searchidx_add_autocomplete

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only implies mutation through the word 'add.' It does not state what files or configurations are modified, whether the operation is reversible, or whether an api_key is required for side effects.

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 extremely brief with no wasted wording, but it is under-specified rather than appropriately concise. A single phrase that restates the tool's name leaves out essential context an agent would need.

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 no annotations and no output schema, this description is incomplete. It does not explain what autocomplete is added to, what api_key is for, what is changed on disk, or what success looks like, so an agent cannot confidently invoke it beyond guessing.

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 description adds no information about either parameter. The schema itself documents only 'directory' with 'Project directory,' leaving 'api_key' completely unexplained, and the description does not compensate for that 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 states a specific action—add search autocomplete—with a clear verb and resource. However, it does not distinguish this tool from related siblings like searchidx_setup or searchidx_optimize, and it is essentially a slight expansion of the tool name.

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 alternatives. The description does not mention prerequisites, such as whether a search index must already exist, nor does it name any sibling tool to prefer in other situations.

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