that output is automatically stored, returns an object ID, and advises using object store tools. This gives clear behavioral context beyond a simple fetch, though it does not mention permissions or rate limits.

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 moderately concise but includes a param docstring that could be integrated more tightly. It has some redundancy (mentions 'index_name' twice) and advice that, while helpful, adds length. Could be streamlined.

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?

There is no output schema, so the description explains the return format (formatted preview with object ID) and how to use it (object store tools). This makes the tool usable, though it could detail the configuration content slightly more. Overall sufficient for a simple fetch tool.

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% (no descriptions in schema), but the description includes a ':param index_name: Unique name of the index to fetch.' line, adding meaning beyond the type alone. It compensates well for the schema gap.

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 uses 'Fetches detailed configuration information for a specific index,' clearly stating the action and resource. It distinguishes from siblings like list_indexes (which lists all) and other get_* tools by specifying the target is a single index.

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 implies usage for fetching configuration of a specific index but does not explicitly state when to use this tool over alternatives (e.g., list_indexes for listing all, or update_index for modifications). No when-not or alternative guidance is provided.

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