Create or Update Redshift AOV

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

With no annotations provided, the description alone must convey safety and side effects. The text discloses that the operation can create or update, but it doesn't state whether the update overwrites existing settings, whether other AOVs are untouched, what preconditions exist, or what response the caller should expect. This is very thin for an annotation-free mutation tool.

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?

One sentence, front-loaded with the core verb and resource, with no filler. Every word earns 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 9-parameter tool with no output schema and no annotations, this description is not complete enough. It explains the identity pair but leaves the update semantics, optional parameters, effect on existing AOVs, and return behavior unspecified, so an agent would struggle to invoke it correctly with confidence.

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 only 44%, so the description needs to explain the remaining parameters. It adds value by clarifying that type and name together form the identity pair, but it says nothing about the 'params' object or other optional fields such as enabled, document_name, render_data_name, direct_file_path, multipass_enabled, or direct_file_enabled.

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 clearly identifies the action ('Create or update') and the target ('Redshift AOV type/name pair'), and the word 'exact' distinguishes it from bulk AOV tools like rs_clear_aovs or rs_configure_render. However, it does not explicitly name sister tools, so it isn't fully differentiated on its own.

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 phrase 'Create or update one exact... pair' implies this is the tool to call when you want to ensure a single AOV exists with a specific identity. But it gives no explicit guidance about when not to use it, nor does it mention alternatives such as rs_list_aovs, rs_remove_aov, or batch-oriented tools.

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