Update structured 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 one genuinely useful behavioural fact: the mutation is limited to allow_comments and other fields cannot be changed. It does not mention permission requirements or what a successful update returns.

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 immediately follows. Nothing extraneous is present.

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 single-field mutation tool with no output schema, the essentials are covered but barely. It omits what happens on success/failure and any auth or precondition context, leaving the definition thin for a write operation.

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 carry parameter meaning and it only partly does. It identifies allow_comments as the sole mutable field but says nothing about the required post_id or the nested data wrapper, leaving the schema to communicate structure with no prose support.

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?

States a specific verb+resource ('Update a structured post'), which matches the tool name and distinguishes the resource from the plain post siblings like reddit_ads_update_post. It is clear but does not explicitly disambiguate against siblings such as update_post or get_structured_post.

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 constraint 'Only allow_comments can be changed' gives implicit guidance about what the tool is for, but there is no explicit when-to-use, no alternative-naming, and no prerequisites (e.g. that the post must exist). Usage is left to inference.

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