Update post

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the useful behavioral constraint that only allow_comments can be changed, but it does not describe side effects, authorization requirements, or what happens to other fields.

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?

Two short sentences with zero waste. The purpose is front-loaded, and the mutation constraint follows immediately, so the definition is easy to scan and parse.

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 two-parameter mutation tool with annotations covering safety, the description gives the essential mutable-field constraint. However, it omits sibling differentiation, usage context, and any note about return behavior, leaving clear gaps for an agent choosing among many update-oriented 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?

Schema description coverage is 0%, so the description must compensate. It does clarify that allow_comments is the only mutable field inside the nested data object, but it offers no meaning for post_id and does not explain the required data wrapper, leaving partial coverage of the two parameters.

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 clear verb (update) and resource (post), and adds a crucial scope constraint that only allow_comments can be changed. However, it does not differentiate this tool from the sibling reddit_ads_update_structured_post, which also updates a post-like resource, leaving an agent to infer the distinction.

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 provides no guidance on when to use this tool versus alternatives such as reddit_ads_update_structured_post or other update operations. It only states a constraint on what can be changed, not the context or conditions that select this tool.

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